Abstract
Description
Technical Field
[0001] The utility model relates to the field of grinding equipment, in particular to a fixing mechanism for pipe shaft grinding equipment. Background Art
[0002] The pipe shaft is a component of a tubular structure. As a tubular connecting piece, the pipe shaft requires a smooth surface and ends, and the ends of the pipe shaft need to be chamfered and deburred according to specific needs to facilitate the connection of two adjacent pipe shafts. In different applications, due to the different required pipe shaft lengths, the pipe shaft raw materials will be cut into pipe shaft semi-finished products of a certain length during the production process, resulting in pipe shafts of different sizes being difficult to fix through the same fixing mechanism, which in turn leads to unstable fixation when the ends of the pipe shaft are polished.
[0003] At the same time, in order to prevent the end of the tube shaft from slipping or circumferential rotation during the grinding process, a larger clamping force is currently required for fixing the tube shaft. However, a larger clamping force will cause dents to appear on the outer wall of some tube shafts, reducing the yield rate of the tube shaft. Utility Model Content
[0004] The utility model aims to provide a fixing mechanism for a pipe shaft grinding device which improves the convenience of fixing a pipe shaft workpiece during grinding and prevents the outer side of the pipe shaft workpiece from being damaged due to excessive clamping force.
[0005] In order to solve the above-mentioned technical problems, the utility model provides a fixing mechanism for a pipe shaft grinding equipment, comprising a processing table, a supporting assembly arranged on the processing table, and a fixing assembly arranged on one side of the processing table, wherein the fixing assembly comprises a support seat and a plurality of support rods rotatably arranged on the support seat, and the support assembly comprises a positioning rod arranged for lifting and lowering and a supporting wheel arranged on the positioning rod, so that when the pipe shaft is placed on the supporting wheel, the plurality of support rods support the inner side of one end of the pipe shaft.
[0006] Furthermore, an adjusting rod is telescopically arranged on one side of the support seat, and a plurality of support rods are distributed at intervals along the circumference of the adjusting rod, and a connecting rod is connected between the side of the adjusting rod and the support rod, and the two ends of the connecting rod are respectively rotationally cooperated with the adjusting rod and the support rod, so that when the adjusting rod is contracted, the plurality of support rods synchronously support the inner side of the tube axis.
[0007] Furthermore, a limiting ring is sleeved on the outer periphery of the adjusting rod, the limiting ring can move relative to the axial direction of the adjusting rod, and the edge of the limiting ring is located on the inner side of the connection between the support rod and the connecting rod.
[0008] Furthermore, a sliding groove is provided on the outer wall of the adjusting rod along the axial direction, a sliding block is provided on the inner side of the limiting ring, and the sliding block is in sliding fit with the sliding groove.
[0009] Furthermore, a positioning piece is detachably connected to the inner side of the slide groove so that the positioning piece limits the movement stroke of the slider.
[0010] Furthermore, one end of the support rod away from the support seat is in an arc-shaped structure.
[0011] Furthermore, both ends of the positioning rod are provided with moving blocks, which are movably arranged in the moving track so that the moving block can move in the height direction along the moving track, and an elastic member is connected between the side of the moving block and the processing table.
[0012] Furthermore, a tightening piece is threadedly connected to the top of the moving track, and an end of the tightening piece passes through the moving track and abuts against one side of the moving block, so that when the tightening piece rotates relative to the moving track, the moving block moves relative to the moving track.
[0013] Furthermore, a V-shaped supporting groove is formed on the supporting wheel along the circumference.
[0014] Furthermore, scale lines are arranged on the outer side of the tightening member along the height direction.
[0015] The beneficial effect of the utility model is that when grinding the end of a pipe shaft workpiece, the pipe shaft is placed on the supporting wheel so that the supporting wheel supports the pipe shaft, and then one end of the pipe shaft is moved close to the support seat so that a plurality of support rods enter the inner side of the pipe shaft from the end of the pipe shaft. At this time, a plurality of support rods are simultaneously expanded and stretched out outward so that a plurality of support rods are supported from the inner side of the pipe shaft, and then the pipe shaft is simultaneously supported and limited by the support of the supporting wheel so as to ensure the fixation and stability of the pipe shaft, and since a plurality of support rods are located on the inner side of the pipe shaft, no convex points are generated on the outer wall of the pipe shaft.
