Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing, and in particular to a positioning device for stamping automotive parts. Background Technology

[0002] With the rapid development of the automotive industry, stamping is a key process in the production of automotive parts, which has a significant impact on the dimensional accuracy, shape accuracy and surface quality of the parts. Positioning devices can ensure the accurate positioning of parts during the stamping process, thereby improving product quality and production efficiency. Therefore, a positioning device for stamping automotive parts is particularly needed.

[0003] A stamping positioning mechanism for automotive parts, authorized by announcement number CN222198523U, includes a base plate. Slide grooves are formed on both sides of the upper surface of the base plate. Slide rods are installed inside the slide grooves, and sliders are mounted on the bodies of the slide rods. Movable plates are fixedly connected to the upper surfaces of the sliders. Fixed plates are fixedly connected to the upper ends of the outer walls of the movable plates near the center of the base plate. Multiple damping rods are provided on both sides of the fixed plates. In this invention, a servo motor drives a gear disk to rotate, which in turn moves a gear plate. This gear plate, through a connecting rod, moves a slider, which in turn moves a fixed plate. This allows the fixed plate to be moved to different positions to fix plates of different sizes, thus avoiding the need for manual adjustment by operators in existing positioning mechanisms.

[0004] However, in the aforementioned stamping positioning mechanism for automotive parts, manual adjustment is still required when clamping and holding plates of different thicknesses, and it does not have the function of adjusting the limit in the width direction.

[0005] To address the aforementioned problems, a positioning device for stamping automotive parts is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning device for stamping automotive parts, so as to solve the problem of the existing positioning devices for stamping automotive parts mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for stamping automotive parts, comprising a stamping machine body, positioning mechanisms provided on both sides of the stamping machine body, and an auxiliary mechanism provided on the side of the positioning mechanism closer to the stamping direction;

[0008] The positioning mechanism includes a mounting bracket that is slidably connected to both sides of the stamping machine body. A first movable plate is slidably connected to the inner wall of the mounting bracket. A first bidirectional threaded rod is provided above the first movable plate. Two sets of mounting blocks are welded to the first movable plate near the middle position. An internal threaded block is threaded to the outer side of the first bidirectional threaded rod. A rotating shaft is provided between the mounting blocks. Connecting plates are rotatably connected to both ends of the rotating shaft.

[0009] The auxiliary mechanism includes a side plate bolted to the side of the mounting frame near the stamping direction, and two sets of second movable plates slidably connected to the inner wall of the side plate.

[0010] Preferably, the positioning mechanism further includes two sets of limiting grooves opened on the inner wall of the stamping machine body, and the limiting grooves are close to both ends of the stamping machine body. A first drive motor is installed on one side of the stamping machine body, and a second drive motor is installed on one side of the mounting bracket. The connecting end of one end of the second drive motor is connected to the first bidirectional threaded rod. A guide rod is installed on the inner wall of each limiting groove. A second bidirectional threaded rod is provided on the lower side of the guide rod, and the connecting end of one side of the second bidirectional threaded rod is connected to the first drive motor.

[0011] Preferably, the bottom of the mounting bracket is slidably connected to the limiting groove, the guide rod passes through the bottom of the mounting bracket and is slidably connected to the mounting bracket, both ends of the bottom of the mounting bracket are L-shaped, the guide rod is located in the vertical direction of the L-shape of the mounting bracket, and the second bidirectional threaded rod is located in the vertical direction of the L-shape of the mounting bracket.

[0012] Preferably, the mounting block and the connecting plate are provided in two places, and are symmetrically arranged with the center point of the first movable plate as the axis. The other end of the connecting plate is rotatably connected to the internal thread block.

[0013] Preferably, the auxiliary mechanism further includes an upper sliding groove on the top wall of the side plate, and a lower sliding groove on the bottom of the side plate near the mounting bracket. An upper bidirectional threaded rod is provided inside the upper sliding groove, and a lower bidirectional threaded rod is provided inside the lower sliding groove. A third drive motor is installed at one end of each of the upper and lower bidirectional threaded rods.

[0014] Preferably, the upper bidirectional threaded rod passes through the top of the second movable plate and is threadedly connected to the top of the second movable plate, and the lower bidirectional threaded rod passes through the bottom of the second movable plate and is threadedly connected to the bottom of the second movable plate.

