Technical Field

[0001] This utility model relates to the field of air conditioner quick connector processing technology, specifically a clamping device for processing automotive air conditioner quick connectors. Background Technology

[0002] Automotive air conditioning quick-connect fittings are connectors used for quick connection and disconnection of automotive air conditioning systems. They are widely used in various aspects of automotive air conditioning systems, including air conditioning compressor connectors, pipe connection connectors, and pipe repair connectors. Compared with traditional threaded connections, quick-connect fittings make connection and disconnection more convenient, saving a lot of installation and maintenance time.

[0003] The processing of automotive air conditioning quick connectors requires multiple clamping operations. Manually transferring the workpiece leads to repeated positioning errors, reduces coaxiality accuracy, and results in low manual clamping efficiency (increasing single-piece processing time by more than 30%), significantly increasing costs during mass production.

[0004] Therefore, it is necessary to design a clamping device for processing automotive air conditioning quick-connect connectors to improve the processing efficiency and quality. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a clamping device for processing automotive air conditioning quick-connect connectors, thereby solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a clamping device for processing automotive air conditioning quick connectors, including a base, an installation groove on the base, a rotatable first mounting seat on one side of the installation groove, and a docking assembly on the other side of the installation groove. A first groove is provided on the upper side of the first mounting seat, and at least three clamping blocks that move radially around the center of the first groove are provided in the first groove. The docking assembly includes a slide that can slide along the length of the installation groove, and a rotatable second mounting seat is provided on the slide. A second groove is provided on the second mounting seat, and at least three clamping blocks that move radially around the center of the second groove are provided in the second groove.

[0007] The present invention further describes that a first rotating shaft is integrally fixedly connected to the side of the first mounting base away from the center of the mounting groove. The first rotating shaft is rotatably connected to the inner wall of the mounting groove. A second hydraulic telescopic cylinder is provided on the lower side of the first mounting base. The fixed end of the second hydraulic telescopic cylinder is hinged to the bottom of the mounting groove, and the output end of the second hydraulic telescopic cylinder is hinged to the lower end of the side of the first mounting base away from the first rotating shaft.

[0008] The present invention further describes that the slide has a second groove, and the second mounting seat is integrally fixedly connected to the side away from the first mounting seat with a second rotating shaft. The second rotating shaft is rotatably connected to the inner wall of the second groove. A hydraulic telescopic cylinder five is provided on the lower side of the second mounting seat. The fixed end of the hydraulic telescopic cylinder five is hinged to the bottom of the groove, and the output end of the hydraulic telescopic cylinder five is hinged to the lower end of the side of the second mounting seat away from the second rotating shaft.

[0009] The present invention further explains that at least three hydraulic telescopic cylinders are provided in the first groove. The fixed ends of the hydraulic telescopic cylinders are all embedded in the inner wall of the first groove and are fixedly connected to the inner wall of the first groove. Each clamping block is fixedly connected to the output end of one hydraulic telescopic cylinder.

[0010] The present invention further explains that at least three hydraulic telescopic cylinders are provided in the second groove. The fixed ends of the hydraulic telescopic cylinders are all embedded in the inner wall of the second groove and are fixedly connected to the inner wall of the second groove. Each clamping block is fixedly connected to the output end of one hydraulic telescopic cylinder.

[0011] The present invention further explains that the inner walls on both sides of the mounting groove are provided with a fan-shaped groove one corresponding to the first mounting seat. When the first mounting seat is in a horizontal state, the two sides of its top surface abut against the upper groove wall of the fan-shaped groove one.

[0012] The present invention further explains that the inner walls on both sides of the second groove are provided with a fan-shaped groove, and when the second mounting seat is in a horizontal state, the two sides of its upper end face abut against the upper groove wall of the fan-shaped groove.

[0013] This utility model further illustrates that the inner walls of both sides of the mounting groove along the width direction are provided with grooves corresponding to the slide blocks. The slide blocks are disposed in the grooves. Several sliders are fixedly connected to the outer walls of both sides of the slide blocks along the width direction.

The fixed end of the hydraulic telescopic cylinder is fixedly connected to the inner wall of the groove, and the output end of the hydraulic telescopic cylinder is fixedly connected to the slide block.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model realizes the automatic transfer of workpiece from the first process to the second process through the coordinated rotation and sliding docking of the first mounting base and the second mounting base, eliminating the precision loss caused by manual intervention.

