As a direct product of the stamping and pressing process, the quality and production efficiency of stamped parts directly affect the performance of the final product.

[0003] With the replacement of processed parts, it is necessary to change the stamping die at any time to adapt to the production needs of different stamping parts. However, at present, when changing the die, it is usually installed and aligned manually. Due to human visual errors and differences in operating techniques, it is difficult to accurately position it in the center position. Multiple adjustments are required, which is quite troublesome. Even a small positioning deviation may cause the stamping part to shift in position during the stamping process, thus affecting the stamping accuracy. To solve the above problems, a stamping part stable movement guide press-fitting fixture is proposed. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] The positioning plate is L-shaped, and the upper part of the positioning plate slides on the top of the machine body.

[0010] As a further description of the above technical solution:

[0011] The positioning plate is slidably connected to the outer wall of the positioning rod. There are two sets of positioning plates and positioning rods, and the two sets of positioning plates and positioning rods are symmetrically arranged with the center line of the machine body as the axis of symmetry.

[0012] As a further description of the above technical solution:

[0013] The left side of the support block has a through-hole and a limiting groove. The limiting block is slidably connected to the inner wall of the limiting groove. The front end of the positioning block is hinged to a connecting block.

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, after the mold is placed between the two sets of positioning plates at the top of the machine body, the rocker arm is rotated to drive the bidirectional threaded rod to rotate and connect with the two sets of positioning plates by threads. This allows the two sets of positioning plates to move stably towards the middle, pre-clamp the mold and directly position it at the center. No manual adjustment is required, which improves the speed and accuracy of positioning, reduces the deviation of manual positioning, and enables the stamping parts to move and press stably.

[0022] 2. In this utility model, after the positioning plate moves and drives the push rod to move to extrude the mold, the push rod moves backward to pull the connecting block and the positioning block, which are slidably connected in the limiting groove with the limiting block. This makes the positioning block move stably towards the center, thereby pushing the two sides of the mold and further stably positioning and guiding the mold to the center of the machine body mounting table for accurate alignment with the stamping part. This further improves the installation efficiency and the accuracy and stability of the stamping part processing. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a stamping part stable moving guide press fitting fixture, including a body 1. The body 1 serves as the main body of the press fitting fixture machine and is the core load-bearing structure of the entire fixture, ensuring that the fixture can withstand various external forces during operation and maintain overall stability and reliability. A clamping assembly for pre-clamping the mold fixture is provided at the top middle part of the body 1. The clamping assembly includes a positioning plate 2 that pushes the mold to move towards the middle for pre-positioning. A fixing block 22 that supports a bidirectional threaded rod 21 is fixedly connected to the middle bottom of the body 1. A bidirectional threaded rod 21 that drives two sets of positioning plates 2 to move towards the middle is rotatably connected through the middle of the fixing block 22. A rocker arm 23 that drives the bidirectional threaded rod 21 to rotate is fixedly connected to the front surface of the bidirectional threaded rod 21. The positioning plate 2 is threadedly connected to the thread on the front outer wall of the bidirectional threaded rod 21. A positioning rod 24 that increases the stability of the movement of the positioning plate 2 is fixedly connected to the front surface of the body 1.

