Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a machining fixture for metal parts. Background Technology

[0002] In the field of metal parts machining, fixtures are the core devices for workpiece positioning, clamping and transmission of machining loads. Their performance directly affects machining accuracy, production efficiency and manufacturing cost. With the rapid development of the manufacturing industry, traditional fixtures can no longer meet the needs of modern machining. Therefore, it is particularly important to develop a machining fixture for metal parts.

[0003] A four-axis machining fixture for metal parts, as described in CN220050902U, includes a fixed circular plate, a connecting plate, a limiting frame, a push plate, a first fixed clamp, a second fixed clamp, and an arc-shaped fixed clamp. The bottom ends of the fixed circular plates are fixedly connected to each other. The top ends of the connecting plates are symmetrically fixedly mounted with the limiting frames centered on their center lines. A support frame is fixedly connected to the middle of the limiting frames. A slide rod is fixedly connected to the middle of the support frame and the limiting frames. A push plate is slidably connected to the outer wall of the slide rod. The top ends of the push plate are fixedly connected to the first and second fixed clamps. An arc-shaped fixed clamp is provided on one side of the second fixed clamp. When clamping and fixing the part to be processed, the arc-shaped fixed clamp slides along a third slide rail to adjust its position, facilitating the clamping of smooth-surfaced raw materials. As can be seen from the above, although this machining fixture can be used effectively, it is generally not convenient for clamping and fixing metal parts from all four sides, making it difficult to achieve the expected fixing effect on metal parts, and further improvement is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a machining fixture for metal parts, so as to solve the problem mentioned in the background art that although the machining fixture can be used well, it is usually not convenient to clamp and fix the metal parts from all sides, so that the fixing effect of the machining fixture on the metal parts is still difficult to achieve the expected result.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machining fixture for metal parts, comprising a base, with side supports fixedly installed on both sides of the bottom end of the base, two first support seats on one side of the top end of the base, and two second support seats on the other side of the top end of the base, a second limiting seat fixedly installed on the top end of one of the first support seats, and a first telescopic cylinder mounted on the top end of the other of the first support seats via a bracket, with two first limiting seats fixedly installed on the top end of the base on the side of the first telescopic cylinder, and two strip seats fixedly installed at the bottom end of the base between the side supports, with a first electric push rod rotatably installed on the inner wall of each strip seat, a first drive frame installed at one end of the first electric push rod, a linkage arm rotatably installed on the inner wall of the first drive frame, the top end of the linkage arm penetrating the base and having a chuck installed thereon, and a positioning seat rotatably installed on the outer wall of the linkage arm, the bottom end of the positioning seat being fixedly connected to the top end of the base.

[0006] Preferably, a second abutment seat is fixedly installed on the top of the base on one side of the second support seat, and a third telescopic cylinder is installed on the top of the base on the other side of the second support seat via a bracket. The third telescopic cylinder is used to abut and limit the metal fittings at the top of the second support seat.

[0007] Preferably, a first abutment seat is fixedly installed on the top of the base on one side of the third telescopic cylinder, and a second telescopic cylinder is installed on the top of the base on the other side of the third telescopic cylinder via a bracket. The second telescopic cylinder is provided to abut and limit the metal fittings at the top of the second support seat.

[0008] Preferably, a second electric push rod is installed at the bottom end of the base at the second support position. The top end of the second electric push rod passes through the base and is equipped with a second drive frame. A pressure head is rotatably installed on the top of the second drive frame. The pressure head is used to press down and fix the metal fittings at the top of the second support.

[0009] Preferably, a limiting arm is rotatably installed on the inner wall of the lower end of the pressure head, and a placement frame is rotatably installed at the end of the limiting arm away from the pressure head. The bottom end of the placement frame is fixedly connected to the top end of the base. The limiting arm is used to limit the movement range of the pressure head.

[0010] Preferably, a lifting cylinder is installed on the outer wall of the base between the first limiting seats via a bracket, and a pressure plate is installed at the top of the lifting cylinder. The lifting cylinder is configured to drive the pressure plate to perform lifting and lowering operations.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the machining fixture for metal parts can not only clamp and fix the metal parts from all sides, but also easily press down and fix the metal parts to ensure the fixing effect of the machining fixture on the metal parts when it is used, and achieve the purpose of easily clamping and fixing the metal parts in two ways.

[0012] (1) By placing the metal parts vertically on the top of the two first support seats, the outer walls of the two sides of the metal parts are respectively attached to the inner walls of the second limit seat and the first limit seat. Then, the first telescopic cylinder is activated to extend and retract, so as to abut the outer wall of the metal parts. Then, the first electric push rod is activated to extend and retract slightly, so as to drive the linkage arm to rotate on the inner wall of the positioning seat, so that the linkage arm drives the chuck to rotate and attach to the outer wall of the metal parts. The metal parts can be clamped and fixed from all sides, thus ensuring the fixing effect of the machining fixture on the metal parts when it is used.

[0013] (2) By placing the metal parts flat on the top of the two second support seats, the outer walls of the two sides of the metal parts are respectively attached to the inner walls of the first abutment seat and the second abutment seat. Then, the third telescopic cylinder and the second telescopic cylinder are activated to extend and retract, so that they abut against the other two outer walls of the metal parts respectively. The metal parts can be clamped and fixed from all sides, thus achieving the purpose of easily clamping and fixing the metal parts in two ways.

[0014] (3) By starting the lifting cylinder, the pressure plate is driven to move downward, so that the pressure plate moves down and fits against the top of the metal part, thus pressing down and fixing the metal part placed at the top of the first support seat. Then, the two ends of the limiting arm are rotatably connected to the placement frame and the limiting arm respectively. When the second electric push rod is started to extend and retract, the pressure head is driven to rotate downward through the second drive frame, so that the pressure head presses down and fixes the metal part at the top of the second support seat, thereby further improving the fixing effect of the machining fixture on the metal part.
