Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a brake disc grinding fixture. Background Technology

[0002] Brake discs are a key component of automotive braking systems, used to slow down or stop vehicles through friction with brake pads. Over time, brake discs may develop wear, scratches, or unevenness, all of which can affect braking performance. Grinding on a lathe can restore the flatness and smoothness of the brake disc surface. A lathe grinding fixture is a specialized tool used for machining brake discs, primarily for fixing and positioning the brake discs to facilitate precision turning and grinding operations.

[0003] In the existing brake disc grinding fixture, the brake disc is clamped by the clamping force of two pressure plates. However, due to the high-speed rotation of the rotating shaft, the brake disc is subjected to resistance and friction from the cutting tool and grinding plate, and the presence of oil stains, etc., the brake disc may strip due to insufficient friction, which will affect the final grinding effect of the brake disc. Utility Model Content

[0004] The purpose of this utility model is to provide a brake disc grinding fixture. Through the engagement of the groove and the stop rod, the engagement of the stop rod and the bearing hole of the brake disc, and the squeezing of the screw tube on the pressure tube, the brake disc can always follow the rotation of the rotating shaft. This avoids insufficient clamping force of the pressure tubes on the brake disc during grinding due to high-speed rotation, oil stains, and frictional obstruction, thus preventing the brake disc from stripping and ensuring the grinding effect.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A brake disc grinding fixture includes a rotating shaft mounted on one side of a transmission chamber. A stop bar is symmetrically fixedly connected to the outer wall of the rotating shaft.

A brake disc is slidably sleeved on the outer wall of the pressure tube. A clamping plate is fixedly connected to the outer wall of the pressure tube on one side of the brake disc. A plurality of insert rods for movably engaging with bearing holes of the brake disc are fixedly connected in an array on one side of the clamping plate. A second pressure tube is slidably sleeved on the outer wall of the rotating shaft on one side of the brake disc. An insert hole is slidably opened in an array on one side of the second pressure tube for movably engaging with the insert rods. A threaded tube is threadedly connected to one end of the rotating shaft on one side of the second pressure tube.

[0007] A cover plate is fixedly connected to one side of the transmission compartment and outside the stop bar. The cover plate has through windows on both sides for observing the stop bar.

[0008] One side of the window is fixedly connected to an indicator for providing a guide angle for the groove.

[0009] The end of the solenoid near the pressure tube is rotatably connected to a pressure plate, and the pressure plate has an array of through holes for the insert rod to be movably inserted.

[0010] The pressure tube has a symmetrical through-hole on one side, and the rotating shaft has a thread on one end.

[0011] The outer wall of the solenoid is symmetrically fixed with a rotating handle, and one end of the solenoid is provided with a clamping face.

[0012] The technical effect achieved by this utility model is as follows: through the engagement of the groove and the stop rod, the engagement of the stop rod and the bearing hole of the brake disc, and the squeezing of the screw tube on the pressure tube two, the brake disc can always follow the rotation of the rotating shaft, avoiding insufficient clamping force of the pressure tube one and pressure tube two on the brake disc due to high-speed rotation, oil stains, and friction during grinding, thus preventing the brake disc from stripping and ensuring the grinding effect.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figures 1-3As shown, a brake disc grinding fixture includes a rotating shaft 1 mounted on one side of a transmission chamber 103. One end of the rotating shaft 1 has a thread 101. A stop bar 102 is symmetrically fixedly connected to the outer wall of the rotating shaft 1. A cover plate 104 is fixedly connected to one side of the transmission chamber 103 and outside the stop bar 102. Windows 105 for observing the stop bar 102 are provided through the two sides of the cover plate 104. A pressure tube 107 is slidably sleeved on the outer wall of the rotating shaft 1. One end of the pressure tube 107 has a groove 108 for movably engaging with the stop bar 102. An indicator 106 for providing a guide angle for the groove 108 is fixedly connected to one side of the window 105. A brake disc 111 is slidably sleeved on the outer wall of the pressure tube 107. A clamping plate 1 is fixedly connected to the outer wall of the pressure tube 107 and on one side of the brake disc 111. 09. A number of insert rods 110 for movably engaging with the bearing holes of the brake disc 111 are fixedly connected in an array on one side of the clamping plate 109. A pressure tube 112 is slidably sleeved on the outer wall of the rotating shaft 1 and located on one side of the brake disc 111. A first insertion hole 113 for movably engaging with the insert rods 110 is opened in an array on one side of the pressure tube 112. A pinch hole 114 is symmetrically opened through one side of the pressure tube 112. A screw tube 115 is threadedly connected to one end of the rotating shaft 1 and located on one side of the pressure tube 112. A pressure plate 118 is rotatably connected to one end of the screw tube 115 near the first pressure tube 107. A second insertion hole 119 for movably engaging the insert rods 110 is opened through one side of the pressure plate 118. A rotating handle 117 is symmetrically fixedly connected to the outer wall of the screw tube 115. A clamping face 116 is opened at one end of the screw tube 115.

