Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, and in particular to a plastic product clamping fixture. Background Technology

[0002] Plastic is a synthetic polymer material made from synthetic resins. It is produced by adding plasticizers, stabilizers, and colorants as auxiliary materials and then processing them under specific temperatures and pressures through injection molding, blow molding, calendering, and cooling molding processes. Plastics have a wide range of applications, including industrial fields, daily life, medical equipment, and aerospace. In the production of plastic products, clamping fixtures are needed to improve the stability of the plastic products and facilitate their processing.

[0003] A search revealed that Chinese Patent CN222449957U discloses a clamping fixture for plastic products, including a base and a supporting vertical plate. A vertical slide rod is movably mounted on the upper end of the supporting vertical plate, and a horizontal support cylinder is inserted into the right end of the vertical slide rod. An electric telescopic rod for adjusting the horizontal extension length and a transmission gear helical wheel for transmitting power are installed on the side of the horizontal support cylinder. A set of outer arc-shaped top plates are fixedly connected to the end of the outward expansion top rod away from the support cylinder. A set of rotating rollers are movably mounted on the front and rear sides of the outer arc-shaped top plates, and a set of rubber sleeves are fixedly fitted on the outer surface of each roller. By setting up the horizontal support cylinder, the entire plastic product is clamped from the inner hole, facilitating the operator to perform processing on the outside of the plastic product. By setting up the clamping mechanism, the outward expansion top rod is caused to move outward under the limit of the slide groove of the support cylinder. The outwardly moving outward expansion top rod squeezes and holds the plastic product from the inner cavity, thereby clamping the plastic product from the inner cavity.

[0004] The above-mentioned technical solution can only fix and clamp a part of the plastic product. It cannot quickly adjust the clamping part on the plastic product, which can easily lead to the problem of inconvenience in processing different parts of the plastic product. It is not conducive to improving the flexibility of practical use. At the same time, it cannot provide better support for plastic products of different diameters. It is easy to cause the plastic product to tilt due to the small support point, which is not conducive to improving the stability of clamping. Utility Model Content

[0005] The above-mentioned technical solutions only fix and clamp a part of the plastic product, and cannot quickly adjust the clamping part on the plastic product. This makes it inconvenient to process different parts of the plastic product, which is not conducive to improving the flexibility of use. At the same time, it cannot provide better support for plastic products of different diameters, which can easily lead to the plastic product tilting due to the small support point, which is not conducive to improving the stability of clamping. Therefore, this utility model provides a plastic product clamping fixture.

[0006] The technical solution adopted by this utility model is: a clamping fixture for plastic products, comprising:

[0008] A clamping and adjusting assembly is mounted on the push plate and is used to clamp plastic products. The clamping and adjusting assembly includes symmetrically arranged clamping structures, each including a self-locking motor and symmetrically arranged horizontal plates. The self-locking motor is fixedly mounted on the push plate, and the horizontal plates are fixedly connected to the push plate. Symmetrically arranged rollers are rotatably mounted on the horizontal plates, and rollers are fixedly mounted on the rollers. The rollers are fixedly connected to the output shaft of the self-locking motor, and belts are fitted onto the rollers.

[0009] Furthermore, a power assembly is installed below the push plate, which is used to drive the push plate to move.

[0010] Furthermore, the power assembly includes a bidirectional linear cylinder, the telescopic end of which is fixedly equipped with a support rod, the support rod being fixedly connected to the push plate, and a limiting block being fixedly installed on the side wall of the support rod.

[0011] Furthermore, a support assembly is installed below the bidirectional linear cylinder, which is used to support the plastic product.

[0012] Furthermore, the support assembly includes a one-way linear cylinder, a lifting plate is fixedly installed above the telescopic end of the one-way linear cylinder, a support plate is fixedly installed above the lifting plate, and the support plate is located between the symmetrically installed clamping structures.

[0013] Furthermore, a processing table is installed below the push plate, and a sliding groove is formed in the middle of the processing table. A slider is fixedly installed below the push plate and is slidably installed in the sliding groove. The clamping and adjusting assembly is located below the processing table. The fixed end of the bidirectional linear cylinder is fixedly installed below the processing table. The support rod and the limiting block slide through the sliding groove. The fixed end of the unidirectional linear cylinder is fixedly connected to the processing table. A through hole is formed on the processing table, and the support plate slides through the through hole.

[0014] The beneficial effects of this utility model are:

[0024] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0025] In order to solve the problems existing in the background art, this application proposes the following technical solution: a clamping fixture for plastic products.

[0026] The specific technical solution includes a symmetrically installed push plate 1 and a clamping and adjusting assembly 2;

[0027] like Figure 1 and Figure 4 As shown, the clamping and adjusting assembly 2 is mounted on the push plate 1. The clamping and adjusting assembly 2 is used to clamp plastic products. The clamping and adjusting assembly 2 includes symmetrically arranged clamping structures, including a self-locking motor 201 and symmetrically arranged horizontal plates 202. The self-locking motor 201 can drive the rollers 204 connected to it to rotate. The horizontal plates 202 can support the rollers 203. The self-locking motor 201 is fixedly mounted on the push plate 1. The horizontal plates 202 are fixedly connected to the push plate 1. The symmetrically arranged rollers 203 are rotatably mounted on the horizontal plates 202. The rollers 203 can clamp and fix the plastic products. The rollers 204 are fixedly mounted on the rollers 203. The rollers 204 can support the belt 205. The rollers 204 are fixedly connected to the output shaft of the self-locking motor 201. The belt 205 is sleeved on the rollers 204. The belt 205 can drive the two rollers 204 on the same push plate 1 to rotate synchronously.

