As shown in fig. 2 to 5, the assembly jig 100 for a level indicator according to an embodiment of the present application includes: a positioning module 20 and a driving member 30.

Specifically, the positioning module 20 is provided with a press mold 21 and a positioning mold 22 opposite to each other in the vertical direction, the positioning mold 22 can bear the level indicator, the press mold 21 is provided above the positioning mold 22, and the level indicator can be pressed down. When assembling the horizontal indicator, it is necessary to place steel balls in the horizontal indicator before the pressing die 21 presses, the steel balls are placed in the limiting groove 2212, and the steel balls can roll towards the second end 2212b under the guidance of the limiting groove 2212 due to the inclined bearing surface 2211 of the positioning die 221. The metal sensor 222 assembled to the positioning mold 221 may detect the steel ball at the second end 2212b, and when the metal sensor 222 detects the metal, it indicates that the steel ball has been placed into the level indicator, and at this time, the driving member 30 may drive the pressing mold 21 to move toward the positioning mold 22 along the first direction, so as to implement the pressing of the level indicator.

According to the assembly jig 100 for the level indicator, the metal sensor 222 can detect whether steel balls are leaked from the level indicator to be assembled, so that the yield of the level indicator can be effectively improved.

Optionally, the bearing surface 2211 is at an angle of 1-5 ° to the horizontal. Through setting up bearing surface 2211 and horizontal plane to be certain angle, can make the steel ball remove to the lower one end of spacing groove 2212 under the effect of gravity, second end 2212b, but can not remove outside spacing groove 2212 to make the steel ball of placing in the horizontal indicator all roll to the second end 2212b of spacing groove 2212, and then be convenient for metal sensor 222 detects the steel ball in second end 2212b department, and then prevent to leak the steel ball in the assembly process, and then improve the yields of horizontal indicator.

Illustratively, the angle between the bearing surface 2211 and the horizontal plane may be 1 °,2 °,3 °, 4 °, 5 °.

Preferably, the bearing surface 2211 is at an angle of 3 ° to the horizontal.

As shown in fig. 4-6, in some embodiments, the metal sensor 222 is located below the limit groove 2212, the metal sensor 222 is provided with a main body portion 2221 and a detection hole 2222, the main body portion 2221 is disposed around the detection hole 2222, and the detection hole 2222 is opposite to the second end 2212b from top to bottom.

Specifically, when the level indicator is assembled, the steel ball rolls to the second end 2212b under the guide of the limit groove 2212 after being placed in the level indicator, and the steel ball can be located at the detection hole 2222 inside the main body 2221 because the detection hole 2222 of the metal sensor 222 is opposite to the second end 2212b, so that whether the steel ball exists or not can be detected more accurately.

Thus, the accuracy of detecting the presence or absence of the steel ball by the metal sensor 222 can be improved.

As shown in fig. 4-5, further, the limiting groove 2212 is provided with a through groove 2212c penetrating the positioning mold 221 along the up-down direction, specifically, the through groove 2212c penetrates the positioning mold 221 corresponding to the second end 2212b, it is known that the through groove 2212c is located right above the detection hole 222 at this time, and the middle medium of the positioning mold 221 located between the steel ball of the second end 2212b and the detection hole 222 is removed and replaced by air for filling, and due to the elimination of the middle medium of the positioning mold 221, the accuracy of detecting whether the steel ball exists by the metal sensor 222 can be effectively improved.

As shown in fig. 4 to 5, alternatively, the through groove 2212c extends toward the first end 2212a along the extending direction of the limit groove 2212 and is vertically opposite to the metal sensor 222 located at a portion directly under the limit groove 2212, so that in addition to the positioning mold 221 vertically opposite to the detection hole 222, the positioning mold 221 located directly above the metal sensor 222 located at the remaining portion directly under the limit groove 2212 is eliminated to further improve the accuracy of detecting the presence or absence of the steel ball by the metal sensor 222. Optionally, the through groove 2212c does not extend to the first end 2212a (see fig. 4) or extends to the first end 2212a (not shown)

As shown in fig. 4, in some embodiments, the positioning mold 221 is further provided with a positioning groove 2213, the positioning groove 2213 is formed by recessing downwards from the top surface of the positioning mold 221, the positioning groove 2213 is used for accommodating the horizontal indicator, and the bearing surface 2211 is disposed at the bottom of the positioning groove 2213. The top surface of the positioning die 221 and the bearing surface 2211 are parallel to each other.

Specifically, when the horizontal indicator is assembled by the positioning mold 221, the horizontal indicator can be placed in the positioning groove 2213, and since the positioning groove 2213 is formed by downwardly recessing the positioning mold 221, an operator can be guided to avoid that the placement position of the horizontal indicator is not in place when the horizontal indicator is placed, the bearing surface 2211 at the bottom of the positioning groove 2213 can bear the horizontal indicator, and when the pressing mold 21 is pressed downward, the bearing surface 2211 can be matched with the pressing mold 21 to press the horizontal indicator.

