スプリング部材８６は、第２の摺動部７５が上記のように駆動シリンダ８２で引かれている最中に、第２の検出部２４の第２のローラ６１および第２の支持部材６２と第２の揺動部２２と第２の摺動部７５とが停止しても、伸びることで、これらと移動部材８１との移動量の差を吸収して、この停止を許容する。 In the spring member 86, while the second sliding portion 75 is being pulled by the drive cylinder 82 as described above, the second roller 61 of the second detection portion 24 and the second support member 62 and the second support member 62 are used. Even if the swinging portion 22 of 2 and the second sliding portion 75 stop, they are stretched to absorb the difference in the amount of movement between them and the moving member 81, and this stop is allowed.

駆動シリンダ８２が後退状態から、移動部材８１を前進させて待機状態となると、金属カラー部材８５に連結された第１の摺動部７１およびスプリング部材８６に連結された第２の摺動部７５が駆動シリンダ８２側とは反対に移動する。すると、第１の上部ピン４２および図示略の第２の上部ピンが駆動シリンダ８２とは反対側に移動し、第１の揺動部２１および第２の揺動部２２が支持軸３３を中心に揺動して第１の下部ピン４１および第２の下部ピン４５を第１の上部ピン４２および図示略の第２の上部ピンとは逆方向に移動させる。その結果、第１の支持部材５２と共に第１のローラ５１が後退して待機位置に戻り、第２の支持部材６２と共に第２のローラ６１が後退して待機位置に戻る。 When the drive cylinder 82 advances the moving member 81 from the retracted state to the standby state, the first sliding portion 71 connected to the metal collar member 85 and the second sliding portion 75 connected to the spring member 86 Moves in the opposite direction to the drive cylinder 82 side. Then, the first upper pin 42 and the second upper pin (not shown) move to the side opposite to the drive cylinder 82, and the first swing portion 21 and the second swing portion 22 are centered on the support shaft 33. The first lower pin 41 and the second lower pin 45 are moved in the opposite directions to the first upper pin 42 and the second upper pin (not shown). As a result, the first roller 51 retracts together with the first support member 52 and returns to the standby position, and the second roller 61 retracts together with the second support member 62 and returns to the standby position.

測定部２５は、図３および図４に示すように、第１の摺動部７１に取り付けられた変位センサ９１と、第２の摺動部７５に取り付けられた板状の検出板９２とを有している。変位センサ９１と検出板９２とは、第１の摺動部７１および第２の摺動部７５の摺動方向において対向している。検出板９２は、平滑板であり、第１の摺動部７１および第２の摺動部７５の摺動方向に直交して広がっている。第１の摺動部７１と第２の摺動部７５とは、第１のローラ５１の変位量と第２のローラ６１の変位量との差に応じて、摺動量に差が生じることになり、よって、変位センサ９１と検出板９２とが、第１のローラ５１の変位量と第２のローラ６１の変位量との差に応じた間隔をあけることになる。 As shown in FIGS. 3 and 4, the measuring unit 25 has a displacement sensor 91 attached to the first sliding portion 71 and a plate-shaped detection plate 92 attached to the second sliding portion 75. Have. The displacement sensor 91 and the detection plate 92 face each other in the sliding direction of the first sliding portion 71 and the second sliding portion 75. The detection plate 92 is a smooth plate, and spreads orthogonally to the sliding direction of the first sliding portion 71 and the second sliding portion 75. The sliding amount of the first sliding portion 71 and the second sliding portion 75 is different depending on the difference between the displacement amount of the first roller 51 and the displacement amount of the second roller 61. Therefore, the displacement sensor 91 and the detection plate 92 are spaced apart according to the difference between the displacement amount of the first roller 51 and the displacement amount of the second roller 61.

