Abstract
The utility model relates to an engine oil pump body clamp, including the base and be located the base upper bracket, be fixed with A type boring sleeve through hexagon head bolt and boring sleeve screw on the support, the both sides of support are respectively set up a positioning mechanism by the back position, positioning mechanism includes the A type rotating pressing plate that is used for compressing tightly the pump body, A type rotating pressing plate one end rotates and connects on adjusting the support, and one end is pressed on the pump body, the fastening and the release to A type rotating pressing plate are realized through stud and hexagon nut to the center of A type rotating pressing plate; and the inner side of each positioning mechanism is provided with a fixed positioning pin. The pump body is fastened through the positioning mechanisms on the two sides, so that only the pump body is arranged at the stress point of the pump body, the vibration of the pump body in the stress process and the resonance generated by the positioning mechanisms can be effectively reduced, and the processing precision is obviously improved.
Description
Technical Field
The utility model relates to an anchor clamps device field specifically is an engine oil pump body anchor clamps.
Background
The oil pump body needs a special clamp during secondary processing, the prior art discloses various oil pump body clamps, and as the Chinese utility model patent CN206343925U discloses an oil pump body processing clamp, the oil pump body processing clamp comprises a circular plate, a round hole is arranged on the circular plate along the thickness direction of the circular plate, the inner edge of the round hole extends outwards to form a holding cylinder, the circular plate and the holding cylinder are divided into two parts by a plane A, and the plane A is parallel to the axis of the holding cylinder; threaded holes are formed in the side face of the circular plate, the threaded holes penetrate through the half circular plate, and fastening bolts are arranged in the threaded holes. The machine oil pump body sleeve is arranged on the clamping cylinder through the rotor cavity, the machine oil pump body can be effectively clamped, the fastening effect is good, the operation is convenient, the machining efficiency is improved, the following defects are still overcome, the pump body sleeve is arranged on the clamping cylinder through the circular plate, in the actual machining process, due to the characteristics of the motor, the force applied by the drill bit is not pure linear when the motor is driven, certain fluctuation exists, the clamping cylinder is additionally arranged on the pump body, the resonance of the pump body and the clamping cylinder in the machining process is easily caused, and the machining precision is difficult to guarantee.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a machine oil pump body anchor clamps is provided to solve the defect that exists among the prior art.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
a machine oil pump body clamp comprises a base and a support positioned on the base, wherein an A-shaped boring sleeve is fixed on the support through a hexagon head bolt and a boring sleeve screw, two positioning mechanisms are respectively arranged at the positions, close to the back, of two sides of the support, each positioning mechanism comprises an A-shaped rotating pressing plate used for pressing a pump body, one end of each A-shaped rotating pressing plate is rotatably connected to an adjusting support, the other end of each A-shaped rotating pressing plate is pressed on the pump body, and the center of each A-shaped rotating pressing plate realizes fastening and loosening of the A-shaped rotating pressing plate through the hexagon head bolt and a hexagon nut; and the inner side of each positioning mechanism is provided with a fixed positioning pin.
Further, a bushing for the boring sleeve is arranged on the outer side of the A-type boring sleeve;
furthermore, a cross washer which plays a role in buffering is arranged between the hexagonal nut and the A-shaped rotating pressure plate;
the utility model has the advantages that: the pump body is fastened through the positioning mechanisms on the two sides, so that only the pump body is arranged at the stress point of the pump body, the vibration of the pump body in the stress process and the resonance generated by the positioning mechanisms can be effectively reduced, and the processing precision is obviously improved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the structure of FIG. 1 in the direction A;
the reference numerals are explained below:
1. the device comprises a hexagon head bolt, 2, a boring sleeve screw, 3, an A-type boring sleeve, 4, a lining for the boring sleeve, 5, an adjusting support, 6, an A-type rotating pressure plate, 7, a cross washer, 8, a hexagon nut, 9, a stud bolt, 10, a fixed positioning pin, 11 and a fixed positioning pin;
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, an oil pump body clamp comprises a base and a support positioned on the base, wherein an a-shaped boring sleeve is fixed on the support through a hexagon head bolt and a boring sleeve screw, two positioning mechanisms are respectively arranged at the positions, close to the rear, of two sides of the support, each positioning mechanism comprises an a-shaped rotating pressure plate used for pressing a pump body, one end of each a-shaped rotating pressure plate is rotatably connected to an adjusting support, the other end of each a-shaped rotating pressure plate is pressed on the pump body, and the center of each a-shaped rotating pressure plate realizes fastening and loosening of the a-shaped rotating pressure plate through the hexagon head bolt and a hexagon nut; and the inner side of each positioning mechanism is provided with a fixed positioning pin.
In specific implementation, in order to reduce friction and increase buffer, a bushing for the boring sleeve can be arranged on the outer side of the A-type boring sleeve;
in specific implementation, a cross washer with a buffering function can be arranged between the hexagon nut and the A-shaped rotating pressure plate;
the specific working principle is as follows: when processing, fix the engine oil pump body both ends on the positioning mechanism of both sides, then the drill bit drills to the pump body that is located the positioning mechanism middle through the boring sleeve, because the stress point department of the pump body only has the pump body, does not have other fixing device, can effectively reduce the vibration of the pump body and the resonance of positioning mechanism rather than producing in the atress process, is showing and is improving the machining precision.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
