5results about How to "No deviation" patented technology

The utility model discloses a durable composite contact, which comprises a base body, a first rectangular space is arranged in the lower surface of the base body, a second rectangular space is arranged in the top wall of the first rectangular space, a rectangular moving block can be just clamped in the second rectangular space, a contact is fixedly arranged at the upper part of the rectangular block, and the lower part of the base body is provided with a second rectangular space. A contact layer which penetrates through the top wall of the second rectangular space, extends out and is slidably connected to the base body is arranged at the upper end of the contact, a fixing plate is arranged on the top wall of the first rectangular space, a bolt penetrates through and is rotatably connected to the fixing plate, and the fixing plate is in direct threaded connection with a moving block through the bolt; the up-down movement of the moving block can be limited, so that the contact layer is prevented from shaking due to vibration; and meanwhile, rotation of the bolt is limited through the clamping block, so that the condition that the contact layer deviates due to wrong rotation of the bolt is avoided, and the stability of the contact layer is ensured.

The utility model discloses a polaroid mirror bracket for fine angle adjustment, which belongs to the field of polaroid mirror brackets and comprises a mirror bracket main body, an angle scale is arranged on the mirror bracket main body, and an inner mounting sleeve is arranged in the mirror bracket main body. The driven outer teeth are arranged on the adjusting plate and used in cooperation with the fine adjustment driving structure, rotation adjustment of the driven outer teeth and the adjusting plate is carried out through a driving gear in the fine adjustment driving structure, speed reduction adjustment is carried out through the gear transmission ratio, the situation that the angle adjustment is too large due to excessive rotation of the adjusting plate can be effectively avoided, and the use effect of the polaroid is guaranteed; through the arrangement of the limiting driving assembly, the spring, the pressing plate and the rubber pad, in the adjusting process, the limiting driving assembly drives the driving rod, the pressing plate and the rubber pad to move and give way, then the angle is adjusted through rotation, the adjusting plate is reset under the action of the spring after adjustment, and the rubber pad on the pressing plate is pressed on the adjusting plate to achieve the pre-fixing effect; and it is ensured that the position does not deviate during follow-up fixing and locking.

The utility model relates to a drilling machine for integrated circuit board production belongs to integrated circuit board production technical field, including base, drilling machine, driver and positioner, the surface fixed connection of base has control panel, the surface fixed connection of base has four placing rack, the inner wall rotation is connected with rotating wheel in four placing racks, the inner wall fixed connection of rotating wheel has four mounting bracket, the surface of base is equipped with collecting device, the surface of base is equipped with auxiliary device, the collecting device includes two slide plates. The utility model discloses through being provided with collecting device, can drive circuit board and the surface contact of the adhesion layer while rotating wheel rotation replaces the circuit board that needs drilling, removes the debris on the circuit board surface as far as possible through the adhesion layer while driving the operation of conveyer belt, has facilitated the processing use of back, and has improved the quality of circuit board, makes the subsequent processing not because the debris on the surface appears influence.

This invention relates to a fully automatic CNC circular saw for pipe cutting, belonging to the field of automation equipment technology. It includes a worktable, an operation panel mounted on top of the worktable, a discharge channel inside the worktable, a support cover mounted on one side of the operation panel, a feeding trough located in the middle of the side of the operation panel near the support cover, a discharge trough located on top of the operation panel, and an electric slide rail mounted on the side of the operation panel away from the support cover. A top plate is mounted on the moving end of the electric slide rail. This invention, by setting up a feeding component, can quickly adapt to the support and positioning of circular pipes of different diameters, automatically calculate and position the cutting length, improving the accuracy and efficiency of fixed-length cutting; by setting up a fixing component, the circular pipe is fixed from multiple directions, eliminating shaking and offset during cutting, significantly improving the flatness and dimensional accuracy of the cut.

This invention provides a turbine blade tipping fixture and tipping method. The tipping fixture includes a support unit, a clamping unit, a locking unit, and an angle adjustment unit. The support unit includes a column, and the clamping unit includes a carrier and a blade clamping member that accommodates and clamps the turbine blade. A pressure plate is detachably connected to the carrier. The pressure plate and set screw of the locking unit limit and press the blade clamping member into the U-shaped portion of the carrier. The angle adjustment unit includes a rotating shaft and a knob. The rotating shaft passes through the column, and the knob is connected to one end of the rotating shaft on one side of the column. The carrier is connected to the other end of the rotating shaft on the other side of the column. The rotating shaft drives the carrier and the blade clamping member to rotate. Using this tipping fixture and method, the turbine blade is fixed and the grinding wheel position is moved back and forth during tipping repair, improving the tipping field of vision. During the tipping process, the condition of the blade tip thin blade area can be accurately judged, and the relative position of the blade and the grinding wheel can be adjusted at any time to remove material evenly, thus improving the repair quality and efficiency.