検査装置１０は、図１に示す第１の検出部２３の第１のローラ５１と第２の検出部２４の第２のローラ６１とを前進させて有孔部材の内周面に当接させた状態で、回転軸１１および検出ユニット１２を回転させることになり、測定部２５は、その際に生じる第１の揺動部２１の一端の第１の検出部２３側および第２の揺動部２２の一端の第２の検出部２４側の変位を、支点である支持軸３３を中心として生じる第１の揺動部２１および図２に示す第２の揺動部２２の他端側の変位で測定する。つまり、測定部２５は、第１の検出部２３および第２の検出部２４で検出した変位を測定する。その際に、測定部２５は、第１の揺動部２１の他端側である上端側と第２の揺動部２２の他端側である上端側との相対変位を測定する。なお、図１に示す第１のローラ５１と第２のローラ６１とを有孔部材の内周面に当接させた状態で、停止状態にある検出ユニット１２に対し、有孔部材を回転させても良い。つまり、検査装置１０は、第１のローラ５１と第２のローラ６１とを有孔部材の内周面に当接させた状態で、検出ユニット１２に対して有孔部材を相対回転させて検査を行う。 The inspection device 10 advances the first roller 51 of the first detection unit 23 and the second roller 61 of the second detection unit 24 shown in FIG. 1 to bring them into contact with the inner peripheral surface of the perforated member. In this state, the rotating shaft 11 and the detection unit 12 are rotated, and the measuring unit 25 causes the first detecting unit 23 side and the second shaking of one end of the first shaking unit 21 generated at that time. The displacement of one end of the portion 22 on the second detection portion 24 side is caused by the displacement of the support shaft 33 as a fulcrum on the other end side of the first rocking portion 21 and the second rocking portion 22 shown in FIG. Measure by displacement. That is, the measuring unit 25 measures the displacement detected by the first detecting unit 23 and the second detecting unit 24. At that time, the measuring unit 25 measures the relative displacement between the upper end side, which is the other end side of the first rocking portion 21, and the upper end side, which is the other end side of the second rocking portion 22. In a state where the first roller 51 and the second roller 61 shown in FIG. 1 are in contact with the inner peripheral surface of the perforated member, the perforated member is rotated with respect to the detection unit 12 in the stopped state. You may. That is, the inspection device 10 inspects the perforated member by rotating the perforated member relative to the detection unit 12 in a state where the first roller 51 and the second roller 61 are in contact with the inner peripheral surface of the perforated member. I do.

検査装置１０は、具体的には、図５に示すディスクブレーキ１１１の組み立て工程で使用される。ディスクブレーキ１１１は、自動車等の車両用のもの、具体的には四輪自動車用のもので、キャリア１１２と、一対のパッド１１３と、キャリパ１１４とを備えている。ディスクブレーキ１１１は、制動対象となる図示略の車輪と共に回転するディスク１１５の回転を止めて車両を制動する。 Specifically, the inspection device 10 is used in the assembly process of the disc brake 111 shown in FIG. The disc brake 111 is for a vehicle such as an automobile, specifically for a four-wheeled automobile, and includes a carrier 112, a pair of pads 113, and a caliper 114. The disc brake 111 brakes the vehicle by stopping the rotation of the disc 115, which rotates together with the wheels (not shown) to be braked.

キャリア１１２は、ディスク１１５の外径側を跨ぐように配置されて車両の非回転部に固定される。一対のパッド１１３は、ディスク１１５の両面に対向配置された状態でディスク１１５の軸方向に移動可能となるようにキャリア１１２に支持される。キャリパ１１４は、ディスク１１５の外径側を跨いだ状態でディスク１１５の軸方向に摺動可能となるようにキャリア１１２に支持される。 The carrier 112 is arranged so as to straddle the outer diameter side of the disc 115 and is fixed to the non-rotating portion of the vehicle. The pair of pads 113 are supported by the carrier 112 so as to be movable in the axial direction of the disc 115 while being arranged to face each other on both sides of the disc 115. The caliper 114 is supported by the carrier 112 so as to be slidable in the axial direction of the disc 115 while straddling the outer diameter side of the disc 115.

キャリパ１１４は、一対のパッド１１３をディスク１１５に押圧することによりディスク１１５の回転を止めるものであり、ディスク１１５を跨いだ状態でキャリア１１２に支持されるキャリパボディ１２０と、キャリパボディ１２０内に保持されてディスク１１５の一面側に対向するように配置されるピストン１２１とを有している。 The caliper 114 stops the rotation of the disc 115 by pressing a pair of pads 113 against the disc 115, and is held in the caliper body 120 supported by the carrier 112 while straddling the disc 115 and in the caliper body 120. It has a piston 121 that is arranged so as to face one side of the disc 115.

キャリパボディ１２０は、ブレーキ液圧が付与されるシリンダ１２５と、ディスク１１５を跨ぐブリッジ部１２６と、一対のパッド１１３のうちのアウタ側（車幅方向外側）のパッド１１３を押圧する爪部１２７とを有して一体的に構成されている。 The caliper body 120 includes a cylinder 125 to which brake fluid pressure is applied, a bridge portion 126 straddling the disc 115, and a claw portion 127 for pressing the pad 113 on the outer side (outside in the vehicle width direction) of the pair of pads 113. It is integrally configured with.

