Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and more specifically, to a fixture for CNC machining of automotive parts. Background Technology
[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for machining or inspection; it is also called a clamp. CNC machining fixtures are often used when machining automotive parts.
[0003] For example, CN216178517U discloses a CNC machining fixture for automotive parts. The key technical points of this fixture are: it includes a base plate one, a base plate two, and a clamping assembly. The base plate two is symmetrically arranged on one side of the base plate one. A connecting hinge is installed at the bottom end of the base plate one where it connects to the base plate two. Two support sleeves are symmetrically arranged on one side of the bottom end of the base plate one, and two support columns are symmetrically arranged on one side of the bottom end of the base plate two. The clamping assembly is installed on the upper ends of both the base plate one and the base plate two. The clamping assembly includes a mounting plate, an electric actuator one installed in the middle of one side wall of the mounting plate, and a clamping rod installed on the electric actuator one. The clamp consists of an inverted L-shaped clamping plate at one end, mounting sleeves on both sides of the upper end of the clamping plate, an electric actuator rod II installed inside the mounting sleeve, a pressure plate at the bottom end of the electric actuator rod II, and an infrared human body sensor installed in the middle of one side wall of the clamping plate. Both the base plate and the base plate II have lifting handles on their side walls, and an operation panel is installed at one corner of the upper end of the base plate. Its design, primarily through the connection of hinges, lifting handles, support sleeves, and support columns, allows for convenient folding of the clamp when not in use, effectively reducing the clamp's volume and space occupation, facilitating its storage and maintenance, and demonstrating good practicality.
[0004] The aforementioned fixture for CNC machining of automotive parts also has certain shortcomings: since the fixture is fixed inside the CNC lathe, if the position of the automotive parts needs to be changed, the repeated disassembly and assembly of the fixture will increase the working time and thus reduce the working efficiency of the device. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fixture for CNC machining of automotive parts to solve the problems existing in the prior art.
[0006] To solve the above technical problems, the present invention provides the following technical solution: a fixture for CNC machining of automotive parts, comprising a fixture body, a rotating component fixedly connected to the lower surface of the fixture body, a stabilizing base fixedly connected to the bottom end of the rotating component, and a moving component fixedly connected to the bottom end of the stabilizing base.
[0007] The clamp body includes a connecting base, a first mounting plate, a first hydraulic telescopic rod, and a clamping plate. Two first mounting plates are fixedly connected to the upper surface of the connecting base symmetrically along the center. Two first hydraulic telescopic rods are detachably installed on the side wall of the first mounting plate symmetrically along the center. A clamping plate is fixedly connected to one end of each first hydraulic telescopic rod.
[0008] The rotating assembly includes a first stabilizing base, a first connecting rod, and a spur gear. A first bearing is embedded in the center of the upper surface of the first stabilizing base. The first connecting rod is fixedly sleeved inside the first bearing. The spur gear is fixedly sleeved on the surface of the first connecting rod. The lower surface of the first stabilizing base is connected to the upper surface of the stabilizing base.
[0009] The first stabilizing base has four grooves arranged in a rectangular array on its upper surface. Limiting rings are bonded to the inside of the grooves. A first stabilizing plate is fixedly connected to one side of the upper surface of the first stabilizing base. A second hydraulic telescopic rod is detachably installed on the top of the side wall of the first stabilizing plate. A spur gear is fixedly connected to one end of the second hydraulic telescopic rod. The side wall of the spur gear meshes with the side wall of the circular gear. The limiting rings are made of rubber.
[0010] The upper surface of the first stabilizing base is secured with a protective shell by a limiting ring, and the lower surface of the protective shell is fixedly connected with four second connecting rods in a rectangular array. The bottom end of the second connecting rods is adapted to the inside of the limiting ring.
[0011] The protective shell has a second bearing embedded in the middle of its upper surface. A third connecting rod is fixedly sleeved inside the second bearing. The top end of the third connecting rod is connected to the center of the lower surface of the connecting base, and the bottom end of the third connecting rod is connected to the top end of the first connecting rod.
[0012] The moving component includes a second stabilizing base and a second stabilizing plate. Four second stabilizing plates are fixedly connected to the upper surface of the second stabilizing base in a rectangular array, and the lower surface of the second stabilizing base is connected to the interior of the lathe.
[0013] The second stabilizing plate has a limit rod fixedly connected to its side wall, and a slider is movably sleeved on the surface of the limit rod. The upper surface of the slider is connected to the lower surface of the stabilizing base.
[0014] A third stabilizing plate is fixedly connected to one side of the upper surface of the second stabilizing base. A third hydraulic telescopic rod is detachably installed at the top of the side wall of the third stabilizing plate. One end of the third hydraulic telescopic rod is connected to the middle of the side wall of the slider.
[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0016] 1. In the above solution, the fixture is equipped with a moving component. When it is necessary to change the position of the automotive parts, the third hydraulic telescopic rod inside the moving component is activated, which pushes the slider that is movably sleeved on the surface of the limiting rod. Since the automotive parts to be processed are connected to the slider through the fixture body, the rotating component and the stabilizing base, the movement of the slider can drive the automotive parts to move until the automotive parts are moved to the required working position. Since the third hydraulic telescopic rod has an automatic extension and retraction function, the position of the automotive parts can be freely adjusted, thereby saving the time required for the work.
[0017] 2. In the above solution, the clamp is equipped with a rotating component. When it is necessary to change the direction of the clamp body, the second hydraulic telescopic rod inside the rotating component is activated, causing it to drive the spur gear to move. Because the side wall of the spur gear meshes with the side wall of the circular gear, and the circular gear is fixedly sleeved on the surface of the first connecting rod, the movement of the spur gear can drive the first connecting rod to rotate. Since the clamp body is connected to the first connecting rod through the second connecting rod, the rotation of the first connecting rod can drive the clamp body to rotate until the clamp body is rotated to the ideal angle, thereby enhancing the practicality of the device.

When it is necessary to change the direction of the clamp body 1, the second hydraulic telescopic rod 26 inside the rotating component 2 is activated, causing it to drive the spur gear 27 to move. Since the side wall of the spur gear 27 meshes with the side wall of the circular gear 23, and the circular gear 23 is fixedly sleeved on the surface of the first connecting rod 22, the movement of the spur gear 27 can drive the first connecting rod 22 to rotate. Since the clamp body 1 is connected to the first connecting rod 22 through the second connecting rod 29, the rotation of the first connecting rod 22 can drive the clamp body 1 to rotate until the clamp body 1 is rotated to the ideal angle, thereby enhancing the practicality of the device.
