Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of plastic product processing equipment, and in particular relates to a clamping device for processing plastic products. Background Technology
[0002] In the production of plastic products, it is not only necessary to melt, cast, shape and cool the plastic raw materials, but also to carry out fine processing, such as painting, spraying, engraving and polishing. One of the most common processing devices in the fine processing of plastic products is the clamping device, which is used to hold the plastic products to make them easier to handle in subsequent operations.
[0003] A Chinese patent application (or patent) with publication number CN221774322U discloses a clamping fixture for plastic products, including a base and clamping blocks one and two symmetrically arranged above the base. Both clamping blocks one and two have arc-shaped clamping grooves on their adjacent sides, and connecting members one and two are respectively provided on their distant sides. Connecting members one and two are connected to the base via a clamping assembly. The beneficial effect is that through the cooperative design of clamping blocks one and two, connecting members one and two, and the clamping assembly, when clamping blocks one and two are pressed inwards and installed on the outside of the plastic product, they compress and confine the plastic product, thereby increasing the contact surface of the equipment and preventing loosening during clamping.
[0004] The aforementioned clamping fixture for plastic products includes a base on which clamping blocks, an electric push rod, and a triangular connecting piece are mounted to clamp the plastic product. However, plastic products are often processed on multiple sides, requiring rotation for changing surfaces. This device only clamps the product; rotation can only be achieved by repeatedly disassembling and reassembling the product or by manually moving, flipping, or rotating the clamping device, causing inconvenience. Furthermore, the fixture uses clamping blocks one and two, each with an arc-shaped groove on one side. This means the most effective clamping is for products with arc-shaped surfaces. However, plastic products come in various shapes, and the clamping effect of the rigid material clamping blocks one and two is limited. Therefore, we provide a clamping device for processing plastic products to solve the aforementioned problems. Utility Model Content
[0005] The purpose of this utility model is to provide a clamping device for processing plastic products. By utilizing the rotating component in the base, the clamping frame, clamping component, and plastic product on its shaft end can be rotated at a certain angle, which facilitates the adjustment of the processing surface of the plastic product. By utilizing the clamping sleeve, rubber suction cup, and air pump in the clamping component, it can effectively clamp plastic products with smooth outer walls, thus solving the problems of the aforementioned plastic product clamping fixture.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a clamping device for processing plastic products, comprising a base; an equipment slot is provided in the base, and a rotating assembly is installed in the equipment slot. The rotating assembly includes a stepper motor fixedly installed in the equipment slot, and a rotating shaft is synchronously connected to the shaft end of the stepper motor. A clamping frame is also fixedly installed at the top end of the rotating shaft. Clamping components are also provided at both ends of the clamping frame. The clamping component includes a pneumatic rod embedded in the clamping frame, and a clamping sleeve is detachably fixedly installed on the outer wall of the shaft end of the pneumatic rod. A rubber suction cup is embedded in the outer wall of the clamping sleeve, and the rubber suction cup is connected to an air pump through a rubber hose.
[0008] The present invention is further configured such that the equipment slot is fixedly connected to the motor frame by bolts, and the stepper motor is also fixedly installed inside the motor frame, and a cover plate slot is provided on the top of the equipment slot.
[0009] The present invention is further configured such that the cover plate groove is connected to the sealing plate by bolts, the sealing plate is arranged in a ring structure, and an auxiliary ring is snapped on the inner wall of the inner ring of the sealing plate, and the sealing plate is clearance-fitted with the outer wall of the motor shaft of the stepper motor through the auxiliary ring.
[0010] The present invention is further configured such that a shaft groove is provided on the outer wall of the shaft end of the stepper motor, and the stepper motor is engaged with the connecting plate through the shaft groove on the shaft end, and the connecting plate is welded to the bottom side wall of the rotating shaft.
[0011] The present invention is further configured such that the clamping frame is U-shaped, and a connecting sleeve is welded at the center of the bottom side wall of the clamping frame, and the clamping frame is threadedly connected to the top side wall of the rotating shaft through the connecting sleeve.
[0012] The present invention is further configured such that mounting holes are provided in both end side walls of the clamping frame, and a tube groove is provided above the mounting holes. A rod frame is provided inside the mounting holes, and the clamping frame is connected to a pneumatic rod through the rod frame.
[0013] The present invention is further configured such that a rubber hose is inserted into the groove, one end of the rubber hose is connected to the suction tube through a solenoid valve, and the other end of the rubber hose is also connected to a multi-pipe connector, which is also connected to the air nozzle of the air pump.
