Description

Technical Field

[0001] This utility model relates to the field of auxiliary support technology, specifically to a novel large-stroke self-locking auxiliary support mechanism. Background Technology

[0002] Auxiliary supports are added to improve the clamping rigidity and stability of workpieces, as these supports may cause deformation or instability in the workpiece after positioning due to factors such as workpiece shape, clamping force, cutting force, and workpiece weight. Auxiliary supports only serve to improve the rigidity of the workpiece and do not restrict its degrees of freedom, nor do they disrupt its original positioning.

[0003] Most existing auxiliary supports are standard parts with fixed strokes, which cannot adequately meet on-site requirements. Therefore, we propose a novel large-stroke self-locking auxiliary support mechanism. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems in the prior art and provide a new type of large-stroke self-locking auxiliary support mechanism that ensures sufficient stroke during use and locks the stroke, thereby well meeting the needs of the field.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A novel large-stroke self-locking auxiliary support mechanism includes an auxiliary support base, on which a large-stroke auxiliary support component is provided, and on the side of the auxiliary support base is a self-locking component that cooperates with the large-stroke auxiliary support component.

[0007] The large-stroke auxiliary support includes a stroke cylinder and a support rod. The stroke cylinder is mounted on the bottom of the auxiliary support base via a cylinder mounting plate. The lower end of the support rod is movably disposed in the auxiliary support base, and a support head is mounted on the top of the support rod. Two spring pads are symmetrically arranged inside the support rod, and a spring is disposed between the two spring pads. The top of one spring pad abuts against the support head. The power extension end of the stroke cylinder extends movably into the support rod and connects to the other spring pad.

[0008] Preferably, the self-locking component includes a positioning seat, which is installed on one side of the auxiliary support seat. A locking rod that cooperates with the support rod is movably disposed inside the positioning seat. A locking cylinder is installed on the side of the positioning seat away from the auxiliary support seat. The power extension end of the locking cylinder is connected to the locking rod through a connecting joint.

[0009] Based on the above technical features, it is convenient for the locking cylinder to drive the locking rod to move when it is working.

[0010] Preferably, the positioning seat has a protrusion on one side close to the auxiliary support seat, and the auxiliary support seat has an insertion hole on one side that mates with the protrusion; the insertion hole has a moving hole that mates with the locking rod, and the moving hole is connected to the interior of the auxiliary support seat.

[0011] Based on the above technical features, it is easy to move the locking rod to perform the locking operation.

[0012] Preferably, a locking head is provided at the end of the locking rod away from the connecting joint, and a locking groove that mates with the locking head is provided on one side of the outer wall of the support rod.

[0013] Based on the above technical features, after the support rod moves, the locking head is inserted into the locking groove to lock and fix the moved support rod, thus completing the self-locking action.

[0014] Preferably, the outer wall of the locking rod is provided with a first guide groove, and the outer wall of the positioning seat is provided with a first screw through hole.

[0015] Based on the above technical features, by using a positioning screw screwed into the first screw through hole and extending its cylindrical end into the first guide groove, the locking rod in the positioning seat only moves in its length direction and does not rotate.

[0016] Preferably, a second guide groove is provided on the other side of the outer wall of the support rod, and a second screw through hole is provided on the other side of the outer wall of the auxiliary support seat.

[0017] Based on the above technical features, by using another positioning screw to be screwed into the second screw through hole and extending its cylindrical end into the second guide groove, the support rod can only move in its length direction in the auxiliary support seat without rotating.

[0018] Preferably, the top of the auxiliary support base is provided with a sealing groove, and a dustproof sealing ring is installed in the sealing groove.

[0019] Based on the above technical features, it is easy to achieve a dustproof and sealing function.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] This utility model installs a large-stroke auxiliary support on an auxiliary support base. Powered by a stroke cylinder, the support rod moves on the auxiliary support base through the cooperation of a spring and a support head, allowing the support head to eventually contact and press against the workpiece. A self-locking component is used in conjunction with the large-stroke auxiliary support to ensure sufficient stroke during use and to lock the stroke, thus well meeting the practical needs of the field.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-18 The present invention will be described in further detail below.

