Description

Technical Field

[0001] The utility model relates to the technical field of sealing bushing processing, in particular to a grooving device for the inner side wall of a sealing bushing. Background Technique

[0002] A sealing bushing is a component used for bearings. Its function is to protect the bearings from the intrusion of dust, moisture and other pollutants, while maintaining the grease or lubricating oil inside the bearings and extending the service life of the bearings. Grooving the inner side wall of the sealing bushing is a machining process aimed at manufacturing grooves on the inner side wall of the bushing. For some bushings, the grooving is carried out after being installed on the workpiece. For example, one end of a part of the transmission rear axle of an automobile is a cylindrical end and the other end is a special-shaped end. When grooving the bushing on such a workpiece, in some cases, a fixture on a lathe is used to clamp the cylindrical end of the transmission rear axle, and a straight grooving tool is used to groove the bushing inside the special-shaped end. The waste chips generated by grooving will splash everywhere under the rotation of the workpiece, causing the working environment to be dirty and messy. When grooving with the workpiece rotating horizontally, some of the waste chips inside the bushing will remain inside the bushing, affecting the grooving. Moreover, only one end of the workpiece is clamped, making the workpiece prone to offset during rotation, affecting the grooving effect of the bushing and being inconvenient to use.

[0022] Please refer to Figures 1 to 6, in the embodiment of the present utility model, a grooving device for the inner side wall of a sealing shaft sleeve includes a grooving mechanism 10. The grooving mechanism 10 includes a base 11. A limiting plate 12 is rotatably connected to the top of the base 11. A straight grooving tool 121 and a clamping seat 123 are movably arranged on one side of the limiting plate 12. Two clamping blocks 124 are slidably connected inside the clamping seat 123. Two protective shells 13 are slidably connected to the top of the base 11. A fixed seat 14 is fixedly connected to one side of the limiting plate 12. A clamping plate 141 is rotatably connected to the top of the fixed seat 14. Three arc-shaped blocks 142 for clamping the transmission rear axle body 20 are slidably connected to the top of the clamping plate 141. A regulation module 15 for synchronously regulating a plurality of arc-shaped blocks 142 is arranged inside the fixed seat 14. A driving module 16 for synchronously driving the two protective shells 13 is arranged on the top of the base 11.

[0023] Specifically, by slidably connecting two protective shells 13 to the top of the base 11, using the two clamping blocks 124 to clamp the special-shaped end of the transmission rear axle body 20, the transmission rear axle body 20 is made more stable during rotary grooving, and the clamped transmission rear axle body 20 is rotated to a vertical state by the limiting plate 12, so that the waste chips can automatically fall, reducing the residue of waste chips on the inner wall of the shaft sleeve, making the shaft sleeve grooving smoother. The two protective shells 13 cooperate to block and collect the waste chips splashed by the rotation of the transmission rear axle body 20, making the working environment cleaner.

[0024] Embodiment 1

[0025] As Figures 1 - 6 shown, in this embodiment, a collecting plate 131 is fixedly connected to the inner wall of the protective shell 13. Two baffle plates 132 are fixedly connected to the top of the collecting plate 131. A regulating ring 133 is rotatably connected to the outer wall of the protective shell 13. The regulating ring 133 penetrates the protective shell 13 and is fixedly connected to the collecting plate 131. A plug rod 134 is slidably connected to the outer wall of the protective shell 13. The bottom end of the plug rod 134 can be movably clamped with the regulating ring 133. A spring 135 is fixedly connected between the plug rod 134 and the protective shell 13. The driving module 16 includes two limiting support arms 161 slidably connected to the top of the base 11. The top end of the limiting support arm 161 is fixedly connected to the outer wall of the adjacent protective shell 13. A protective plate 162 is fixedly sleeved on the outer wall of the limiting support arm 161. A two-way lead screw two 164 is rotatably connected to the top of the base 11. The two-way lead screw two 164 penetrates the two limiting support arms 161. The adjacent segments of the limiting support arm 161 and the two-way lead screw two 164 are in threaded connection. A motor two 163 is fixedly connected to one side of the base 11. The output end of the motor two 163 penetrates the base 11 and is fixedly connected to the two-way lead screw two 164. A receiving groove 111 is opened on the top of the base 11. Hydraulic rods 122 are rotatably connected to the two inner walls of the receiving groove 111. The output end of the hydraulic rod 122 is rotatably connected to the limiting plate 12.

