Description

Technical Field

[0001] The invention relates to the technical field of element detection devices, and more specifically to a wheel hub bearing plane spline riveting mechanism. Background Art

[0002] Wheel hub bearings are key components on vehicles that carry loads and provide precise guidance for wheel rotation. In recent years, the vehicle industry has developed rapidly, and higher and higher requirements have been placed on wheel hub bearings in terms of lightweight, miniaturization, low noise and high reliability. Traditional wheel hub bearings can no longer fully meet market demand and will eventually be gradually eliminated by the market. A face spline wheel hub bearing product with the advantages of lightweight, high torque transmission capacity, easy installation and maintenance, and high reliability is being widely concerned and developed, especially in the vehicle field. It has a broad market space. At present, traditional riveting equipment is generally used in conjunction with a rivet head with a toothed structure to rivet the spline tooth shape on the wheel hub bearing plane.

[0003] In most riveting mechanisms, the direction of the rivet head is fixed, and the processing position is positioned by moving the processing assembly as a whole, which requires a large space for movement of the device.

When rotating at a low speed, the load of the motor will increase, causing unnecessary energy waste.

By providing an electromagnet, the connection relationship between the connecting box 104 and the working box 105 can be controlled by controlling whether the electromagnet is energized, so that when the working box 105 rotates, the rotation of the rivet head 125 can be accelerated, so that the speed variation range of the rivet head 125 is wider.

[0033] See also Figure 2 and Figure 3 The wheel hub fixture 2 includes a placement plate 201 fixedly connected to the protection box 3, and a plurality of movable grooves 204 are arranged on the placement plate 201, and a movable block 202 is slidably connected to each movable groove 204, and a clamping block 203 is fixedly connected to one end of each movable block 202 away from the processing component 1, and a connecting plate 6 206 is fixedly connected to one end of the movable block 202 away from the processing component 1, and a connecting block 205 is fixedly connected to one end of the connecting plate 6 206 away from the movable block 202. By setting the clamping block 203, the surface of the clamping block 203 is made of rubber material, so that the clamping block 203 can clamp the wheel hub bearing while reducing the influence of the clamping on the wheel hub bearing.

[0034] See also Figure 2 and Figure 3 The placing plate 201 is internally rotatably connected to a rotating plate 208. Two cylinders 209 are arranged on the side of the rotating plate 208 away from the processing assembly 1. The cylinder 209 is fixedly connected to the protective box 3.

[0035] Specifically, when the staff places the wheel hub bearing on the placement plate 201, the cylinder 209 is started, and the cylinder 209 controls the telescopic rod 210 to retract. When the telescopic rod 210 retracts, it drives the connecting plate 6 206 to move. Through the connecting rod 207, all the connecting plates 6 206 can move at the same time. The movement of the connecting plate 6 206 drives the clamping block 203 to move synchronously through the moving block 202, so that the clamping block 203 can clamp the wheel hub bearing. At the same time, the surface of the clamping block 203 is made of rubber material, so that the clamping block 203 can clamp the wheel hub bearing while reducing the damage to the wheel hub bearing caused by the clamping.

[0036] See also Figure 4 The lifting assembly 6 includes a protective shell 602 fixedly connected to the protective box 3, and the protective shell 602 is internally rotatably connected to a threaded rod 603, and the end of the threaded rod 603 away from the hub clamp 2 is fixedly connected to the output end of a motor 601, and the motor 601 is fixedly connected to the threaded rod 603.

[0037] Specifically, when the wheel hub bearing is clamped and the processing component 1 is positioned, the motor 601 is started, and the motor 601 controls the threaded rod 603 to rotate. The rotation of the threaded rod 603 can drive the moving block 604 to move in a straight line, so that the processing component 1 moves synchronously with the moving block 604, ensuring the movement trajectory of the processing component 1 while driving the processing component 1 to move downward to apply pressure to the rotary rivet head 125.

[0038] See also Figure 6 and Figure 7 , one end of the rotating rod 106 away from the motor 102 is fixedly connected to a rotating plate 121, and one end of the rotating plate 121 away from the rotating rod 106 is fixedly connected to two connecting plates 107, a connecting column 108 is rotatably connected between the connecting plates 107, a rotating column 109 is rotatably connected at the center of the connecting column 108, and both ends of the rotating column 109 are rotatably connected to connecting plates 111, one end of the connecting plate 111 away from the rotating rod 106 is fixedly connected to the connecting plate 1 10, and one end of the connecting plate 110 away from the connecting plate 111 is fixedly connected to the rotating shaft 116, and the inner side of the rotating shaft 116 is fixedly connected to the rotating shaft 117. By arranging the connecting column 108 and the rotating column 109, when the connecting box 104 is deflected, the rotating column 109 can drive the connecting plate 111 to rotate on the connecting column 108, so that the connecting plate 111 and the connecting box 104 are always in a parallel state, thereby preventing the connecting box 104 from deflecting when it is offset.