[0043] One embodiment of this utility model is shown below: Figure 1 A novel large-stroke self-locking auxiliary support mechanism includes an auxiliary support base 1, a large-stroke auxiliary support component 2 on the auxiliary support base 1, and a self-locking component 3 that cooperates with the large-stroke auxiliary support component 2 on the side of the auxiliary support base 1.

[0044] See Figure 2 , Figure 8 , Figure 11 , Figure 12 , Figure 13 The large-stroke auxiliary support component 2 includes a stroke cylinder 201 and a support rod 204. The stroke cylinder 201 is installed at the bottom of the auxiliary support base 1 via a cylinder mounting plate 202. The lower end of the support rod 204 is movably disposed in the auxiliary support base 1. A support head 206 is installed on the top of the support rod 204. Two spring pads 203 are symmetrically arranged inside the support rod 204. A spring 205 is arranged between the two spring pads 203. The top of one spring pad 203 abuts against the support head 206. The power extension end of the stroke cylinder 201 extends movably into the interior of the support rod 204 and connects with the other spring pad 203. A sealing groove is opened on the top of the auxiliary support base 1. A dustproof sealing ring 4 is installed in the sealing groove, which facilitates dustproof sealing when the support rod 204 is working.

[0045] See Figure 2 , Figure 3The self-locking component 3 includes a positioning seat 303, which is installed on one side of the auxiliary support seat 1. The positioning seat 303 has a locking rod 304 that cooperates with the support rod 204. A locking cylinder 301 is installed on the side of the positioning seat 303 away from the auxiliary support seat 1. The power extension end of the locking cylinder 301 is connected to the locking rod 304 through a connecting joint 302, so that the locking cylinder 301 can drive the locking rod 304 to move when it is working.

[0046] See Figure 2 , Figure 4 , Figure 5 , Figure 14 The positioning seat 303 has a protrusion on one side close to the auxiliary support seat 1. The auxiliary support seat 1 has a hole 103 on one side that matches the protrusion. The protrusion is inserted into the hole 103 to facilitate the initial installation and positioning of the positioning seat 303 and the auxiliary support seat 1. The hole 103 has a moving hole 102 that matches the locking rod 304. The moving hole 102 is connected to the interior of the auxiliary support seat 1 to facilitate the movement of the locking rod 304 for locking.

[0047] See Figure 2 , Figure 6 , Figure 7 , Figure 9 , Figure 10 The locking rod 304 has a locking head at one end away from the connecting joint 302. The outer wall of the support rod 204 has a locking groove 7 that mates with the locking head. After the support rod 204 moves, the locking head is inserted into the locking groove 7 to lock and fix the moved support rod 204, thus completing the self-locking action.

[0048] See Figure 2 , Figure 4 , Figure 6 The locking rod 304 has a first guide groove 5 on its outer wall and the positioning seat 303 has a first screw through hole on its outer wall. By using a positioning screw to screw into the first screw through hole and extending its cylindrical end into the first guide groove 5, the locking rod 304 can only move in its length direction in the positioning seat 303 and does not rotate.

[0049] See Figure 2 , Figure 4 , Figure 9 , Figure 10 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18A second guide groove 6 is provided on the other side of the outer wall of the support rod 204, and a second screw through hole is provided on the other side of the outer wall of the auxiliary support seat 1. By using another positioning screw to screw into the second screw through hole and extending its cylindrical end into the second guide groove 6, the support rod 204 can only move in its length direction in the auxiliary support seat 1 without rotating.

[0050] Working principle:

[0051] The stroke cylinder 201 operates to push a set of spring pads 203 to compress spring 205. Spring 205 is compressed and contracts, and the rebound force acts between the two spring pads 203, causing another set of spring pads 203 to compress the support head 206 and generate thrust. This ultimately drives the support rod 204 to move in the auxiliary support seat 1, allowing the support head 206 to finally contact and compress the workpiece. Then, the locking cylinder 301 operates to push the locking rod 304 to move in the positioning seat 303, causing the locking rod 304 to compress the moved support rod 204 to achieve a limit, thereby ensuring sufficient stroke during use and locking the stroke, which can well meet the practical needs on site.

[0052] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
