Description

Technical Field

[0001] This application belongs to the field of hanging device technology, specifically relating to a lower core chuck device with adjustable clamping range. Background Technology

[0002] The manufacturing process of brake discs mainly includes two stages: casting and finishing. During casting and finishing, the discs need to be handled on the production line. Some parts of the production line are in high-temperature environments. If the discs are handled manually, it could cause burns and pose a safety hazard. Moreover, brake discs in some fields are large and heavy, requiring several people to move them, resulting in high labor costs, a significant waste of human resources, and substantial safety risks.

[0003] To address the issue of brake disc handling during production, a brake disc tilting lifting device was authorized on August 9, 2024, with authorization number CN221500348U. This device includes a clamping assembly, a gripper assembly, a scissor telescopic assembly, and a locking assembly. Before clamping the brake disc, the locking assembly is in a locked state, locking the first and second lifting arm assemblies. This fixes the distance between the clamping ends of the first and second clamping arms, making it greater than the diameter of the brake disc being clamped. When the lifting device moves to the brake disc position, the first and second lifting arms rotate, causing the fixed cylinder to rise synchronously. This, in turn, drives the locking rod to rotate via a transmission mechanism, unlocking the locking rod and releasing the lock between the first and second lifting arm assemblies. As the lifting arm assemblies continue to rotate, the clamping ends of the first and second clamping arms gradually approach and clamp the brake disc.

[0004] This patent can clamp the brake disc, and the distance between the two clamping ends is adjustable, making it suitable for brake discs of different outer diameters. However, during the hoisting process, the brake disc is only clamped by the two clamping ends, and there is no restraining force on the top of the brake disc. This makes it easy for the brake disc to shake, tilt, or even fall during the hoisting process, posing a significant safety hazard. Summary of the Invention

[0046] The following detailed description of a lower core clamping claw device with adjustable clamping range, in conjunction with the accompanying drawings, is not intended to limit the scope of this application.

[0047] A lower core clamping claw device with adjustable clamping range, consisting of... Figures 1 to 3 As shown, the device includes a telescopic control device 1 and vertical rods 7 arranged on both sides of the telescopic control device 1. Each vertical rod 7 is equipped with a connecting device 8, which supports and engages the bottom and sidewalls of the brake disc. Therefore, for a more secure engagement, each side of the telescopic control device 1 has at least two spaced vertical rods 7.

[0048] The telescopic control device 1 has a telescopic rod 101 that controls the movement of at least one vertical rod 7 on one side. In this embodiment, the telescopic rods 101 on both sides move towards or away from each other simultaneously.

[0049] The insertion device 8 includes an insertion plate 801, which is arranged inwards on the vertical rod 7. A lifting device connector 2 is provided at the top of the telescopic control device 1, and the lifting device connector 2 is connected to the lifting device.

[0050] In use, the lifting device lifts the lower core chuck device to the brake disc blank or core material. The telescopic control device 1 controls the extension of the telescopic rod 101 and the opening of the insert plate 801. Then, the telescopic rod 101 retracts, the insert plate 801 approaches and locks onto the bottom of the brake disc blank or core material, completing the gripping of the brake disc blank or core material. Afterward, the lifting device moves the material away.

[0051] To accommodate brake discs of different thicknesses, the position of the insertion device 8 on the vertical rod 7 needs to be adjustable vertically. Therefore, this application provides the following two arrangements:

[0052] Method 1:

[0053] The insertion device 8 is slidably connected to the vertical rod 7. A positioning device is provided between the insertion device 8 and the vertical rod 7. After the insertion device 8 slides to the designated position, it is fixed by the positioning device.

[0054] Method 2:

[0055] The vertical rod 7 is a threaded rod, and the insertion device 8 is threadedly connected to the vertical rod 7. The insertion device 8 includes an insertion plate 801, and a nut sleeve 802 is fixed on the outside of the insertion plate 801. The nut sleeve 802 is sleeved on the vertical rod 7 and threadedly connected to the vertical rod 7.

[0056] Depend on Figure 11 As shown, the nut sleeve 802 is provided with a threaded hole, the axial direction of the threaded hole is arranged perpendicular to the axial direction of the nut sleeve 802, and a first locking bolt 803 is threadedly connected inside the threaded hole.

[0057] To achieve more precise adjustment and to ensure that the angle of the insert plate 801 is adjustable, and that the insert plate 801 does not rotate during use, this application adopts the structure described in Method 2 above.

[0058] The tops of the two vertical rods 7 on one side of the telescopic control device 1 are fixedly connected to a connecting plate 6, which is connected to the telescopic rod 101.

[0059] The connecting plate 6 is connected to the telescopic rod 101 via the second mounting plate 5. The connecting plate 6 has a protruding slider 601, and the second mounting plate 5 has two opposing clamping plates 501 below it. The slider 601 is slidably disposed between the two clamping plates 501.

[0060] The card plate 501 is provided with a positioning cavity 502, and a second locking bolt 9 is inserted inside the positioning cavity 502. The slider 601 is provided with a threaded hole on its side, and the second locking bolt 9 is threadedly connected to the threaded hole.

[0061] The positioning cavity 502 can adopt an oblong hole to facilitate the adjustment of the position of the slider 601, thereby adjusting the position of the connecting plate 6 and the vertical rod 7, expanding the range of applications.

[0062] The second mounting plate 5 is detachably connected to the vertically arranged first mounting plate 4 by bolts. The first mounting plate 4 has two through holes, which are fitted onto the telescopic rod 101. In this embodiment, the telescopic rod 101 has a threaded part, on which two positioning nuts 3 are threadedly connected. The first mounting plate 4 is engaged between the two positioning nuts 3.