[0016] At the same time, since the positioning rod is liftable, the height of the supporting wheel can be adjusted. When pipe shafts of different sizes are placed on the supporting wheel, the axial position of the current pipe shaft can be adjusted by lifting the positioning rod, thereby ensuring that the axial position of the pipe shaft coincides with the supporting positions of several support rods to ensure the supporting effect.

Detailed implementation manners
[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention shall fall within the protection scope of the present invention.
[0022] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.
[0023] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of the element can be multiple. The term "one" should not be construed as limiting the quantity.
[0024] As Figures 1-3 described, the present invention provides a fixing mechanism for a pipe shaft grinding device, including a processing table 1, a material supporting assembly arranged on the processing table 1, and a fixing assembly arranged on one side of the processing table 1. The fixing assembly includes a support base 2 and a plurality of support rods 3 rotatably arranged on the support base 2. The material supporting assembly includes a lifting positioning rod 4 and a material supporting wheel 5 arranged on the positioning rod 4. When the pipe shaft is placed on the material supporting wheel 5, a plurality of support rods 3 support the inner side of one end of the pipe shaft.
[0025] When grinding the end of a pipe shaft workpiece, place the pipe shaft on the material supporting wheel so that the material supporting wheel supports the pipe shaft. Then, move one end of the pipe shaft close to the support base, so that several support rods enter the inner side of the pipe shaft from the end of the pipe shaft. At this time, several support rods expand outwards synchronously, so that several support rods support from the inner side of the pipe shaft. Furthermore, the pipe shaft is simultaneously supported and limited by several support rods and supported by the material supporting wheel to ensure the stable fixation of the pipe shaft. And since several support rods are inside the pipe shaft, no bumps will be generated on the outer wall of the pipe shaft.
[0026] At the same time, since the positioning rod is arranged to be liftable, the height of the material supporting wheel can be adjusted. When pipe shafts of different sizes and specifications are placed on the material supporting wheel, the axis position of the current pipe shaft can be adjusted by lifting the positioning rod, so as to ensure that the axis position of the pipe shaft coincides with the supporting position of several support rods to ensure the supporting effect.
[0027] It is worth mentioning that when several support rods internally support one end of the pipe shaft, the grinding device grinds the other end of the pipe shaft to ensure the stable grinding of the end of the pipe shaft. Then, the ground end can be fixed by the support rods to facilitate the grinding process of the other unground end.
[0028] In an embodiment of this solution, the end of the support rod 3 away from the support base 2 is in an arc structure 13, so that when the support rod rotates relative to the support base, the arc structure can adapt to the inner walls of more pipe shafts of different sizes and specifications and ensure the supporting effect of the support rod on the pipe shaft.
[0029] Preferably, an adjusting rod 7 is telescopically arranged on one side of the support base 2. Several support rods 3 are circumferentially spaced along the adjusting rod 7, and a connecting rod 8 is connected between the side of the adjusting rod 7 and the support rod 3. Both ends of the connecting rod 8 are rotatably matched with the adjusting rod 7 and the support rod 3 respectively, so that when the adjusting rod 7 contracts, several support rods 3 simultaneously support the inner side of the pipe shaft.
[0030] Specifically, when controlling the rotation of the support rod, by telescopically controlling the adjusting rod, when the adjusting rod contracts, it drives the connecting rod to push the support rod, so that the support rod rotates to a position away from the adjusting rod, and then the support rod abuts against the inner wall of the pipe shaft. Similarly, by extending the adjusting rod, it drives the connecting rod to pull the support rod, so that the support rod releases the restraint on the pipe shaft, which is convenient for unloading the pipe shaft.
