Description

Technical Field

[0001] The utility model belongs to the technical field of plastic welding devices, and in particular relates to a plastic welding machine. Background Art

[0002] Plastic welding machine (also known as ultrasonic plastic welding machine) transmits ultrasonic energy to the welding area through the upper welding piece. Since the welding area, i.e. the interface between the two welds, has a large acoustic impedance, local high temperature will be generated. Since the thermal conductivity of plastic is poor, it cannot be dissipated in time and accumulates in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain pressure is applied, they are fused into one.

[0003] Chinese utility model disclosure specification CN210082437U discloses a plastic welding machine, including a support plate, a support frame, a control box and a welding plate. The left side of the support frame is fixedly connected to a limiting cylinder, and both sides of the top of the welding plate are slidably connected with movable rods to support the welding parts through the welding table.

[0004] However, when welding different welding parts, the welding table cannot be suitable for all welding parts, so molds suitable for different welding parts are required to carry them. When replacing and disassembling the mold, the above-mentioned device is fixed with bolts. During the disassembly and assembly process, it is necessary to remove and install bolts at multiple diagonal positions. It cannot be disassembled and assembled quickly and is relatively troublesome, which reduces work efficiency. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 5 A plastic welding machine comprises a welding machine body 1, a clamp body 2, and a base 3, wherein the clamp body 2 is detachably mounted on the base 3 and is used to clamp and release two plastic components to be welded;

[0026] In a further embodiment, an adjusting block 201 is rotatably mounted on the clamp body 2 via an adjusting shaft 202, and a clamping plate 203 is fixedly mounted on one end of the adjusting block 201 away from the adjusting shaft 202. It should be noted that a groove 204 is provided in the clamp body 2, and the length of the clamping plate 203 is less than or equal to the length of the groove 204. The clamping plate 203 rotates with the adjusting block 201 and has at least two states, wherein the two states are a locked state and a released state.

[0027] In a further embodiment, an upper positioning plate 304 and a lower positioning plate are provided at the position of the base 3 corresponding to the card plate 203, and the upper positioning plate 304 and the lower positioning plate are fixedly mounted on the positioning sleeve 302, and the positioning sleeve 302 is rotatably mounted on the positioning shaft in the positioning seat 303, and the positioning shaft is fixedly mounted on the positioning seat 303, and the positioning seat 303 is fixedly mounted on the base 3, and a positioning rod 306 is inserted in the positioning shaft, and the positioning rod 306 is slidably connected to the slide groove in the positioning shaft, and a spring is installed on the inner wall of the slide groove, and a crescent plate 305 is fixedly installed on the positioning sleeve 302. The distances between the various parts of the crescent plate 305 and the center point are different, so the crescent plate 305 will squeeze the positioning rod 306 during the rotation process, and the positioning rod 306 will squeeze the spring inward, and the spring accumulates elastic potential energy, and when it rotates to the crescent plate 305 When the upper positioning groove is reached, the positioning rod 306 will be inserted into the positioning groove, and a positioning groove is provided in the crescent plate 305, and the positioning groove cooperates with the positioning rod 306. In the locked state, the lower end surface of the adjustment block 201 is pressed on the upper side of the clamp body 2, and the upper positioning plate 304 is located on the upper side of the card plate 203; at this time, the upper positioning plate 304 on the positioning sleeve 302 is locked, and the position of the card plate 203 pressed by it is locked. Since the upper positioning plate 304 is located on the upper side of the card plate 203, the clamp body 2 cannot move up and down at this time. At the same time, the clamp body 2 is plugged into the card groove 301 in the base 3. The clamp body 2 cannot move forward and backward or left and right under the restriction of the card groove 301, and the position between it and the base 3 is locked in the locked state. In the released state, the clamp body 2 can be inserted into the base 3 or pulled out from the base 3 by plugging and unplugging;

[0028] Specifically, after the positioning rod 306 is inserted into the positioning groove, the entire positioning sleeve 302 will be stuck by the positioning rod 306, and the positioning sleeve 302 cannot continue to rotate. The clamping plate 203 is inserted between the upper positioning plate 304 and the lower positioning plate, and its position is fixed;

[0029] In a further embodiment, in order to enhance the fixing effect on the fixture body 2, a first bevel gear 307 is fixedly installed on the positioning sleeve 302, and the first bevel gear 307 is connected to the second bevel gear 308 through tooth meshing transmission. The second bevel gear 308 is rotatably installed on the connecting seat, and the connecting seat is fixedly installed on the base 3. The second bevel gear 308 is fixedly connected to the upper pressure plate 309, and the clamping plate 203 is in a locked state. The lower end surface of the upper pressure plate 309 is pressed on the upper side of the fixture body 2.

[0030] Working principle:

[0031] The steps for installing the fixture body 2 on the base 3 are as follows:

[0032] First, insert the fixture body 2 into the slot 301 in the base 3;

[0033] Second, the adjusting block 201 on the fixture body 2 is rotated. During the rotation process, the clamping plate 203 connected to the adjusting block 201 is inserted between the upper positioning plate 304 and the lower positioning plate in the positioning sleeve 302. The adjusting block 201 continues to rotate, and the positioning rod 306 is aligned with the positioning groove in the crescent plate 305. The positioning rod 306 is inserted therein, and the position of the positioning sleeve 302 is fixed;

[0034] Third, during the rotation of the positioning sleeve 302, the upper pressing plate 309 is driven to rotate to the upper side of the fixture body 2 through the first bevel gear 307 and the second bevel gear 308, thereby completing the fixation between the fixture body 2 and the base 3;

[0035] When removing the fixture body 2 from the base 3, the steps are as follows:

[0036] Pull the positioning rod 306, rotate the positioning sleeve 302, pull the clamping plate 203 out from between the upper positioning plate 304 and the lower positioning plate, and pull the clamp body 2 upward to complete the disassembly work.
