Since the chain type tool magazine is vertically installed, in order to prevent the tool case from falling off the tool apron carelessly due to its own weight, most of the known chain type tool magazines including the above patent technologies have supporting plates at both sides of the periphery of the operation track, so as to limit all the tool apron and tool case and prevent the tool case from falling off. However, the installation of the support plate not only increases the volume of the chain type tool magazine, but also makes the maintenance inconvenient, and the support plate must have a notch at the corresponding tool-taking position to avoid the operation of tool changing, but the notch still causes the tool case in operation to drop from the position. Therefore, some manufacturers will add a spring clamp plate in each tool seat of the chain type tool magazine to clamp and squeeze the tool sleeve to improve the stability of the tool sleeve in the tool seat, but the spring clamp plate is hidden in this way, which leads to the problem that the tool sleeve cannot be firmly clamped and is loosened due to elastic fatigue, and the loosening tendency is more remarkable when the total weight of the tool sleeve, the tool bar inserted in the tool sleeve and the tool is heavier.

Detailed Description

To illustrate the present invention more clearly, a preferred embodiment is described in detail below with reference to the accompanying drawings. Referring to fig. 1 to 9, a chain type tool magazine 100 according to a preferred embodiment of the present invention is applied to a horizontal machining center, but not limited thereto. The chain type tool magazine 100 includes a rail 101 and a plurality of supporting bodies 10 pivotally connected to each other to form a chain capable of moving along the rail 101, each supporting body 10 is combined with a tool sleeve 20 capable of being separated therefrom, the tool sleeve 20 has a receiving hole 22 for receiving the tool bar 30 therein, and the tool sleeve 20 is fixed to the supporting body 10 before being unlocked by a locking unit 40 (see fig. 10 and 11). The chain magazine 100 is provided with an unlocking unit 50 and a knife conveying mechanism 60 at one side of the track 101 and corresponding to a knife taking position on the track 101, for convenience of description, the position of the knife case 20 centered on the position shown in fig. 1 is defined as a knife taking position, and the unlocking unit 50 is used for releasing the locking relationship of the locking unit 40 between the support 10 and the knife case 20 at the knife taking position, so that the knife case 20 can be separated from the support 10; the knife transport mechanism 60 is used to deliver the unlocked knife pouch 20 to a knife exchange mechanism (not shown).

The knife conveying mechanism 60 will be described after the specific combination relationship between the carrier 10 and the knife sheath 20 is described, and the locking and unlocking manner between the carrier and the knife sheath is described.

Referring to fig. 10 and 11, the carrier 10 includes a base 12 and two supporting members 14, the base 12 is located in the channel 101a of the rail 101 by a plurality of rollers 16 on the side surface thereof and can move along the rail 101 smoothly; the two supporting members 14 are round rods, one end of each supporting member is detachably fixed to the base 12, and the two supporting members 14 are suspended in parallel. The knife pouch 20 has two through holes 24, and the two through holes 24 are respectively located at two sides of the receiving hole 22 and are received in the corresponding supporting member 14, so that the knife pouch 20 can smoothly slide along the supporting member 14 without turning over. In the aforementioned knife pouch 20, the two circular through holes 24 are matched with the two supporting members 14, which are circular rod bodies, to achieve the purpose of sliding and matching without turning, however, in other embodiments, the supporting members may be polygonal rod bodies, and the through holes correspond to polygonal holes, so that the purpose of sliding and matching without turning the knife pouch can be achieved only by matching one supporting member with one through hole, but if the structural strength is considered, the knife pouch is still configured by matching two supporting members with two through holes. The base 12 of the carrier 10 has a first side hole 12a and a second side hole 12b which do not penetrate the base 12 and are orthogonal to each other; the sleeve 20 has a bore 26.

The locking unit 40 includes a fixing rod 41, a brake rod 42, an urging member 43, a restricting member 44 and a wear-resistant ring 45. Wherein, the fixing rod 41 comprises a shaft 41a and a head 41b connected with one end of the shaft 41a, the other end of the shaft 41a is inserted into the connecting hole 26, the head 41b is exposed outside the knife sheath 20, and a stop part 41c is formed at the connection part of the head 41b and the shaft 41 a; the shaft 41a of the fixing rod 41 may be provided with a screw thread and the connection hole 26 may be a screw hole to be detachably connected to the cutter holder to form a single body, but the fixing rod may be formed integrally with the cutter holder.