Therefore, the horizontal indicator can be positioned, and the assembly efficiency of the horizontal indicator is improved.

As shown in fig. 3, in some embodiments, the first direction is perpendicular to the pressing surface 2121 and the bearing surface 2211. When the horizontal indicator is pressed by the pressing surface 2121 and the bearing surface 2211, if the pressing surface 2121 and the bearing surface 2211 are not perpendicular to the first direction, uneven stress on the horizontal indicator is caused, and after the pressing is completed, white spots caused by stress concentration can appear on the horizontal indicator, so that the attractiveness of the horizontal indicator is affected, and the service life of the horizontal indicator is also affected. Therefore, the stress of the horizontal indicator is more uniform during pressing, and the yield of the horizontal indicator is improved.

As shown in fig. 7-8, in some embodiments, a pressing block 2122 formed by protruding downward is provided at the lower end of the pressing die 21, the pressing block 2122 is provided in the circumferential edge of the pressing die 21, and the pressing surface 2121 is provided on the bottom surface of the pressing block 2122.

Specifically, when the horizontal indicator is assembled by the positioning module 20, after the horizontal indicator is placed in the positioning groove 2213 and the steel ball is placed, the horizontal indicator can be pressed by the pressing die 21, and at this time, the pressing block 2122 protruding from the lower end of the pressing die 21 can press against the center of the horizontal indicator, so that the horizontal indicator is uniformly pressed together.

Therefore, the stress of the horizontal indicator is more uniform when the horizontal indicator is pressed, and the yield of the horizontal indicator is improved.

As shown in fig. 2-3, in some embodiments, the assembly fixture 100 of the level indicator further includes a frame body 10, where the frame body 10 includes a bottom plate 11, a vertical plate 13, and a top plate 12, the bottom plate 11 is horizontally disposed below the positioning mold 22, the top plate 12 is above the pressing mold 21, the driving member 30 connects the top plate 12 and the pressing mold 21, the vertical plate 13 connects the bottom plate 11 and the top plate 12, and the pressing mold 21 is slidably connected with the vertical plate 13.

Specifically, the driving member 30 is disposed on the top plate 12, so that the driving member 30 drives the pressing mold 21 to move in the first direction to press the horizontal indicator, when the pressing mold 21 and the positioning mold 22 are pressed, the top plate 12 and the bottom plate 11 will receive a reaction force, and the vertical plate 13 is disposed between the top plate 12 and the bottom plate 11, so as to provide support for the top plate 12 and the bottom plate 11, so that the frame 10 has high structural strength, and damage to the assembly jig 100 after long-term use is avoided. And the die 21 is slidably connected to the riser 13 to provide support to the die 21 when the drive member 30 drives the die 21 in the first direction, thereby preventing the die 21 from moving away from the first direction.

Therefore, the driving piece 30 and the positioning module 20 can be supported, the structural strength is improved, and the service life of the assembly jig 100 of the level indicator is further prolonged.

Further, the press mold 21 and the vertical plate 13 are slidably connected through a limiting module 40, the limiting module 40 is provided with a limiting sliding rail 41 and a limiting sliding block 42, the limiting sliding rail 41 is arranged on the vertical plate 13, the limiting sliding rail 41 extends along the first direction, the limiting sliding block 42 is arranged on the press mold 21, and the limiting sliding block 42 can slide on the limiting sliding rail 41.

Specifically, the limiting slide rail 41 is disposed on the vertical plate 13, the limiting slide block 42 can drive the die 21 to slide along the limiting slide rail 41 in the first direction, when the driving piece 30 drives the die 21 to press the horizontal indicator, the die 21 has a tendency of deflection under pushing of a reaction force, at this time, due to the fact that the limiting slide block 42 is disposed on the die 21, the die 21 can be limited by the mutual matching of the limiting slide block 42 and the limiting slide rail 41, deflection of the die 21 is avoided, and further assembly reliability of the assembly jig 100 to the horizontal indicator is improved, and due to the fact that the die 21 can move along the first direction under the matching of the limiting slide rail 41 and the limiting slide block 42, a movement track of the die 21 can be guaranteed, and a lamination effect to the horizontal indicator is improved.

Thus, the movement locus of the press die 21 can be guided, and the assembly efficiency of the level indicator can be improved.

As shown in fig. 2, alternatively, the press mold 21 is provided with a fixing plate 211 and a press mold 212 located below the fixing plate 211 and connected to the fixing plate 211, the fixing plate 211 is connected to the limit slider 42, and the press surface 2121 is provided on the bottom surface of the press mold 212. The pressing die 212 is arranged on the fixing plate 211, and the fixing plate 211 is connected with the limit sliding block 42 to guide the movement track of the pressing die 212. Therefore, the stress of the horizontal indicator is more uniform during pressing, and the yield of the horizontal indicator is improved.

