Description

Technical Field

[0001] This utility model relates to the field of plastic welding fixtures, and in particular to a plastic welding fixture with a matching floating clamping device. Background Technology

[0002] Hot melt welding is a commonly used welding process in the welding of plastic products. It involves heating the contact surfaces of two products to be welded until they melt, and then applying relative pressure to the two products to join the molten parts together. This allows for the rapid and secure welding of plastic parts.

[0003] When applying pressure to two products to be welded, the two products need to be clamped by a jig to ensure that the welding surfaces of the two products can be accurately and stably aligned until the molten welding is completed. Therefore, the clamping jig is an indispensable tool to ensure welding quality.

[0004] Existing welding clamping fixtures typically clamp plastic products by pushing two clamping plates or blocks closer together with a screw until the product to be welded is clamped and fixed. However, when clamping by pushing the clamping plates or blocks with a screw, it is often difficult to accurately control the force. If the force is too small, the product to be welded may wobble or move slightly during the clamping process, which will affect the welding quality. If the force is too large, the product to be welded may be damaged by strong compression, which will also reduce the quality of the welding process.

[0005] To solve the above problems, there is an urgent need for a plastic welding fixture with a matching floating clamping device. Utility Model Content

[0006] The purpose of this utility model is to provide a plastic welding fixture with a matching floating clamping device, so as to solve the problem mentioned in the background art that the existing plastic welding clamping fixtures are difficult to accurately control the clamping force when clamping the products to be welded, resulting in a reduction in welding quality.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a plastic welding fixture with a matching floating clamping device, comprising a base plate and a welding component, wherein a contoured cavity is provided at the top center of the base plate, the welding component is adapted to the contoured cavity and is inserted into the contoured cavity, two floating clamping assemblies are connected to the top of the base plate, and a limiting assembly is also connected to the top of the base plate;

[0008] The two floating clamping assemblies can clamp the welded parts in the X-axis and Y-axis directions respectively by elastic force in conjunction with the contoured cavities;

[0009] The limiting component is used to limit one of the floating clamping components so that the floating clamping component remains in the state of releasing the weldment.

[0010] Preferably, the floating clamping assembly includes a first limiting groove and a second limiting groove formed on the top of the base plate. One side of the second limiting groove is connected to the inner wall of the first limiting groove, and the side of the second limiting groove away from the first limiting groove is connected to the inner wall of the contoured cavity. An elastic clamping mechanism is connected in the first limiting groove. A first limiting block is slidably connected in the first limiting groove and is connected to the elastic clamping mechanism. A clamping plate is slidably connected in the second limiting groove. One side of the clamping plate is fixedly connected to the side of the first limiting block. The elastic clamping mechanism presses tightly against the side of the weldment under the elastic force and clamps the weldment. The advantage of this design is that the elastic clamping mechanism pushes the clamping plates to press tightly against the side of the weldment. In this way, the two clamping plates can cooperate with the conformal cavity to clamp and fix the weldment. Furthermore, the elastic clamping mechanism provides clamping force through the elastic element, which can ensure the accuracy and stability of the clamping force. Thus, while ensuring reliable clamping of the weldment, it avoids the weldment from shaking or displacement during welding or being excessively squeezed and deformed, thereby ensuring the quality and effect of the welding process.

[0011] Preferably, the elastic clamping mechanism includes two first circular holes symmetrically formed on the side of the first limiting block away from the contour cavity. Two second circular holes are symmetrically formed on the inner walls of the two first circular holes. The ends of the two second circular holes away from the first circular holes penetrate the side wall of the first limiting block near the contour cavity. Two circular plates are symmetrically and movably inserted into the two first circular holes. Two circular rods are symmetrically and fixedly connected to the sides of the two circular plates near the contour cavity. The two circular rods are symmetrically and movably inserted into the two second circular holes. The two circular rods respectively penetrate the two second circular holes and are fixedly inserted into the inner wall of the first limiting groove. Two first elastic elements are symmetrically and fixedly connected between the two circular plates and the inner walls of the two first circular holes. The advantage of this arrangement is that, under the limiting action of the first limiting groove, the second circular holes, and the circular rods, the clamping plate can move stably along the length direction of the first limiting groove. This ensures that the clamping force applied by the clamping plate to the weldment remains stable in position and direction, improving the clamping firmness and reliability of the weldment, thereby improving the quality and effect of the welding process.

[0012] Preferably, the floating clamping assembly further includes a first pull plate and a second pull plate fixedly connected to the top of the first limiting block. A rectangular groove with a spacing of not less than three centimeters is left between the adjacent sides of the first pull plate and the second pull plate. The advantage of this setting is that the operator can choose to pull the first pull plate or the second pull plate according to the needs and operating habits, which makes it easier for the operator to pull the clamping plate away from the welding part and improves the ease of operation of the tool.

