Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a protective device for machining equipment. Background Technology

[0002] In existing technologies, protective devices for machining equipment require the application of elastic force to the protective plate during use to prevent damage to the interior. Existing equipment uses springs to apply elastic force, and the elastic force is adjusted by increasing or decreasing the number of springs, resulting in low work efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a protective device for machining equipment, which solves the problem that existing equipment adjusts elastic force by increasing or decreasing the number of springs, resulting in low work efficiency.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0005] A protective device for machining equipment is characterized by comprising an adjusting rod, a radially through hole on the adjusting rod, an insertion rod disposed within the through hole, one end of the insertion rod being connected to a fixed sleeve via a damping assembly, the fixed sleeve being mounted on a support frame, a segmented adjusting spring assembly being fitted onto the insertion rod, and a protective plate being horizontally mounted on the adjusting rod via the fixed rod.

[0006] The segmented adjusting spring assembly includes an adjusting spring, a transverse rod, and an adjusting disc. The adjusting spring is mounted on the insertion rod, and its bottom is connected to a fixing groove on the adjusting rod via a fixing block. A limiting disc is provided at the front end of the adjusting spring and is mounted on the insertion rod. An adjusting disc is provided along the length of the adjusting spring, and the adjusting disc has a through hole through which the adjusting spring passes. At least two transverse rods are provided on the adjusting disc, and the transverse rods are detachably connected to the adjusting disc. Adjacent adjusting discs have receiving sleeves that fit onto the transverse rods. Both ends of the transverse rods are fixedly mounted on the adjusting discs with nuts. The adjusting discs have grooves for engaging with the transverse rods.

[0007] The damping assembly includes a damping disc and rubber balls. A fixed sleeve is slidably connected to the support frame. The damping disc is installed on the fixed sleeve, and multiple rubber balls are provided inside the damping disc.

[0008] It also includes a bonding disc and a threaded disc. One end of the bonding disc has a middle block with an insertion groove. The threaded disc has a middle groove. The bonding disc and the threaded disc are installed on the insertion rod. The middle block is engaged in the middle groove of the threaded disc. The insertion groove and the middle groove are installed together. A limiting disc is installed on the insertion rod outside the bonding disc. Multiple anti-slip grooves are provided on the side of the limiting disc.

[0009] The beneficial effects of this utility model are:

[0010] (1) This utility model solves the problem of low efficiency in disassembling springs by inserting a segmented adjusting spring assembly onto the rod and adding a receiving sleeve to the segmented adjusting spring assembly to change the elastic force by changing the deformable length of the adjusting spring.

[0011] (2) The adjusting spring of this utility model is fixed on the insertion rod by the fixing block and the limiting plate, which ensures the stability of the fixing of the adjusting spring and the insertion rod. The adjusting spring passes through the through hole of the adjusting plate, and the adjusting plate divides the adjusting spring into several deformation zones evenly. The deformation zones are controlled by the receiving sleeve sleeved on the horizontal rod.

[0012] (3) When the protective plate of this utility model rebounds from an external impact, the damping disc absorbs part of the impact force, avoiding the adjustment spring from directly receiving the impact force and causing mechanical fatigue, which leads to a reduction in the stiffness coefficient.

[0013] (4) The adjusting rod of this utility model is provided with a protective plate, and a fixing rod is threaded on the adjusting rod. The fixing rod is attached to the protective plate, which increases the safety factor.

[0014] (5) The threaded disc of this utility model is provided on the adjusting spring. A middle groove is provided on the threaded disc. The middle block is engaged in the middle groove. A limiting disc is threaded on the threaded disc. The limiting disc abuts against the fitting disc. Multiple anti-slip grooves are provided on the side of the limiting disc. The limiting disc can apply a clamping force to adjust the overall rebound effect of the adjusting spring.

[0015] (6) The transverse rod of this utility model is provided with a receiving sleeve, and the two ends of the receiving sleeve abut against the two sides of the adjustment plate respectively. The two ends of the transverse rod are provided with hexagonal blocks respectively. The transverse rod is threaded with a nut, which fits against the adjustment plate. The two ends of the transverse rod are fixed by the nut. The adjustment spring at the fixed position cannot be deformed. Therefore, only the adjustment spring at the unconnected position can generate elastic force. Since the length of the adjustment spring is changed, the elastic force provided is also different, thus completing the adjustment of the elastic force. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

The transverse rods 19 are detachably connected to the adjusting disc 20. Adjacent adjusting discs 20 are provided with receiving sleeves 22, which are fitted onto the transverse rods 19. The two ends of the transverse rods 19 are fixedly mounted on the adjusting disc 20 by nuts 24. The adjusting disc 20 has a groove 21 for engaging with the transverse rods 19.

