Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tooling fixture technology, specifically a quick-release positioning device for tooling fixtures. Background Technology
[0002] Tooling fixtures are devices used to fix workpieces during the manufacturing process, which helps to maintain the workpiece's positioning and prevents displacement during processing, thus ensuring workpiece machining accuracy and efficiency. However, some machining steps require machining multiple surfaces of the workpiece, which necessitates using tooling fixtures to position the workpiece at different angles. However, each time the workpiece needs to be repositioned and clamped, it must be removed, the angle adjusted, and then clamped and positioned again. This is not only cumbersome, but repeated disassembly and reassembly can also easily cause workpiece positioning deviation, thereby affecting subsequent machining accuracy. Therefore, this application proposes a quick-release positioning device for tooling fixtures. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides the following technical solution: A quick-release positioning device for tooling fixtures, comprising a base plate, with two symmetrical clamping assemblies fixedly installed on the top of the base plate. Each clamping assembly includes a support plate, a fixing part, a rotating rod, a pressing rod, and a pressing plate. The support plate is vertically installed on the top of the base plate, and an opening is provided on the top side of the support plate. The fixing part is shaped like a round rod, with one end of the fixing part fixedly inserted into the opening on the support plate. A through hole is provided at one end of the fixing part, through which the rotating rod is rotatably inserted. A groove is provided at one end of the rotating rod, and the pressing rod is movably inserted into the groove at one end of the rotating rod. A round hole is provided on the side of the pressing plate, and the round hole on the side of the pressing plate is movably sleeved on the rotating rod.

Three second hydraulic rods are evenly and fixedly installed at the end of the fixed part away from the extrusion plate. The telescopic ends of the three second hydraulic rods all pass through the fixed part and are fixedly connected to the side of the extrusion plate.
[0005] Preferably, a rubber layer is provided on the side of the extrusion rod away from the first hydraulic rod and on the side of the extrusion plate away from the second hydraulic rod.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] Depend on Figure 1-4The present invention includes a base plate 1, on the top of which two symmetrical clamping assemblies are fixedly installed. Each clamping assembly includes a support plate 2, a fixing part 3, a rotating rod 4, a pressing rod 6, and a pressing plate 8. The support plate 2 is vertically installed on the top of the base plate 1, and an opening is provided on the top side of the support plate 2. The fixing part 3 is shaped like a round rod, and one end of the fixing part 3 is fixedly inserted into the opening on the support plate 2. A through hole is provided at one end of the fixing part 3, and the rotating rod 4 is rotatably inserted into the through hole. A rod groove 5 is provided at one end of the rotating rod 4, and the pressing rod 6 is movably inserted into the through hole. In the groove 5 at one end of the rotating rod 4, a round hole 9 is provided on the side of the extrusion plate 8. The round hole 9 on the side of the extrusion plate 8 is movably sleeved on the rotating rod 4. By controlling the two first hydraulic rods 7, the two extrusion rods 6 first clamp and position the workpiece. Then, the motor 12 can drive the rotating rod 4 to rotate. The rotation of the rotating rod 4 can change the angle of the clamped workpiece. After the angle of the workpiece is adjusted, the second hydraulic rod 10 is controlled to push the extrusion plate 8 to clamp and fix the position of the workpiece. In this way, the angle adjustment of the workpiece to be processed can be completed quickly without the need for multiple disassembly and assembly of the workpiece.
[0019] like Figure 2 and Figure 3 As shown, a first hydraulic rod 7 is fixedly installed at the end of the rotating rod 4 away from the rod groove 5. The telescopic end of the first hydraulic rod 7 extends into the rod groove 5 and is fixedly connected to the end of the extrusion rod 6 located in the rod groove 5. Three second hydraulic rods 10 are evenly and fixedly installed at the end of the fixing part 3 away from the extrusion plate 8. The telescopic ends of the three second hydraulic rods 10 all pass through the fixing part 3 and are fixedly connected to the side of the extrusion plate 8. The telescopic end of the first hydraulic rod 7 can push the extrusion rod 6 to move its position in the rod groove 5 at one end of the rotating rod 4. By bringing the two extrusion rods 6 closer to each other, the workpiece to be processed can be initially clamped. The telescopic end of the second hydraulic rod 10 can push the extrusion plate 8 to move along the direction of the rotating rod 4. By bringing the two extrusion plates 8 closer to each other, the workpiece with the adjusted angle can be further fixed and clamped.
[0020] like Figure 2 and Figure 3 As shown, the side of the extrusion rod 6 away from the first hydraulic rod 7 and the side of the extrusion plate 8 away from the second hydraulic rod 10 are both provided with rubber layers. Through the rubber layers on the sides of the extrusion rod 6 and the extrusion plate 8, the friction between the extrusion rod 6, the extrusion plate 8 and the workpiece can be increased, thereby increasing the stability of the workpiece clamping and providing a certain degree of protection for the clamped workpiece.
[0021] like Figure 1 As shown, a motor 12 is fixedly installed on the left end of the top of the base plate 1. A transmission assembly 13 is provided between the output end of the motor 12 and the rotating rod 4 in the clamping assembly on the left. The operation of the motor 12 can provide power for the rotation of the rotating rod 4.
[0022] like Figure 1 As shown, the transmission assembly 13 includes two sprockets and a chain. The two sprockets are respectively fixedly installed on the output end of the motor 12 and the outer wall of the left end of the rotating rod 4. The chain drive is sleeved between the two sprockets. The transmission assembly 13 can transmit the power generated by the motor 12 when it is running to the rotating rod 4, so that the rotating rod 4 can rotate between the fixed parts 3. Under the mutual squeezing action of the squeezing rods 6 at one end of the two rotating rods 4, the workpiece clamped between the two squeezing rods 6 can be driven to rotate at an angle.
[0023] like Figure 4 As shown, annular grooves are provided at both ends of the inner wall of the through hole on the fixing part 3. A bearing 11 is fixedly installed in each annular groove. The inner ring walls of the two bearings 11 are fixedly sleeved on the outer wall of the corresponding rotating rod 4. The bearings 11 can fix the position of the rotating rod 4 in the through hole in the fixing part 3, so that the rotating rod 4 can rotate stably in the through hole in the fixing part 3.
