Abstract
The utility model discloses a processing tool for a connecting rod bush on a screw pump. The processing tool is used for clamping the connecting rod bush when the inner conical surface of the connecting rod bush is processed. The processing tool comprises a tool base and a rectangular workpiece clamp block, wherein the rectangular workpiece clamp block is arranged on the tool base; a hole for allowing the connecting rod bush to be vertically arranged is formed on the workpiece clamp block; a vertical part is arranged on the tool base; two adjacent surfaces of the workpiece clamp block are respectively jointed with the top surface of the tool base and the side surface of the vertical part; the workpiece clamp block is placed obliquely; and an included angle with the degree as the same as the conical degree of the inner conical surface of the connecting rod bush is formed between the plane in the length direction of the workpiece clamp block and the horizontal direction. After the adoption of the scheme, the processing tool is used for clamping the connecting rod bush; and when the inner conical surface of the connecting rod bush is processed, the connecting rod bush is inclined and processed by a milling cutter directly, the operation is simple, and the processing precision of the connecting rod bush is high.
Description
Technical field
The utility model relates to the production equipment of screw pump and parts thereof, and specifically, the utility model relates to a kind of processing tool that is used for the connecting rob bushing on the screw pump.
Background technology
At present; The endoporus that is used for the connecting rob bushing on the screw pump is provided with inner conical surface, and this inner conical surface is adding man-hour through milling cutter processing; Because neither one auxiliary equipment preferably comes the clamping connecting rob bushing; It is cumbersome to cause processing to be got up, and the connecting rob bushing inner conical surface machining accuracy after the processing is relatively poor, does not meet the product quality requirement.
The utility model content
The utility model technical problem to be solved provides a kind of processing tool that is used for the connecting rob bushing on the screw pump, to reach the processing of being convenient to connecting rob bushing and the purpose that improves the inner conical surface machining accuracy of connecting rob bushing.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of processing tool that is used for the connecting rob bushing on the screw pump; Be used for connecting rob bushing and carrying out the clamping that inner conical surface adds man-hour; Said processing tool comprises frock base and the workpiece clamp that is located at the rectangle on this frock base; On said workpiece clamp, be provided with the hole of the said connecting rob bushing of vertical placement, on said frock base, be provided with a vertical portion, said workpiece clamp two adjacent surfaces is fitted with the end face of said frock base and the side of said vertical portion respectively; And be skewed placement, between the plane of its length direction and the horizontal direction with an angle with the identical angle of tapering of the inner conical surface of said connecting rob bushing.
Junction in said frock base and said vertical portion is provided with slot to make way.
Hole on the said workpiece clamp is located at the centre position that workpiece clamps the block length direction.
Said workpiece clamp tilts towards the direction of said slot to make way.
Be provided with on the said frock base with said workpiece clamp on the hole that is connected, hole.
The utility model adopts technique scheme, through this device connecting rob bushing is carried out clamping, when processing connecting rob bushing inner conical surface; It is skewed that connecting rob bushing promptly is, and can directly process connecting rob bushing with milling cutter, simple to operate; Working (machining) efficiency is high, and the connecting rob bushing machining accuracy is high.
Description of drawings
Fig. 1 is the utility model structural representation;
Mark among the above-mentioned figure is: 1, frock base; 2, workpiece clamp; 3, connecting rob bushing; 4, vertical portion; 5, milling cutter.
The specific embodiment
As shown in Figure 1, a kind of processing tool that is used for the connecting rob bushing on the screw pump of the utility model is used for connecting rob bushing 3 and is carrying out the clamping that inner conical surface adds man-hour; Said processing tool comprises frock base 1 and the workpiece clamp 2 that is located at the rectangle on this frock base 1; On said workpiece clamp 2, be provided with the hole of the said connecting rob bushing 3 of vertical placement, on said frock base 1, be provided with a vertical portion 4, said workpiece clamp 2 two adjacent surfaces are fitted with the end face of said frock base 1 and the side of said vertical portion 4 respectively; And be skewed placement; Between the plane of its length direction and the horizontal direction with an angle with the identical angle of tapering of the inner conical surface of said connecting rob bushing 3, the connecting rob bushing 3 that is placed on the workpiece clamp 2 also is skewed, forms connecting rob bushing 3 inner hole walls and vertical direction and has angle; Make milling cutter 5 can directly process inner conical surface; Add man-hour, need process at twice, only can process the half the of inner conical surface at every turn.
Junction in said frock base 1 and said vertical portion 4 is provided with slot to make way, guarantees that workpiece clamp 2 and workpiece clamp 2 two adjacent surfaces fit tight with the end face of frock base 1 and the vertical side of portion 4 respectively.
Hole on the said workpiece clamp 2 is located at the centre position of workpiece clamp 2 length directions.
Said workpiece clamp 2 tilts towards the direction of said slot to make way.
Be provided with on the said frock base 1 with said workpiece clamp 2 on the hole that is connected, hole, hold milling cutter 5 and insert.
In use, connecting rob bushing 3 is placed in the hole of workpiece clamp 2, fixation workpiece clamp 2 is on frock base 1; Milling cutter 5 levels move to connecting rob bushing 3 positions, move downward the processing of carrying out connecting rob bushing 3 inner conical surfaces again, process half inner conical surface after; Milling cutter 5 withdraws from, and pulls down workpiece clamp 2, workpiece clamp 2 is horizontally rotated 180 degree be fixed on the frock base 1 again; Milling cutter 5 moves downward the processing of carrying out connecting rob bushing 3 second half inner conical surfaces again, until processing complete inner conical surface.
This processing tool adopts said structure, through this device connecting rob bushing 3 is carried out clamping, when processing connecting rob bushing 3 inner conical surfaces; It is skewed that connecting rob bushing 3 promptly is, and can directly process with 5 pairs of connecting rob bushings 3 of milling cutter, simple to operate; Working (machining) efficiency is high, and connecting rob bushing 3 machining accuracies are high.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