[0015] Preferably, the bottom of the second movable plate is concave, and the top and bottom of the second movable plate are respectively located on the inner walls of the upper sliding groove and the lower sliding groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The positioning device for stamping automotive parts is equipped with a positioning mechanism. The first bidirectional threaded rod is rotated by the second drive motor, so that the first movable plate can slide up and down on the inner wall of the mounting frame. It can quickly adjust to the appropriate height according to the processing parts of different thicknesses without manual fine adjustment.

[0018] When faced with plates of different widths, the third drive motor of the auxiliary mechanism is activated, which drives the upper and lower bidirectional threaded rods to rotate, thereby causing the two sets of second movable plates to slide along the upper and lower sliding grooves on the inner wall of the side plate.

[0019] The positioning mechanism works in conjunction with the auxiliary mechanism to flexibly adjust the distance between the two sets of movable plates, enabling all-round automated positioning and adjustment of the workpiece in terms of thickness, width, and lateral position, greatly enhancing the versatility of the device.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example

[0028] like Figure 1-3As shown, the device includes a stamping machine body 1. Positioning mechanisms 2 are provided on both sides of the stamping machine body 1. An auxiliary mechanism 3 is provided on the side of the positioning mechanism 2 closest to the stamping direction. The positioning mechanism 2 includes a mounting bracket 201 slidably connected to both sides of the stamping machine body 1. A first movable plate 202 is slidably connected to the inner wall of the mounting bracket 201. A first bidirectional threaded rod 203 is provided above the first movable plate 202. Two sets of mounting blocks 204 are welded to the first movable plate 202 near its center. An internal threaded block 205 is threadedly connected to the outer side of the first bidirectional threaded rod 203. A rotating shaft 206 is provided between the mounting blocks 204. The two ends of the rotating shaft 206 rotate... The positioning mechanism 2 is connected to the connecting plate 207. It also includes two sets of limiting grooves 208 opened on the inner wall of the stamping machine body 1. The limiting grooves 208 are close to both ends of the stamping machine body 1. A first drive motor 209 is installed on one side of the stamping machine body 1, and a second drive motor 210 is installed on one side of the mounting bracket 201. The connecting end of one end of the second drive motor 210 is connected to the first bidirectional threaded rod 203. Guide rods 211 are installed on the inner wall of the limiting grooves 208. A second bidirectional threaded rod 212 is provided on the lower side of the guide rod 211. The connecting end of one side of the second bidirectional threaded rod 212 is connected to the first drive motor 209.

[0029] It should be noted that, in this embodiment, the height of the first movable plate 202 is adjusted according to the thickness of the workpiece. First, the second drive motor 210 is started, and its connecting end drives the first bidirectional threaded rod 203 to rotate. The internal threaded block 205, which is threaded to the outer side of the first bidirectional threaded rod 203, will move on its outer side as the first bidirectional threaded rod 203 rotates. The movement of the internal threaded block 205 drives the mounting block 204 to move through the connecting plate 207 and the rotating shaft 206. Since the mounting block 204 is welded to the first movable plate 202, the first movable plate 202 will slide up and down on the inner wall of the mounting bracket 201 to realize the height adjustment of the first movable plate 202 to meet the positioning requirements of automotive parts of different thicknesses.

[0030] When adjusting the position of the mounting bracket 201, the first drive motor 209 is started first, and its connecting end drives the second bidirectional threaded rod 212 to rotate. Since the bottom of the mounting bracket 201 is slidably connected to the limiting groove 208, and the guide rod 211 passes through the bottom of the mounting bracket 201, and the second bidirectional threaded rod 212 is vertically engaged with the L-shaped bottom of the mounting bracket 201, the rotation of the second bidirectional threaded rod 212 will cause the mounting bracket 201 to slide along the guide rod 211 in the limiting groove 208, thereby realizing the position adjustment of the mounting bracket 201 on both sides of the stamping machine body 1 to adapt to automotive parts of different sizes.

[0031] like Figure 4 , 5As shown, the auxiliary mechanism 3 includes a side plate 301 bolted to the side of the mounting frame 201 near the stamping direction. Two sets of second movable plates 302 are slidably connected to the inner wall of the side plate 301. The auxiliary mechanism 3 also includes an upper sliding groove 303 opened on the top wall of the side plate 301 and a lower sliding groove 304 opened on the bottom of the side plate 301 near the mounting frame 201. An upper bidirectional threaded rod 305 is provided inside the upper sliding groove 303, and a lower bidirectional threaded rod 306 is provided inside the lower sliding groove 304. A third drive motor 307 is installed at the connection end of one end of the upper bidirectional threaded rod 305 and the lower bidirectional threaded rod 306.