The brake lever 42, the pushing member 43, the limiting member 44 and the wear ring 45 are received in the second side hole 12b of the base 12. The brake lever 42 is capable of moving between a locking position PA shown in fig. 9 and an unlocking position PB shown in fig. 13, and includes a large diameter section 42a, a small diameter section 42b and a blocking wall 42c, the small diameter section 42b is located between the large diameter section 42a and the blocking wall 42c, the diameter of the large diameter section 42a is larger than that of the small diameter section 42b, and a joint of the large diameter section 42a and the small diameter section 42b forms a shoulder 42 d. The pushing member 43 provides a pushing force to the braking lever 42 to keep the braking lever 42 moving to the locking position PA, in this embodiment, the pushing member 43 is a spring, one end of the spring abuts against the bottom surface of the second side hole 12b, and the other end abuts against the braking lever 42, preferably, the braking lever 42 has a counter bore 42e for a part of the spring to extend into so that the spring does not deflect. The restricting member 44 is a C-shaped buckle and is engaged with the engaging groove 12C near the opening of the second side hole 12b, and is defined as being located at the locking position PA when the stop wall 42C of the brake lever 42 abuts against the restricting member 44. The wear-resistant ring 45 is made of a wear-resistant material and is sleeved between the outer peripheral surface of the large-diameter section 42a of the brake lever 42 and the hole wall of the second side hole 12b, so that the brake lever 42 can be prevented from directly contacting the hole wall of the second side hole 12b to cause wear.

As shown in fig. 5 and 8, the unlocking unit 50 includes a cylinder 52 and a top 54, the cylinder 52 is fixed on one side of the rail 101 and does not obstruct the movement of the chain, the cylinder 52 has a piston rod 52a capable of moving forward and backward by the pressure change inside the cylinder, one end of the piston rod 52a is connected to the top 54, and the top 54 has a pressing end 54a aligned with the brake lever 42 of the locking unit 40 at the knife-taking position. When the cylinder 52 is not actuated, the contact end 54a of the top 54 is spaced from the exposed end of the brake lever 42.

The above is a description of the coupling relationship between the carrier 10 and the holder 20, and the locking unit 40 and the unlocking unit 50. When the knife pouch 20 is coupled to the carrier 10, one end of the fixing rod 41 on the knife pouch 20 having the head 41b is inserted into the first side hole 12a of the base 12 of the corresponding carrier 10 (see fig. 7), and at the same time, the brake lever 42 is pushed by the pushing member 43 and is stopped at the locking position PA by the stopper 44, and in the above state, the abutting shoulder 42d of the brake lever 42 is just located on the path (see fig. 9) through which the fixing rod 41 is drawn out and abuts against the stopper 41c of the fixing rod 41, so that the fixing rod 41 cannot be drawn out from the first side hole 12a, and thus the knife pouch 20 integrally coupled to the fixing rod 41 can be stably coupled to the carrier 10 and change its position with the rotation of the chain. When the locking unit 40 is to be unlocked, the cylinder 52 is actuated to control the piston rod 52a to be pushed out, as shown in fig. 12 and 13, the pushing member 54 driven by the piston rod 52a pushes the braking lever 42 to move inward and move back to the unlocking position PB by the pressing end 54a thereof, so that the abutting shoulder 42d of the braking lever 42 exits from the path of the fixed lever 41 being pulled out (i.e. the abutting shoulder 42d no longer abuts against the stopping portion 41 c), and the braking lever 42 presses the pushing member 43, so as to separate the knife sheath 20 from the carrier 10, and the head 41b of the fixed lever 41 can pass through the small diameter section 42b of the braking lever 42 without hindrance and separate from the first side hole 12a, so that the knife sheath 20 can be separated from the carrier 10 along the supporting member 14.

