Description

Technical Field

[0001] The utility model relates to the technical field of synchronous clamps, in particular to a hydraulic transmission structure of a synchronous clamp. Background Art

[0002] At present, the types of fixtures mainly include general fixtures, special fixtures and combination fixtures. Their common feature is that during the clamping process, the grippers of the fixture cannot be guaranteed to be synchronized, and the accuracy is not high. However, in some occasions, it must be ensured that the clamped object must remain in its original position throughout the entire clamping process, so the grippers of the fixture are required to be synchronized. For example, when the robot on the low-pressure casting machine takes the part from the upper mold, the grippers of the manipulator are required to be synchronized. Otherwise, if one of the grippers of the manipulator touches the casting first, the casting may lose balance and fall. At this time, the grippers of the manipulator must touch the casting at the same time. Fixtures are an important link that directly restricts the quality of products and the length of production cycles.

[0003] The guide column four-axis structure of the synchronous clamp in the prior art is a one-to-two structure, and only one external oil cylinder can be installed to clamp one workpiece, which has low working efficiency. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a synchronous clamp hydraulic transmission structure capable of clamping multiple workpieces.

[0005] The utility model is realized by the following method: a synchronous clamp hydraulic transmission structure, comprising a support base, a four-axis seat is arranged at the left end of the upper surface of the support base, a tail seat is arranged at the right end of the upper surface of the support base, end plates are arranged on the inner side surfaces of the four-axis seat and the tail seat, guide columns are arranged on the front and rear sides of the lower ends between the left and right end plates, a plurality of clamping members are arranged at equal distances on the guide columns, and a rotating oil supply member for supplying oil to the clamping members is arranged in the end plates.

[0006] Furthermore, the rotating oil supply part includes a rotary oil circuit block, which is fixedly installed on the outer side of the four-axis seat via a fixed plate, and the rotary oil circuit block is provided with an oil inlet pipe and an oil return pipe. The clamping part is provided with a built-in oil cylinder, and the built-in oil cylinder is connected to the oil inlet pipe and the oil return pipe.

[0007] Furthermore, the clamping member includes a fixed clamp seat and a movable clamp seat, both of which are sleeved on the guide column, and the built-in oil cylinder is arranged in the fixed clamp seat.

[0008] The beneficial effects of the present invention are as follows: the present invention adds multiple clamping parts, rotating oil supply parts and guide pillars in the device, which can realize the clamping and loosening actions of multiple groups of clamping parts and realize the clamping effect of multiple workpieces at the same time; the present invention has a simple structure and is easy to operate, which can effectively save manpower and material resources and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is further described below in conjunction with the accompanying drawings.

[0011] See also Figure 1 As shown, the utility model provides an embodiment: a synchronous clamp hydraulic transmission structure, including a support base 1, a four-axis seat 2 is arranged at the left end of the upper surface of the support base 1, a tailstock 3 is arranged at the right end of the upper surface of the support base 1, and end plates 4 are arranged on the inner side of the four-axis seat 2 and the inner side of the tailstock 3, and guide columns 5 are arranged on both the front and rear sides of the lower ends between the left and right end plates 4, and multiple clamping members 6 are arranged at equal distances on the guide columns 5, and a rotating oil supply member 7 for supplying oil to the clamping members 6 is arranged in the end plate 4. Through the action of the rotating oil supply member 7, the multiple clamping members 6 can be supplied with oil, and then the clamping members 6 clamp or release multiple workpieces on the guide columns 5.

[0012] Please continue reading Figure 1 As shown, in one embodiment of the utility model, the rotating oil supply member 7 includes a rotary oil circuit block 71, the rotary oil circuit block 71 is fixedly mounted on the outer side of the four-axis seat 2 via a fixed plate, the rotary oil circuit block 71 is provided with an oil inlet pipe 72 and an oil return pipe 73, and the clamping member 6 is provided with a built-in oil cylinder (not shown), and the built-in oil cylinder is connected to the oil inlet pipe 72 and the oil return pipe 73. Oil is supplied through the rotary oil circuit block 71, and oil is supplied to the built-in oil cylinder through the oil inlet pipe 72, so that the clamping member 6 can be clamped, and the clamping member 6 can be loosened through the action of the oil return pipe 73.

[0013] Please continue reading Figure 1 As shown, in one embodiment of the utility model, the clamping member 6 includes a fixed clamp seat 61 and a movable clamp seat 62, both of which are sleeved on the guide column 5, and the fixed clamp seat 61 is provided with the built-in oil cylinder, so that the movable clamp seat 62 can slide on the guide column 5 to achieve the clamping and release of the workpiece.
