Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to a plastic welding clamp. Background Technology

[0002] A fixture is a mechanical device used to fix workpieces during the manufacturing process. It is mainly used for plastic welding and is quite common in existing technology.

[0003] Existing technologies, such as the utility model patent with publication number CN206690575U, disclose a plastic pipe welding fixture. This patent uses a plastic pipe with a tube body boss surface adapted to the welding surface of the plastic part to be welded. The welding fixture includes a fixture body, clamping blocks on both sides of the fixture body for clamping the plastic pipe, and a position adjustment block at the upper end of the fixture body. The upper ends of the clamping blocks are located on both sides of the tube body boss surface. The side of the clamping block that contacts the plastic pipe has a first curved groove that fits with the outer arc surface of the plastic pipe, and the side of the position adjustment block that is opposite to the plastic pipe has a second curved groove. The first curved groove protrudes upward from the second curved groove. The upper end of the position adjustment block protrudes upward from the upper end of the tube body boss surface. The gap between the position adjustment block and the side of the tube body boss surface solves the problem that the clamping part of the fixture does not constrain the two mold surfaces. After the tube body boss surface and the welding surface of the part to be welded come into contact, molten water overflows freely, resulting in serious overflow and unsightly weld surface.

[0004] The inventors discovered in their daily work that when using clamps to fix plastic parts, existing clamps can only hold and fix plastic parts of one size. When other sizes of plastic parts need to be held and fixed, personnel can only change the clamps to hold and fix the plastic parts of other sizes. This operation is too cumbersome, which leads to a decrease in the work efficiency of personnel.

[0005] Therefore, it is necessary to provide a new type of plastic welding fixture to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a plastic welding fixture.

[0007] To solve the above technical problems, this utility model provides a plastic welding fixture, including: a base plate and a plastic part. The upper surface of the base plate is provided with a fixing structure, which includes a positioning plate. The positioning plate is fixedly connected to the base plate. A fixing plate, two telescopic rods, and a cylinder are fixedly connected to the upper surface of the positioning plate. A movable plate is fixedly connected to the end of the two telescopic rods away from the positioning plate. The movable plate is fixedly connected to the output end of the cylinder. Two connecting grooves are formed in the inner wall of the movable plate. A movable block is slidably connected to the inner wall of the connecting groove. A lead screw is rotatably connected to the inner wall of the connecting groove. The lead screw is rotatably connected to the movable plate. A connecting plate is fixedly connected to the upper surface of the movable block. Several top blocks are fixedly connected to the upper surface of the connecting plate. The top blocks are trapezoidal. Two sliding grooves are formed in the inner wall of the fixing plate. An adjusting block is slidably connected to the inner wall of the sliding groove. A pressing plate is fixedly connected to the side of the adjusting block away from the base plate. A connecting block is fixedly connected to the side of the adjusting block away from the pressing plate. The connecting block is trapezoidal.

[0008] The effect achieved by the above-mentioned components is as follows: When personnel need to fix plastic parts of other sizes, this type of clamp can only clamp and fix plastic parts of one size. When personnel need to clamp and fix plastic parts of other sizes, they can only do so by changing the clamp. This operation is too cumbersome, which leads to low work efficiency. This problem can be solved by the fixing structure. By setting up the fixing structure, personnel can place plastic parts of different sizes in the middle position above the fixing plate. Then, personnel will press the two extrusion plates against the plastic parts, and finally, by activating the cylinder, the two extrusion plates will press and fix the plastic parts. This allows for the clamping and fixing of plastic parts of different sizes, increases the applicability of the clamp, and improves the work efficiency of personnel.

[0009] Preferably, a rotating rod is fixedly connected to the inner wall of the lead screw, and the rotating rod has a circular cross-section.

[0010] The effect achieved by the above components is that the rotating rod makes it easier for personnel to rotate the lead screw, thereby improving the ease of operation.

[0011] Preferably, the arc surface of the rotating rod is fixedly connected to two anti-slip sleeves, and the cross-section of the anti-slip sleeves is hollow circle.

[0012] The effect achieved by the above components is that the anti-slip sleeve can increase the friction between the operator's hand and the rotating rod, and can prevent the operator from slipping during the rotation of the rotating rod.

[0013] Preferably, the inner wall of the chute is fixedly connected to two limiting rods, and the two limiting rods are slidably connected to the adjusting block.

[0014] The effect achieved by the above components is that the limiting rod can limit the movement of the moving block and prevent the moving block from becoming misaligned during the sliding process on the inner wall of the groove.

[0015] Preferably, protective pads are uniformly fixedly connected to the sides of the two extrusion plates that are close to each other, and the two protective pads abut against the plastic parts.

[0016] The effect achieved by the above components is that the protective pad can protect the plastic parts and prevent the plastic parts from coming into direct contact with the extrusion plate.

[0017] Preferably, the movable plate is a stainless steel plate.

[0018] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the moving plate from deforming during short-term use.

[0019] Compared with related technologies, the plastic welding fixture provided by this utility model has the following beneficial effects:

[0020] By setting up a fixing structure, when personnel need to clamp and fix plastic parts of different sizes, the fixing structure can facilitate the clamping and fixing of round plastic parts of different sizes, thereby improving the work efficiency of personnel. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figure 1 The present invention provides a plastic welding fixture, comprising: a base plate 1 and a plastic part 2, wherein a fixing structure 3 is provided on the upper surface of the base plate 1.