[0013] Preferably, the limiting component includes a third limiting groove formed on the base plate, the third limiting groove being perpendicular to and communicating with one of the first limiting grooves. A second limiting block is slidably connected to the first limiting groove. A second elastic element is fixedly connected to the side of the third limiting block away from the contoured cavity. A fixing post is fixedly connected to the side of the second elastic element away from the second limiting block. The other end of the fixing post is fixedly inserted into the inner wall of the third limiting groove. A retaining plate is fixedly connected to the side of the second limiting block near the contoured cavity. The retaining plate can be inserted into a rectangular... Inside the groove, a third pull plate is fixedly connected to the top of the second limiting block. The advantage of this arrangement is that by moving the first limiting block away from the contour cavity until the clamping plate is inserted into the rectangular groove under the elastic force of the second elastic element, the clamping plate can be limited to move away from the weldment. Thus, the operator only needs to pull the other clamping plate away from the contour cavity, which frees up the operator's other hand to remove the weldment or insert the weldment into the contour cavity. This makes it easier for the operator to pick up and put down the weldment, further improving the convenience of the fixture.

[0014] Preferably, the top of the third limiting groove is fixedly connected to a limiting plate by a screw, and the bottom of the limiting plate is in contact with the top of the clamping plate. The advantage of this arrangement is that the limiting plate, together with the third limiting groove, can better limit the clamping plate and ensure the stability of the clamping plate's movement trajectory. This allows the clamping plate to be smoothly inserted into the rectangular groove, thereby ensuring that the limiting operation of the clamping plate can be successfully completed, and improving the reliability and practicality of the fixture.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, the conformal cavity can accurately position the weldment, and the two floating clamping components clamp the weldment in the X-axis and Y-axis directions respectively with elastic force. This ensures that the floating clamping components can provide a more stable and accurate clamping force to the weldment, thereby ensuring reliable clamping of the weldment and preventing the weldment from shaking or being deformed by excessive compression during welding, thus ensuring the quality and effect of the welding process.

[0017] 2. In this utility model, by setting a limiting component, the first limiting block is moved away from the molded cavity until the clamping plate is inserted into the rectangular groove under the elastic force of the second elastic element. This limits the clamping plate so that it is away from the welding part. Thus, the worker only needs to pull the other clamping plate away from the molded cavity, which frees up the worker's other hand to take out the welding part or insert the welding part into the molded cavity. This makes it easier for the worker to pick up and put down the welding part, and further improves the convenience of the tool. Attached Figure Description

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

[0027] Please refer to Figures 1-6The plastic welding fixture shown includes a base plate 1 and a welding component 2. A contoured cavity 3 is provided at the top center of the base plate 1. The welding component 2 is adapted to the contoured cavity 3 and is inserted into the contoured cavity 3. Two floating clamping assemblies 4 are connected to the top of the base plate 1. A limiting assembly 5 is also connected to the top of the base plate 1.

[0028] The two floating clamping components 4 can clamp the welded part 2 in the X-axis and Y-axis directions respectively with the conformal cavity 3 through elastic force;

[0029] The limiting component 5 is used to limit one of the floating clamping components 4 so that the floating clamping component 4 is kept in the state of releasing the welded part 2.

[0030] refer to Figures 1-4 The floating clamping assembly 4 includes a first limiting groove 41 and a second limiting groove 42 formed on the top of the base plate 1. One side of the second limiting groove 42 is connected to the inner wall of the first limiting groove 41, and the side of the second limiting groove 42 away from the first limiting groove 41 is connected to the inner wall of the contour cavity 3. An elastic clamping mechanism 43 is connected in the first limiting groove 41. A first limiting block 44 is slidably connected in the first limiting groove 41 and is connected to the elastic clamping mechanism 43. A clamping plate 45 is slidably connected in the second limiting groove 42. One side of the clamping plate 45 is fixedly connected to the side of the first limiting block 44. Under the elastic force of the elastic clamping mechanism 43, the clamping plate 45 presses tightly against the side of the welded part 2 and clamps the welded part 2.

[0031] Specifically, the elastic clamping mechanism 43 pushes the clamping plate 45 tightly against the side of the weldment 2 through the elastic force of the clamping mechanism 43. In this way, the two clamping plates 45 can cooperate with the contour cavity 3 to clamp and fix the weldment 2. The elastic clamping mechanism 43 provides clamping force through the elastic element, which can ensure the accuracy and stability of the clamping force. Thus, while ensuring reliable clamping of the weldment 2, it avoids the weldment 2 from shaking or displacement during welding or being excessively squeezed and deformed, thus ensuring the quality and effect of welding processing.