[0014] The present invention is further configured such that the suction tube passes through the side wall of the clamping sleeve and is connected to the rubber suction cup, and a fixing frame is also snapped onto the outside of the air pump, and the air pump is fixedly installed on the bottom side wall of the clamping frame by the fixing frame.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model sets up a base and a rotating component. The rotating component is set on the base. By using the stepper motor in the rotating component, the rotating column on its shaft end can be rotated at a certain angle. When the rotating column rotates, the clamping frame, clamping component and the clamped plastic product on its top shaft end also rotate. This allows the processing surface of the plastic product to be adjusted, which is convenient for the operator to continuously process the plastic product on the clamping frame.

It is applicable to various plastic products with smooth outer walls and different shapes.

Detailed Implementation
[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] Please see Figure 1-3 This utility model is a clamping device for processing plastic products, including a base 1 and a rotating component 2 thereon. The stepper motor 201 in the rotating component 2 can drive the rotating shaft 203 on its shaft end to rotate at a certain angle. When the rotating shaft 203 rotates, the clamping frame 3 on it also rotates, so as to adjust the processing surface of the plastic product clamped in the clamping frame 3.
[0030] Specifically, the base 1 has a device slot 101 for mounting the stepper motor 201 in the rotating assembly 2. The top of the device slot 101 also has a cover slot 102 for covering the sealing plate 103. An auxiliary ring 104 is also embedded on the sealing plate 103. The sealing plate 103 is in clearance fit with the rotating shaft 203 through the auxiliary ring 104, and the rotating shaft 203 is set on the motor shaft of the stepper motor 201.
[0031] Furthermore, the outer wall of the motor shaft end of the stepper motor 201 is provided with a shaft groove 201a that mates with the connecting plate 203a. The connecting plate 203a is welded to the bottom of the rotating shaft 203 and is fixed in the shaft groove 201a by bolts. The equipment slot 101 is connected to the motor frame 202 by bolts, and the stepper motor 201 is fixedly installed in the motor frame 202.
[0032] The operation process of this embodiment is as follows: When in use, the stepper motor 201 works, and the rotating shaft 203 on its shaft end also rotates. Since the clamping frame 3 and the plastic product clamped on the clamping frame 3 also rotate, the processing surface of the clamped plastic product is adjusted.
[0033] Example 2
[0034] Please see Figure 4-5 Based on embodiment 1, a clamping frame 3 and clamping components 4 at both ends are also provided. By using the pneumatic rod 401, the clamping sleeve 402 on its shaft end can be pressed against the outer wall of the plastic product by the rubber suction cup 403. Then, under the negative pressure supply of the air pump 406, the rubber suction cup 403 generates an adsorption force on the plastic product, improving the stability of the clamping effect. It can also be applied to various plastic products with smooth outer walls of different shapes.
[0035] Specifically, the inner walls of the left and right ends of the clamping frame 3 are provided with mounting holes 302 for mounting the rod frame 401a in the clamping assembly 4, and the clamping frame 3 is connected to the pneumatic rod 401 through the rod frame 401a. The shaft end of the pneumatic rod 401 is also detachably fixed with a clamping sleeve 402. A rubber suction cup 403 is embedded in the outer wall of the clamping sleeve 402, and the rubber suction cup 403 is connected to the air pump 406 through a rubber hose 404.
[0036] Furthermore, a connecting sleeve 301 is welded to the bottom side wall of the clamping frame 3, and the connecting sleeve 301 is threaded to the shaft end of the rotating shaft 203. A tube groove 303 is opened above the mounting hole 302, and a rubber hose 404 is inserted in the tube groove 303. One end of the rubber hose 404 is connected to the suction tube 403a through a solenoid valve 403b, and the other end of the rubber hose 404 is connected to the air pump 406 through a multi-pipe connector 405. The suction tube 403a passes through the clamping sleeve 402 and is connected to the rubber suction cup 403. The air pump 406 is fixedly installed on the bottom side wall of the clamping frame 3 by a fixing bracket 406a.
[0037] The operation process of this embodiment is as follows: When in use, the smooth side of the plastic product to be clamped faces the side where the clamping assembly 4 is located, and the plastic product is placed on the clamping frame 3. Then, the pneumatic rod 401 is activated. When the pneumatic rod 401 is working, it extends and drives the clamping sleeve 402 on the shaft end to gradually approach the plastic product and abut against its outer wall through the rubber suction cup 403. After the abutment is completed, the air pump 406 works and generates negative pressure. This negative pressure is transmitted to the rubber suction cup 403 through the rubber hose 404, the suction tube 403a and the solenoid valve 403b. At the same time, because the rubber suction cup 403 is in direct contact with the outer wall of the plastic product, it can form an adsorption force on the outer wall of the plastic product, thereby improving the stability of clamping.
