A tooling for machining the shaft grooves at both ends of an idler roller

Abstract

A fixture for machining the shaft grooves at both ends of an idler roller includes a fixed plate, fixed blocks, and movable blocks. Two fixed blocks are fixed to the middle and one near one end of the fixed plate. Each fixed block has a V-shaped groove. Two parallel sliding grooves are formed along the length of the fixed plate at its other end. Two sliders are connected to the bottom of the movable block, which is slidably connected to the sliding grooves on the fixed plate via the sliders. Each movable block has a U-shaped groove. The idler roller is placed on the V-shaped groove of the fixed block and the U-shaped groove of the movable block. This invention utilizes the cooperative positioning of the sliding movable block and the fixed block, and the sliding groove structure enables rapid adjustment. The complementary nature of the V-shaped and U-shaped grooves ensures the consistency of the flat groove machining at both ends of the idler roller, improving the machining quality of the shaft grooves at both ends of the idler roller.

Description

Technical Field

[0001] This utility model relates to the field of shaft groove machining tooling, and in particular to a tooling for machining shaft grooves at both ends of an idler roller. Background Technology

[0002] Idler rollers are core components of conveying equipment, and the machining accuracy of their end grooves directly affects the assembly quality and service life of the idler rollers. Traditional idler roller groove machining often uses fixed tooling, usually consisting of a pair of fixed "V"-shaped support blocks used to clamp the idler roller and position it for machining. However, the fixed "V" groove spacing of traditional tooling cannot be adapted to the machining of idler rollers of different lengths, resulting in frequent tooling changes when machining products of different specifications, leading to low efficiency. Moreover, when machining the flattened ends of the idler rollers, one end is usually milled first, and then the other end is milled. However, the symmetry and flatness of the flattened ends can often only be estimated visually, resulting in poor uniformity and affecting the installation quality. Summary of the Invention

[0003] This utility model aims to address the shortcomings of the existing technology by providing a tooling for machining the shaft grooves at both ends of an idler roller.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A tooling for machining the shaft grooves at both ends of an idler roller includes a fixed plate, a fixed support block, and a movable support block. A fixed support block is fixed at the middle position of the fixed plate and at one end near the fixed plate. The fixed support block has a "V" shaped groove. The other end of the fixed plate has two parallel sliding grooves along the length of the fixed plate. The bottom of the movable support block is connected to two sliders. The movable support block is slidably connected to the sliding groove of the fixed plate through the sliders. The movable support block has a "U" shaped groove. The idler roller is placed on the "V" shaped groove of the fixed support block and the "U" shaped groove of the movable support block.

[0006] The fixed support block includes a fixed support block body and fixed side plates. A "V" shaped groove is formed in the upper middle part of the fixed support block body. The two fixed side plates are integrally connected to the bottom sides of the fixed support block body. Two first bolt holes are formed on the fixed side plates.

[0007] The “V”-shaped groove includes a vertical first groove wall and a “V”-shaped groove bottom wall, with the vertical first groove wall connected to the top of the “V”-shaped groove bottom wall.

[0008] The movable support block includes a movable support block body, movable side plates, and two sliders. A "U"-shaped groove is formed in the upper middle part of the movable support block body. The two movable side plates are integrally connected to the bottom sides of the movable support block body. Two second bolt holes are formed on the movable side plates.

[0009] The "U"-shaped groove includes a vertical second groove wall and an arc-shaped groove bottom wall, with the vertical second groove wall connected to the top of the arc-shaped groove bottom wall.

[0010] The fixing plate has several fixing bolt holes evenly distributed on both sides of the slide groove.

[0011] The spacing between adjacent fixing bolt holes is the same as the spacing between the two first bolt holes and the two second bolt holes.

[0012] The beneficial effects of this utility model are: This utility model uses a sliding moving block and a fixed block for coordinated positioning, and utilizes a groove structure to achieve rapid adjustment. Combined with the complementarity of "V" shaped grooves and "U" shaped grooves, it ensures the consistency of the flat groove processing at both ends of the idler roller and improves the processing quality of the shaft grooves at both ends of the idler roller.