シリンダ１２５は、ディスク１１５の軸方向のインナ側（車幅方向内側）の面に対向配置されており、ディスク１１５側に開口する筒状のシリンダ側壁部１３１と、シリンダ側壁部１３１のディスク１１５とは反対側を閉塞するシリンダ底部１３２とを有する有底筒状をなしている。シリンダ１２５は、これらシリンダ側壁部１３１およびシリンダ底部１３２の内側がボア穴１３３となっており、ボア穴１３３はディスク１１５側に開口してディスク１１５の軸方向に沿っている。ピストン１２１は、ボア穴１３３の一定径の摺動内径部１３４内に摺動可能に挿入されている。ブリッジ部１２６は、ディスク１１５を跨ぐためにシリンダ１２５からディスク１１５の軸方向へ延びて形成されている。爪部１２７は、ブリッジ部１２６のシリンダ１２５とは反対側の端部からシリンダ１２５と対向するように延出しており、ディスク１１５のアウタ側の面に対向配置されている。 The cylinder 125 is arranged to face the inner side (inside in the vehicle width direction) surface of the disc 115 in the axial direction, and has a cylindrical cylinder side wall 131 that opens to the disc 115 side and a disc 115 of the cylinder side wall 131. Has a bottomed tubular shape having a cylinder bottom 132 that closes the opposite side. The cylinder 125 has a bore hole 133 inside the cylinder side wall portion 131 and the cylinder bottom portion 132, and the bore hole 133 opens to the disk 115 side and runs along the axial direction of the disk 115. The piston 121 is slidably inserted into the sliding inner diameter portion 134 having a constant diameter in the bore hole 133. The bridge portion 126 is formed so as to extend from the cylinder 125 in the axial direction of the disc 115 so as to straddle the disc 115. The claw portion 127 extends from the end portion of the bridge portion 126 opposite to the cylinder 125 so as to face the cylinder 125, and is arranged so as to face the outer surface of the disc 115.

キャリパ１１４は、ボア穴１３３内に導入されるブレーキ液圧によりピストン１２１をディスク１１５側に前進させる。すると、ピストン１２１はディスク軸方向に沿って移動し、インナ側のパッド１１３をディスク１１５に押圧する。このピストン１２１の押圧反力で、キャリパボディ１２０は、キャリア１１２に対してシリンダ１２５をディスク１１５から離す方向に移動し、爪部１２７でアウタ側のパッド１１３をディスク１１５に押圧する。このようにして、ピストン１２１と爪部１２７とで両側のパッド１１３を挟持しディスク１１５に押圧して摩擦抵抗を発生させ、制動力を発生させる。 The caliper 114 advances the piston 121 toward the disc 115 by the brake fluid pressure introduced into the bore hole 133. Then, the piston 121 moves along the disc axial direction and presses the pad 113 on the inner side against the disc 115. The pressing reaction force of the piston 121 causes the caliper body 120 to move the cylinder 125 with respect to the carrier 112 in a direction away from the disc 115, and the claw portion 127 presses the pad 113 on the outer side against the disc 115. In this way, the pads 113 on both sides are sandwiched between the piston 121 and the claw portion 127 and pressed against the disc 115 to generate frictional resistance and generate braking force.

なお、ボア穴１３３を形成するシリンダ側壁部１３１の内周面の軸方向における開口側の中間位置には、摺動内径部１３４よりも径方向外方に凹む円環状のシール溝１３７が形成されている。シリンダ側壁部１３１の内周面のシール溝１３７よりも開口側には、摺動内径部１３４よりも径方向外方に凹む円環状のブーツ溝１３８が形成されている。シール溝１３７には、ピストン１２１とシリンダ１２５との隙間をシールする円環状のオイルシールであるピストンシール１３９が嵌合されている。ブーツ溝１３８には、ピストン１２１との間に介装される円環状のブーツ１４０の一端が嵌合されている。爪部１２７には、ボア穴１３３を加工するための工具が挿入されるリセス１４１が形成されている。リセス１４１は、爪部１２７のディスク周方向の中間位置にディスク径方向の内側から外側に向けて凹状をなすように形成されている。 An annular seal groove 137 that is concave outward in the radial direction from the sliding inner diameter portion 134 is formed at an intermediate position on the opening side of the inner peripheral surface of the cylinder side wall portion 131 forming the bore hole 133 in the axial direction. ing. An annular boot groove 138 that is concave outward in the radial direction from the sliding inner diameter portion 134 is formed on the opening side of the inner peripheral surface of the cylinder side wall portion 131 with respect to the seal groove 137. A piston seal 139, which is an annular oil seal that seals the gap between the piston 121 and the cylinder 125, is fitted in the seal groove 137. One end of the annular boot 140 interposed between the boot groove 138 and the piston 121 is fitted in the boot groove 138. A recess 141 into which a tool for machining a bore hole 133 is inserted is formed in the claw portion 127. The recess 141 is formed so as to form a concave shape from the inside to the outside in the disc radial direction at an intermediate position of the claw portion 127 in the disc circumferential direction.

