Description

Technical Field

[0001] The utility model belongs to the technical field of bearing ring processing, and more specifically, particularly relates to a precision bearing ring processing device. Background Technique

[0002] A bearing ring is an annular ring inside and outside a bearing. The bearing ring goes through multiple processes such as heat treatment and lathe processing. The higher the precision requirement of the bearing ring, the stricter the processing flow.

[0003] After the turning processing of the bearing ring is completed, it falls and rolls along an inclined track. However, during the turning processing, metal chips will fall on the track, resulting in the collision between the processed bearing ring falling and the metal chips, and the collision between the metal residue and the falling bearing ring generates scratch marks, which affects the qualified rate of later detection. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a precision bearing ring processing device to solve the problem that after the turning processing of the bearing ring is completed, it falls and rolls along an inclined track. However, during the turning processing, metal chips will fall on the track, resulting in the collision between the processed bearing ring falling and the metal chips, and the collision between the metal residue and the falling bearing ring generates scratch marks. If the scratch marks are too deep, they cannot be repaired by later polishing. For the strict grade division of the surface roughness of the precision bearing ring, it will affect the qualified rate of later detection.

[0005] The purpose and effect of a precision bearing ring processing device of the utility model are achieved by the following specific technical means:

[0006] A precision bearing ring processing device includes a rotary processing shaft member; a discharge guiding frame is arranged below the rotary processing shaft member; a piston member is arranged above the discharge guiding frame; a lower base is fixed below the rotary processing shaft member, an upper sliding frame is fixed above the lower base, a moving tool holder slides on the top of the upper sliding frame, and the moving tool holder is moved by a motor through a gear rack or a lead screw. A lower rotating frame is fixed below the lower base.

[0007] Further, an upper guiding plate rotates above the discharge guiding frame, an outer connecting spring rotates on the outer cylinder of the upper guiding plate, an upper connecting slider rotates on the outer side of the tail of the discharge guiding frame, a tail support column is slidably connected below the upper connecting slider, an upper screw rotates on the upper connecting slider, and a tail guiding plate is arranged at the tail of the discharge guiding frame.

[0008] Further, the tail end of the outer connecting tension spring is rotatably connected to the outer cylinder of the discharge guiding frame. The lower part of the upper screw rod is screwed to the tail support column. The tail guiding plate is located below the upper guiding plate. By rotating the upper screw rod, the external thread of the upper screw rod guides the axial movement of the tail support column. The length of the tail support column extending out of the lower part of the upper connecting slider is reduced, the height of the tail of the discharge guiding frame is lowered, and the tail of the discharge guiding frame rotates obliquely around the lower rotating frame.

[0009] Further, the upper guiding plate is located between the rotary processing shaft part and the moving tool rest, and the upper guiding plate is located below the rotary processing shaft part and the moving tool rest. The discharge guiding frame is rotatably connected to the lower rotating frame. The discharge guiding frame and the upper guiding plate are tilted synchronously to guide the processed bearing ring to roll along the inclined upper guiding plate towards the tail guiding plate.

[0010] Further, an inner piston slides inside the piston part. The tail of the inner piston is communicated with a one-way air inlet. A one-way valve body is arranged inside the one-way air inlet. The front part of the piston part is communicated with a one-way air outlet. A one-way valve body is arranged inside the one-way air outlet. The one-way air outlet is communicated with the air outlet box through a hose.

[0011] Further, the air outlet box is fixed to the upper part of the discharge guiding frame. The air outlet box is located below the rotary processing shaft part. The inner piston is fixedly connected to the moving tool rest. When the moving tool rest approaches the rotary processing shaft part side, the moving tool rest and the compressed inner piston move synchronously. The moving tool rest drives the inner piston and the piston part to be compressed. The one-way air outlet discharges air. The one-way air outlet transports the air flow to the air outlet box through a hose.