[0020] Based on the above structure, first, the pressure tube 107 is fitted onto the outer wall of the rotating shaft 1. The pressure tube 107 is slid and rotated to adjust its angle, making the groove 108 parallel to the indicator 106. The pressure tube 107 is then slid further to engage the groove 108 with the stop lever 102. The engagement can be observed and adjusted through the window 105. Next, the brake disc 111 is fitted onto the rotating shaft 1, and the brake disc 111 is nested within the outer wall of the pressure tube 107, which is one side of the clamping plate 109. The insert rods 110 are respectively engaged with the bearing holes of the brake disc 111. The clamping plate 109 blocks the brake disc 111 to prevent it from sticking to the cover plate 104. Furthermore, by pinching the pinch hole 114 with fingers, the pressure tube 112 can be inserted into the rotating shaft 1, so that the pressure tube 112 is embedded in one side of the brake disc 111. At the same time, the first fitting hole 113 is engaged with the insert rods 110. Furthermore, the threaded tube 115 is threaded to the rotating shaft 1, and the handle 1 is rotated. 17. Continuously rotate the screw tube 115 until it is close to the pressure tube 112. Rotate the pressure plate 118 until the locking hole 119 engages with one end of the locking rod 110. Then, use pliers, wrenches, or other tools to clamp the clamp face 116 and tighten the screw tube 115, preventing the pressure tube 112, brake disc 111, pressure tube 107, and other components from sliding. When the transmission structure inside the transmission chamber 103 drives the rotating shaft 1 to rotate, the rotating shaft 1 drives the pressure tube 107 to rotate via the stop rod 102. The brake disc 111 is rotated by the insert rod 110. This utility model, through the engagement of the groove 108 and the stop rod 102, the engagement of the insert rod 110 and the bearing hole of the brake disc, and the squeezing of the screw tube 115 on the pressure tube 112, can ensure that the brake disc 111 always rotates with the rotating shaft 1. This avoids insufficient holding force of the pressure tube 1 and pressure tube 2 on the brake disc due to high-speed rotation, oil stains, and friction during grinding, thus preventing the brake disc 111 from stripping and ensuring the grinding effect.

[0021] The working principle of this utility model is as follows: First, the pressure tube 107 is fitted onto the outer wall of the rotating shaft 1. The pressure tube 107 is slid and rotated to adjust its angle, so that the groove 108 is parallel to the indicator 106. The pressure tube 107 is then slid further to engage the groove 108 with the stop rod 102. The engagement can be observed and adjusted through the window 105. The brake disc 111 is then fitted onto the rotating shaft 1, and the brake disc 111 is nested on the outer wall of the pressure tube 107, which is one side of the clamping plate 109. At the same time, the stop rods 110 engage with the bearing holes of the brake disc 111. The clamping plate 109 blocks the brake disc 111, preventing it from sticking to the cover plate 104. Furthermore, the pressure tube 112 can be engaged by pinching the pinch hole 114 with fingers. Insert the rotating shaft 1, so that the pressure tube 112 is embedded in one side of the brake disc 111. At the same time, the first insertion hole 113 is engaged with the insertion rod 110. Further, the screw tube 115 is threaded to the rotating shaft 1. Rotate the screw tube 115 with the rotating handle 117 until it is close to the pressure tube 112. Rotate the pressure plate 118 so that the second insertion hole 119 is engaged with one end of the insertion rod 110. Use pliers, wrenches or other tools to clamp the clamp face 116 and tighten the screw tube 115 so that the pressure tube 112, brake disc 111, pressure tube 107 and other components can no longer slide. When the transmission structure in the transmission chamber 103 drives the rotating shaft 1 to rotate, the rotating shaft 1 drives the pressure tube 107 to rotate through the stop rod 102. The pressure tube 107 drives the brake disc 111 to rotate through the insertion rod 110.

[0022] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