上記した検査装置１０は、図６に示すように金属製のキャリパボディ１２０のシール溝１３７にゴム製のピストンシール１３９が取り付けられた状態の有孔部材である中間組立体１５１の内周面を検査する。検査装置１０は、キャリパボディ１２０のシール溝１３７にピストンシール１３９が適正に取り付けられているか否かを検査する。ここで、シール溝１３７は溝底面がシリンダ底部１３２側ほど小径となるテーパ面となっており、シール溝１３７に適正に取り付けられた状態のピストンシール１３９も内周面がシリンダ底部１３２側ほど小径となるテーパ面となる。第２のローラ６１の外周面がこの内周面に合わせた角度のテーパ面となっている。また、キャリパボディ１２０のボア穴１３３の摺動内径部１３４の内周面は円筒面であり、第１のローラ５１の外周面がこの内周面に合わせて円筒面となっている。 As shown in FIG. 6, the inspection device 10 described above covers the inner peripheral surface of the intermediate assembly 151, which is a perforated member in which the rubber piston seal 139 is attached to the seal groove 137 of the metal caliper body 120. inspect. The inspection device 10 inspects whether or not the piston seal 139 is properly attached to the seal groove 137 of the caliper body 120. Here, the seal groove 137 has a tapered surface whose bottom surface has a smaller diameter toward the cylinder bottom 132 side, and the inner peripheral surface of the piston seal 139 properly attached to the seal groove 137 also has a smaller diameter toward the cylinder bottom 132 side. It becomes a tapered surface. The outer peripheral surface of the second roller 61 is a tapered surface having an angle adjusted to the inner peripheral surface. Further, the inner peripheral surface of the sliding inner diameter portion 134 of the bore hole 133 of the caliper body 120 is a cylindrical surface, and the outer peripheral surface of the first roller 51 is a cylindrical surface in accordance with the inner peripheral surface.

例えば、キャリパボディ１２０へのピストンシール１３９の自動機による組み付け工程後に、ロボット又は作業者により中間組立体１５１が検査装置１０にセットされる。中間組立体１５１はそのキャリパボディ１２０が爪部１２７を上側にシリンダ底部１３２を下側にして検査装置１０にセットされる。このセット後、検査装置１０は、図７に示す流れの検査工程を行って中間組立体１５１を検査する。 For example, after the step of assembling the piston seal 139 to the caliper body 120 by an automatic machine, the intermediate assembly 151 is set in the inspection device 10 by a robot or an operator. The caliper body 120 of the intermediate assembly 151 is set in the inspection device 10 with the claw portion 127 on the upper side and the cylinder bottom portion 132 on the lower side. After this setting, the inspection device 10 inspects the intermediate assembly 151 by performing the flow inspection step shown in FIG. 7.

すなわち、まず、検出軸６８を、爪部１２７のリセス１４１を介してボア穴１３３およびピストンシール１３９の内側に挿入する検出軸ボア内挿入工程Ｓ１を行う。このとき、キャリパボディ１２０のボア穴１３３の摺動内径部１３４の内周面と、ピストンシール１３９の内周面とが中間組立体１５１の内周面となる。検出軸ボア内挿入工程後の状態で、検出軸６８は、第１の検出部２３の第１のローラ５１が、キャリパボディ１２０のボア穴１３３のシール溝１３７よりもシリンダ底部１３２側の摺動内径部１３４の内周面に高さを合わせることになり、第２の検出部２４の第２のローラ６１が、ピストンシール１３９の内周面に高さを合わせることになる。 That is, first, the detection shaft bore insertion step S1 is performed in which the detection shaft 68 is inserted into the bore hole 133 and the piston seal 139 through the recess 141 of the claw portion 127. At this time, the inner peripheral surface of the sliding inner diameter portion 134 of the bore hole 133 of the caliper body 120 and the inner peripheral surface of the piston seal 139 serve as the inner peripheral surface of the intermediate assembly 151. In the state after the insertion step in the detection shaft bore, the first roller 51 of the first detection unit 23 slides on the cylinder bottom 132 side of the seal groove 137 of the bore hole 133 of the caliper body 120. The height is adjusted to the inner peripheral surface of the inner diameter portion 134, and the second roller 61 of the second detection unit 24 is adjusted to the inner peripheral surface of the piston seal 139.