[0032] refer to Figures 1-4The elastic clamping mechanism 43 includes two first circular holes 431 symmetrically opened on the side of the first limiting block 44 away from the contour cavity 3. Two second circular holes are symmetrically opened on the inner sidewalls of the two first circular holes 431. One end of the two second circular holes away from the first circular holes 431 passes through the sidewall of the first limiting block 44 near the contour cavity 3. Two circular plates 432 are symmetrically and movably inserted into the two first circular holes 431. Two circular rods 433 are symmetrically and fixedly connected on the sidewalls of the two circular plates 432 near the contour cavity 3. The two circular rods 433 are symmetrically and movably inserted into the two second circular holes. The two circular rods 433 pass through the two second circular holes and are fixedly inserted into the inner sidewall of the first limiting groove 41. Two first elastic elements 434 are symmetrically and fixedly connected between the two circular plates 432 and the inner sidewalls of the two first circular holes 431.

[0033] Specifically, under the limiting action of the first limiting groove 41, the second circular hole and the circular rod 433, the clamping plate 45 can move stably along the length direction of the first limiting groove 41. This ensures that the clamping force of the clamping plate 45 on the welded part 2 remains stable in position and direction, improves the clamping firmness and reliability of the welded part 2, and thus improves the quality and effect of welding processing.

[0034] refer to Figure 1 and Figure 4 The floating clamping assembly 4 also includes a first pull plate 46 and a second pull plate 47 fixedly connected to the top of the first limiting block 44, and a rectangular groove 48 with a spacing of not less than three centimeters is left between the adjacent sides of the first pull plate 46 and the second pull plate 47.

[0035] Specifically, this allows workers to choose to pull the first pull plate 46 or the second pull plate 47 according to their needs and operating habits, making it easier for workers to pull the clamping plate 45 away from the welded part 2, thus improving the ease of operation of the fixture.

[0036] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The limiting component 5 includes a third limiting groove 51 formed on the base plate 1. The third limiting groove 51 is perpendicular to and connected to one of the first limiting grooves 41. A second limiting block 52 is slidably connected to the first limiting groove 41. A second elastic member 54 is fixedly connected to the side of the second limiting block 52 away from the contoured cavity 3. A fixing post 53 is fixedly connected to the side of the second elastic member 54 away from the second limiting block 52. The other end of the fixing post 53 is fixedly inserted into the inner wall of the third limiting groove 51. A clamping plate 55 is fixedly connected to the side of the second limiting block 52 near the contoured cavity 3. The clamping plate 55 can be inserted into the rectangular groove 48. A third pull plate 56 is fixedly connected to the top of the second limiting block 52.

[0037] Specifically, by moving the first limiting block 44 away from the contour cavity 3 until the clamping plate 55 is inserted into the rectangular groove 48 under the elastic force of the second elastic member 54, the clamping plate 45 can be limited so that it is away from the weldment 2. Thus, the operator only needs to pull the other clamping plate 45 away from the contour cavity 3, which frees up the operator's other hand to take out the weldment 2 or insert the weldment 2 into the contour cavity 3. This makes it easier for the operator to pick up and put down the weldment 2, further improving the convenience of the tool.

[0038] refer to Figure 1 , Figure 2 and Figure 5 The top of the third limiting groove 51 is fixedly connected to the limiting plate 57 by a screw, and the bottom of the limiting plate 57 is in contact with the top of the card plate 55.

[0039] Specifically, the limiting plate 57, in conjunction with the third limiting groove 51, can better limit the clamping plate 55, ensuring the stability of the movement trajectory of the clamping plate 55. This allows the clamping plate 55 to be smoothly inserted into the rectangular groove 48, thereby ensuring that the limiting operation of the clamping plate 45 can be successfully completed, improving the reliability and practicality of the fixture.

[0040] Working principle: Pulling the first pull plate 46 or the second pull plate 47 pulls the clamping plate 45 away from the welding part 2. At this time, the first limiting block 44 moves away from the contour cavity 3 until the clamping plate 55 is inserted into the rectangular groove 48 under the elastic force of the second elastic element 54. In this way, the clamping plate 45 can be limited so that the clamping plate 45 is away from the welding part 2. Thus, the operator only needs to pull the other clamping plate 45 away from the contour cavity 3, so that the operator's other hand can be freed to insert the welding part 2 into the contour cavity 3.

[0041] Then release the first pull plate 46 or the second pull plate 47, so that the clamping plate 45 is reset and clamps the welded part 2 under the elastic force of the first elastic member 434.

[0042] Then, pull the third pull plate 56 and drive the clamping plate 55 to be pulled out from the rectangular groove 48. At this time, the first limiting block 44 where the rectangular groove 48 is located will drive the clamping plate 45 to move towards the weldment 2 until it is pressed against the side of the weldment 2. In this way, the two clamping plates 45, together with the inner wall of the contour cavity 3, can conveniently and reliably clamp the weldment 2, ensuring that the subsequent welding process can be carried out smoothly.

[0043] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
