Description

Technical Field

[0001] This utility model relates to the field of plastic parts clamping, and more particularly to a clamping mechanism for processing plastic parts. Background Technology

[0002] Plastic part clamping is a key method for positioning and fixing plastic parts during the processing of plastic parts, using specific mechanical structures and operating methods.

[0003] Existing technology, Chinese Patent Publication No. CN222450042U, discloses a clamping fixture for processing plastic parts, comprising: a fixed plate, a slide plate, a threaded rod, and a motor. The motor is mounted on one side of the fixed plate, and two slide plates are fixedly mounted between the two fixed plates. The output ends of the two motors are fixedly connected to threaded rods, and each of the two threaded rods is provided with a clamping assembly. The clamping assembly includes a rotating block, a handle, a rotating column, and a slider. The advantages are: the handle can be rotated to change the clamping block according to different plastic products, allowing for the selection of suitable clamping blocks. Therefore, the same clamping device can clamp multiple plastic products, eliminating the need for frequent changes of the clamping device when dealing with multiple plastic products; simply rotating the handle to change the clamping block simplifies the work process.

[0004] Traditional clamping methods focus only on clamping and fixing plastic parts in a single direction. This results in a lack of effective restraint on the sidewalls when the plastic parts are subjected to clamping forces and external forces generated during subsequent processing. This makes it easy for the plastic parts to shift, shake, or even tip over, making it difficult to guarantee processing accuracy. To address this issue, a clamping and holding mechanism for processing plastic parts is proposed. Utility Model Content

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.

[0031] Reference Figure 1 , Figure 3 , Figure 4The present invention provides an embodiment of a clamping mechanism for processing plastic parts, comprising a support base 1, a support mechanism 2 and an adjustment mechanism 3 on the top of the support base 1, the support mechanism 2 including a fixed seat 211 fixedly connected to the top of the support base 1 for fixing a rotating rod 212 and allowing it to rotate therein, the rotating rod 212 being rotatably connected to the inner wall of the fixed seat 211, the rotating rod 212 being rotatable within the fixed seat 211, a clamping handle 213 fixedly connected to the outer wall of the rotating rod 212, rotating the clamping handle 213 to drive the rotating rod 212 to rotate, a connecting plate 214 rotatably connected to the outer wall of the rotating rod 212, a support plate 215 fixedly connected to the bottom of the connecting plate 214, a clamping head 216 fixedly connected to the bottom of the support plate 215, the support plate 215 driving the clamping head 216 to clamp the plastic part, and a helical gear 21 fixedly connected to the outer wall of the rotating rod 212. 7. When the rotating rod 212 rotates, it drives the helical gear 217 to rotate. The helical gear 217 is meshed with the helical gear 218. The rotation of the helical gear 217 drives the rotation of the helical gear 218. The inner wall of the helical gear 218 is fixedly connected to the rotating rod 219. The rotation of the helical gear 218 drives the rotation of the rotating rod 219. The bottom end of the rotating rod 219 is rotatably connected to the top of the support base 1, providing support and a base for rotation. The outer wall of the rotating rod 219 is fixedly connected to the spur gear 220. The rotation of the rotating rod 219 drives the spur gear 220 to rotate. The outer wall of the spur gear 220 is meshed with the toothed plate 221. The rotation of the spur gear 220 drives the toothed plate 221 to move. The outer wall of the toothed plate 221 is slidably connected to the top of the support base 1, so that the toothed plate 221 can slide smoothly on the support base 1. The top of the support base 1 is slidably connected to the moving block 222, which moves with the movement of the toothed plate 221.

[0032] Reference Figure 1 , Figure 3 , Figure 4The support mechanism 2 also includes a clamping plate 223, the bottom of which contacts the top of the movable block 222. The clamping plate 223 is used to clamp and support the side wall of the plastic part. The side wall of the movable block 222 is fixedly connected to the outer wall of the toothed plate 221. The movable block 222 moves with the toothed plate 221, thereby driving the clamping plate 223 to move. The support mechanism 2 also includes a screw 224, the outer wall of which is rotatably connected to the inner wall of the movable block 222, and the outer wall of which is slidably connected to the inner wall of the support base 1. The support mechanism 2 also includes a screw hole block 225. The outer wall of the screw hole block 225 is slidably connected to the top of the movable block 222. The screw hole block 225 can slide on the top of the movable block 222. The top of the screw hole block 225 is fixedly connected to the bottom of the clamping plate 223. The screw hole block 225 drives the clamping plate 223 to move. The inner wall of the screw hole block 225 is threadedly connected to the outer wall of the screw rod 224. When the screw rod 224 rotates, it drives the screw hole block 225 to move. The support mechanism 2 also includes a torsion block 226. The outer wall of the torsion block 226 is fixedly connected to the end of the screw rod 224 away from the clamping plate 223. Rotating the torsion block 226 can drive the screw rod 224 to rotate.

[0033] Reference Figure 1 , Figure 2 The adjustment mechanism 3 includes a lifting groove 311, which is located on the top of the support base 1 and is used to accommodate the pad 312 and provide it with lifting space. The pad 312 is slidably connected to the inner wall of the lifting groove 311 and can slide up and down in the lifting groove 311. The adjustment mechanism 3 also includes a screw 313, the outer wall of which is threaded to the inner wall of the support base 1. The screw 313 can be lifted when it rotates. The top of the screw 313 is rotatably connected to the bottom of the pad 312 through a bearing. The screw 313 drives the pad 312 to lift. The adjustment mechanism 3 also includes a torsion block 314, the outer wall of which is fixedly connected to the bottom of the screw 313. Rotating the torsion block 314 can drive the screw 313 to rotate.

[0034] Working principle: The support plate 215 and the abutment head 216 are manually lifted, and the plastic part to be processed can be placed on top of the support base 1. Then, by rotating the abutment handle 213, the abutment handle 213 presses down on the support plate 215 through the connecting plate 214, so that the abutment head 216 abuts against the plastic part. When the abutment handle 213 moves, it drives the rotating rod 212 to rotate, thereby driving the helical gear fixedly connected to the outer wall of the rotating rod 212. Helical gear 217 rotates, which in turn drives helical gear 218, which is meshed with the outer wall of helical gear 217, to rotate. This, in turn, drives rotating rod 219, which is fixedly connected to the inner wall of helical gear 218, to rotate. This causes spur gear 220, which is fixedly connected to the outer wall of rotating rod 219, to rotate. Gear plate 221, which is meshed with the outer wall of spur gear 220, rotates. Gear plate 221 then drives moving block 222 and clamping plate 223 to move. Clamping plate 223 can clamp and support the side wall of the plastic part.

[0035] When it is necessary to support the L-shaped plastic part, by rotating the second torsion block 314, the second torsion block 314 drives the second screw 313 to rotate and descend. The second screw 313 drives the pad 312 to descend through the bearing, so that the lifting groove 311 can be exposed. The depth of the lifting groove 311 can be adjusted according to the shape of the L-shaped plastic part in order to accommodate the L-shaped plastic part.

[0036] The rotating torsion block 226 causes the screw 224 to rotate, which in turn moves the threaded hole block 225 connected to the outer wall of the screw 224. This causes the threaded hole block 225 to move the clamping plate 223, thereby allowing the position of the clamping plate 223 to be adjusted according to the length of the plastic part, so as to stably clamp plastic parts of different lengths.

[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.