この状態で、検査装置１０は、駆動シリンダ８２を後退状態にするローラ前進工程Ｓ２を行う。つまり、駆動シリンダ８２の移動部材８１が金属カラー部材８５およびスプリング部材８６を介して、第１の摺動部７１および第２の摺動部７５を手前に移動させる。すると、第１の上部ピン４２および図示略の第２の上部ピンが駆動シリンダ８２側に移動し、第１の揺動部２１および第２の揺動部２２が支持軸３３を中心に揺動して第１の下部ピン４１および第２の下部ピン４５を第１の上部ピン４２および図示略の第２の上部ピンとは逆方向に移動させる。その結果、第１の検出部２３は第１のローラ５１が前進して、キャリパボディ１２０の摺動内径部１３４の内周面に当接し、第２の検出部２４は第２のローラ６１が前進して、ピストンシール１３９の内周面に当接する。 In this state, the inspection device 10 performs the roller advancing step S2 for moving the drive cylinder 82 into the retracted state. That is, the moving member 81 of the drive cylinder 82 moves the first sliding portion 71 and the second sliding portion 75 toward the front via the metal collar member 85 and the spring member 86. Then, the first upper pin 42 and the second upper pin (not shown) move toward the drive cylinder 82, and the first swing portion 21 and the second swing portion 22 swing around the support shaft 33. Then, the first lower pin 41 and the second lower pin 45 are moved in the directions opposite to those of the first upper pin 42 and the second upper pin (not shown). As a result, the first roller 51 advances in the first detection unit 23 and comes into contact with the inner peripheral surface of the sliding inner diameter portion 134 of the caliper body 120, and the second roller 61 in the second detection unit 24 It advances and comes into contact with the inner peripheral surface of the piston seal 139.

次に、検査装置１０は、測定部２５の変位センサ９１で変位センサ９１と検出板９２との間の距離の測定を開始する測定開始工程Ｓ３を行い、回転軸１１および検出ユニット１２を３６０°以上の所定の角度回転させる検出軸旋回工程Ｓ４を行う。 Next, the inspection device 10 performs the measurement start step S3 for starting the measurement of the distance between the displacement sensor 91 and the detection plate 92 by the displacement sensor 91 of the measuring unit 25, and makes the rotating shaft 11 and the detection unit 12 360 °. The detection shaft turning step S4 for rotating the above predetermined angle is performed.

次に、検査装置１０は、駆動シリンダ８２を待機状態にするローラ後退工程Ｓ５を行う。つまり、駆動シリンダ８２が金属カラー部材８５およびスプリング部材８６を介して、第１の摺動部７１および第２の摺動部７５を待機位置に戻す。すると、第１の上部ピン４２および図示略の第２の上部ピンが駆動シリンダ８２とは反対側に移動し、第１の揺動部２１および第２の揺動部２２が支持軸３３を中心に揺動して第１の下部ピン４１および第２の下部ピン４５を第１の上部ピン４２および図示略の第２の上部ピンとは逆方向に移動させる。その結果、第１の検出部２３は第１のローラ５１が後退して待機位置に戻り、第２の検出部２４は第２のローラ６１が後退して待機位置に戻る。 Next, the inspection device 10 performs a roller retreat step S5 that puts the drive cylinder 82 in the standby state. That is, the drive cylinder 82 returns the first sliding portion 71 and the second sliding portion 75 to the standby position via the metal collar member 85 and the spring member 86. Then, the first upper pin 42 and the second upper pin (not shown) move to the side opposite to the drive cylinder 82, and the first swing portion 21 and the second swing portion 22 are centered on the support shaft 33. The first lower pin 41 and the second lower pin 45 are moved in the opposite directions to the first upper pin 42 and the second upper pin (not shown). As a result, in the first detection unit 23, the first roller 51 retracts and returns to the standby position, and in the second detection unit 24, the second roller 61 retracts and returns to the standby position.

次に、検査装置１０は、上記検出軸旋回工程Ｓ４での測定部２５の変位センサ９１での検出結果に基づいて中間組立体１５１の内周面が正常であるか否かを判定する判定工程Ｓ６を行う。つまり、キャリパボディ１２０のシール溝１３７にピストンシール１３９が組み付けられていなかったり、キャリパボディ１２０のシール溝１３７からピストンシール１３９が一部外れていたり、シール溝１３７内でピストンシール１３９が捻れていたりすると、キャリパボディ１２０のシール溝１３７にピストンシール１３９が正常に組み付けられている場合と比べて、検出軸６８の回転中に、一定径の摺動内径部１３４の内周面に当接する第１のローラ５１と、ピストンシール１３９に当接する第２のローラ６１との相対位置のずれ量が大きくなる状態が生じる。その結果、変位センサ９１と検出板９２との距離が所定の許容範囲を超えることになる。 Next, the inspection device 10 determines whether or not the inner peripheral surface of the intermediate assembly 151 is normal based on the detection result of the displacement sensor 91 of the measuring unit 25 in the detection shaft turning step S4. Perform S6. That is, the piston seal 139 is not assembled in the seal groove 137 of the caliper body 120, the piston seal 139 is partially removed from the seal groove 137 of the caliper body 120, or the piston seal 139 is twisted in the seal groove 137. Then, as compared with the case where the piston seal 139 is normally assembled in the seal groove 137 of the caliper body 120, the first contact with the inner peripheral surface of the sliding inner diameter portion 134 having a constant diameter during the rotation of the detection shaft 68. A state occurs in which the amount of displacement between the roller 51 and the second roller 61 in contact with the piston seal 139 becomes large. As a result, the distance between the displacement sensor 91 and the detection plate 92 exceeds a predetermined allowable range.