[0015] The entire process is automated by using a hydraulic system to drive rotation (hydraulic telescopic cylinder 2 / 5), sliding (hydraulic telescopic cylinder 3), and clamping (hydraulic telescopic cylinder 1 / 4), reducing the processing time per piece and improving production efficiency.

[0016] By using the limiting design of sector-shaped groove one and sector-shaped groove two, the top surface abuts against the upper wall of the groove when the mounting base is in a horizontal state, which enhances the rigidity and anti-cutting vibration effect during processing and improves the processing quality.

[0023] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-4 The present invention provides a technical solution: a clamping device for processing automotive air conditioning quick connectors, including a base 1, the base 1 being mounted on a processing machine tool, the base 1 having an installation groove 2, and a rotatable first mounting seat 3 being provided on one side of the installation groove 2 along its length direction.

[0025] The first mounting base 3 is a rectangular block. The first rotating shaft 4 is integrally fixedly connected to the side of the first mounting base 3 away from the center of the mounting groove 2. The first rotating shaft 4 is rotatably connected to the inner wall of the mounting groove 2.

[0026] The first mounting base 3 has a first groove 5 on its upper side. The first groove 5 is a cylindrical groove. Three hydraulic telescopic cylinders 6 are installed in the first groove 5. The three hydraulic telescopic cylinders 6 are evenly distributed in a circle with the center of the first groove 5 as the center.

[0027] The fixed ends of the three hydraulic telescopic cylinders 6 are all embedded in the inner wall of the first groove 5 and are fixedly connected to the inner wall of the first groove 5. The output ends of the three hydraulic telescopic cylinders 6 are all fixedly connected to clamping blocks 7. Clamping blocks 7 are used to clamp and fix the blank of the air conditioner quick plug. Specifically, the blank of the quick plug is a cylinder.

[0028] The length of the first mounting base 3 along the axis of the first rotating shaft 4 is greater than the width of the mounting groove 2, so that the inner walls on both sides of the mounting groove 2 are provided with fan-shaped grooves 8 corresponding to the first mounting base 3. When the first mounting base 3 is rotated to a horizontal state, the two sides of its top surface abut against the upper groove wall of the fan-shaped groove 8, thereby limiting the first mounting base 3.

[0029] Two hydraulic telescopic cylinders 9 are provided on the lower side of the first mounting base 3. The two hydraulic telescopic cylinders 9 are respectively located on both sides of the mounting groove 2 along the width direction. The fixed end of the hydraulic telescopic cylinder 9 is hinged to the bottom of the mounting groove 2, and the output end of the hydraulic telescopic cylinder 9 is hinged to the lower end of the first mounting base 3 away from the first rotating shaft 4. In this way, the rotation of the first mounting base 3 is controlled by the hydraulic telescopic cylinders 9.

[0030] A docking component 10 is provided on the side of the mounting groove 2 away from the first mounting base 3. The docking component 10 includes a slide block 11 that can slide along the length of the mounting groove 2.

[0031] The width of the slide 11 is greater than the width of the mounting groove 2. Therefore, the inner walls of the mounting groove 2 along the width direction are provided with grooves 12 corresponding to the slide 11. The grooves 12 are connected to the mounting groove 2. The slide 11 is set in the grooves 12. The outer walls of the slide 11 along the width direction are in contact with the inner walls of the grooves 12.

[0032] Specifically, several sliders 13 are fixedly connected to the outer walls of both sides of the slide block 11 along the width direction. The sliders 13 are arranged linearly and evenly along the height direction of the slide block 11. The cross-sectional shape of the sliders 13 is dovetail-shaped. The inner wall of the groove 12 is provided with a groove 14 corresponding to the sliders 13. The sliders 13 and the grooves 14 cooperate to make the slide block 11 slide in the groove 12.

[0033] Four hydraulic telescopic cylinders 15 are provided on the side of the slide block 11 away from the first mounting seat 3. The four hydraulic telescopic cylinders 15 are located at the four corners of the slide block 11. The fixed end of the hydraulic telescopic cylinder 15 is fixedly connected to the inner wall of the groove 12, and the output end of the hydraulic telescopic cylinder 15 is fixedly connected to the slide block 11. Thus, the movement of the slide block 11 is controlled by the hydraulic telescopic cylinders 15.

