The insertion assembly includes a clamping member and a pushing member, both of which can slide vertically relative to the frame. The insertion assembly has a first state where both the clamping member and the pushing member are on top, a second state where the clamping member is on the bottom and the pushing member is on top, a third state where both the clamping member and the pushing member are on the bottom, and a fourth state where the clamping member is on top and the pushing member is on the bottom. The insertion assembly is configured to be able to... In the first state, the component moves to the loading position and switches to the second state at the loading position to clamp the spring piece. After switching back to the first state, the insertion component moves from the loading position back to the caliper mounting position and switches to the third state at the caliper mounting position to press the spring piece onto the caliper body. At this time, the clamping member presses on the middle of the spring piece, and the pushing member presses on the tail end of the spring piece. The insertion component is configured to move forward at the caliper mounting position in the third state and push the head end of the spring piece into the caliper head. When the insertion component at the caliper mounting position switches to the fourth state, the insertion component can move forward to fully push the spring piece into the caliper head.

[0006] Optionally, the pushing member includes a base, a first pushing block, a second pushing block, and an elastic member. The first pushing block and the second pushing block are both horizontally slidably disposed within the base. The two ends of the elastic member are respectively connected to the first pushing block and the second pushing block. When the elastic member is in its natural state, the front end face of the first pushing block is located in front of the front end face of the second pushing block. When the elastic member is in a compressed state, the front end face of the first pushing block is located behind the front end face of the second pushing block. The position of the rear end of the spring piece held by the clamping member corresponds horizontally to the position of the front end face of the second pushing block.

[0009] Optionally, the feeding assembly includes a vibratory feeder and a flipping block both mounted on the frame. The vibratory feeder is used to sequentially output the spring pieces. The spring pieces are conveyed backward along an inclined plane from the output end of the vibratory feeder to the flipping block. The flipping block can rotate relative to the frame around a rotation axis set in the front-back direction to flip the spring pieces to a horizontal state.

[0010] Optionally, the feeding assembly further includes a trough, grippers, and a feeding element. The trough extends in the front-to-back direction, and the grippers are movable relative to the frame in the left-to-right direction. The trough has a first position, a second position, and the feeding position. The grippers are configured to transfer the spring piece on the flipping block to the first position of the trough. The feeding element is configured to move relative to the frame in the vertical, front-to-back, and left-to-right directions to move the spring piece from the first position to the second position and the feeding position in sequence. The frame has a first pressing block at the second position, which is used to press the spring piece located at the second position downward. The frame has a second pressing block at the feeding position, which is used to press the spring piece located at the feeding position upward onto the gripper.

[0011] Optionally, four material-pulling components are provided, arranged in pairs. The two material-pulling components in the same group can be inserted into the groove at positions in front of and behind the spring piece, respectively, and then push the spring piece backward. The four material-pulling components can move synchronously.

[0012] Optionally, the groove is provided with a clearance block, and the clearance block is connected to the groove via a compression spring. The gripper can push down against the clearance block when placing the spring piece.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0037] like Figures 1 to 14 As shown, this utility model provides a caliper 400 spring sheet 500 installation device, including a frame 100, a feeding assembly 200 and an insertion assembly 300.

[0038] The frame 100 has a loading position 233 and a caliper mounting position 110. The loading assembly 200 is located on the frame 100 and is used to sequentially transport the bent spring sheet 500 from front to back to the loading position 233. The insertion assembly 300 is disposed on the frame 100 and can reciprocate between the loading position 233 and the caliper mounting position 110. The insertion assembly 300 includes a clamping member 310 and a pushing member 320, both of which can slide relative to the frame 100 in the vertical direction. The insertion assembly 300 has a first state in which both the clamping member 310 and the pushing member 320 are on top, a second state in which the clamping member 310 is on the bottom and the pushing member 320 is on top, a third state in which both the clamping member 310 and the pushing member 320 are on the bottom, and a fourth state in which the clamping member 310 is on top and the pushing member 320 is on the bottom. The insertion assembly 300 is configured to move to the loading position in the first state. Position 233, and switch to the second state at the loading position 233 so that the clamping member 310 clamps the spring piece 500; after switching back to the first state, the insertion component 300 can move from the loading position 233 back to the caliper mounting position 110 and switch to the third state at the caliper mounting position 110 to press the spring piece 500 onto the scale body 410 of the caliper 400. At this time, the clamping member 310 presses the middle part of the spring piece 500, and the pushing member 320 presses the tail end of the spring piece 500; the insertion component 300 is configured to move forward at the caliper mounting position 110 in the third state and push the head end of the spring piece 500 into the scale head 420 of the caliper 400. When the insertion component 300 at the caliper mounting position 110 switches to the fourth state, the insertion component 300 can move forward to fully push the spring piece 500 into the scale head 420 of the caliper 400.

