Description

Technical Field

[0001] This utility model relates to the field of brake disc processing technology, and in particular to a drilling tool for brake discs. Background Technology

[0002] In numerous industrial sectors such as automobiles and mechanical transmissions, brake discs play a crucial role as key safety components. Through interaction with the friction pads on the brake caliper, the brake disc converts the vehicle's kinetic energy into heat energy, thereby achieving deceleration and braking. Its performance directly affects the vehicle's safety, stability, and braking efficiency. Drilling fixtures are typically used during the machining of brake discs.

[0003] As disclosed in prior art patent application number CN202320126802.1, an integrated tooling for brake processing is provided. After drilling the brake disc, the first motor drives the turntable to rotate at a certain angle to reposition the drilling position. No manual operation is required, the positioning is accurate, and it is convenient to continue drilling. When a certain through hole needs to be processed a second time, the first motor controls the forward or reverse rotation angle of the turntable to quickly switch the through hole that needs to be processed a second time to the bottom of the hole opening assembly.

[0004] However, the above method cannot guarantee that the brake disc is centered, which will affect the drilling effect. Utility Model Content

The aforementioned solution solves the technical problem in the prior art that it is impossible to ensure that the placed brake disc is in a centered position, thus affecting the drilling effect.

[0021] In this specific embodiment, the frame 101 is used to place on the ground for support and to improve stability, and the placement member 102 is used to place the brake disc to be processed.

[0022] The frame 101 has two sliding grooves 121 and two recesses 122. The first support 103 and the second support 104 are slidably connected to the two sliding grooves 121. The force-bearing supports 106 are slidably connected to the two recesses 122. Two centering members 105 are respectively disposed on the first support 103 and the second support 104. One end of the round rod 108 is fixedly connected to the force-bearing support 106, and the other end of the round rod 108 passes through the first support 103 and is fixedly connected to the second support 104. Both ends of the spring 107 are fixedly connected to the first support 103 and the force-bearing support 106, respectively. The lifting assembly is disposed on the frame 101, the power assembly is disposed on the lifting assembly, and the clamping assembly is connected to the power assembly. In specific use, by pressing the... The brake disc is placed on the placement member 102. The power unit is started, and the power unit drives the force-bearing bracket 106 and the first bracket 103 to move relative to each other. The force-bearing bracket 106 drives the second bracket 104 to move through the two round rods 108. At this time, the first bracket 103 and the second bracket 104 move towards each other. The first bracket 103 and the second bracket 104 drive the two centering members 105 to center and align the brake disc on the placement member 102. Then, the lifting assembly is started, and the lifting assembly drives the power unit away from the force-bearing bracket 106 and the first bracket 103. Then, the power assembly drives the clamping assembly to press the brake disc. This method solves the technical problem in the prior art that it is impossible to ensure that the placed brake disc is in a centered position, thus affecting the drilling effect.

[0023] Secondly, the dual-axis motor 109 is mounted on the lifting assembly. The output end of the dual-axis motor 109 is fixedly connected to the elliptical plate 110. The elliptical plate 110 is in contact with both the force-bearing bracket 106 and the first bracket 103. By starting the dual-axis motor 109, one of the output ends of the dual-axis motor 109 drives the elliptical plate 110 to rotate. The elliptical plate 110 abuts against the force-bearing bracket 106 and the first bracket 103, causing them to move relative to each other.

[0024] Meanwhile, the cylinder 111 is mounted on the frame 101, and the output end of the cylinder 111 is fixedly connected to the support plate 112. The dual-axis motor 109 is mounted on the support plate 112. By starting the cylinder 111, the cylinder 111 drives the support plate 112 to move, and the support plate 112 drives the dual-axis motor 109 to move, thereby driving the elliptical plate 110 away from the force-bearing support 106 and the first support 103.

By starting the dual-axis motor 109, the output end of the dual-axis motor 109 away from the elliptical plate 110 drives the rod 113 to rotate, the rod 113 drives the slide rod 114 to rotate, the slide rod 114 drives the screw 115 to rotate through the transmission unit, and the screw 115 drives the clamping member 117 to move down to clamp the brake disc.

[0026] Furthermore, the transmission unit includes a drive wheel 118, a belt 119, and a driven wheel 120. Both the drive wheel 118 and the driven wheel 120 are rotatably connected to the frame 101, and the drive wheel 118 and the driven wheel 120 are fixedly connected to the slide rod 114 and the screw 115, respectively. The belt 119 is disposed between the drive wheel 118 and the driven wheel 120. When the slide rod 114 rotates, it drives the drive wheel 118 to rotate. The drive wheel 118 drives the driven wheel 120 to rotate through the belt 119, which in turn drives the screw 115 to rotate.

[0027] Using the drilling fixture of this invention for brake discs, in specific use, the brake disc to be processed is placed on the placement member 102, and the power unit is started. The power unit drives the force-bearing bracket 106 and the first bracket 103 to move relative to each other. The force-bearing bracket 106 drives the second bracket 104 to move through the two round rods 108. At this time, the first bracket 103 and the second bracket 104 move towards each other. The first bracket 103 and the second bracket 104 drive the two centering members 105 to center and align the brake disc on the placement member 102.

Then, the power assembly drives the clamping assembly to press the brake disc. This method solves the technical problem in the prior art that it is impossible to ensure that the placed brake disc is in a centered position, thus affecting the drilling effect.