[0034] The slide 11 has a second groove 16, and a rotatable second mounting seat 17 is provided in the second groove 16. The second mounting seat 17 is a rectangular block. A second rotating shaft 18 is integrally fixedly connected to the side of the second mounting seat 17 away from the first mounting seat 3. The second rotating shaft 18 is rotatably connected to the inner wall of the second groove 16.

[0035] The second mounting base 17 has a second groove 19, which is a cylindrical groove. Three hydraulic telescopic cylinders 20 are installed in the second groove 19. The three hydraulic telescopic cylinders 20 are evenly distributed in a circle with the center of the second groove 19 as the center.

[0036] The fixed ends of the three hydraulic telescopic cylinders 20 are all embedded in the inner wall of the second groove 19 and are fixedly connected to the inner wall of the second groove 19. The output ends of the three hydraulic telescopic cylinders 20 are all fixedly connected to clamping blocks 21. Clamping blocks 21 are used to clamp and fix one end of the quick connector blank after it has been processed on the first mounting seat 3.

[0037] The length of the second mounting base 17 along the axis of the second rotating shaft 18 is greater than the groove width of the second groove 16, so that the inner walls of both sides of the second groove 16 are provided with fan-shaped grooves 22 corresponding to the second mounting base 17. When the second mounting base 17 is rotated to a horizontal state, the two sides of its upper end face abut against the groove wall of the fan-shaped groove 22, thereby limiting the second mounting base 17.

[0038] Two hydraulic telescopic cylinders 23 are provided on the lower side of the second mounting base 17. The two hydraulic telescopic cylinders 23 are respectively located on both sides of the groove 16 along the width direction. The fixed end of the hydraulic telescopic cylinder 23 is hinged to the bottom of the groove 16, and the output end of the hydraulic telescopic cylinder 23 is hinged to the lower end of the second mounting base 17 away from the second rotating shaft 18. In this way, the rotation of the second mounting base 17 is controlled by the hydraulic telescopic cylinders 23.

[0039] In this embodiment, the cylindrical blank to be processed into an air conditioner quick connector is first placed in the first groove 5 of the first mounting base 3. Then, the output end of the hydraulic telescopic cylinder 6 is extended to clamp the blank with the clamping block 7. Since the blank is cylindrical, the central axis of the blank coincides with the central axis of the first groove 5, thereby achieving the centering effect.

[0040] The upper part of the blank is processed by the cutting tool on the machining tool to form the upper part structure of the air conditioner quick plug. Its outer surface is still a cylindrical structure so that the clamping block 21 on the second mounting base 17 can be clamped and fixed later.

[0041] After machining is completed on the first mounting base 3, the machine tool controls the tool to move and reset, and then controls the output end of the hydraulic telescopic cylinder 9 to retract, so that the first mounting base 3 rotates to a vertical state.

[0042] At the same time, the second mounting base 17 is also rotated to a vertical position under the action of the hydraulic telescopic cylinder 23. Then, the slide 11 is controlled to slide towards the side closer to the first mounting base 3 by the hydraulic telescopic cylinder 3 15.

[0043] Ultimately, the side of the blank on the first mounting base 3 that is furthest from the first mounting base 3 comes into direct contact with the bottom of the second groove 19 on the second mounting base 17.

[0044] Subsequently, the output end of the hydraulic telescopic cylinder 20 is extended, so that the clamping block 21 clamps and fixes the blank. Since the outer surface of the part of the blank after processing on the first mounting seat 3 is cylindrical, the central axis of the blank coincides with the central axis of the second groove 19.

[0045] After clamping block 21 clamps and fixes the blank, the output end of hydraulic telescopic cylinder 6 is retracted, and clamping block 7 stops clamping the blank.

[0046] Subsequently, the output end of the hydraulic telescopic cylinder 15 is retracted, and after the slide 11 moves and resets, the output end of the hydraulic telescopic cylinder 23 is extended again, and the second mounting base 17 is rotated to a horizontal state, with both sides of its upper end face abutting against the upper groove wall of the fan-shaped groove 22.

[0047] The cutting tool on the machining tool is controlled again to process the unprocessed part of the blank on the second mounting base 17. After processing, it can become the finished product of the air conditioner quick connector, thus achieving efficient processing of the air conditioner quick connector.
