Description

Technical Field

[0001] This utility model relates to the field of tool shaft gap adjustment, and in particular to a tool shaft gap adjustment device. Background Technology

[0002] The double-belt flying shear is a key piece of equipment in the field of sheet metal processing for continuous shearing operations. The precise adjustment of its cutter shaft gap directly affects the shearing quality of the sheet metal and the service life of the equipment. In existing technologies, traditional cutter shaft gap adjustment devices typically employ fixed structures or simple bolt adjustments, making it difficult to achieve fast and precise gap control.

[0003] Specifically, the existing technology has the following main drawbacks:

[0004] Low adjustment efficiency: Some devices require disassembly of multiple parts or adjustment with the help of additional tools, which is cumbersome and time-consuming, and cannot meet the needs of rapid changeover or continuous operation of the production line; at the same time, the adjusted cutter shaft clearance is easily affected by factors such as equipment vibration and long-term operation and may shift.

[0005] Based on this, we propose a tool shaft gap adjustment device. Utility Model Content

[0006] To address the technical problem of low adjustment efficiency, this utility model provides a tool shaft gap adjustment device.

[0007] This utility model is achieved by the following technical solution: a tool shaft gap adjustment device, including a first connecting bracket and a second connecting bracket, wherein an adjustment mechanism is sleeved on the outer ring surface of the first connecting bracket, and a groove is opened on the outer ring surface of the second connecting bracket.

[0008] The adjustment mechanism includes a mounting bracket, which is fitted onto the outer surface of the first connecting bracket. Locking bolts are bolted to the outer surface of the mounting bracket. Adjustment cavities are formed on both sides of the mounting bracket, and adjustment frames are connected to the inner sides of these cavities. The mounting bracket and the adjustment frames are positioned together by fixing bolts. The adjustment frames pass through slots and move within the slots. Two sets of adjustment frames are provided, connected to both sides of the adjustment cavities in the adjustment mechanism.

[0009] The system includes a spacing adjustment mechanism, comprising a fastening sleeve with a U-shaped frame. A bolt at the bottom of the fastening sleeve passes through a fastening plate. The fastening sleeve and fastening plate are secured together by a nut threaded onto the frame. An integral connecting plate is formed on the outer side of the fastening plate, and a sliding sleeve is fixedly connected to the bottom of the connecting plate. A cutter disc is connected to the outer side of the sliding sleeve, and a ball bearing is installed at the connection between the cutter disc and the sliding sleeve. The sliding sleeve is fitted onto the outer ring surface of the bearing. The fastening sleeve is then fitted onto the outer ring surface of the adjusting frame via a nut, allowing the fastening sleeve to move and adjust its position on the outer ring surface of the adjusting frame.

[0010] As a further optimization of this utility model, the specific technical solution includes an adjustment cavity on both sides of the mounting bracket in the adjustment mechanism, and the adjustment frame is positioned with the mounting bracket by fixing bolts. When the fixing bolts are loosened, the adjustment frame can move left and right in the adjustment cavity, while its other end passes through the slot of the second connecting bracket and moves within the slot, thereby changing the position of the adjustment frame, realizing the adjustment of the cutting angle, and laying the foundation for subsequent adjustment of the cutter shaft gap.

[0011] As a further optimization of this utility model, the fastening sleeve of the spacing adjustment mechanism is a U-shaped frame, which is sleeved on the surface of the adjustment frame by a nut. When it is necessary to adjust the cutter shaft clearance, the nut is loosened, and the fastening sleeve can move left and right on the adjustment frame, driving the fastening plate, connecting plate and sliding sleeve at its bottom end to move synchronously.

[0012] As a further optimization of this utility model, the cutter head connected to the outer side of the sliding sleeve is connected to the sliding sleeve via a ball bearing and can rotate around the sliding sleeve. The sliding sleeve is fitted onto the bearing surface to ensure the stability of the sliding sleeve during movement. By adjusting the position of the fastening sleeve on the adjusting frame, the gap between the cutter heads can be precisely changed.

[0013] As a further optimization of this utility model, after adjusting to the target gap, the nut sleeve is tightened to fix the fastening sleeve to the adjusting frame. Simultaneously, the position of the adjusting frame in the adjusting cavity is locked by the fixing bolts, and the position of the adjusting mechanism on the first connecting bracket is fixed by the locking bolts. This multi-layered fixing structure effectively resists the effects of equipment vibration and long-term operation, prevents the cutter shaft gap from shifting, and ensures the accuracy of the shearing operation and the stability of the equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By loosening the locking bolts and fixing bolts, the adjusting frame can move within the adjusting cavity and slot without disassembling a large number of parts. This allows for quick adjustment of the adjusting frame position, laying the foundation for adjusting the cutter shaft clearance and meeting the needs of rapid changeover on the production line.

[0016] 2. By loosening the nut sleeve, the fastening sleeve can move on the adjusting frame, which drives the fastening plate and other components to change the position of the cutter head. Combined with the setting of ball bearings and bearings, the cutter shaft clearance can be precisely controlled.

[0017] 3. After adjustment, this utility model is fixed in multiple layers by nut sleeve, fixing bolt, and locking bolt, which can resist the influence of equipment vibration and long-term operation, prevent gap displacement, and ensure shearing accuracy and equipment service life.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example 1:

[0025] Please combine Figures 1-3 This embodiment proposes a tool shaft gap adjustment device, including a first connecting bracket 1 and a second connecting bracket 2. The outer ring surface of the first connecting bracket 1 is fitted with an adjustment mechanism 3, and the outer ring surface of the second connecting bracket 2 is provided with a groove 21.