The knife conveying mechanism 60 of the present embodiment will be described below. Referring to fig. 1 to 4 and 14 to 16, the knife conveying mechanism 60 includes a saddle 61, a knife sheath block 62, two guiding members 63, an actuating cylinder 64, a clamping unit 65 and two guide rods 66. The saddle 61 is in the shape of a long plate and is transversely fixed on a position on one side of the rail 101 where the movement of the chain is not hindered, the saddle 61 has a long opening 61a, and the unlocking unit 50 is fixed on the saddle 61. The tool holder block 62 is formed by connecting a first side block 62a and a second side block 62b, the first side block 62a is fixed at one end of the saddle 61, and the second side block 62b has an arc-shaped abutting surface 62 c. The two guiding members 63 are round rods with the same diameter as the supporting member 14, and one end of each guiding member 63 is detachably fixed to the first side block 62a and is suspended in parallel, and each guiding member 63 is located on the same axis with the corresponding supporting member 14, and it should be mentioned that a gap is kept between the guiding members 63 and the free end of the supporting member 14, and the gap ensures that the cutter sleeve 20 driven by the chain in operation does not collide with the guiding members 63. The actuating cylinder 64 includes a cylinder body 64a and a displacement member 64b, the cylinder body 64a is disposed on the back surface of the saddle 61, the displacement member 64b is a piston rod, one end of the displacement member 64b is disposed through the cylinder body 64a, and the other end of the displacement member is exposed outside the cylinder body 64a and is connected to a floating joint 64c, and by controlling the change of the internal pressure of the cylinder body 64a, the displacement member 64b can be driven to linearly reciprocate between a first position P1 retracted relative to the cylinder body 64a shown in fig. 3 and a second position P2 retracted relative to the cylinder body 64a shown in fig. 17.

The number of the above-mentioned guides 63 is two, and the purpose is also to allow the holder 20 to slide on the guides 63 without turning over. However, when the supporting member is a single polygonal rod and the through hole of the knife pouch is a polygonal hole, the guiding member is also a single polygonal rod, so that the sliding pair matching can be realized and the knife pouch can not be turned over.

In addition, a first fixing block 67 and a second fixing block 68 are fixedly arranged on the back of the saddle 61, at least one first stopper 69 is arranged on the first fixing block 67, and at least one second stopper 70 is arranged on the second fixing block 68; the first stop 69 and the second stop 70 can be adjusted to lock into the screw hole to change the position of the exposed head of the bolt.

The actuating cylinder 64 is connected to the clamping unit 65 by a floating joint 64c and can drive the clamping unit 65 to synchronously displace. The clamping unit 65 includes a first clamping block 651, a second clamping block 652, two fixing rods 653 and two springs 654. In order to make the first clamping block 651 and the second clamping block 652 move stably, in this embodiment, the two guide rods 66 are passed through the first clamping block 651 and the second clamping block 652 in a manner parallel to the axis passing through the supporting member 14 and the guiding member 63, and both ends of the guide rods 66 are respectively fixed on the first fixed block 67 and the second fixed block 68, so that the first clamping block 651 and the second clamping block 652 can slide along the guide rods 66 without turning over, and part of the first clamping block 651 and part of the second clamping block 652 pass through the elongated opening 61a of the saddle 61, where it is defined that the surfaces of the first clamping block 651 and the second clamping block 652, which face each other through the part of the elongated opening 61a, are respectively a first clamping surface 651a and a second clamping surface 652 a.

The two fixing rods 653 of the clamping unit 65 are parallel to the guide rods 66, and one end of each fixing rod 653 is fixedly connected to the first clamping block 651, and the other end of each fixing rod passes through the second clamping block 652 and is provided with a stopper 655 formed by a nut, so that the second clamping block 652 can move along the fixing rods 653 again. The two springs 654 are respectively sleeved on the corresponding fixing rods 653, and both ends of the two springs are respectively abutted against the stopper 655 and the second clamping block 652, because the stopper 655 is fixedly arranged on the fixing rod 653 and the fixing rod 653 is fixedly connected to the first clamping block 651, the springs 654 keep a state of pushing the second clamping block 652 to move towards the first clamping block 651 by using the stopper 655 as a fixed supporting point.

The number of the guide rods 66 is two, so as to prevent the first clamping block 651 and the second clamping block 652 from being turned over; the number of the fixing rods 653 and the springs 654 is two, so as to improve the stability between the first clamping block 651 and the second clamping block 652. However, the number of the guide rod 66, the fixing rod 653 and the spring 654 is not limited to the above-mentioned number, and for example, when the radial cross section of the shaft of the guide rod and the fixing rod is non-circular, the function can be realized by one number in practice.

The above is a structural description of the chain magazine 100 according to the preferred embodiment of the present invention, and the operation thereof will be described later.