[0028] There are two push plates 1. Each push plate 1 is equipped with a self-locking motor 201, two horizontally arranged plates 202, two horizontally arranged rollers 203, two horizontally arranged wheels 204, and a belt 205. Figure 4 As shown, a plastic product is clamped between two push plates 1, with the product positioned between rollers 203 on the two push plates 1 and horizontally placed above two support plates 403. The rollers 203 on both sides can clamp and fix the plastic product, facilitating its processing. By simultaneously and in opposite directions activating the self-locking motors 201 on both sides, the left self-locking motor 201 rotates clockwise and the right self-locking motor 201 rotates counterclockwise. The self-locking motors 201 can drive the connected rollers 204 to rotate, which in turn drives the belt 205 to rotate. The belt 205 then drives another roller within the belt 205 to rotate. When one roller 204 rotates, the two rollers 204 within the same belt 205 can rotate synchronously. Therefore, the roller 204 on the left push plate 1 is driven to rotate clockwise by the left self-locking motor 201, and the roller 204 on the right push plate 1 is driven to rotate counterclockwise by the right self-locking motor 201. The roller 204 on the left push plate 1 drives the roller 203 connected to it to rotate clockwise, and the roller 204 on the right push plate 1 drives the roller 203 connected to it to rotate counterclockwise. The rollers 203 on both sides can move the plastic product to the right and then stop clamping and fixing it, thus changing the position of clamping and fixing the plastic product.

[0029] like Figure 2 and Figure 4As shown, a power assembly 3 is installed below the push plate 1. The power assembly 3 is used to drive the push plate 1 to move. The power assembly 3 includes a bidirectional linear cylinder 301. The bidirectional linear cylinder 301 can drive the support rod 302 to move. The extension end of the bidirectional linear cylinder 301 is fixedly equipped with the support rod 302. The support rod 302 can drive the push plate 1 to move. The support rod 302 is fixedly connected to the push plate 1. A limiting block 303 is fixedly installed on the side wall of the support rod 302. The limiting block 303 can improve the stability of the movement of the support rod 302.

[0030] By activating the bidirectional linear cylinder 301, the support rods 302 on both sides move. The support rods 302 on both sides drive the limiting block 303 to slide in the slide groove 6. The support rods 302 can drive the push plate 1 to move. The push plates 1 on both sides can move closer or further apart. The push plate 1 can drive the self-locking motor 201 and the horizontal plate 202 to move. The self-locking motor 201 and the horizontal plate 202 can drive the roller 204 and the roller shaft 203 to move. The roller 204 can drive the belt 205 to move. It can drive the roller shafts 203 on both sides to move closer or further apart. It can clamp and fix the plastic products between the roller shafts 203 on both sides and make it easy to replace the plastic products.

[0031] like Figure 3-4 As shown, a support assembly 4 is installed below the bidirectional linear cylinder 301. The support assembly 4 is used to support the plastic product. The support assembly 4 includes a unidirectional linear cylinder 401. The unidirectional linear cylinder 401 can drive the lifting plate 402 to rise and fall. The lifting plate 402 is fixedly installed above the telescopic end of the unidirectional linear cylinder 401. The lifting plate 402 can support the support plate 403. The support plate 403 is fixedly installed above the lifting plate 402. The support plate 403 can support the plastic product. The support plate 403 is located between the symmetrically installed clamping structures.

[0032] After the plastic product is clamped between the rollers 203 on both sides, the lifting plate 402 is raised by activating the one-way linear cylinder 401. The lifting plate 402 can raise the support plate 403, which can support the bottom of the plastic product clamped between the rollers 203 on both sides, which can help improve the stability of the plastic product. The distance between the two support plates 403 can be set according to actual needs.

[0033] like Figure 1 and Figure 4As shown, a processing table 5 is installed below the push plate 1. The processing table 5 can conveniently place plastic products. A slide groove 6 is opened in the middle part of the processing table 5. The slide groove 6 can limit the movement path of the support rod 302, the limiting block 303 and the slider 7, which helps to improve the stability of the movement of the support rod 302, the limiting block 303 and the slider 7. A slider 7 is fixedly installed below the push plate 1. The slider 7 is slidably installed in the slide groove 6. The clamping and adjusting component 2 is located below the processing table 5. The fixed end of the bidirectional linear cylinder 301 is fixedly installed below the processing table 5. The support rod 302 and the limiting block 303 slide through the slide groove 6. The fixed end of the unidirectional linear cylinder 401 is fixedly connected to the processing table 5. The processing table 5 can fix the fixed ends of the bidirectional linear cylinder 301 and the unidirectional linear cylinder 401. A through hole 8 is opened on the processing table 5. The through hole 8 can conveniently improve the stability of the lifting and lowering of the support plate 403. The support plate 403 slides through the through hole 8.