[0039] Understandably, during installation, the insertion component 300 first moves to the loading position 233 in the first state; then, the insertion component 300 switches to the second state and clamps the spring piece 500 at the loading position 233, at which point the spring piece 500 is in a bent state; then, the insertion component 300 switches back to the first state and moves back to the loading position. Figure 5 The caliper mounting position 110 is shown; then insert component 300 as shown. Figure 6 The switch to the third state is shown to press the spring piece 500 onto the scale body 410 of the caliper 400. At this time, the spring piece 500 is in a flat state due to the pressure of the clamping member 310 and the pushing member 320. Then the insertion assembly 300 moves forward and as shown... Figure 7 As shown, the tip of the spring piece 500 is pushed into the head 420 of the caliper 400; then the insertion component 300 switches to the fourth state. At this time, because the tip of the spring piece 500 is pressed against the head 420 of the caliper 400 and the tail is pressed against the pusher 320, the spring piece 500 can be kept in a straight state. Then the insertion component 300 continues to move forward to place the spring piece 500 as shown. Figure 10The spring 500 is fully pushed into the head 420 of the caliper 400 as shown. The device of this invention can automatically assemble the bent spring 500 and the caliper 400 by repeating the above steps, which can significantly improve assembly efficiency and reduce labor costs.

[0040] like Figures 5 to 11 As shown, in one embodiment of this utility model, the pushing member 320 includes a base 321, a first pushing block 322, a second pushing block 323, and an elastic member 324. The first pushing block 322 and the second pushing block 323 are both horizontally slidably disposed within the base 321. The two ends of the elastic member 324 are respectively connected to the first pushing block 322 and the second pushing block 323. When the elastic member 324 is in the following position... Figures 5 to 9 In the natural state shown, the front end face of the first top block 322 is located in front of the front end face of the second top block 323. At this time, there is a certain gap between the first top block 322 and the second top block 323 in the front-rear direction, which provides space for the sliding of the first top block 322 relative to the second top block 323; when the elastic member 324 is in such a state... Figure 10 and Figure 11 In the compressed state shown, the front end face of the first top block 322 is located behind the front end face of the second top block 323; the position of the rear end of the spring piece 500 held by the clamping member 310 corresponds horizontally to the position of the front end face of the second top block 323, so that the second top block 323 can be... Figure 11 The spring 500 is inserted into the head 420 of the caliper 400 as shown to fully insert the spring 500 into the head 420, preventing the tail end of the spring 500 from being exposed outside the head 420.

[0041] like Figures 5 to 10 As shown, in one embodiment of this utility model, a push cylinder 325 is provided on the base 321. The push cylinder 325 is configured to reciprocate in the front-rear direction to push and pull the second push block 323, thereby realizing the sliding of the second push block 323. The second push block 323 and the elastic element 324 push the first push block 322 to slide. The elastic element 324 can be a compression spring. It should be noted that... Figure 5 and Figure 6 The push cylinder 325 in the middle is in the retracted state. Figures 7 to 10 The push cylinder 325 is in the extended state. Furthermore, the displacement of the first push block 322 relative to the second push block 323 can be achieved by moving the insertion assembly 300 as a whole in the front-rear direction. Specifically, when the insertion assembly 300 is in the extended state... Figure 9 When positioned, the front end face of the first top block 322 is in front of the front end face of the second top block 323. At this time, the elastic element 324 is not compressed. However, when the insertion component 300 continues to move forward a short distance, the insertion component is positioned... Figure 10 At the position shown, the front face of the first top block 322 is as follows: Figure 11The position shown is behind the front end face of the second top block 323, and the elastic element 324 is in a compressed state at this time.

[0042] like Figure 12 As shown, in one embodiment of this utility model, the clamping member 310 includes a base 311 extending in the front-rear direction and two clamping plates 312 located on the left and right sides of the base 311 and arranged parallel to each other. A tension spring (not shown in the figure) is provided between the two clamping plates 312. The bottom surfaces of the two clamping plates 312 are located below the bottom surface of the base 311, and the distance between the two clamping plates 312 is adapted to the width of the spring piece 500. When the clamping member 310 clamps the spring piece 500, the two clamping plates 312 are spread apart and the distance between them increases, at which time the tension spring is in a stretched state. The above-mentioned clamping member 310 structure can be used to clamp the bent spring piece 500, that is, to clamp the spring piece 500 from the width direction of the spring piece 500, so that the clamping and transfer action can be realized regardless of the degree of bending of the spring piece 500.

