Abstract
The utility model provides a honing tool of a high-accuracy hole of a hydraulic motor cover. The honing tool is characterized by comprising a clamp body, wherein a positioning pin is arranged at the bottom of the clamp body; the clamp body is fixed on a machine tool work table through the positioning pin; a cushion plate is arranged on the top of the clamp body and is provided with a positioning cylindrical pin for positioning the hydraulic motor cover to be machined and a rhombus pin; and the hydraulic motor cover to be machined is fixed on the cushion plate through a fixed screw. After the honing tool is placed on the machine tool work table, the hydraulic motor cover to be machined is placed on the honing tool, so that an aim of honing the high-accuracy hole of the hydraulic motor cover can be fulfilled only by using the machine tool; and therefore, the production efficiency and the positioning accuracy are improved, and the production cost is reduced at the same time.
Description
Technical field
The utility model relates to a kind of honing frock that is used for hydraulic motor lid high accurate hole honing technique.
Background technology
In the manufacture process of hydraulic motor, assembled all control oil line pipes on the motor cover housing, wherein high accurate hole etc. is most important working connection.For machining accuracy and the cylindricity requirement that reaches drawing; Traditional processing technology is that this hole is after horizontal or vertical machining centre processing; Change horizontal or vertical honing machine carries out honing, this traditional processing method has many limitation, and many-side is restricting the manufacturing processing of hydraulic motor lid:
1. production efficiency is low: after the processing of horizontal or vertical machining centre, change horizontal or vertical honing machine carries out honing, prolonged process time, influenced working (machining) efficiency.
2. positioning accuracy is not high: change horizontal or vertical honing machine carries out honing, need second positioning, change has taken place in processing datum, influences machining accuracy.
3. production cost is high: this traditional diamond-making technique needs two high precision machine tools and the high-precision tool locating of two covers, has improved production cost.
Summary of the invention
The purpose of the utility model provides a kind of honing frock, can realize more fast and without the machine adding method of the motor cover housing high accurate hole of resetting through this honing frock.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of honing frock of hydraulic motor lid high accurate hole, it is characterized in that: comprise clamp body, be provided with alignment pin in the bottom of clamp body; Clamp body is fixed on the platen through alignment pin; Top at clamp body is provided with backing plate, on backing plate, is provided with in order to locate the setting circle pin and the rhombus pin of hydraulic motor lid to be processed, and hydraulic motor lid to be processed is fixed on the backing plate through hold-down screw.
Preferably, said backing plate is fixed on the top of said clamp body through lock-screw.
Preferably, said setting circle pin and said rhombus pin are fixed on the said backing plate through locking nut and packing ring.
After the honing frock that the utility model is provided is placed into platen; Again hydraulic motor lid to be processed is placed on the honing frock; Thereby only use lathe just can accomplish the honing processing that hydraulic motor is covered high accurate hole; Improve production efficiency and positioning accuracy, simultaneously, reduced production cost.
Description of drawings
A kind of hydraulic motor that Fig. 1 provides for the utility model covers the side sectional view of the honing frock of high accurate hole;
A kind of hydraulic motor that Fig. 2 provides for the utility model covers the vertical view of the honing frock of high accurate hole.
The specific embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Like Fig. 1 and shown in Figure 2; The honing frock of a kind of hydraulic motor lid high accurate hole that the utility model provides comprises clamp body 1, is provided with alignment pin 8 in the bottom of clamp body 1; Clamp body 1 is fixed on the platen through alignment pin 8; Be provided with backing plate 2 at the top of clamp body 1, backing plate 2 is fixed on the top of clamp body 1 through lock-screw 4, on backing plate 2, is provided with in order to locate the setting circle pin 5 and the rhombus pin 9 of hydraulic motor lid 10 to be processed; Setting circle pin 5 and said rhombus pin 9 are fixed on the backing plate 2 through locking nut 7 and packing ring 6, and hydraulic motor to be processed lid 10 is fixed on the backing plate 2 through hold-down screw 3.
A kind of frock that adopts the utility model to provide to the step that hydraulic motor lid high accurate hole carries out honing is:
The first step: through alignment pin 8 and bolt clamp body 1 is fixed on the platen, backing plate 2 is fixing with clamp body 1;
Second step: hydraulic motor lid to be processed is positioned on the backing plate 2 through rhombus pin 9 and setting circle pin 5, utilizes hold-down screw 3 lockings;
The 3rd step: each size of processing motor cover is to drawing requirement, and high accurate hole is reserved the honing surplus;
The 4th step: utilize the preassembled honing knife of machining center tool magazine, directly change the honing cutter and carry out high-precision honing processing, reach the cylindricity and the roughness requirement of design drawing.
