Description

Technical Field

[0001] This utility model relates to the field of brake rings, specifically an adjustable brake ring clamping assembly. Background Technology

[0002] Brake rings cast using sand molds often lack certain necessary processing, so they often need to be placed in a CNC machining center for further processing. During this process, a clamping mechanism is required to fix the brake ring, ensuring that the CNC machining center's cutting tools can accurately process the brake ring.

[0003] Most existing clamping mechanisms are fixed clamping types. However, the brake ring has a closed-loop structure, and its surface needs to be processed 360 degrees in a CNC machining center. Since the existing clamping mechanisms are fixed, when processing different angles on the brake ring, it is necessary to release the clamp, change the clamping angle, and then clamp it again before continuing to process different parts of the brake ring with the tool. This greatly increases the workload and reduces the processing efficiency. Therefore, it is necessary to develop an adjustable brake ring clamping component to solve the shortcomings of the existing technology. Utility Model Content

[0024] Example 1

[0025] like Figures 1 to 5 As shown, an adjustable brake ring clamping assembly includes a clamping frame 1 and an extension frame 2 integrally formed on its upper and lower sides. The front of the clamping frame 1 is provided with a plurality of evenly distributed clamping components 4, which clamp a brake ring 3. The interior of the clamping frame 1 is provided with a plurality of evenly distributed limiting grooves 5, with each clamping component 4 corresponding to one of the limiting grooves 5. The rear end of each clamping component 4 slides into the limiting groove 5. A tensioning component 6 is embedded in the back of the clamping frame 1, and a transmission belt 7 is provided on the back of the clamping frame 1. The transmission belt 7 drives... The clamping frame 1 is fitted onto the tensioning assembly 6 and several clamping assemblies 4. An adjusting air pump 8 is fixedly installed on the back of the clamping frame 1. The output end of the adjusting air pump 8 is connected to several pneumatic components. The several pneumatic components correspond one-to-one with the clamping assemblies 4 and are connected to each other. With the cooperation of the tensioning assembly 6 and the transmission belt 7, the clamping assemblies 4 can be driven to rotate simultaneously under the restriction of the adjusting air pump 8 and the pneumatic components, thereby changing the clamping surface between them and the brake ring 3, and at the same time changing the contact surface between the brake ring 3 and the clamping assemblies 4, so as to process different parts of the clamping surface of the brake ring 3.

[0026] The clamping assembly 4 clamps the anti-slip sleeve 41 on the surface of the brake ring 3. The drive shaft 42 is fixedly sleeved inside the anti-slip sleeve 41. The rear end of the drive shaft 42 passes through the anti-slip sleeve 41 and extends through the limiting groove 5 to the back of the clamping frame 1 and is fixedly connected to the first pulley 43. The first pulley 43 is driven and sleeved inside the drive belt 7. The outer surface of the drive shaft 42 is fixedly sleeved with a limiting shaft 44 that is slidably engaged inside the limiting groove 5. Due to the setting of the limiting shaft 44, the pneumatic components can drive the clamping assembly 4 to reciprocate along the direction of the limiting groove 5 with the cooperation of the limiting groove 5, thereby clamping brake rings 3 of different sizes.

[0027] The pneumatic assembly consists of a sealing tube 9, a telescopic rod 10, a linkage ring 11, and a connecting tube 12. The sealing tube 9 is fixedly installed on the back of the clamping frame 1. One end of the telescopic rod 10 is sealed and fitted inside the sealing tube 9, and the other end of the telescopic rod 10 is fixedly connected to the linkage ring 11. The linkage ring 11 is rotated and fitted onto the outer surface of the first pulley 43 through a bearing. One end of the connecting tube 12 is connected to the output end of the regulating air pump 8, and the connecting tube 12 is connected between the regulating air pump 8 and the sealing tube 9.

[0028] The sealing pipe 9, telescopic rod 10, and linkage ring 11 are located on the front and back sides of the limiting slide groove 5. The axes of the sealing pipe 9, telescopic rod 10, and linkage ring 11 are parallel to the axis of the limiting slide groove 5. A pneumatic valve is installed inside the end of the connecting pipe 12 that connects to the sealing pipe 9. Due to the pneumatic valve, the overall position of the sealing pipe 9, telescopic rod 10, and linkage ring 11 can be changed by adjusting the air pump 8 in cooperation with the connecting pipe 12, so as to facilitate the clamping of brake rings 3 of different specifications or even different shapes by the clamping assembly 4.

[0029] The tensioning assembly 6 includes a slot 61 on the back of the clamping frame 1 and the extension frame 2. A second pulley 62 located outside the slot 61 is provided on the back of the clamping frame 1 and the extension frame 2. The second pulley 62 is driven and sleeved inside the transmission belt 7. A second knob 68 is fixedly connected to the back of the second pulley 62. Due to the setting of the second knob 68, the operator can easily rotate the second pulley 62, thereby causing several first pulleys 43 to rotate simultaneously under the drive of the transmission belt 7. This causes the anti-slip sleeve 41 to drive the brake ring 3 to rotate, thereby changing the clamping point of the clamping assembly 4 on the brake ring 3.

[0030] The front of the second pulley 62 is rotatably connected to a linkage slider 63 that is slidably engaged inside the slot 61 via a bearing. Inside the slot 61, an adjusting slider 64 located above the linkage slider 63 is also slidably engaged. A buffer spring 65 connects the linkage slider 63 and the adjusting slider 64. Due to the setting of the buffer spring 65, under the action of its elastic restoring force, it is ensured that when the adjusting slider 64 moves, it can be engaged with several first pulleys 43, and the transmission belt 7 can be tightened by the linkage slider 63 and the second pulley 62, thereby ensuring that when the second knob 68 is turned, it can drive several clamping components 4 to rotate via the transmission belt 7.

[0031] The slot 61 is equipped with a lead screw 66. The lower end of the lead screw 66 is rotatably connected to the bottom of the slot 61 through a bearing. The upper end of the lead screw 66 passes through the slot 61 and extends to the top of the extension frame 2 and is fixedly connected to the first knob 67.

[0032] The lead screw 66 passes through the interior of the linkage slider 63, and the lead screw 66 is threaded into the interior of the adjusting slider 64. Due to the lead screw 66, when the lead screw 66 is rotated by the first knob 67, it can drive the adjusting slider 64 to move under the restriction of the slot 61. In turn, with the cooperation of the buffer spring 65, the linkage slider 63 is pulled, thereby tightening the transmission belt 7 with the cooperation of the second pulley 62.

[0033] Example 2

[0034] Assemble the equipment as shown in the figure, place the brake ring 3 on the front of the clamping frame 1, and then start the regulating air pump 8 to drive several clamping components 4 to move through several pneumatic components, so that the clamping components 4 clamp the outer surface of the brake ring 3 or abut against the inside of the brake ring 3.

[0035] When it is necessary to process both the inner and outer sides of the brake ring 3 at the same time, first process the arc surface that is not clamping point, and then rotate the second knob 68 to drive several clamping components 4 to rotate through the second pulley 62 and the transmission belt 7, so that the clamping point of the anti-slip sleeve 41 on the brake ring 3 is changed, and the original clamping point can be processed.