It should be noted that, the connection manner between the press mold 212 and the fixing plate 211 is not particularly limited, for example, the press mold 212 and the fixing plate 211 may be connected by a bolt, a buckle, or an inserting connection, and may be selected according to actual needs.

Alternatively, the limiting slide rail 41 is detachably connected with the vertical plate 13, and the limiting slide block 42 is detachably connected with the fixing plate 211. The spacing between the press mold 21 and the positioning mold 22 affects the specification and the size of the horizontal indicators, so when assembling the horizontal indicators with different specifications, the limiting slide rails 41 with different lengths can be replaced, the universality of the assembly jig 100 is improved, the fixing plate 211 can be stably moved along the first direction through the matching of the limiting slide rails 41 and the limiting slide blocks 42, and the limiting slide blocks 42 and the fixing plate 211 can be detached, so that the press mold 21 and the fixing plate 211 can be conveniently detached.

Therefore, the assembling and disassembling difficulty can be reduced when the press-fit die 21 needs to be replaced, and the production efficiency of the assembling jig 100 of the level indicator can be improved.

Optionally, a side of the vertical plate 13 facing the limiting sliding rail 41 is provided with a mounting groove 131 extending along the first direction, and the limiting sliding rail 41 is detachably arranged in the mounting groove 131. Through setting up mounting groove 131 on riser 13, can fix a position spacing slide rail 41, after changing spacing slide rail 41, can avoid repositioning the mounted position of spacing slide rail 41, and then reduce spacing slide rail 41's assembly degree of difficulty, improve the assembly efficiency of equipment tool 100.

As shown in fig. 2, further alternatively, the driving member 30 is rotatably connected to the fixing plate 211.

Specifically, when the driving member 30 drives the press mold 21 to press the horizontal indicator, due to the inclined arrangement of the horizontal indicator on the positioning mold 22, there may be misalignment between the center of the driving member 30 and the center of the fixing plate 211 in the up-down direction, that is, there may be a certain misalignment in the horizontal direction, so that the driving member 30 cannot effectively drive the fixing plate 211 to move in the first direction, and thus uneven stress is caused between the press mold 21 and the horizontal indicator, and for this reason, the fixing plate 211 is rotatably connected with the driving member 30, specifically, the fixing plate 211 is connected with the driving member 30 through a fisheye joint, so as to compensate for the distance between the center of the driving member 30 and the center of the fixing plate 211 in the horizontal direction, so that the driving member 30 can drive the fixing plate 211 to move in the first direction, and the press mold 21 is more adhered to the horizontal indicator.

Therefore, the stress of the horizontal indicator is more uniform during pressing, and the yield of the horizontal indicator is improved.

Alternatively, the fixing plate 211 is detachably connected to the pressing die 212. The fixing plate 211 is detachably connected with the press-fit die 212, and the press-fit die 212 can be detached when the press-fit die 212 needs to be overhauled or replaced with different specifications. The versatility of the assembly jig 100 is improved.

As shown in fig. 1, a fitting device 1 according to another embodiment of the present application, the fitting device 1 includes: the assembly jig 100 and the display module 200 according to any of the above embodiments. The display module 200 is electrically connected to the metal sensor 222, and can display when the metal sensor 222 detects metal.

As shown in fig. 1, the number of the assembly fixtures 100 is optionally plural, and the display module 200 is provided with a display lamp corresponding to each assembly fixture 100, and when the display lamp is turned on, it indicates that the metal sensor 222 detects the steel ball.

Specifically, when the horizontal indicator is assembled, the metal sensor 222 can detect the steel balls in real time, and transmit the detection result to the display module 200 in real time, and the display module 200 displays the steel ball state on each assembly jig 100, so that whether the steel balls on the horizontal indicator to be assembled meet the requirement or not can be known, and the horizontal indicator which leaks the steel balls can be timely supplemented.

Therefore, the level indicator has higher yield.

As shown in fig. 1, further, the assembling device 1 further includes: at least one start switch 300; the start switch 300 is electrically connected to the driving member 30, and the driving member 30 can drive the press mold 21 to move toward the positioning mold 22 in the first direction when the start switch 300 is started. After the placement of the level indicator is completed, an operator needs to operate the start switch 300 to start the assembly device 1, so that the assembly device 1 can be prevented from being started by mistake when the operator places the level indicator. Thus, the safety can be improved while improving the assembling efficiency of the level indicator.

As shown in fig. 1, the number of the start switches 300 is optionally two. After the level indicator to be assembled is placed, the operator is required to trigger the two start switches 300 at the same time, and both hands of the operator are far away from the driving member 30, so that injury of the operator can be avoided.