[0012] Further, the outer connecting tension spring pulls the upper guiding plate to be inclined to one side. The air outlet box is located above the upper guiding plate. The air outlet box blows the metal residues on the top of the upper guiding plate to move towards the lower side.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. After the bearing ring processed by the utility model falls on the upper guiding plate, the upper guiding plate moves downward and pulls the outer connecting tension spring to buffer the impact force of the falling bearing ring, reduce the situation of bearing sleeve falling damage, and improve the qualified rate of precision detection of the bearing sleeve.

[0015] 2. The utility model adjusts the inclination angle of the discharge guiding frame towards the tail by the extending lengths of the tail support column and the upper connecting slider to adapt to the docking of transportation equipment with different heights.

[0016] 3. The utility model compresses the inner piston by the movement of the moving tool rest, and the air outlet box discharges air to clean the metal residues remaining on the top of the upper guiding plate, avoiding the situation that the metal residues remaining on the top of the upper guiding plate collide with the falling bearing ring to produce scratch marks.

[0032] Specific usage mode and function of this embodiment:

[0033] In the present utility model, the rotary processing shaft part 1 clamps the bearing ring to be processed, and the bearing rings rotate synchronously. The moving tool holder 103 approaches the bearing ring along the upper slide 102, and the moving tool holder 103 performs turning processing on the bearing ring. After the bearing ring is processed, the rotary processing shaft part 1 no longer clamps the bearing ring, and the processed bearing ring falls downward onto the upper guide plate 201. The upper guide plate 201 moves downward and pulls the outer connecting tension spring 202 to extend to buffer the impact force of the falling bearing ring, reduce the situation of damage to the bearing ring due to falling, and improve the qualified rate of precision detection of the bearing ring;

[0034] When the moving tool rest 103 approaches the rotary machining shaft part 1, the moving tool rest 103 and the compression inner piston 301 move synchronously.

The one-way air outlet 303 conveys the air flow to the air outlet box 304 through a hose. The middle opening of the air outlet box 304 discharges air towards the upper guide plate 201 to clean the metal residues remaining on the top of the upper guide plate 201, and blows the metal residues on the top of the upper guide plate 201 to one side. The outer connecting pull spring 202 pulls the outside of the upper guide plate 201 to a lower height, and the upper guide plate 201 is arranged with a gradually decreasing height from the inner side of the discharge guide frame 2 to the outside, so that the air outlet box 304 blows the metal residues on the top of the upper guide plate 201 to move towards the lower side, avoiding the situation that the metal residues remaining on the top of the upper guide plate 201 collide with the falling bearing rings and generate scratch marks; when the moving tool rest 103 moves away from the rotary machining shaft part 1, the moving tool rest 103 and the compression inner piston 301 move synchronously. The moving tool rest 103 drives the inner piston 301 and the piston part 3 to expand. The inner piston 301 inhales gas from the one-way air inlet 302. The one-way air inlet 302 faces away from the side far from the rotary machining shaft part 1 to prevent metal scraps from entering the one-way air inlet 302.

[0035] By rotating the upper screw rod 204, the external thread of the upper screw rod 204 guides the axial movement of the tail support column 203. The length of the tail support column 203 extending out of the lower part of the upper connecting slider 205 decreases. The discharge guide frame 2 rotates obliquely around the lower rotating frame 104. The height of the tail of the discharge guide frame 2 decreases, and the inclination angle of the discharge guide frame 2 increases. The inclination angle of the discharge guide frame 2 towards the tail is adjusted. The discharge guide frame 2 and the upper guide plate 201 tilt synchronously to guide the processed bearing rings to roll along the inclined upper guide plate 201 towards the tail guide plate 206, and finally roll to a collection pool or a transfer and conveying device such as a belt, adjusting the fixing speed of the bearing rings and adjusting the heights of the tail of the discharge guide frame 2 and the tail guide plate 206 to adapt to the docking of transfer devices at different heights.