[0063] Relying solely on the plug-in device 8 to clamp the brake disc cannot guarantee that the brake disc will not shake during hoisting. If the clamping force of the plug-in device 8 is insufficient, the brake disc will inevitably shake during hoisting. If the clamping force of the plug-in device 8 is too large, the brake disc will jump up, both of which pose safety hazards.

[0064] To avoid the aforementioned safety hazards, the telescopic control device 1 is equipped with an upper top seat 10 that slides vertically at its bottom, and the upper top seat 10 is linked to the telescopic rod 101. When the plug-in device 8 clamps the brake disc, the upper top seat 10 presses down on the brake disc to achieve multi-point positioning of the brake disc and ensure stability during hoisting.

[0065] This application achieves the linkage between the upper seat 10 and the telescopic rod 101 in the following two ways:

[0066] The first option is as follows:

[0067] Depend on Figures 4 to 6 As shown, the telescopic control device 1 has a displacement cavity 103 inside, and a piston 102 is slidably disposed inside the displacement cavity 103. The piston 102 is fixedly connected to the telescopic rod 101.

[0068] The telescopic control device 1 has a telescopic cavity 107 arranged vertically below it. The telescopic cavity 107 is connected to the displacement cavity 103. A vertical rod 11 is slidably arranged inside the telescopic cavity 107. A spring seat 1101 is fixed at the top of the vertical rod 11. The lower part of the vertical rod 11 passes through the telescopic cavity 107 and is fixedly connected to the upper top seat 10. A spring 12 is sleeved on the vertical rod 11. The upper and lower ends of the spring 12 abut against the spring seat 1101 and the bottom surface of the telescopic cavity 107, respectively.

[0069] The displacement cavity 103 is located between the two pistons 102 and is filled with hydraulic oil. The telescopic control device 1 is equipped with a drive assembly, which drives the piston 102 to slide along the inside of the displacement cavity 103.

[0070] The drive component can be an electrically controlled telescopic rod or a hydraulic cylinder.

[0071] In this embodiment, the drive assembly includes a hydraulic oil station located outside the telescopic control device 1. The displacement cavity 103 is connected to a front end cavity 1031 through the end. The piston 102 is larger than the front end cavity 1031. The telescopic control device 1 is provided with an inlet and outlet oil passage 108 that is connected to the front end cavity 1031 through the inside. The inlet and outlet oil passage 108 is connected to the hydraulic oil station through an external oil pipe 109.

[0072] In use, high-pressure oil flows into the inlet and outlet oil passage 108 through the external oil pipe 109, and then enters the front end cavity 1031, pushing the piston 102 inward, so that the two pistons 102 move towards each other. At this time, the telescopic rod 101 retracts, driving the plug-in device 8 to clamp the brake disc.

[0073] When the two pistons 102 move toward each other, they squeeze the hydraulic oil inside the displacement chamber 103, pressurize the hydraulic oil and inject it into the telescopic chamber 107, pushing the spring seat 1101 to overcome the thrust of the spring 12 and push the vertical rod 11 and the upper top seat 10 downward, so that the upper top seat 10 presses down on the brake disc, completing the entire clamping work of the brake disc.

[0074] When the brake disc is released, only external oil pipe 109 needs to be depressurized. Spring 12 pushes spring seat 1101 upward, squeezing out the hydraulic oil inside telescopic cavity 107, which in turn pushes piston 102 outward.

[0075] To avoid interference between the two pistons 102, in this embodiment, the telescopic control device 1 is provided with two displacement chambers 103 spaced apart, and each displacement chamber 103 contains a piston 102. A baffle ring 104 is provided inside the displacement chamber 103, which divides the interior of the displacement chamber 103 into an oil chamber 105, preventing the piston 102 from sliding into the oil chamber 105.

[0076] The oil chambers 105 inside the two displacement chambers 103 are connected by an intermediate oil passage 106, and the intermediate oil passage 106 is connected to the telescopic chamber 107 by a vertical oil passage 1061.

[0077] The second option is as follows:

[0078] Depend on Figures 7 to 10 As shown, the telescopic control device 1 has a displacement cavity 103 inside, and a piston 102 is slidably disposed inside the displacement cavity 103. The piston 102 is fixedly connected to the telescopic rod 101.

[0079] The telescopic control device 1 has a telescopic cavity 107 arranged vertically below it. The telescopic cavity 107 is connected to the displacement cavity 103. A vertical rod 11 is slidably arranged inside the telescopic cavity 107. The vertical rod 11 passes through the telescopic cavity 107 and is fixedly connected to the upper top seat 10. A first rack 13 is fixed above the vertical rod 11.

[0080] The piston 102 is fixed with a second rack 15 at one end away from the telescopic rod 101. The displacement cavity 103 is rotatably equipped with a gear 14. The shaft 1401 of the gear 14 transmits power from the telescopic control device 1 and is connected to the output shaft of the motor 16. The motor 16 is externally fixedly connected to the telescopic control device 1.

[0081] The second racks 15 connected to the pistons 102 on both sides inside the displacement cavity 103 are respectively disposed on the upper and lower sides of the gear 14. The first rack 13 is vertically arranged between the two second racks 15, and the first rack 13 and the two second racks 15 are respectively meshed with the gear 14.

[0082] In order to keep the second rack 15 parallel during the movement of the displacement cavity 103, a support end plate 1501 is provided at the end of the second rack 15, and the upper and lower ends of the support end plate 1501 abut against the upper and lower end faces of the displacement cavity 103.

[0083] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
