Description

Technical Field

[0001] This utility model relates to the field of welding station technology, specifically a positioning welding station for polymer diffusion welding equipment. Background Technology

[0002] Polymer diffusion welding equipment melts and penetrates polymer materials into the workpiece surface through heating and pressurization, achieving efficient welding. Its features include: short welding time and high efficiency; simple post-weld processing; applicability to various metals and complex structural parts; environmental protection and good economic benefits. It is widely used in the manufacturing of high value-added products such as automobiles and aerospace. In the welding process, a positioning welding table is usually used to assist in positioning the workpiece to be welded.

[0003] Positioning welding stations can assist in positioning during the welding process and improve welding accuracy, but they still have certain problems: 1) After welding, the welding station is at a high temperature, and it needs to be allowed to cool down slightly before the workpiece can be fixed again, which poses certain safety hazards and is inconvenient for operators; 2) It cannot achieve simultaneous multi-step operation, resulting in low work efficiency; 3) It is not convenient to fine-tune the spacing of the welding seats. Therefore, in view of the above situation, there is an urgent need to develop a positioning welding station for polymer diffusion welding equipment to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a positioning welding station for polymer diffusion welding equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning welding table for a polymer diffusion welding equipment, comprising a welding equipment body and a welding table for fixing the workpiece to be welded, the welding table being fixed on one side of the welding equipment body;

[0006] The welding table includes a support, a rotating track, a motor a, and welding support assemblies. The support is fixed on one side of the main body of the welding equipment. The rotating track is rotatably mounted on the top of the support. The motor a is fixed in the middle of the support and the rotating track is driven by the motor a. Multiple sets of welding support assemblies are equidistantly mounted on the rotating track in a radiating pattern around the rotation axis.

[0007] The welding support assembly includes a slide rail a, an adjustable seat, and a welding positioning seat. The slide rail a is fixed to the top edge of the rotating track. The bottom of the adjustable seat is fixed with a slider a, which is slidably connected to the slide rail a. The top of the adjustable seat is fixed with a slide rail b, and the bottom of the welding positioning seat is fixed with a slider b, which is slidably connected to the slide rail b.

[0008] Preferably, the welding support assembly consists of four sets. Specifically, the four sets of welding support assemblies rotate on the rotating track, sequentially driving the workpiece to be welded into the main body of the welding equipment for welding operations, thus forming four workstations: welding workstation, unloading workstation, cooling workstation, and loading workstation. The coordinated operation of multiple workstations can effectively improve work efficiency.

[0009] Preferably, a motor b is fixed at one end of the slide rail a, and a lead screw is installed at the output end of the motor b. A lead screw nut is fixed at the middle position of the bottom of the adjustable seat, and the lead screw nut is connected to the lead screw drive. Specifically, the motor b, in conjunction with the lead screw and the lead screw nut, can drive the adjustable seat to move horizontally along the slide rail a.

[0010] Preferably, an electric cylinder is fixedly installed on one side of the adjustable seat, and the end of the output shaft of the electric cylinder is fixedly connected to the welding positioning seat. Specifically, the electric cylinder can drive the welding positioning seat to move horizontally along the slide rail b.

[0011] Preferably, the stroke accuracy of the electric cylinder is higher than that of the lead screw. Specifically, due to the difference in accuracy between the two, the lead screw is responsible for long-stroke coarse positioning, while the electric cylinder is responsible for short-stroke precise positioning, ensuring welding positioning accuracy and efficiency.

[0012] Compared with the prior art, this utility model provides a positioning welding table for polymer diffusion welding equipment, which has the following beneficial effects:

[0013] It adopts four sets of welding support components in conjunction with a rotating track to form a cyclical multi-station structure, which can realize the simultaneous operation of multiple processes, effectively improve work efficiency, and provide a certain amount of time for the welding support components after welding to dissipate heat, which facilitates the subsequent assembly of the parts to be welded. The adjustable seat and the welding positioning seat are driven by a lead screw and an electric cylinder respectively, which can realize long-stroke rapid positioning and short-stroke high-precision positioning respectively. The combination of the two effectively ensures positioning accuracy. Attached Figure Description

[0022] Example:

[0023] Please see Figures 1-4 The present invention provides a technical solution: a positioning welding table for a polymer diffusion welding equipment, comprising a welding equipment body 10 and a welding table 20 for fixing the workpiece to be welded, the welding table 20 being fixed on one side of the welding equipment body 10.