[0026] The adjusting mechanism 3 includes a mounting bracket 31, which is fitted onto the outer surface of the first connecting bracket 1. Locking bolts 32 are bolted to the outer surface of the mounting bracket 31. Adjusting cavities 33 are formed on both sides of the mounting bracket 31, and adjusting frames 34 are connected to the inner sides of the adjusting cavities 33. The mounting bracket 31 and the adjusting frames 34 are positioned by fixing bolts 35. The adjusting frames 34 pass through slots 21 and move within the slots 21. Two sets of adjusting frames 34 are provided, and the two sets of adjusting frames 34 are connected to both sides of the adjusting cavities 33 in the adjusting mechanism 3.

[0027] In the specific technical solution, the mounting bracket 31 in the adjustment mechanism 3 has adjustment cavities 33 on both sides, and the adjustment frame 34 is positioned with the mounting bracket 31 by fixing bolts 35. When the fixing bolts 35 are loosened, the adjustment frame 34 can move left and right in the adjustment cavity 33, and at the same time, its other end passes through the slot 21 of the second connecting bracket 2 and moves in the slot 21, thereby changing the position of the adjustment frame 34, realizing the adjustment of the cutting angle, and also laying the foundation for subsequent adjustment of the cutter shaft gap.

[0028] The system includes a spacing adjustment mechanism 4, which includes a fastening sleeve 41. The fastening sleeve 41 is a U-shaped frame. A bolt passes through a fastening plate 42 at the bottom end of the fastening sleeve 41. The fastening sleeve 41 and the fastening plate 42 are fixed together by a nut sleeve 43. A connecting plate 44 is integrally formed on the outer side of the fastening plate 42. A sliding sleeve 45 is fixedly connected to the bottom end of the connecting plate 44. A cutter disc 46 is connected to the outer side of the sliding sleeve 45. A ball bearing is installed at the connection between the cutter disc 46 and the sliding sleeve 45. The sliding sleeve 45 is fitted onto the outer ring surface of the bearing 47.

[0029] The fastening sleeve 41 is fitted onto the outer ring surface of the adjusting frame 34 through the nut sleeve 43, and the fastening sleeve 41 moves to adjust its position on the outer ring surface of the adjusting frame 34.

[0030] More specifically, the fastening sleeve 41 of the gap adjustment mechanism 4 is a U-shaped frame, which is fitted onto the surface of the adjustment frame 34 via a nut sleeve 43. When it is necessary to adjust the cutter shaft clearance, the nut sleeve 43 is loosened, and the fastening sleeve 41 can move left and right on the adjustment frame 34, causing the fastening plate 42, connecting plate 44, and sliding sleeve 45 at its bottom end to move synchronously. The cutter disc 46 connected to the outside of the sliding sleeve 45 is connected to the sliding sleeve 45 via a ball bearing and can rotate around the sliding sleeve 45. The sliding sleeve 45 is fitted onto the surface of the bearing 47 to ensure the stability of the sliding sleeve 45 during movement. By adjusting the position of the fastening sleeve 41 on the adjustment frame 34, the clearance between the cutter discs 46 can be precisely changed.

[0031] A further technical solution involves adjusting the target gap, then tightening the nut sleeve 43 to fix the fastening sleeve 41 to the adjusting frame 34. Simultaneously, the fixing bolt 35 locks the position of the adjusting frame 34 within the adjusting cavity 33, and the locking bolt 32 secures the position of the adjusting mechanism 3 on the first connecting bracket 1. This multi-layered fixing structure effectively resists equipment vibration and the effects of prolonged operation, preventing deviation in the cutter shaft gap and ensuring the accuracy of the shearing operation and the stability of the equipment.

[0032] Working principle of the cutter shaft clearance adjustment device:

[0033] The principle of gap adjustment of the adjustment mechanism

[0034] The mounting bracket 31 in the adjustment mechanism 3 has adjustment cavities 33 on both sides, and the adjustment frame 34 is positioned with the mounting bracket 31 by fixing bolts 35. When the fixing bolts 35 are loosened, the adjustment frame 34 can move left and right in the adjustment cavity 33. At the same time, its other end passes through the slot 21 of the second connecting bracket 2 and moves in the slot 21, thereby changing the position of the adjustment frame 34, realizing the adjustment of the cutting angle, and laying the foundation for subsequent adjustment of the cutter shaft gap.

[0035] Precise adjustment principle of the spacing adjustment mechanism

[0036] The fastening sleeve 41 of the gap adjustment mechanism 4 is a U-shaped frame, which is fitted onto the surface of the adjustment frame 34 via a nut sleeve 43. When it is necessary to adjust the cutter shaft clearance, the nut sleeve 43 is loosened, and the fastening sleeve 41 can move left and right on the adjustment frame 34, causing the fastening plate 42, connecting plate 44, and sliding sleeve 45 at its bottom end to move synchronously. The cutter head 46 connected to the outside of the sliding sleeve 45 is connected to the sliding sleeve 45 via a ball bearing and can rotate around the sliding sleeve 45. The sliding sleeve 45 is fitted onto the surface of the bearing 47 to ensure the stability of the sliding sleeve 45 during movement. By adjusting the position of the fastening sleeve 41 on the adjustment frame 34, the clearance between the cutter heads 46 can be precisely changed.

[0037] Gap fixing and anti-displacement principle

[0038] After adjusting to the target gap, tighten the nut sleeve 43 to fix the fastening sleeve 41 to the adjusting frame 34. At the same time, lock the position of the adjusting frame 34 in the adjusting cavity 33 with the fixing bolt 35, and fix the position of the adjusting mechanism 3 on the first connecting bracket 1 with the locking bolt 32. The multi-layer fixing structure can effectively resist the effects of equipment vibration and long-term operation, prevent the blade shaft gap from shifting, and ensure the accuracy of the shearing operation and the stability of the equipment.