[0030] Reference Figure 1 , Figure 2 and Figure 3The left and right sides of the machine body 1 are provided with positioning components that stably guide the mold to the center for installation. The positioning components include multiple sets of positioning blocks 3 that stably position the mold in the center. The outer wall of the top of the middle part of the positioning block 3 is fixedly connected with a limiting block 33 that restricts the positioning block 3 to move only left and right. The left and right sides of the positioning plate 2 are fixedly connected with support blocks 37 that provide support.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The positioning plate 2 is L-shaped, which allows it to be threadedly connected to the bidirectional threaded rod 21. At the same time, the upper part can push the mold to move towards the center. The upper part of the positioning plate 2 slides on the top of the machine body 1. The positioning plate 2 is slidably connected to the outer wall of the positioning rod 24. There are two sets of positioning plates 2 and positioning rods 24, and the two sets of positioning plates 2 and positioning rods 24 are symmetrically arranged with the center line of the machine body 1 as the axis of symmetry. Setting two sets can increase the stability of movement and the accuracy of positioning.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The left side of the support block 37 has a through-hole and a limiting groove 38 that works with the limiting block 33 to stably restrict movement to the left and right. The limiting block 33 is slidably connected to the inner wall of the limiting groove 38. The front end of the positioning block 3 is hinged to a connecting block 32 that pulls the positioning block 3 towards the center and pushes the mold to be positioned in the middle. The right end of the connecting block 32 is hinged to a slider 31 that pulls the connecting block 32. The front part of the positioning plate 2 has a groove 36 that provides space for the slider 31 to move. The rear surface of the slider 31 is fixedly connected to a push rod 35 that moves forward after being squeezed by the mold, pushing the slider 31 to pull the connecting block 32 and the positioning block 3 to move and position the mold in the middle. The rear surface of the slider 31 is fixedly connected to a spring 34 that stretches the slider 31 towards the front. After the slider 31 moves forward, the spring 34 can be stretched and the slider 31 can be reset by the reverse force of the stretched spring 34. The other end of the spring 34 is fixedly connected to the inner wall of the groove 36. The spring 34 is sleeved on the outer wall of the push rod 35.

[0033] Furthermore, the push rod 35 passes through and slides to the upper rear end of the positioning plate 2. The slider 31 is set in an I-shape, which allows it to be hinged to two sets of connecting blocks 32. Multiple sets of support blocks 37, connecting blocks 32, and positioning blocks 3 are provided, and these multiple sets of support blocks 37, connecting blocks 32, and positioning blocks 3 are symmetrically arranged with the center line of the machine body 1 as the axis of symmetry. Positioning blocks 3 are provided on both the left and right sides of the two sets of positioning blocks 3. The mold can be stably positioned at the center by multiple sets of positioning blocks 3 and two sets of positioning blocks 3, without the need for manual adjustment of the positioning, which improves the positioning speed and accuracy, reduces the deviation of manual positioning, and thus allows the stamping parts to be moved and pressed stably. By accurately positioning at the center, the accuracy of the stamping parts moving and pressing tooling is improved.

[0034] Working principle: In use, firstly, place the mold to be pressed at the top center of the machine body 1, between the two sets of positioning plates 2. At this time, rotate the rocker arm 23. Since the rocker arm 23 is fixedly connected to the front surface of the bidirectional threaded rod 21, the rotation of the rocker arm 23 drives the bidirectional threaded rod 21 to rotate. The bidirectional threaded rod 21 is threadedly connected to the positioning plate 2, which drives the two sets of positioning plates 2 to move towards the center along the threaded part of the front outer wall of the bidirectional threaded rod 21. The positioning plate 2 is L-shaped, and its upper part slides at the top of the machine body 1 and is slidably connected to the positioning rod 24. The positioning rod 24 is fixed to the front surface of the machine body 1, providing guidance for the movement of the positioning plate 2 and increasing its stability. The two sets of positioning plates 2 and the positioning rod 24 are symmetrically arranged about the center line of the machine body 1, so that the positioning plate 2 can move towards the center smoothly and accurately, initially clamping the mold and pushing the mold to the center position for pre-positioning.

[0035] Furthermore, when the mold is initially clamped by the positioning plate 2 and moves towards the center, the mold will squeeze the push rod 35, causing the push rod 35 to move towards the front surface and push the slider 31 to slide in the groove 36. The slider 31 is I-shaped, which facilitates hinged connection with the two sets of connecting blocks 32. The movement of the slider 31 drives the hinged connecting block 32 to move, and the connecting block 32 pulls the positioning block 3 to move towards the center. During this process, when the slider 31 moves forward, the spring 34 is stretched, generating a reverse force. As the mold gradually approaches the center position, multiple positioning blocks 3 accurately position the mold from different directions, working together with the positioning plate 2 to stably position the mold at the center of the machine body 1.

[0036] By cooperating with the clamping and positioning components, the mold can be accurately positioned at the center without manual adjustment, greatly improving the speed and accuracy of positioning and reducing the deviation of manual positioning. At the same time, in the subsequent stamping process, since the mold has been accurately and stably positioned, the stamped parts can move stably under the guidance of the tooling, thus ensuring the accuracy of the stamping process and improving the quality and efficiency of the entire stamping production.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