このように、検出軸旋回工程Ｓ４中に、変位センサ９１と検出板９２との距離が所定の許容範囲を超える状態が発生すると、検査装置１０は、キャリパボディ１２０のシール溝１３７にピストンシール１３９が組み付けられていなかったり、キャリパボディ１２０のシール溝１３７からピストンシール１３９が一部外れていたり、シール溝１３７内でピストンシール１３９が捻れたりする組み付け不良が生じていたと、判定工程Ｓ６において判定し、ピストンシール１３９の組み付け不良を報知する。 As described above, when the distance between the displacement sensor 91 and the detection plate 92 exceeds a predetermined allowable range during the detection shaft turning step S4, the inspection device 10 puts the piston seal 139 in the seal groove 137 of the caliper body 120. In the determination step S6, it is determined that the piston seal 139 is partially disengaged from the seal groove 137 of the caliper body 120, or the piston seal 139 is twisted in the seal groove 137. , Notifies the assembly failure of the piston seal 139.

検出軸旋回工程Ｓ４の全体において、変位センサ９１と検出板９２との距離が所定の許容範囲内にあると、検査装置１０は、キャリパボディ１２０のシール溝１３７にピストンシール１３９が正常に組み付けられていると判定し、ピストンシール１３９の組み付けが正常であることを報知する。すると、ロボット又は作業者が中間組立体１５１を検査装置１０から取り外して次工程の装置にセットする。 When the distance between the displacement sensor 91 and the detection plate 92 is within a predetermined allowable range in the entire detection shaft turning step S4, the inspection device 10 normally assembles the piston seal 139 into the seal groove 137 of the caliper body 120. It is determined that the piston seal 139 is assembled normally. Then, the robot or the operator removes the intermediate assembly 151 from the inspection device 10 and sets it in the device of the next process.

特許文献１には、有孔部材の内周面を検査する装置が記載されている。この装置は、内径側に溝等の凹部を成型した各種部品における切削屑等の異物の残存や、溝内底面の変形の存在を検査するものである。この装置は、一端側に測定子が付いた測定軸を他端側で支持し、測定子を有孔部材の内周面に当接させた状態で、この他端側よりも一端側に配置された円盤の変位をセンサ部で検出するようになっている。このため、測定軸が、測定子を有孔部材の内周面に押し付ける際の反力で変形する可能性があり、この反力に対する剛性を確保しなければ、検出精度に影響を及ぼす可能性がある。このため、所定の検出精度を保つためにメンテナンスの頻度を増やさざるを得なくなってしまう。 Patent Document 1 describes an apparatus for inspecting the inner peripheral surface of a perforated member. This device inspects the residual foreign matter such as cutting chips and the presence of deformation of the inner bottom surface of the groove in various parts formed with a recess such as a groove on the inner diameter side. This device supports a measuring shaft with a stylus on one end side on the other end side, and the stylus is placed on one end side of the other end side in a state where the stylus is in contact with the inner peripheral surface of the perforated member. The displacement of the disk is detected by the sensor unit. Therefore, the measuring shaft may be deformed by the reaction force when the stylus is pressed against the inner peripheral surface of the perforated member, and if the rigidity against this reaction force is not secured, the detection accuracy may be affected. There is. Therefore, the frequency of maintenance has to be increased in order to maintain a predetermined detection accuracy.

