Technical Field
The utility model belongs to the machining technology, and particularly relates to a special-shaped workpiece tool clamp.
Background
The special-shaped part meets specific functions, and is widely applied to various industries such as machinery, metallurgy, electric appliances, agricultural machinery, military industry and the like. For a special-shaped part, no clamp is provided, the special-shaped part cannot be machined, whether the product quality is qualified or not is determined to a great extent by the design of the clamp, the product quality is stable, and the machining efficiency is high or low.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is as follows: the utility model provides a special-shaped part tool clamp capable of machining four surfaces, aiming at solving the problem that a special-shaped part is difficult to machine, and the special-shaped part tool clamp can reliably position and machine 8 parts simultaneously, is simple in clamping, efficient and practical, and greatly improves machining efficiency.
The technical scheme of the utility model is as follows:
a special-shaped piece tool clamp comprises a supporting seat, a fastening screw, a pressing block, a limiting pin and a positioning shaft; the lower part of the supporting seat is in a bar shape, the upper part of the supporting seat is a cuboid, and 1 side surface of the cuboid is provided with a threaded hole, a limiting pin and a positioning shaft; the plane positions of the limiting pin and the positioning shaft are matched with the shape of the special-shaped piece, the special-shaped piece is positioned, and the fastening screw penetrates through the pressing block and then is in threaded connection with the threaded hole, so that the special-shaped piece is fixed on the supporting seat; the number of the limiting pins is 2, and three-point positioning is realized through the positioning shaft.
2 positioning shafts and 4 limit pins are arranged on one side face of the cuboid at the upper part of the supporting seat.
And a zero hole is formed in the top of the cuboid at the upper part of the supporting seat.
Four sides of the cuboid at the upper part of the supporting seat can be simultaneously provided with a positioning shaft and a limiting pin.
The flatness of the side face of the cuboid on the upper portion of the supporting seat is not larger than 0.005 mm.
The bottom surface of the bar at the lower part of the supporting seat is vertical to the side surface of the cuboid.
The utility model has the beneficial effects that:
the utility model adopts an over-constrained clamping mode, stably and reliably positions the special-shaped piece, improves the clamping accuracy and stability of the clamp, solves the problem that the special-shaped piece is difficult to clamp and position, realizes one-time clamping and processing of a plurality of parts, greatly reduces the processing preparation time, improves the processing efficiency, simultaneously reduces the influence of human factors, ensures the consistency of products and has greater practical application value. The utility model provides a tool example and a design idea for efficient machining, and the tool example and the design idea have higher universality and popularization value in the machining of similar products and other occasions.

Detailed Description
The utility model is described in further detail below with reference to the figures and the specific examples.
A special-shaped piece tool clamp comprises a supporting seat 1, a fastening screw 2, a pressing block 3, a limiting pin 4, a special-shaped piece 5 and a positioning shaft 6; the lower part of the supporting seat 1 is in a bar shape, the upper part of the supporting seat is a cuboid, and threaded holes 7, limiting pins 4 and positioning shafts 6 are arranged on 1 side surface of the cuboid; the plane positions of the limiting pin 4 and the positioning shaft 6 are matched with the shape of the special-shaped piece, the special-shaped piece is positioned, the fastening screw 2 penetrates through the pressing block 3 and then is in threaded connection with the threaded hole 7, and the special-shaped piece is fixed on the supporting seat 1; the number of the limiting pins 4 is 2, and three-point positioning is realized through the positioning shaft 6.
Set up 2 location axles and 4 spacer pins on 1 upper portion cuboid side of supporting seat, can realize processing two dysmorphism pieces simultaneously.
A zero hole 8 is formed in the top of the cuboid at the upper portion of the supporting seat 1, and the zero hole 8 is used for determining the coordinate relation between the clamp and a machine tool.
Four sides of the cuboid on the upper part of the supporting seat 1 can be simultaneously provided with a positioning shaft 6 and a limiting pin 4, so that a plurality of groups of special-shaped parts can be simultaneously processed.
The flatness of the side face of the cuboid on the upper portion of the supporting seat 1 is not larger than 0.005mm and is used for correcting the clamp.
The bottom surface of the bar at the lower part of the supporting seat 1 is vertical to the side surface of the cuboid.