[0039] See also Figure 6 and Figure 7One end of the rotating shaft 117 away from the rotating shaft 116 is fixedly connected to a connecting plate 4 118, one end of the connecting plate 4 118 away from the rotating shaft 117 is fixedly connected to two connecting plates 3 115, a rotating column 139 is rotatably connected between the connecting plates 3 115, a connecting column 137 is rotatably connected at the center of the rotating column 139, both ends of the connecting column 137 are fixedly connected to connecting plates 5 119, one end of the connecting plate 5 119 away from the connecting column 137 is fixedly connected to a rotating plate 122, one end of the rotating plate 122 away from the connecting plate 5 119 is fixedly connected to a bevel gear 120, and the bevel gear 120 is located inside the working box 105.

[0040] See also Figure 6 and Figure 7 , a half gear 112 is provided on the side of each connecting plate 2 111 away from the rotating shaft 116, and the half gear 112 is rotatably connected to the moving box 103, and a half gear 114 is meshed on the side of each half gear 112 away from the rotating rod 106, and the half gear 114 is rotatably connected to the connecting box 104, and the half gear 112 and the half gear 114 are fixedly connected with a rotating shaft on the side away from the rotating rod 106, and the rotating shaft passes through the moving box 103 and the connecting box 104 respectively, and the side of the rotating shaft away from the rotating shaft 116 is rotatably connected with a fixed plate 113, and the fixed plate 113 is fixedly connected to the fixed sleeve 101, and one end of the rotating shaft away from the rotating shaft 116 is fixedly connected with the output end of the motor, and the motor is located inside the fixed sleeve 101. By setting the motor, the rotation of the connecting plate 2 111 can be controlled by the motor, and then the deflection angle of the connecting box 104 and the moving box 103 can be controlled, thereby completing the positioning of the rotary rivet head 125.

[0041] Specifically, when the wheel hub bearing is clamped, the motor is started, and the motor startup controls the connection plate 2 111 to rotate. The rotation of the connection plate 2 111 causes the half gear 114 to rotate synchronously, thereby driving the connection box 104 to deflect. During the deflection, the connection column 108 is connected to the rotating column 109, and the gear 2 136 is connected to the connection column 137, so that the connection box 104 can still maintain a vertical downward state, so that when the connection box 104 drives the working box 105 to deflect, the orientation of the working box 105 remains unchanged, thereby ensuring that the force direction of the rotary rivet head 125 is always vertically downward, preventing the rotary rivet head 125 from tilting and applying force, causing the spline to rotate. The force during the riveting process is uneven, and when the rivet head 125 completes the positioning, the staff will start the motor 102, and the motor 102 will drive the rotating rod 106 to rotate. The rotation of the rotating rod 106 will drive the rotating plate 121 to rotate synchronously, and then drive the connecting plate 107 to rotate. The rotation of the connecting plate 107 will drive the connecting plate two 111 to rotate, and then drive the rotating shaft 116 to rotate through the connecting plate one 110. The rotation of the rotating shaft 116 will drive the rotating shaft one 117 to rotate synchronously. The rotation of the rotating shaft one 117 will drive the connecting plate four 118 to rotate synchronously, and then drive the rotating plate one 122 to rotate. The rotation of the rotating plate one 122 will drive the bevel gear 120 to rotate synchronously.

[0043] See also Figure 8 , Fig. 9 and Fig.10The end of the bevel gear 120 away from the connecting box 104 is rotatably connected with a fixed block 123, and the fixed block 123 is fixedly connected to the working box 105. A ratchet is provided on the side of the fixed block 123 close to the bevel gear 2 128, and the ratchet is meshed with the bevel gear 2 128. A bevel gear 3 130 is provided inside the rotating block 138, and the bevel gear 3 130 is fixedly connected to the rotating shaft 2 133. The end of the bevel gear 3 130 away from the rotating shaft 2 133 is rotatably connected with a fixed block 131, and the fixed block 131 is fixedly connected to the rotating block 138. Several bevel gears 4 132 are meshed on the outside of the bevel gear 3 130, and the bevel gears 4 132 are all rotatably connected with the fixed block 131.

A rivet head 125 is fixedly connected to the center of the tool chuck 124.

[0044] Specifically, after the bevel gear 120 rotates, it will drive the bevel gear 1 126 to rotate synchronously. When the rivet head 125 needs to move at a low speed, the motor 102 is controlled to rotate forward. At this time, the electromagnet is in a powered-on state, and the connecting box 104 is fixedly connected to the working box 105. The rotation of the bevel gear 126 will drive the bevel gear 1 126 and the bevel gear 2 128 to rotate synchronously.