これに対して、実施形態の検査装置１０は、第１の検出部２３が一端側に設けられると共に該一端側と他端側との間の領域に支点である支持軸３３を有してベース部２０に揺動可能に支持される第１の揺動部２１と、第２の検出部２４が一端側に設けられると共に該一端側と他端側との間の領域に支点である支持軸３３を有してベース部２０に揺動可能に支持される第２の揺動部２２とを有しており、測定部２５は、第１の揺動部２１および第２の揺動部２２の他端側近傍で、第１の検出部２３および第２の検出部２４を当接させた状態で中間組立体１５１を相対回転させた際に生じる第１の揺動部２１および第２の揺動部２２の一端側の変位を、支点である支持軸３３を中心として生じる第１の揺動部２１および第２の揺動部２２の他端側の変位で測定する。このように、中間組立体１５１から受ける反力で第１の揺動部２１および第２の揺動部２２が揺動する構造であるため、反力を受けても変形しにくくなる。したがって、有孔部材である中間組立体１５１の内周面を精度良く検査することができる。しかも、反力に対する剛性不足になりにくい構造であるため、メンテナンスの頻度を減らすことができる。 On the other hand, the inspection device 10 of the embodiment has a base in which the first detection unit 23 is provided on one end side and has a support shaft 33 as a fulcrum in the region between the one end side and the other end side. A first swinging portion 21 swingably supported by the portion 20 and a second detecting portion 24 are provided on one end side, and a support shaft serving as a fulcrum in a region between the one end side and the other end side. It has a second rocking portion 22 having 33 and being swingably supported by the base portion 20, and the measuring unit 25 has a first rocking portion 21 and a second rocking portion 22. The first rocking portion 21 and the second swinging portion 21 generated when the intermediate assembly 151 is relatively rotated in a state where the first detecting portion 23 and the second detecting portion 24 are in contact with each other in the vicinity of the other end side of the above. The displacement of one end side of the swinging portion 22 is measured by the displacement of the other end side of the first swinging portion 21 and the second swinging portion 22 generated around the support shaft 33 which is a fulcrum. As described above, since the structure is such that the first rocking portion 21 and the second swinging portion 22 swing by the reaction force received from the intermediate assembly 151, the deformation is less likely to occur even if the reaction force is received. Therefore, the inner peripheral surface of the intermediate assembly 151, which is a perforated member, can be inspected with high accuracy. Moreover, since the structure is such that the rigidity against the reaction force is not insufficient, the frequency of maintenance can be reduced.

また、検査装置１０は、第１のローラ５１が一端側に設けられる第１の揺動部２１と、第２のローラ６１が一端側に設けられる第２の揺動部２２とを有し、測定部２５が、第１の揺動部２１の他端側と第２の揺動部２２の他端側との相対変位を測定するため、測定の基準となる摺動内径部１３４に第１のローラ５１を直接当接させ、検査対象のピストンシール１３９に第２のローラ６１を直接当接させて測定することになる。よって、摺動内径部１３４およびピストンシール１３９の両方を同じ条件で測定することができ、検出をより安定させることができる。 Further, the inspection device 10 has a first swinging portion 21 in which the first roller 51 is provided on one end side, and a second swinging portion 22 in which the second roller 61 is provided on one end side. Since the measuring unit 25 measures the relative displacement between the other end side of the first rocking portion 21 and the other end side of the second rocking portion 22, the first sliding inner diameter portion 134, which is a reference for measurement, is used. The second roller 61 is brought into direct contact with the piston seal 139 to be inspected, and the measurement is performed. Therefore, both the sliding inner diameter portion 134 and the piston seal 139 can be measured under the same conditions, and the detection can be made more stable.

また、検査装置１０は、摺動内径部１３４用の第１のローラ５１を含む第１の検出部２３の移動量を第１の揺動部２１を介して第１の摺動部７１および変位センサ９１に伝達し、ピストンシール１３９用の第２のローラ６１を含む第２の検出部２４の移動量を第２の揺動部２２を介して第２の摺動部７５および検出板９２に伝達するため、それぞれ独立した伝達系統で移動量を伝達することができる。よって、第１のローラ５１および第２のローラ６１の一方が受けた変位の影響を他方に及ぼすことなく検出することが可能となる。 Further, the inspection device 10 displaces the movement amount of the first detection unit 23 including the first roller 51 for the sliding inner diameter portion 134 with the first sliding portion 71 via the first rocking portion 21. It is transmitted to the sensor 91, and the amount of movement of the second detection unit 24 including the second roller 61 for the piston seal 139 is transmitted to the second sliding portion 75 and the detection plate 92 via the second rocking portion 22. Since it is transmitted, the amount of movement can be transmitted by each independent transmission system. Therefore, it is possible to detect the influence of the displacement received by one of the first roller 51 and the second roller 61 without affecting the other.

また、検査装置１０は、第１の検出部２３が、中間組立体１５１の内周面に当接する第１のローラ５１と、第１のローラ５１をベース部２０に対して直線移動可能に連結する第１の下部ガイド部５３とを備えており、第２の検出部２４が、中間組立体１５１の内周面に当接する第２のローラ６１と、第２のローラ６１をベース部２０に対して直線移動可能に連結する第２の下部ガイド部６３とを備えている。よって、有孔部材である中間組立体１５１の内周面をより精度良く検査することができる。 Further, in the inspection device 10, the first detection unit 23 connects the first roller 51 that abuts on the inner peripheral surface of the intermediate assembly 151 and the first roller 51 so as to be linearly movable with respect to the base portion 20. A second lower guide portion 53 is provided, and the second detection portion 24 attaches the second roller 61 that abuts to the inner peripheral surface of the intermediate assembly 151 and the second roller 61 to the base portion 20. It is provided with a second lower guide portion 63 that is connected so as to be linearly movable. Therefore, the inner peripheral surface of the intermediate assembly 151, which is a perforated member, can be inspected more accurately.

