Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a multi-station clamp for rapid clamping. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process of the process can be called a fixture. A fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), a dividing device (to enable the workpiece to complete the processing of several stations in one installation, and there are two types of rotary dividing devices and linear moving dividing devices), connecting elements, and a clamp body (fixture base).

[0003] Although the existing multi-station clamps can clamp multiple parts for processing in one processing, they use manual tightening and loosening clamps such as flat-nose pliers, so it takes a lot of time to adjust the tightness of each part each time the parts are installed or removed. In addition, under long-term operation, it is easy to cause the parts to be loosened during the processing, causing damage to the clamps, tools, etc. Therefore, the utility model proposes a multi-station clamp for fast clamping. Summary of the invention

[0004] The utility model provides a multi-station clamp for fast clamping to solve the problems mentioned in the above background technology.

[0005] The purpose of the utility model is achieved by the following methods:

[0006] A multi-station clamp for quick clamping, comprising a base, a fixed block and a plurality of receiving grooves are provided at the upper end of the base, the base is provided with a first through hole and a second through hole connected to the receiving groove, the receiving groove is provided with a clamping assembly that cooperates with the fixed block, the clamping assembly comprises an end cover installed at one end of the receiving groove, a piston that can slide up and down in the receiving groove, an axis installed on the piston, a pressure block fixed on the axis, and a sliding block that slides with the pressure block.

[0007] Furthermore, the pressing block and the sliding block are respectively provided with a limiting block and a limiting groove for cooperating with each other, and a limiting spring is provided between the limiting block and the limiting groove.

[0008] Furthermore, the accommodating grooves are symmetrically disposed on both sides of the fixing block.

[0009] Furthermore, the base is provided with a fixing groove.

[0010] Furthermore, the fixed block and the sliding block are respectively installed with a first jaw plate and a second jaw plate that cooperate with each other.

[0011] Furthermore, mounting plates extending outward are provided on both sides of the base, and waist-shaped holes are provided on the mounting plates.

[0012] Furthermore, handles are installed on both sides of the base.

[0013] The beneficial effects of the utility model are as follows: the first through hole and the second through hole connected to the receiving groove are connected to an external liquid or gas source, so that the piston in the receiving groove can slide up and down, thereby driving the pressure block on the axis to cooperate with the sliding block, so that the sliding block translates and cooperates with the fixed block to achieve the effect of clamping or disassembly. Therefore, by controlling the piston to slide up and down, fast clamping or disassembly can be achieved, reducing the time required for clamping or disassembly and improving work efficiency.

[0023] Furthermore, the fixing block 2 is installed on the upper end of the base 1 by screws, the end cover 6 is sealed with the receiving groove 3 by threads, sealing rings are provided at the connection between the piston 7 and the receiving groove 3 and the axis 8, and the pressure block 9 is fixed to the stepped shaft of the axis 8 by a nut.

[0024] Furthermore, the first through hole 4 and the second through hole 5 are both provided with joints connected to an external liquid or gas source, and the joints of the first through hole 4 and the second through hole 5 are connected in series through connecting pipes, so as to achieve the effect of multi-station synchronous clamping by controlling one switch.

[0025] Furthermore, placement grooves for placing connecting pipes are provided on both sides of the base 1 to prevent the connecting pipes from affecting the installation and removal of the clamp.

[0026] Furthermore, the pressing block 9 and the sliding block 10 are respectively provided with a limit block 11 and a limit groove 12 for cooperating with each other, and a limit spring 13 is provided between the limit block 11 and the limit groove 12. The limit block 11 cooperates with the limit groove 12 so that the sliding block 10 can only move in a specific direction under the push of the pressing block 9, and the limit spring 13 ensures that the sliding block 10 can return to the initial position after the pressure disappears, and limits the upward movement of the sliding block 10 to prevent it from accidentally falling off, thereby increasing the flexibility and service life of the clamp.

[0027] Furthermore, the receiving grooves 3 are symmetrically arranged on both sides of the fixing block 2, so that both sides of the fixing block 2 are fully utilized for clamping and the force is more balanced, thereby improving the stability and service life of the fixing block 2.

[0028] Furthermore, the base 1 is provided with a fixing groove 14. The shape of the fixing groove 14 matches the outer shape of the pressing block 9 and the sliding block 10 to ensure that the pressing block 9 and the sliding block 10 can stably slide along the path of the fixing groove 14 during the movement, improve the parallelism with the fixing block 2, and further enhance the stability and accuracy of the clamp.

[0030] Furthermore, mounting plates 17 extending outward are provided on both sides of the base 1 , and waist-shaped holes 18 are provided on the mounting plates 17 .

[0031] The mounting plates 17 extending outward from both sides of the base 1 facilitate the user to install the fixture on the machine tool. The waist-shaped hole 18 is designed so that the position of the fixture can be adjusted within a small range during installation to meet the needs of different machine tools or working environments. This design not only improves the applicability of the fixture, but also reduces the difficulty of installation and improves work efficiency.

[0032] Furthermore, handles 19 are installed on both sides of the base 1 by screws. When installing or removing the fixture, the handles 19 can be used to easily carry and position it, which reduces the difficulty of operation and improves work efficiency. The design of the handles 19 also takes ergonomics into consideration, making it more comfortable to hold and reducing fatigue caused by long-term operation. And the handles 19 can be removed after installation to reduce space occupation.

[0033] The beneficial effects of the utility model are as follows: the first through hole 4 and the second through hole 5 connected to the receiving groove 3 are connected to an external liquid or gas source, so that the piston 7 in the receiving groove 3 can slide up and down, thereby driving the pressing block 9 on the axis 8 to cooperate with the sliding block 10, so that the sliding block 10 translates and cooperates with the fixed block 2 to achieve the effect of clamping or disassembly. Therefore, by controlling the piston 7 to slide up and down, fast clamping or disassembly can be achieved, reducing the time required for clamping or disassembly and improving work efficiency. This improves the practicality and convenience of the clamp.