[0032] It should be noted that in this embodiment, when dealing with automotive parts of different widths, the third drive motor 307 is activated, which drives the upper bidirectional threaded rod 305 and the lower bidirectional threaded rod 306 to rotate. The upper bidirectional threaded rod 305 passes through the top of the second movable plate 302 and is threadedly connected to the top of the second movable plate 302. The lower bidirectional threaded rod 306 passes through the bottom of the second movable plate 302 and is threadedly connected to the bottom of the second movable plate 302. As the upper bidirectional threaded rod 305 and the lower bidirectional threaded rod 306 rotate, the second movable plate 302 will slide along the upper sliding groove 303 and the lower sliding groove 304 on the inner wall of the side plate 301, thereby adjusting the distance between the two sets of second movable plates 302 and further positioning the automotive parts on the side closer to the stamping direction.

[0033] Once the positioning mechanism 2 and the auxiliary mechanism 3 have positioned the automotive parts, the stamping machine body 1 begins the stamping operation (the stamping process is conventional existing technology and will not be described in detail here), thus completing the stamping processing of the automotive parts.

[0034] Furthermore, the first drive motor 209, the second drive motor 210, and the third drive motor 307 all have braking functions. When the first drive motor 209, the second drive motor 210, and the third drive motor 307 stop working, the braking mechanism inside the motor will fix the motor shaft (given that this type of motor braking technology has been used in the industrial field for a long time and has a high degree of technical maturity, the specific implementation of the braking mechanism will not be described in detail here) to prevent it from rotating, so that the three sets of bidirectional threaded rods connected to the motor shaft cannot rotate on their own after the motor stops, thereby achieving position locking.

[0035] Working principle of this utility model:

[0036] Refer to the instruction manual appendix Figure 1-5The height of the first movable plate 202 is adjusted according to the thickness of the workpiece. First, the second drive motor 210 is started, and its connecting end drives the first bidirectional threaded rod 203 to rotate. The internal threaded block 205 connected to the outer thread of the first bidirectional threaded rod 203 will move on its outer side as the first bidirectional threaded rod 203 rotates. The movement of the internal threaded block 205 drives the mounting block 204 to move through the connecting plate 207 and the rotating shaft 206. Since the mounting block 204 is welded to the first movable plate 202, the first movable plate 202 will slide up and down on the inner wall of the mounting frame 201 to realize the height adjustment of the first movable plate 202 to meet the positioning requirements of automotive parts of different thicknesses.

[0037] When adjusting the position of the mounting bracket 201, the first drive motor 209 is started first, and its connecting end drives the second bidirectional threaded rod 212 to rotate. Since the bottom of the mounting bracket 201 is slidably connected to the limiting groove 208, and the guide rod 211 passes through the bottom of the mounting bracket 201, and the second bidirectional threaded rod 212 is vertically engaged with the L-shaped bottom of the mounting bracket 201, the rotation of the second bidirectional threaded rod 212 will cause the mounting bracket 201 to slide along the guide rod 211 in the limiting groove 208, thereby realizing the position adjustment of the mounting bracket 201 on both sides of the stamping machine body 1 to adapt to automotive parts of different sizes;

[0038] When dealing with automotive parts of different widths, the third drive motor 307 is activated, which drives the upper bidirectional threaded rod 305 and the lower bidirectional threaded rod 306 to rotate. The upper bidirectional threaded rod 305 passes through the top of the second movable plate 302 and is threadedly connected to the top of the second movable plate 302. The lower bidirectional threaded rod 306 passes through the bottom of the second movable plate 302 and is threadedly connected to the bottom of the second movable plate 302. As the upper bidirectional threaded rod 305 and the lower bidirectional threaded rod 306 rotate, the second movable plate 302 slides along the upper sliding groove 303 and the lower sliding groove 304 on the inner wall of the side plate 301, thereby adjusting the distance between the two sets of second movable plates 302 and further positioning the automotive parts on the side closer to the stamping direction.

[0039] After the positioning mechanism 2 and the auxiliary mechanism 3 have positioned the automotive parts, the stamping machine body 1 begins the stamping operation to complete the stamping process of the automotive parts.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
