Abstract
The invention discloses a device for locking a screw on an upper end cover of an automotive compressor, which comprises a torque gun; and the device is characterized in that the device also comprises an upper press table, a lower press table, a locking pin, connecting pieces and a positioning column, wherein the torque gun sequentially passes through the centers of the upper press table and the lower press table, three sliding chutes are arranged in the lower press table, the connecting pieces which can move are respectively arranged in the sliding chutes, the bottoms of the connecting pieces are connected with the positioning column passing through the lower press table, and a thread hole which is formed in the locking pin inwards and passes through the side wall of the lower press table is connected with the connecting pieces. The invention solves the problems that in the prior art, when a screw is locked on an upper end cover of an automotive compressor, the screw is easy to swing, so that a dislocation phenomenon is caused and brings big difficulties to locking, and meanwhile, because the sizes of the locking positions are different, different positioning tools are required for positioning the locking positions of various compressors, thereby increasing the production costs of enterprises. Therefore, the invention provides a device for locking a screw on an upper end cover of an automotive compressor, which is simple in structure and convenient to use, and can quickly position the locking position and keep the locking position still.
Description
Technical field
The present invention relates to a kind of lock screw device, particularly relate to a kind of vehicle compressor upper end cover lock screw device.
Background technology
Vehicle compressor is most important parts in the automobile making, and can its quality is directly connected to automobile normal operation.Present vehicle compressor is after upper end cover assembles, need to be at upper end cover by the torque gun lock screw, during torque gun locking upper end cover screw, must guarantee that upper end cover keeps stable, the lock screw effect is better like this, can not cause owing to dislocation the damage of compressor upper end cover.Simultaneously different compressors is owing to varying in size, and its locked position size is also different, needs different orientation tools that the locked position of various compressors is positioned, and needs like this to make more orientation tool, has increased the production cost of enterprise.
Summary of the invention
Easily rock when solving in the prior art vehicle compressor upper end cover lock screw, cause dislocation, bring larger difficulty to locking, because the locked position size is also different, need different orientation tools that the locked position of various compressors is positioned simultaneously, increased the problem of enterprise's production cost, the invention provides a kind of simple in structure, easy to use, can the Rapid positioning locking position, and keep its motionless vehicle compressor upper end cover lock screw device.
In order to address the above problem, the technical solution used in the present invention is:
A kind of vehicle compressor upper end cover lock screw device, comprise torque gun, it is characterized in that: also comprise upper holder, bottom platen, locking pin, contiguous block and locating dowel, described torque gun is passed the center of upper holder and bottom platen successively, in bottom platen, be provided with three chutes, be respectively arranged with the contiguous block that can move in chute, be connected with the locating dowel of passing bottom platen in the bottom of contiguous block, described locking pin passes the screwed hole that the bottom platen sidewall inwardly offers and links to each other with contiguous block.
Aforesaid a kind of vehicle compressor upper end cover lock screw device, it is characterized in that: be symmetrically arranged with four guide pillars in the upper holder bottom, described four guide pillars stretch into bottom platen, and can pass bottom platen.
Aforesaid a kind of vehicle compressor upper end cover lock screw device is characterized in that: in the outside of each guide pillar, be provided with spring between upper holder and bottom platen.
Aforesaid a kind of vehicle compressor upper end cover lock screw device, it is characterized in that: described three locating dowel length are identical.
The invention has the beneficial effects as follows: vehicle compressor of the present invention upper end cover lock screw device clamps locked position by three locating dowels, has guaranteed that locked position can not rock in the lock screw process, and processing effect is better.Simultaneously the present invention can slide by before and after locking pin control connection piece is in the bottom platen chute, and the space of such three locating dowel clampings can be adjusted, and the vehicle compressor of applicable different sizes uses, and versatility is better.
Description of drawings
Fig. 1 is vehicle compressor of the present invention upper end cover lock screw device structural representation.
Fig. 2 is that vehicle compressor of the present invention upper end cover lock screw device is without the bottom platen structural representation.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of vehicle compressor upper end cover lock screw device, comprise torque gun 1, upper holder 2, bottom platen 3, contiguous block 4, locating dowel 5 and locking pin 6, described torque gun 1 is passed the center of upper holder 2 and bottom platen 3 successively, be provided with three chutes in 3 pressing down, in chute, be respectively arranged with the contiguous block 4 that can move, be connected with the locating dowel 5 of passing bottom platen in the bottom of contiguous block 4, described locking pin 6 passes the screwed hole that the bottom platen sidewall inwardly offers and links to each other with contiguous block 4.
Be symmetrically arranged with four guide pillars 7 in upper holder 2 bottoms, described four guide pillars 7 stretch into bottom platen 3, and can pass bottom platen 3.In the outside of each guide pillar 7, between upper holder 2 and bottom platen 3, be provided with spring 8.During design, three locating dowel 5 length are identical.
In sum, vehicle compressor of the present invention upper end cover lock screw device clamps locked position by three locating dowels 5, has guaranteed that locked position can not rock in the lock screw process, and processing effect is better.Simultaneously the present invention can rotate control connection piece 4 front and back in the bottom platen chute by locking pin 6 and slide, and the space of such three locating dowel 6 clampings can be adjusted, and the vehicle compressor of applicable different sizes uses, and versatility is better.The present invention is provided with spring 8 between upper holder 2 and bottom platen 3 in addition, can play cushioning effect by spring 8, has guaranteed the quality of processing, and after machining, can pass through spring 8 self-returns.
Above demonstration and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