As shown in fig. 8 and 9, the carrier 10 and the knife sheath 20 are kept in an inseparable state by the locking unit 40 under normal conditions, and due to the locking relationship of the locking unit 40, the knife sheath 20 rotating along with the chain does not fall off or fall off in a hidden manner as in the prior art. At the same time, the top 54 of the unlocking unit 50 is spaced from the brake lever 42 on the carrier 10, and the displacement member 64b of the actuating cylinder 64 of the knife transporting mechanism 60 stays at the first position P1, and in this state, the space between the first clamping face 651a of the first clamping block 651 and the second clamping face 652a of the second clamping block 652 is just passed by the knife holder 20 on the chain (see fig. 4), so that smooth operation of the chain is ensured, and the spring 654 is in a compressed state.

When the machining center is about to perform a tool changing procedure, the unlocking unit 50 is controlled to drive the pushing member 54 to push the braking lever 42 of the locking unit 40 to move back inwards to the unlocking position PB, as shown in fig. 12 and 13, so that the fixing rod 41 combined with the tool sheath 20 and the braking lever 42 hidden in the supporting body 10 do not interfere with each other. As shown in fig. 17 to fig. 19, the cylinder 64 of the knife transporting mechanism 60 is actuated to drive the displacement member 64b to leave the first position P1, and as the displacement member 64b gradually extends out of the cylinder 64a, the spring 654 releases the compressed energy storage, so that the first clamping block 651 is close to the second clamping block 652, and the knife sheath 20 which is located at the knife taking position and has been unlocked is clamped by the first clamping surface 651a and the second clamping surface 652a, and simultaneously, because one end of the spring 654 abuts against the stop 655 and the other end thereof abuts against the second clamping block 652, the first clamping block 651 and the second clamping block 652 can stably clamp the knife sheath 20. It should be noted that when the top member 54 of the unlocking unit 50 is rotated and retracted after the clamping unit 65 clamps and removes the knife pouch 20, the brake lever 42 is retracted to the locking position PA by the action of the pushing member 43 releasing the compressed energy.

During the process of the displacement member 64b continuing to move to the second position P2, the knife sheath 20 first follows the support member 14 and then slides into the guiding member 63, and when the first clamping block 651 abuts against the second blocking member 70, the knife sheath 20 abuts against the arc-shaped abutting surface 62c, and the knife sheath 20 is completely separated from the support member 14, which defines that the displacement member 64b is located at the second position P2. Therefore, the tool changing arm of the tool changing mechanism can smoothly buckle the tool bar 30 on the tool sleeve 20 to execute tool changing operation.

When the tool holder 20 is to be brought back to the original position after the tool changing operation is completed, the displacement member 64b is controlled to move to the first position P1, when the tool holder 20 is disengaged from the guide member 63 and enters the supporting member 14, the free end 653a of the fixing rod 653 will first abut against the first stopper 69, so that the first clamping block 651 stays at the fixed position, however, the displacement member 64b will still retreat to the inside of the cylinder 64a for a short distance due to the design of the movement stroke, so as to drive the second clamping block 652 to retreat relative to the first clamping block 651, thereby increasing the distance between the first clamping block 651 and the second clamping block 652, so that the first clamping block 651 and the second clamping block 652 are restored to the space shown in fig. 4, which is reserved for the tool holder 20 on the chain to pass through. At the same time, the head 41b of the fixed rod 41 on the knife holder 20 is inserted into the first side hole 12a of the base 12 of the corresponding carrier 10, the head 41b guides the brake lever 42 to move back toward the second side hole 12b, and after the head 41b passes through the central axis of the brake lever 42, the pushing force of the pushing member 43 continues to make the abutment shoulder 42d of the brake lever 42 abut against the stopper 41c of the fixed rod 41 again, so as to prevent the knife holder 20 from being released from the carrier 10 improperly.

In summary, the knife pouch and the supporting body of the present invention have good coupling performance through the arrangement of the locking unit therebetween, so that the chain has good carrying effect on the knife pouch, and the knife pouch is free from loosening; secondly, the supporting piece for guiding the knife pouch adopts a general rod body which is matched with the through hole on the knife pouch to pass through, the matching mode solves the defects that the prior track structure must be matched with the outer contour of the knife pouch to make a special channel to increase the processing procedure and the cost expenditure, and simultaneously solves the defect that the prior track structure cannot be suitable for knife pouches with different specifications or different outer contours to be general. In addition, the action of the unlocking unit and the knife conveying mechanism is controlled by a processor, which is not the key point of the improvement of the present invention, and is not described herein again.

The above description is only a preferred and practical embodiment of the present invention, and all equivalent changes to the application of the present invention in the specification and claims should be considered as being included in the scope of the present invention.