[0026] like Figure 1 , Figure 3As shown, the damping assembly includes a damping disc 3 and rubber balls 4. The fixing sleeve 2 is slidably connected to the support frame 1, the damping disc 3 is installed on the fixing sleeve 2, and multiple rubber balls 4 are provided inside the damping disc 3.

[0027] like Figure 3 As shown, it also includes a bonding disc 13 and a threaded disc 15. One end of the bonding disc 13 is provided with a middle block 12, and an insertion groove 14 is provided on the middle block 12. The threaded disc 15 is provided with a middle groove 16. The bonding disc 13 and the threaded disc 15 are installed on the insertion rod 5. The middle block 12 is snapped into the middle groove 16 of the threaded disc 15. The insertion groove 14 and the middle groove 16 are installed in cooperation with each other. The limiting disc 17 is installed on the insertion rod 5 on the outside of the bonding disc 13. Multiple anti-slip grooves 18 are provided on the side of the limiting disc 17.

[0028] In use, the support frame 1 is installed on an external device, and the support frame 1 and the fixed sleeve 2 are slidably sleeved together. The adjusting rod 6 is connected to the protective plate 10 through the fixed rod 11. The damping disc 3 is installed between the fixed sleeve 2 and the adjusting rod 6. The adjusting rod 6 is rotatably connected to the insertion rod 5. One end of the segmented adjusting spring assembly is fixedly connected to the insertion rod 5, and the other end is fixedly connected to the fixing groove 9 of the adjusting rod 6. The adjusting spring 8 of the segmented adjusting spring assembly is installed on the insertion rod 5, and its bottom is fixedly connected to the fixing groove 9 on the adjusting rod 6 through the fixing block 7. The front of the adjusting spring 8... A limiting plate 17 is provided at one end. A fitting plate 13 and a threaded plate 15 are provided between the adjusting spring 8 and the limiting plate 17. A middle block 12 is provided at one end of the fitting plate 13. An insertion groove 14 is provided on the middle block 12. A middle groove 16 is provided on the threaded plate 15. The fitting plate 13 and the threaded plate 15 are installed on the insertion rod 5. The middle block 12 is engaged in the middle groove 16 of the threaded plate 15. The insertion groove 14 and the middle groove 16 are installed in cooperation with each other. Multiple anti-slip grooves 18 are provided on the side of the limiting plate 17. The multiple anti-slip grooves 18 are equally spaced to facilitate the adjustment of the limiting plate 17.

[0029] The adjusting spring 8 has several adjusting discs 20 along its length, which evenly distribute the adjusting spring 8. Each adjusting disc 20 has a through hole through which the adjusting spring 8 passes. Each adjusting disc 20 has at least two horizontal rods 19, which are detachably connected to the adjusting disc 20. Each adjacent adjusting disc 20 has a receiving sleeve 22, which is fitted onto the horizontal rod 19. Both ends of the horizontal rod 19 are fixedly installed on the adjusting disc 20 by nuts 24. Each adjusting disc 20 has a groove 21 for engaging with the horizontal rod 19. The horizontal rod 19 is hexagonal 23, which increases the engagement surface between the horizontal rod 19 and the groove 21 to prevent slippage during use and thus maintain the adjustment effect.

[0030] In use, the overall rebound effect of the adjusting spring 8 is set by twisting the limiting plate 17. At this time, the transverse rod 19 is not installed to lock the deformation area. When adjusting the rebound strength, the transverse rod 19 is engaged in the groove 21 of the adjusting plate 20 of the adjusting spring 8 in the area where the deformation is not desired. The receiving sleeve 22 is sleeved on the transverse rod 19 between two adjacent adjusting plates 20 in the locking area. The nuts 24 at both ends of the transverse rod 19 are tightened. The receiving sleeve 22 prevents the adjusting spring 8 from deforming along the length direction in the locking area by tightening the nuts 24. By changing the engagement length between the transverse rod 19 and the adjusting plate 20, the adjusting spring 8 in the locked position cannot deform. Therefore, only the adjusting spring 8 in the position not connected to the transverse rod 19 generates elasticity. Since the length of the adjusting spring 8 is changed, the elasticity provided is also different, thus completing the adjustment of different rebound strengths.