また、検査装置１０は、変位センサ９１を含む測定部２５をボア穴１３３の外部に配置することにより、検出軸６８をスリムにすることができる。よって、中間組立体１５１のリセス１４１が小さかったり、中間組立体１５１のボア穴１３３が小径であっても、良好に検査することができる。 Further, the inspection device 10 can make the detection shaft 68 slim by arranging the measurement unit 25 including the displacement sensor 91 outside the bore hole 133. Therefore, even if the recess 141 of the intermediate assembly 151 is small or the bore hole 133 of the intermediate assembly 151 has a small diameter, good inspection can be performed.

また、検査装置１０は、変位センサ９１が、平滑な検出板９２との間の距離を検出するため、キャリパボディ１２０の内周面との間の距離を検出する場合と比べて、素材違いの影響を受けにくくなる。よって、例えば鋳鉄製とアルミニウム鋳物製のキャリパボディ１２０が混在する組み立てラインに設置しても、良好に検査を行うことができる。 Further, in the inspection device 10, since the displacement sensor 91 detects the distance between the smooth detection plate 92 and the smooth detection plate 92, the material is different from the case where the displacement sensor 91 detects the distance between the caliper body 120 and the inner peripheral surface. Less susceptible. Therefore, for example, even if the caliper body 120 made of cast iron and cast aluminum is installed in a mixed assembly line, good inspection can be performed.

また、検査装置１０は、第１の検出部２３、第２の検出部２４、第１の摺動部７１および第２の摺動部７５を、いずれもリニアガイドである第１の下部ガイド部５３、第２の下部ガイド部６３、第１の上部ガイド部７２および第２の上部ガイド部７６によって動作軸方向に移動させるため、これらの支持剛性が上がる。よって、メンテナンスの頻度をさらに減らすことができる。 Further, the inspection device 10 has a first lower guide portion that is a linear guide for the first detection unit 23, the second detection unit 24, the first sliding portion 71, and the second sliding portion 75. Since the 53, the second lower guide portion 63, the first upper guide portion 72, and the second upper guide portion 76 move in the operation axis direction, their support rigidity is increased. Therefore, the frequency of maintenance can be further reduced.

以上に述べた実施形態の第１の態様は、有孔部材の内周面に当接する検出部と、該検出部で検出した変位を測定する測定部とを備えて前記有孔部材の内周面を検査する検査装置において、前記検出部が一端側に設けられると共に該一端側と他端側との間の領域に支点を有してベース部に揺動可能に支持される揺動部を有し、前記測定部は、前記揺動部の前記他端側近傍に配置されるとともに、前記検出部を当接させた状態で前記有孔部材を相対回転させた際に生じる前記揺動部の前記一端側の変位を、前記支点を中心として生じる前記揺動部の前記他端側の変位で測定する。このように有孔部材から受ける反力で揺動部が揺動する構造であるため、反力で変形しにくくなる。したがって、有孔部材の内周面を精度良く検査することができる。 In the first aspect of the embodiment described above, the inner circumference of the perforated member is provided with a detection unit that abuts on the inner peripheral surface of the perforated member and a measuring unit that measures the displacement detected by the detection unit. In an inspection device for inspecting a surface, a swinging portion that is provided on one end side and has a fulcrum in a region between the one end side and the other end side and is swingably supported by a base portion. The measuring portion is arranged in the vicinity of the other end side of the swinging portion, and the swinging portion generated when the perforated member is relatively rotated with the detecting portion in contact with the measuring portion. The displacement on the one end side of the above is measured by the displacement on the other end side of the swinging portion generated around the fulcrum. Since the swinging portion swings due to the reaction force received from the perforated member in this way, it is difficult to deform due to the reaction force. Therefore, the inner peripheral surface of the perforated member can be inspected with high accuracy.

The first roller has a first swinging portion provided on the one end side, and the second roller has a second swinging portion provided on the one end side, and the measuring portion is the first The relative displacement between the other end side of the rocking portion and the other end side of the second rocking portion is measured. Therefore, it is possible to measure two points on the inner peripheral surface of the perforated member under the same conditions, and the detection can be made more stable.

第３の態様は、第１または第２の態様において、前記検出部は、前記有孔部材の内周面に当接するローラと、該ローラをベース部に対して直線移動可能に連結するガイド部とを備える。よって、ローラの支持剛性が上がり、有孔部材の内周面をより精度良く検査することができる。 In a third aspect, in the first or second aspect, the detection unit is a guide portion that connects a roller that abuts on the inner peripheral surface of the perforated member and the roller so as to be linearly movable with respect to the base portion.