[0024] The welding table 20 includes a support 201, a rotating track 202, a motor a203, and welding support assemblies 204. The support 201 is fixed on one side of the main body 10 of the welding equipment. The rotating track 202 is rotatably mounted on the top of the support 201. The motor a203 is fixed in the middle of the support 201 and the rotating track 202 is driven by the motor a203. Multiple sets of welding support assemblies 204 are equidistantly mounted on the rotating track 202 in a radiating pattern around the rotation axis.

[0025] The welding support assembly 204 includes a slide rail a2042, an adjustable seat 2044, and a welding positioning seat 2045. The slide rail a2042 is fixed to the top edge of the rotating track 202. The bottom of the adjustable seat 2044 is fixed with a slider a2047, which is slidably connected to the slide rail a2042. The top of the adjustable seat 2044 is fixed with a slide rail b2049. The bottom of the welding positioning seat 2045 is fixed with a slider b20451, which is slidably connected to the slide rail b2049.

[0026] Preferably, there are four sets of welding support assemblies 204. Specifically, the four sets of welding support assemblies 204 rotate on the rotating track 202, and sequentially drive the workpiece to be welded into the main body 10 of the welding equipment for welding operations. This forms four workstations, namely the welding workstation, the unloading workstation, the cooling workstation, and the loading workstation. The coordinated operation of multiple workstations can effectively improve work efficiency.

[0027] Preferably, a motor b2041 is fixedly mounted at one end of the slide rail a2042, and a lead screw 2043 is installed at the output end of the motor b2041. A lead screw nut 2048 is fixedly mounted at the middle position of the bottom of the adjustable seat 2044. The lead screw nut 2048 is connected to the lead screw 2043 for transmission. Specifically, the motor b2041, in conjunction with the lead screw 2043 and the lead screw nut 2048, can drive the adjustable seat 2044 to move horizontally along the slide rail a2042.

[0028] Preferably, an electric cylinder 2046 is fixedly installed on one side of the adjustable seat 2044. The end of the output shaft of the electric cylinder 2046 is fixedly connected to the welding positioning seat 2045. Specifically, the electric cylinder 2046 can drive the welding positioning seat 2045 to move horizontally along the slide rail b2049.

[0029] Preferably, the stroke accuracy of the electric cylinder 2046 is higher than that of the lead screw 2043. Specifically, due to the difference in accuracy between the two, the lead screw 2043 is responsible for long-stroke coarse positioning, while the electric cylinder 2046 is responsible for short-stroke precise positioning, ensuring welding positioning accuracy and efficiency.

[0030] Working principle: The four sets of welding support assemblies 204 on the welding table 20 correspond to four workstations, respectively responsible for feeding, welding, heat dissipation, and unloading. The operator uses a special fixture to fix the workpiece to be welded on the welding positioning seat 2045. Then, the motor a203 drives the rotating track 202 and the welding support assembly 204 to rotate 90 degrees. Immediately afterwards, the motor b2041 drives the lead screw 2043 in conjunction with the lead screw nut 2048 to drive the adjusting seat 2044 to move along the slide rail a2042 through the slider a2047, so that the adjusting seat 2044... 044 moves a certain distance toward the main body 10 of the welding equipment. Then, the electric cylinder 2046 starts the welding positioning seat 2045 and the workpiece to be welded on it to move along the slide rail b2049 via the slider b20451. This causes the welding positioning seat 2045 to move the workpiece to be welded to the designated position of the main body 10 of the welding equipment, and the workpiece to be welded is welded. After the welding is completed, it is reset and continues to be rotated 90 degrees by the motor a203 in conjunction with the rotating track 202 to the next station to cooperate with the external equipment for heat dissipation. Then, the unloading and loading are carried out.