[0043] like Figure 13 As shown, in one embodiment of this utility model, the feeding assembly 200 includes a vibratory feeder 210 and a tilting block 220 both mounted on the frame 100. The vibratory feeder 210 is used to sequentially output spring pieces 500. The spring pieces 500 in the vibratory feeder 210 are all in a straight state. The vibratory feeder 210 can straighten several scattered strip-shaped spring pieces 500 and sequentially transport them to the output end of the vibratory feeder 210. The specific structure and principle of the vibratory feeder 210 for transporting strip-shaped parts are conventional technical means in the field and will not be described in detail here. The spring pieces 500 are transported backward along an inclined plane from the output end of the vibratory feeder 210 to the tilting block 220. By setting an inclined plane to transport the spring pieces 500, the spring pieces 500 can automatically slide downward along the inclined plane and be flush with the lower edge of the inclined plane, thereby realizing the automatic alignment of several spring pieces 500 at the output end of the vibratory feeder 210. In addition, the flipping block 220 can rotate relative to the frame 100 around a rotation axis set in the front-back direction to flip the spring piece 500 to a horizontal state, which facilitates the subsequent clamping and transfer of the spring piece 500 by the gripper 240.

[0044] like Figure 14As shown, in one embodiment of this utility model, the feeding assembly 200 further includes a trough 230, a gripper 240, and a feeding element 250. The trough 230 extends in the front-to-back direction, and the gripper 240 is movable relative to the frame 100 in the left-to-right direction. The trough 230 has a first position 231, a second position 232, and a feeding position 233. The gripper 240 is configured to transfer the spring piece 500 on the flipping block 220 to the first position 231 of the trough 230. The feeding element 250 is configured to move relative to the frame 100 in the left-to-right direction. The frame 100 moves vertically, forward and backward, and left and right to move the spring piece 500 from the first position 231 to the second position 232 and the loading position 233 in sequence. A first pressing block 120 is provided at the second position 232 of the frame 100. The first pressing block 120 is used to press down and bend the spring piece 500 located at the second position 232, so as to press the straight spring piece 500 into a curved spring piece 500. The first pressing block 120 can be positioned above the groove 230 and moves from top to bottom to achieve the pressing action. A second pressing block 130 is provided at the loading position 233 of the frame 100. The second pressing block 130 can be positioned below the groove 230. The second pressing block 130 is used to move upward and press the spring piece 500 located at the loading position 233 between the two clamping plates 312 on the clamping member 310.

[0045] like Figure 14 As shown, in one embodiment of this utility model, four feeding components 250 are provided, arranged in pairs. The two feeding components 250 in the same group can be inserted into the groove 230 at positions in front of and behind the spring piece 500, respectively, and push the spring piece 500 backward. The four feeding components 250 can move synchronously. Specifically, the four feeding components 250 can move upward synchronously, then move to the right synchronously, and then move downward synchronously to insert into the groove 230. Then, the four feeding components 250 can move backward synchronously to move the spring piece at the first position 231 to the second position 232, and move the spring piece 500 at the second position 232 to the loading position 233.

[0046] like Figure 14 As shown, in one embodiment of this utility model, a clearance block 600 is provided on the groove 230. The clearance block 600 and the groove 230 are connected to each other by a compression spring. The gripper 240 can press down against the clearance block 600 when placing the spring piece 500, so that the gripper 240 can smoothly place the spring piece 500 into the groove 230. After the gripper 240 leaves, the clearance block 600 can be reset under the action of the compression spring. The reset clearance block 600 can provide guidance for the movement of the spring piece 500 in the front-back direction. Specifically, the clearance block 600 can be set as a U-shaped structure. The two ends of the U-shaped structure can be pressed down by the two ends of the gripper 240, and the middle of the U-shaped structure can be used to support the spring piece 500 and provide guidance for the movement of the spring piece 500.

[0047] like Figure 13As shown, in one embodiment of this utility model, the flipping block 220 is provided with another clearance block 600. When the gripper 240 clamps the spring piece 500, it can press down against the clearance block 600 on the flipping block 220, so that the gripper 240 can smoothly clamp the spring piece 500. After the gripper 240 leaves, the clearance block 600 can be reset under the action of the compression spring. The reset clearance block 600 can provide guidance for the movement of the spring piece 500 in the front-back direction. Specifically, the clearance block 600 can be set as a U-shaped structure. The two ends of the U-shaped structure can be pressed down by the two ends of the gripper 240, and the middle of the U-shaped structure can be used to support the spring piece 500 and provide guidance for the movement of the spring piece 500.

[0048] like Figure 14 As shown, in one embodiment of this utility model, the feeding member 250 is L-shaped with the short side vertically arranged.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