At this time, the electromagnetic clutch will be powered off, so that the gear 134 will not rotate synchronously with the bevel gear 2 128, thereby causing Gear 2 136 will not rotate, so that the rotating block 138 is in a fixed state, thereby ensuring the stability of the rivet head 125 when working. When the working rivet head 125 needs to be switched, the electromagnetic clutch is energized so that the gear 134 rotates synchronously with the bevel gear 2 128, and then the rotating block 138 is driven to rotate through the gear 2 136 to complete the switching of the working rivet head 125. When the motor 102 is reversed, the electromagnet is in a power-off state, and the connecting box 104 is connected to the working box 105 in rotation. The reverse rotation of the motor 102 will drive the bevel gear 120 to rotate, and the ratchet will limit the reverse rotation of the bevel gear 2 128, so that the reverse rotation of the bevel gear 120 will drive the working box 105 to reverse as a whole, thereby completing the high-speed rotation of the rivet head 125 and improving the stability of the rivet head 125 when it rotates at high speed.

[0045] The working principle of the present invention is as follows: when the staff places the wheel hub bearing on the placement plate 201, the cylinder 209 is started, and the cylinder 209 controls the telescopic rod 210 to shrink. When the telescopic rod 210 shrinks, it drives the six connecting plates 206 to move, and through the connecting rod 207, all the six connecting plates 206 can move at the same time. The movement of the six connecting plates 206 drives the clamping block 203 to move synchronously through the moving block 202, so that the clamping block 203 can clamp the wheel hub bearing. At the same time, the surface of the clamping block 203 is made of rubber material, so that the clamping block 203 can clamp the wheel hub bearing while reducing the damage to the wheel hub bearing caused by the clamping. When the wheel hub bearing is clamped, the motor is started, and the motor startup controls the two connecting plates 1 11 is rotated, the connecting plate 2 111 rotates to make the half gear 114 rotate synchronously, thereby driving the connecting box 104 to deflect. During the deflection, through the rotation connection between the connecting column 108 and the rotating column 109, and the rotation connection between the gear 2 136 and the connecting column 1 137, the connecting box 104 can still maintain a vertical downward state, so that when the connecting box 104 drives the working box 105 to deflect, the orientation of the working box 105 remains unchanged, thereby ensuring that the force direction of the rivet head 125 is always vertically downward, preventing the rivet head 125 from tilting and applying force, resulting in uneven force on the spline during the rivet process. When the rivet head 125 is positioned, the staff will start the motor 102, and the motor 102 will drive the rotating rod 106 to rotate. The rotation of the rotating rod 106 will drive the rotating plate 121 to rotate synchronously, and then drive the connecting plate 107 to rotate. The rotation of the connecting plate 107 will drive the connecting plate 2 111 to rotate, and then drive the rotating shaft 116 to rotate through the connecting plate 110. The rotation of the rotating shaft 116 will drive the rotating shaft 117 to rotate synchronously. The rotation of the rotating shaft 117 will drive the connecting plate 4 118 to rotate synchronously, and then drive the rotating plate 122 to rotate. The rotation of the rotating plate 122 will drive the bevel gear 120 to rotate synchronously. After the bevel gear 120 rotates, it will drive the bevel gear 126 to rotate synchronously. When the rivet head 125 needs to move at a low speed, the control motor 102 is rotated forward. At this time, the electromagnet is in a power-on state, and the connecting box 104 and the working box 105 are connected. The bevel gear 126 is fixedly connected, and the rotation of the bevel gear 126 will drive the bevel gear 126 and the bevel gear 2 128 to rotate synchronously. The rotation of the bevel gear 126 will drive the gear 135 to rotate through the belt 127, and then drive the bevel gear 4 132 to rotate synchronously through the bevel gear 3 130. The tool chuck 124 is rotated by the rotation of the bevel gear 4 132, and then the rivet head 125 is controlled to rotate. The rotation of the bevel gear 2 128 will drive the shaft 1 to rotate synchronously. At this time, the electromagnetic clutch will be powered off, so that the gear 134 will not rotate synchronously with the bevel gear 2 128, and then the gear 2 136 will not rotate, so that the rotating block 138 is in a fixed state, thereby ensuring the stability of the rivet head 125 when working. When the rivet head 125 needs to be switched,By energizing the electromagnetic clutch, the gear 134 rotates synchronously with the bevel gear 128, and then the gear 136 drives the rotating block 138 to rotate, completing the switching of the working rivet head 125. When the motor 102 is reversed, the electromagnet is in a power-off state, and the connecting box 104 is connected to the working box 105. The reverse rotation of the motor 102 will drive the bevel gear 120 to rotate, and the ratchet will limit the reverse rotation of the bevel gear 128, so that the reverse rotation of the bevel gear 120 will drive the working box 105 to reverse as a whole, thereby completing the high-speed rotation of the rivet head 125 and improving the stability of the rivet head 125 when it rotates at high speed.