[0029] In the embodiments of this utility model, please refer to Figures 2 to 4The fixed structure 3 includes a positioning plate 301, which is fixedly connected to the base plate 1. A fixing plate 304, two telescopic rods 302, and a cylinder 303 are fixedly connected to the upper surface of the positioning plate 301. A movable plate 305 is fixedly connected to the end of each of the two telescopic rods 302 away from the positioning plate 301. The movable plate 305 is fixedly connected to the output end of the cylinder 303. Two connecting grooves 306 are formed on the inner wall of the movable plate 305. A movable block 307 is slidably connected to the inner wall of the connecting groove 306. A lead screw 30 is rotatably connected to the inner wall of the connecting groove 306. 8. The lead screw 308 is rotatably connected to the moving plate 305. The upper surface of the moving block 307 is fixedly connected to the connecting plate 311. Several top blocks 312 are fixedly connected to the upper surface of the connecting plate 311. The top blocks 312 are trapezoidal. The inner wall of the fixed plate 304 has two sliding grooves 313. The inner wall of the sliding grooves 313 is slidably connected to the adjusting block 315. The side of the adjusting block 315 away from the bottom plate 1 is fixedly connected to the pressing plate 316. The side of the adjusting block 315 away from the pressing plate 316 is fixedly connected to the connecting block 318. The connecting block 318 is trapezoidal. When personnel need to fix plastic parts 2 of other sizes, since this clamp can only clamp and fix plastic parts 2 of one size, when personnel need to clamp and fix plastic parts 2 of other sizes, they can only do so by changing the clamp. This operation is too cumbersome, which leads to low work efficiency. At this time, the fixing structure 3 can solve this problem. By setting the fixing structure 3, personnel can place plastic parts 2 of different sizes in the middle position above the fixing plate 304. Then, personnel will press the two extrusion plates 316 against the plastic parts 2. Finally, by activating the cylinder 303, the two extrusion plates 316 will press and fix the plastic parts 2. This allows for the clamping and fixing of plastic parts 2 of different sizes, increasing the applicability of the clamp and improving the work efficiency of personnel. The inner wall of the lead screw 308 is fixedly connected to the rotating rod 309, and the cross-section of the rotating rod 309 is circular. The rotating rod 309 facilitates the rotation of the lead screw 308, improving operational convenience. Two anti-slip sleeves 310 are fixedly connected to the arc surface of the rotating rod 309; the anti-slip sleeves 310 have a hollow circular cross-section. The anti-slip sleeves 310 increase the friction between the operator's hand and the rotating rod 309, preventing slippage during rotation. Two limiting rods 314 are fixedly connected to the inner wall of the slide groove 313, and these limiting rods 314 are slidably connected to the adjusting block 315. The limiting rods 314 limit the movement block 307, preventing misalignment during sliding along the inner wall of the slide groove 313. Protective pads 317 are evenly fixedly connected to the sides of the two pressing plates 316 that are close to each other, and these protective pads 317 abut against the plastic part 2. The protective pads 317 protect the plastic part 2, preventing direct contact between it and the pressing plates 316. The moving plate 305 is made of stainless steel.Stainless steel plates have high strength and good wear resistance, which can prevent deformation of the moving plate 305 during short-term use.

[0030] The working principle of the plastic welding fixture provided by this utility model is as follows: When a person needs to fix the plastic part 2, the person can first place the plastic part 2 in the middle position on the upper surface of the fixing plate 304, and then move the two extrusion plates 316, so that the two extrusion plates 316 move closer to the plastic part 2. The extrusion plates 316 drive the protective pad 317 and the adjusting block 315 to move closer to the plastic part 2. The protective pad 317 can protect the plastic part 2 and prevent the plastic part 2 from directly contacting the extrusion plate 316. Then the adjusting block 315 moves along the arc surface of the two limiting rods 314. The sliding mechanism is as follows: the limiting rod 314 can limit the movement of the moving block 307, preventing misalignment during sliding on the inner wall of the slide groove 313. The adjusting block 315 drives the connecting block 318 to move closer to the plastic part 2 until the two protective pads 317 abut against the plastic part 2. Then, the cylinder 303 is activated. The output end of the cylinder 303 drives the moving plate 305 to move upward. The moving plate 305 drives the output ends of the two telescopic rods 302, the two lead screws 308, and the two moving blocks 307 to move upward. The lead screws 308 drive the rotating rod 309 to move upward. 09 allows for easy rotation of the lead screw 308, improving operational convenience. The rotating rod 309 then moves two anti-slip sleeves 310 upwards. These sleeves increase friction between the operator's hand and the rotating rod 309, preventing slippage during rotation. The moving block 307 then moves the connecting plate 311 upwards, which in turn moves several top blocks 312 upwards until the inclined surfaces of the top blocks 312 abut against the inclined surfaces of the connecting block 318. This causes the connecting block 318 to move closer to the plastic part 2, thus protecting the two... The pad 317 abuts against the plastic part 2. When it is found that one of the connecting blocks 318 and the top block 312 are squeezed too loosely, the operator can rotate the rotating rod 309 before the top block 312 moves upward. The rotating rod 309 drives the lead screw 308 to rotate, the lead screw 308 drives the moving block 307 to move, the moving block 307 drives the connecting plate 311 to move, and the connecting plate 311 drives several top blocks 312 to move, thereby making a fine adjustment to the top block 312. The moving plate 305 is a stainless steel plate. Stainless steel plate has high strength and good wear resistance, which can prevent the moving plate 305 from deforming during short-term use.
