Description

Technical Field

[0001] This utility model relates to an automatic flipping clamping device, belonging to the field of automatic flipping fixture technology. Background Technology

[0002] The automotive air conditioning system is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to the optimal state, providing a comfortable riding environment for passengers, reducing travel fatigue, and creating good working conditions for the driver. The mode panel structure of the automotive air conditioning assembly is an important component of air conditioning regulation. However, the shape of the air conditioning mode panel used in different car models often varies. In order to reduce friction between parts and extend the service life during the assembly process, grease needs to be applied to specific positions on both sides or one side of the mode panel before assembling the sliding rod or ball joint. Some models only require grease application to one side. Since the styles of mode panels vary greatly, it is essential to design a suitable automatic flipping and clamping device. Utility Model Content

[0003] This invention addresses the shortcomings of the prior art by providing an automatic flipping clamping device.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] An automatic flipping clamping device includes a flipping cylinder and a connected clamping cylinder. The clamping cylinder is provided with a first positioning fixture or a second positioning fixture that can be detachably connected below it, and detachably connected grippers on both sides of the output end. Both the second positioning fixture and the first positioning fixture include a fixing part and a positioning part. The positioning part of the first positioning fixture includes a groove, and a support part is provided in the groove. An annular channel is provided between the support part and the inner sidewall of the groove.

[0006] Furthermore, the support portion is C-shaped.

[0007] Furthermore, the grooves are all hollow except for the support portion and the annular channel.

Detailed Implementation

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] like Figures 1-6 As shown, an automatic flipping clamping device includes a flipping cylinder 4 and a connected clamping cylinder 3. A first positioning fixture 5 or a second positioning fixture 6 that can be detachably connected is provided below the clamping cylinder 3, and jaws 2 that can be detachably connected are provided on both sides of the output end. Both the second positioning fixture 6 and the first positioning fixture 5 include a fixing part and a positioning part. The positioning part of the first positioning fixture 5 includes a groove 51, and a support part 52 is provided in the groove 51. An annular channel 54 is provided between the support part 52 and the inner sidewall of the groove 51.

[0025] The support portion 52 is C-shaped.

[0026] Except for the support portion 52 and the annular channel 54, the groove 51 is hollow.

[0027] The positioning part of the second positioning fixture 6 is provided with an arc-shaped limit 61.

[0028] The second positioning fixture 6 has a positioning hole 62 at the center of its positioning part.

[0029] The range of motion angle of the gripper 2 is 75° to 145°.

[0030] The gripper 2 has a symmetrical arc shape.

[0031] The first positioning fixture 5 or the second positioning fixture 6 is provided with a fixing hole 7 for connecting to the clamping cylinder 3.

[0032] A connecting plate 41 is provided between the clamping cylinder 3 and the tilting cylinder 4.

[0033] The rotation angle of the tilting cylinder 4 is 360°.

[0034] In use, first connect the left side of the flipping cylinder 4 to two of the connecting holes on the connecting plate 41. The other side of the connecting plate 41 is connected to the right side of the first positioning fixture 5 or the second positioning fixture 6 through other connecting holes. The fixing part of the first positioning fixture 5 or the second positioning fixture 6 is connected and fixed to the lower end of the clamping cylinder 3 above through the fixing hole 7. The two sides of the output end of the clamping cylinder 3 are detachably connected to the gripper 2. The first positioning fixture 5 or the second positioning fixture 6 is integrally formed.

[0035] During operation, when the workpiece is a pattern plate A 53, the pattern plate A 53 is placed in the positioning groove 51 of the first positioning fixture 5 (the groove 51 serves as an overall limit). After the support part 52 supports the pattern plate A 53, the clamping cylinder 3 drives the gripper 2 to clamp the outside of the track groove of the pattern plate A 53. Then, the grease injection device injects grease into the front of the pattern plate A 53. After the front is completed, the flipping cylinder 4 drives the pattern plate A 53 to flip and inject grease into the back. The clamping of the gripper 2 prevents the pattern plate A 53 from shaking during the grease injection process, so that the movable rod ball head can be installed later to make it move back and forth in the track groove of the pattern plate.

[0036] When the workpiece is pattern plate B 63, pattern plate B 63 is placed on the positioning part of the second positioning fixture 6. The lower end of pattern plate B 63 protrudes into the positioning hole 62. After the arc-shaped limiter 61 limits the outer side of pattern plate B 63, the clamping cylinder 3 drives the gripper 2 to clamp the outer side of pattern plate B 63. Then, the grease injection device injects grease into the front of pattern plate A 53. The clamping of the gripper 2 prevents the pattern plate B 63 from shaking during the grease injection process, so that the movable rod ball head can be installed later to make it move back and forth in the track groove of the pattern plate.

[0037] The automatic flipping clamping device can be adapted to either the first positioning fixture 5 or the second positioning fixture 6 to achieve rapid double-sided flipping grease injection or single-sided grease injection during the model plate assembly process. This results in high work efficiency, convenient replacement, reduced assembly costs, time savings, and good performance. The detachable design of the first positioning fixture 5 or the second positioning fixture 6 expands the device's compatibility with different types of model plates, and allows for direct replacement and updates based on the model plate's style, increasing the overall adaptability of the device, reducing production costs, and facilitating replacement. The clamping claw 2 clamps the model plate after it is positioned, preventing it from shaking during grease injection and allowing it to rotate to adapt to the grease injection requirements of different vehicle models. The groove 51 and support 52 on the first positioning fixture 5 cooperate with the outermost track groove on the bottom of the model plate A 53 that requires grease injection, displaying the entire groove and enabling more efficient positioning during grease injection, thereby improving grease injection efficiency.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
