Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a multi-station clamp for a machining center. Background Art

[0002] The machining center fixture is a tool used to clamp the workpiece for processing on the machining center. It can ensure that the workpiece maintains a stable position and posture during the machining process, thereby ensuring the machining accuracy and quality. The machining center fixture is usually composed of a fixture bed, a fixture clamping device, a fixture positioning device, and a fixture adjustment device.

[0003] For example, a clamp for a machining center disclosed in publication number CN219426192U has the following beneficial effects: by rotating the bidirectional threaded screw to adjust the distance between the two drive components, the length of the shaft parts to be processed is adapted, and then the trapezoidal block is driven to slide up and down by sliding the electric telescopic rod up and down, further driving the trapezoidal block to contact the two pulleys, changing the distance between the upper ends of the two arc-shaped clamping rods, thereby adapting to the diameter of the shaft parts to be processed, and thus better adapting to different types of shaft parts. It has a wider range of applications and higher efficiency, and effectively reduces the frequency of fixture replacement. However, the clamp has only one station, which means that only one workpiece can be clamped for processing at a time, and multiple workpieces cannot be processed at the same time, resulting in low production efficiency. Due to low production efficiency and limited production capacity, it may also lead to increased production costs, thereby affecting the competitiveness of the enterprise. Therefore, there are certain limitations and it cannot meet the user's usage needs. A multi-station clamp for a machining center needs to be developed urgently. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-station clamp for a machining center, which has the advantage of having an extra station and being able to clamp two workpieces at the same time, thereby solving the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-station fixture for a machining center, comprising a base, one side of the top of the base is fixedly connected with a telescopic oil cylinder 1 and a telescopic oil cylinder 2 respectively, the top of the base is fixedly connected with a symmetrically distributed slide rail 1 and a symmetrically distributed slide rail 2, the surface of the slide rail 1 is slidably connected with a symmetrically distributed slide seat 1 and a symmetrically distributed slide seat 2, the surface of the slide rail 2 is slidably connected with a symmetrically distributed slide seat 3 and a symmetrically distributed slide seat 4, a fixed column is fixedly connected at the center of the top of the base, a transmission gear 1 is sleeved on the top of the surface of the fixed column, and a long rack 1 is fixedly connected to one side of the slide seat 4. The output end of the telescopic cylinder one is fixedly connected to a long rack one, and a short rack one is fixedly connected to one side of the slide one, and the long rack one and the short rack one are both meshed with a transmission gear one, and one side of the slide one and the slide three are both fixedly connected to a clamping seat one, and one side of the slide two and the slide four are both fixedly connected to a clamping seat two, and one side of the slide two is fixedly connected to a long rack two, the output end of the telescopic cylinder two is fixedly connected to a long rack two, and one side of the slide three is fixedly connected to a short rack two, and a transmission gear two is sleeved on the bottom of the surface of the fixed column, and the long rack two and the short rack two are both meshed with a transmission gear two.

[0006] Furthermore, as a preferred embodiment of the present invention, a rubber anti-skid pad is fixedly connected to one side of the clamping seat 1 and the other side of the clamping seat 2, and a surface of the rubber anti-skid pad is provided with anti-skid patterns.

[0007] Furthermore, as a preferred embodiment of the utility model, the bottoms of the clamping seat one and the clamping seat two are fixedly connected with two symmetrically distributed supporting slide rails, and the two sides of the top of the base are fixedly connected with two symmetrically distributed supporting slide seats, and the supporting slide rails are slidably connected to the surfaces of the supporting slide seats.

[0008] Furthermore, as a preferred embodiment of the present invention, the inner walls of the transmission gear 1 and the transmission gear 2 are fixedly connected with bearings, and the inner walls of the bearings are fixedly connected to the surface of the fixing column.

[0009] Furthermore, as a preferred embodiment of the present invention, the top of the base is provided with four symmetrically distributed positioning holes, and the positioning holes are located at the four corners of the top of the base.

[0010] Beneficial effects. The technical solution of the present application has the following technical effects: the utility model has the advantage of having an extra workstation, which can clamp two workpieces at the same time. In actual use, through the coordinated use of telescopic cylinder 1 and telescopic cylinder 2, the two clamping seats 1 and 2 can be driven to move relative to each other at the same time, thereby completing the clamping operation of the two workpieces. An extra workstation means that one more workpiece can be clamped and processed at the same time, thereby improving production efficiency and shortening production cycle. An extra workstation also increases production capacity, which can meet the needs of mass production, and effectively solves the problem that the above-mentioned fixture has only one workstation, which will lead to low production efficiency and increased production costs.
