Abstract

The utility model discloses a diamond edge wheel welding fixture comprising a base plate and a pressing plate. Mutually-corresponding stepped holes are distributed in the lower surface of the base plate and the upper surface of the pressing plate respectively, and return springs are arranged in the stepped holes between the base plate and the pressing plate. Compression bolts penetrate the stepped holes of the base plate and pass the return springs, and then each return spring is compressed via a compression nut; each compression nut is disposed in each stepped hole of the pressing plate, and then the bottom end of each compression bolt is enabled to extend to the upper surface of the pressing plate. Threaded holes are distributed in the pressing plate, through holes corresponding to the threaded holes are distributed in the base plate, a guide bolt penetrates the corresponding through hole and a pre-tightening spring to be connected in the corresponding threaded hole of the pressing plate, and center holes are formed in the centers of the base plate and the pressing plate. Being of the structure, the diamond edge wheel welding fixture is reliable in fixation and firm in welding, welding precision is greatly improved due to the action of automatic adjustment, operation time is reduced, processing efficiency is improved, and quality is guaranteed.

Description

Diamond edge-abrasive wheel weld jig

Technical field

The utility model relates to a kind of diamond edge-abrasive wheel weld jig, belongs to Machining Technology field.

Background technology

Diamond is because hardness is very high, in grinding industry, be used widely in recent years, but due to the specific purpose tool as grinding, also make diamond edge-abrasive wheel be difficult to processing and manufacturing, traditional diamond edge-abrasive wheel is adding man-hour, all on matrix, to be milled with cannelure, diamond helical teeth plate is placed in cannelure, then needs to weld with tooth of tooth of copper, adopts such processing mode, weld interval is long, manufacture difficulty is large, and working (machining) efficiency is low, and not prison welding is solid, poor welding quality, the accuracy of manufacture is also difficult to guarantee.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of diamond edge-abrasive wheel weld jig that can reduce manufacture difficulty, improve working (machining) efficiency and crudy.

In order to solve the problems of the technologies described above, diamond edge-abrasive wheel weld jig of the present utility model, comprise a base plate and a pressing plate, on the lower surface of base plate and be placed with respectively the shoulder hole of mutual correspondence on the upper surface of pressing plate, back-moving spring is placed in the shoulder hole between base plate and pressing plate; Hold-down bolt is compressed back-moving spring by a clamp nut after back-moving spring through the shoulder hole of base plate, and clamp nut makes the bottom of hold-down bolt stretch to the upper surface of pressing plate after being placed in the shoulder hole of pressing plate; On pressing plate, be placed with screwed hole, be placed with the through hole corresponding with screwed hole on base plate, guide blot is connected in the screwed hole of pressing plate after passing through hole and a preloading spring, and the center of described base plate, pressing plate is provided with centre bore.

Adopt after above-mentioned structure, due to the welding fixture special arranging, in use only need to be with clamping screw by base plate, pressing plate and substrate carry out locking positioning, due to the back-moving spring arranging between base plate and pressing plate and the hold-down bolt that coordinates with back-moving spring, by back-moving spring and the hold-down bolt interaction arranging, each compressed diamond helical teeth version flatness is adjusted automatically, not only make thus it fix reliable but also improve greatly because self-adjusting effect makes welding precision, reduced the operating time, improved working (machining) efficiency, while firm welding, make quality have guarantee.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model diamond edge-abrasive wheel weld jig.

Fig. 2 is the package assembly schematic diagram of the utility model diamond edge-abrasive wheel weld jig.

The specific embodiment

As shown in Figure 1, diamond edge-abrasive wheel weld jig of the present utility model, comprise a base plate 3 and a pressing plate 4, on the lower surface of base plate 3 and be placed with respectively the shoulder hole of mutual correspondence on the upper surface of pressing plate 4, back-moving spring 5 is placed in the shoulder hole between base plate 3 and pressing plate 4; Hold-down bolt 6 is compressed back-moving spring 5 by a clamp nut 10 after back-moving spring 5 through the shoulder hole of base plate, and clamp nut 10 makes the bottom of hold-down bolt 6 stretch to the upper surface of pressing plate 3 after being placed in the shoulder hole of pressing plate; On pressing plate 4, be placed with screwed hole, be placed with the through hole corresponding with screwed hole on base plate 3, after guide blot 9 passes through hole and a preloading spring 11, be connected in the screwed hole of pressing plate 3, the center of base plate 3, pressing plate 4 is provided with centre bore 12.

Using method as shown in Figure 2,

First base plate 3 and pressing plate 4 are assembled according to illustrated method, before adjusting, namely in the situation that preloading spring 11 does not play elastic reaction, the upper surface of pressing plate 3 is stretched out in the bottom of hold-down bolt 6, after adjustment is complete, under the elastic force effect of preloading spring 11 by the pitch enlargement between base plate 3 and pressing plate 4, make the bottom of hold-down bolt 6 be positioned at pressing plate 3 upper surfaces under, make thus pressing plate 4 keep a plane;

Secondly, again diamond helical teeth plate 2 is arranged along pressing plate 4 circumferential edges, after deploying, discoid matrix 1 is pressed in to the top of diamond helical teeth plate 2, clamping screw 7 is fastening by locking nut 8 through pressing plate 3 and discoid matrix 1 from the upper surface of base plate 4, make thus the bottom of hold-down bolt 6 stretch out the upper surface of pressing plate 3 and be pressed on the lower surface of diamond helical teeth plate 2, under the effect of back-moving spring 5, each hold-down bolt 6 can compress all helical teeth plates simultaneously simultaneously.

Locking effect due to clamping screw, three is well combined, bottom due to hold-down bolt is pressed on diamond helical teeth plate simultaneously, the active force of the spring between base plate and pressing plate is pressed on diamond helical teeth plate pressing plate further diamond helical teeth plate to be located, when occurring that each diamond helical teeth plate is not at grade time, each spring can adjust under the effect of its spring force to guarantee that all diamond helical teeth plates can both be pressed in disk shaped base voluntarily, without one by one diamond helical teeth plate being compressed to operation, thereby greatly improved working (machining) efficiency, also guaranteed positional precision.