[0026] In this embodiment, the collecting plate 131 collects the waste chips splashed from the inside of the driving rear axle body 20, and the baffle plate 132 prevents the waste chips from falling out by themselves. When the insertion rod 134 is clamped with the adjusting ring 133, the collecting plate 131 cannot rotate, so as to store the waste chips. Pull up the insertion rod 134 and pull it out of the insertion rod 134. The collecting plate 131 can be rotated. After the baffle plate 132 is not flush with the end face of the adjusting ring 133, the waste chips can be manually toggled and taken out. After the two ends of the driving rear axle body 20 are clamped, start the two hydraulic rods 122 to adjust the driving rear axle body 20 to a vertical state. Start the second motor 163 to drive the bidirectional lead screw 164 to rotate. Through the bidirectional lead screw 164, start the two limiting arms 161 to approach synchronously until the two protective shells 13 are in contact with each other. The two protective shells 13 cooperate to block the waste chips splashed when the driving rear axle body 20 rotates, and collect the waste chips to the top of the collecting plate 131. The waste chips directly falling inside the shaft sleeve pass through the fixing seat 14 and fall on the top of the base 11. The accommodating grooves 111 are used to install and limit the two hydraulic rods 122, and at the same time are used to accommodate the hydraulic rods 122. Start the two hydraulic rods 122 synchronously, and the limiting plate 12 can be driven to rotate from the horizontal state to the vertical state.

[0027] As Figures 2 - 5 shown, in this embodiment, a limiting seat 125 is fixedly connected to one side of the limiting plate 12. The limiting seat 125 is movably clamped with the clamping seat 123. A bidirectional lead screw 126 is rotatably connected inside the clamping seat 123. The bidirectional lead screw 126 penetrates through the two clamping blocks 124, and the clamping blocks 124 are screwed to the adjacent segments of the bidirectional lead screw 126.

[0028] During specific implementation, rotate the bidirectional lead screw 126 from the outer end to drive the two clamping blocks 124 to approach each other, clamp the special-shaped end of the driving rear axle body 20, and rotate and limit the clamping seat 123 through the limiting seat 125, so that the rotational limit of the driving rear axle body 20 is more stable, and the cutting grooves of the inner wall shaft sleeves at both ends of the driving rear axle body 20 are more stable.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, in order to stably clamp the cylindrical end of the driving rear axle body 20, and the waste chips generated during the shaft sleeve cutting can fall through the fixing seat 14, preventing them from remaining inside the fixture and affecting the use.

[0031] As Figures 1 - 3As shown, in this embodiment, three limit rods 143 are slidably connected inside the fixed seat 14, and the top of the limit rod 143 is fixedly connected to the adjacent arc block 142. The regulating module 15 includes a chuck 151 rotatably connected to the inside of the chuck 141, and a plurality of slots 152 are equidistantly provided on the outer wall of the chuck 151. A plurality of arc grooves 153 are equidistantly provided on the top of the chuck 151. The limit rod 143 passes through the adjacent arc grooves 153 and is movably engaged with them. A fixing screw 154 is screwed on the outer wall of the chuck 141, and one end of the fixing screw 154 can be movably engaged with the adjacent slot 152. An inner gear ring 155 is fixedly connected to the bottom of the chuck 141, and a motor 156 is fixedly connected to the inside of the fixed seat 14. A gear 157 is fixedly sleeved on the output end of the motor 156, and the gear 157 is meshed with the inner gear ring 155.

[0032] In a specific implementation, the fixed seat 14 limits the limit rod 143 to achieve the sliding limit of the arc block 142. The three arc blocks 142 move synchronously to clamp the cylindrical end of the transmission rear axle body 20. When one of the arc blocks 142 is moved, the arc block 142 is moved by the clamping connection between the limit rod 143 and the arc groove 153 to drive the chuck 151 to rotate. The chuck 151 drives the limit rod 143 to move through the remaining arc grooves 153, so that multiple arc blocks 142 are synchronously close to the transmission rear axle body. The cylindrical end of the body 20 is clamped. After clamping, the fixing screw 154 is rotated to clamp it into the adjacent slot 152, thereby limiting the position of the chuck 151 and the multiple arc blocks 142. The driving motor 156 can drive the gear 157 to rotate, and the transmission of the gear 157 and the inner gear ring 155 drives the chuck 141 to rotate as a whole, driving the clamped transmission rear axle body 20 to rotate, and cooperating with the straight cutting tool 121 to cut grooves on the inner wall sleeves at both ends of the transmission rear axle body 20.
