Background

Connecting rod hook in low-voltage apparatus switch, a steel sheet stamping workpiece, connecting rod hook middle part is bent again, an important standard of weighing connecting rod hook quality is exactly the tolerance size of the angle of bending degree, in order to avoid connecting rod hook in heat treatment process to produce deformation, I department has made a shape heat treatment frock of preapring for an unfavorable turn of events when adding man-hour, it includes long backup pad, short backup pad, bottom plate and inclined support board, and set up the fretwork hole in each backup pad, place connecting rod hook on inclined support board and short backup pad and avoid its department of bending to warp for connecting rod hook provides the support when heat treatment, but discovery in the in-service use, still there are following defects: the connecting rod hook is directly placed on an inclined plate surface, the connecting rod hook drops in the moving process of the tool, and the hollow holes are formed, but most of the bottom surface of the connecting rod hook is directly contacted with the plate surface and cannot be effectively contacted with quenching oil, so that the quenching effect of the connecting rod hook in a quenching tank is unsatisfactory, and the retention time needs to be prolonged.

Disclosure of Invention

The utility model discloses the technical problem that will solve lies in: the utility model provides a connecting rod hook thermal treatment location frock, it has solved the connecting rod hook and has come off easily and the unsatisfactory problem of quenching effect when current location frock uses.

The utility model discloses the technical problem that will solve takes following technical scheme to realize:

a connecting rod hook heat treatment positioning tool comprises a bottom plate, a long supporting plate and a short supporting plate which are parallel to each other and are fixed with the bottom plate, and an inclined supporting plate of which two ends are respectively fixed with the long supporting plate and the short supporting plate, the surface of the inclined supporting plate is provided with a plurality of first limiting grooves, the surface of the short supporting plate is provided with a plurality of second limiting grooves, the number of the second limiting grooves is the same as that of the first limiting grooves, the upper end of each first limiting groove is communicated with the tail end of one second limiting groove, the groove walls on two sides of each first limiting groove are provided with drainage grooves extending along the length direction of the first limiting groove, the groove bottom of each first limiting groove is provided with through grooves extending along the length direction of the first limiting groove, the groove walls on two sides of each second limiting groove are provided with drainage grooves extending along the length direction of the second limiting groove, the groove bottom of each second limiting groove is provided with through grooves extending along the length direction of the second limiting groove, and the drainage grooves on the second limiting grooves of the drainage grooves on the first limiting grooves are communicated with one another.

Through adopting above-mentioned technical scheme, put into the spacing groove with the connecting rod hook in the processing procedure and provide spacing for it, avoid droing, and run through groove, drainage groove and can make quenching oil and connecting rod bottom, side fully contact, ensure the quenching effect.

As a preferred example, the through hole of the first position-limiting groove is not communicated with the through hole of the second position-limiting groove.

As a preferable example, an abutting plate is further fixed to the short support plate at a lower end of each of the second limiting grooves, and the abutting plate abuts against a hook head of the link hook.

The utility model has the advantages that the connecting rod hook is placed in the limiting groove to provide limiting function for the connecting rod hook and avoid falling off, and the quenching oil of the connecting rod hook can be fully contacted by the drainage groove and the through groove to ensure the quenching effect.

fig. 3 is a view from a-a in fig. 2.

In the figure: bottom plate 1, long backup pad 2, short backup pad 3, bearing diagonal 4, first spacing groove 5, second spacing groove 6, drainage groove 7, run through groove 8, butt plate 9.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1, 2 and 3, a connecting rod hook heat treatment positioning tool comprises a bottom plate 1, a long support plate 2, a short support plate 3 and an inclined support plate 4, wherein the long support plate 2 and the short support plate 3 are parallel to each other and are fixed with the bottom plate 1, the inclined support plate 4 is fixed with the long support plate 2 and the short support plate 3 at two ends respectively, a plurality of first limiting grooves 5 are arranged on the surface of the inclined support plate 4, a plurality of second limiting grooves 6 are arranged on the surface of the short support plate 3, the number of the second limiting grooves 6 is the same as that of the first limiting grooves 5, the upper end of each first limiting groove 5 is communicated with the tail end of one second limiting groove 6, drainage grooves 7 extending along the length direction of each first limiting groove 5 are arranged on the groove walls at two sides of each first limiting groove 5, through grooves 8 extending along the length direction of each groove are arranged on the groove walls at two sides of each second limiting groove 6, the tank bottom is equipped with along its length direction extended through groove 8, and drainage groove 7 on the drainage groove 7 second spacing groove 6 on the first spacing groove 5 is linked together.

A gap is reserved between the connecting rod hook and the wall of the groove so that quenching oil can enter, the width of the penetrating groove 8 is smaller than that of the connecting rod hook and is preferably 4-12mm smaller so as to ensure that the quenching oil has enough contact surface with the connecting rod hook and provide stable support for the connecting rod hook.

Furthermore, the through hole in the first limiting groove 5 is not communicated with the through hole in the second limiting groove 6, and a continuous contact surface is formed at the bending part of the connecting rod hook, so that the supporting effect on the bending part is ensured.

Further, an abutting plate 9 is fixed to the lower end of each second limiting groove 6 on the short supporting plate 3.

The connecting rod hook is placed into the limiting groove to provide limiting effect for the connecting rod hook, the connecting rod hook is prevented from falling off, the drainage groove 7 and the penetrating groove 8 can enable the connecting rod hook fish quenching oil to be in full contact, and the quenching effect is ensured.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