[0031] In an embodiment of this solution, the adjusting rod is controlled to expand and contract by a cylinder or a hydraulic cylinder.
[0032] Preferably, a limit ring 9 is sleeved on the outer periphery of the adjusting rod 7. The limit ring 9 can move axially relative to the adjusting rod 7, and the edge of the limit ring 9 is located inside the connection between the support rod 3 and the connecting rod 8.
[0033] Specifically, when the adjusting rod controls the rotation of several struts relative to the support base through telescoping, the inner side of the connection between the strut and the connecting rod is limited by the limiting ring, avoiding the situation that the elongation stroke of the adjusting rod is too large, resulting in the connecting rod over-pulling the strut, and further avoiding the situation that the connection between the strut and the connecting rod folds inward, causing the strut to be unable to normally support the inner wall of the pipe shaft.
[0034] Preferably, a chute 10 is axially formed on the outer wall of the adjusting rod 7, the inner side of the limiting ring 9 has a slider 11, and the slider 11 is in sliding fit with the chute 10.
[0035] Specifically, when the connecting rod drives the strut to rotate by moving the slider relative to the chute, the limiting ring can be pushed by the inner side of the connecting rod or the inner side of the strut, so that the limiting ring can move axially relative to the adjusting rod to ensure that the limiting ring is stably located inside the connection between the strut and the connecting rod.
[0036] Preferably, a positioning member 12 is detachably connected inside the chute 10 to limit the moving stroke of the slider 11.
[0037] Specifically, the moving stroke of one side of the slider is limited by the positioning member, and the other side of the slider is limited by the end of the chute to ensure that the slider is stably movably arranged in the chute. And due to the detachable setting of the positioning member, after the positioning member is disassembled, the limiting ring can be taken out from the adjusting rod to ensure the repair and replacement of parts.
[0038] Among them, the positioning member can adopt components such as bolts and screws.
[0039] Preferably, both ends of the positioning rod 4 have moving blocks 14, and the moving blocks 14 are movably arranged in the moving tracks 15, so that the moving blocks 14 can move in the height direction along the moving tracks 15, and an elastic member 16 is connected between the side of the moving blocks 14 and the processing table 1.
[0040] Specifically, the elastic member holds the moving block at a certain height of the moving track, so that when the pipe shaft is supported on the material supporting wheel, the weight of the pipe shaft can be supported by the elastic member, avoiding the situation that the pipe shaft directly presses down the moving block.
[0041] Among them, the elastic member adopts an industrial spring, and this industrial spring needs to have the ability to support the weight of the pipe shaft.
[0042] Preferably, a tightening member 17 is threadedly connected to the top of the moving track 15, and the end of the tightening member 17 passes through the moving track 15 and abuts against one side of the moving block 14, so that when the tightening member 17 rotates relative to the moving track 15, the moving block 14 moves relative to the moving track 15.
[0043] Specifically, when adjusting the height of the material supporting wheel, by rotating the fastening member, the fastening member pushes the moving block downward, compressing the elastic member at the same time, so that both sides of the moving block are limited by the fastening member and the elastic member respectively, thereby ensuring the stability of the moving block. At this time, the height of the material supporting wheel can be controlled by rotating the fastening member to different heights to adapt to pipe shafts with different outer diameters.
[0044] Among them, the fastening member can adopt a bolt structure.
[0045] In an embodiment of the present solution, scale lines are arranged along the height direction on the outer side of the fastening member 17, so that when the fastening member adjusts the height of the moving block, the height adjustment position of the material supporting wheel can be clearly and intuitively known by observing the scale lines.
[0046] Preferably, the material supporting wheel 5 is provided with a material supporting groove 18 having a V-shaped structure along the circumferential direction, so that when the pipe shaft is supported on the material supporting wheel, the side of the pipe shaft can be positioned through the material supporting groove, improving the placement stability of the pipe shaft.
[0047] The present utility model is not limited to the above best embodiment. Any person can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has the same or similar technical solutions as the present application, it falls within the protection scope of the present utility model.
