Description

Technical Field

[0001] The utility model belongs to the technical field of grinders, and in particular relates to a grinder with a quick fixing structure. Background Art

[0002] PVC pipe grinder is a mechanical device specially used for grinding and polishing the surface of PVC (polyvinyl chloride) pipes. This machine is usually designed with contact parts and power drive systems suitable for the shape of PVC pipes. It can effectively remove burrs and uneven parts of PVC pipes after cutting, and improve their surface quality to ensure good sealing performance and beautiful appearance of the joints. PVC pipe grinders may be driven by electricity or pneumatics. By installing different types of grinding wheels, abrasive belts or polishing accessories, different degrees and degrees of grinding and fineness of PVC pipes can be achieved.

[0003] The PVC pipe fixing structure on some grinders was designed without fully considering the compressive strength and elastic properties of PVC pipes, resulting in excessive force applied during the clamping process, causing excessive extrusion and deformation of the pipe wall, and even causing the pipe to rupture. Although PVC pipes have a certain degree of flexibility, excessive clamping pressure will cause uneven stress distribution inside the pipe, which can easily cause microcracks in the PVC pipe and affect the service life of the pipe. Therefore, we hope to design a grinder with a new structure to solve this problem. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 4The utility model provides a technical solution: a grinder with a quick fixing structure, comprising: a grinder body 100, a screw module 200 and a fixing assembly 300, the screw module 200 is installed on the left side of the grinder body 100, and two fixing assemblies 300 for quick fixing of workpieces are movably installed on the upper side of the screw module 200;

[0028] The lead screw module 200 includes a base 210, a slide rail 220 and a slide seat 230. A slide rail 220 is fixed to the front and rear sides of the upper surface of the base 210, and a slide seat 230 is slidably mounted on the upper side of the base 210 through the slide rail 220.

[0029] The fixing assembly 300 includes a mounting plate 310, a limiting assembly 320, a supporting assembly 330 and a fixing block 340. The fixing block 340 is welded to the lower front side of the mounting plate 310 away from the slide seat 230, and the supporting assembly 330 is movably mounted on the upper front side of the mounting plate 310 away from the slide seat 230 through the fixing block 340.

[0030] A limiting assembly 320 is movably mounted on the upper rear side of the mounting plate 310 away from the slide seat 230 , and a cylinder 350 is mounted on the lower rear side of the mounting plate 310 away from the slide seat 230 .

[0031] See also Figures 1 to 3 The front side of the mounting plate 310 away from the slide seat 230 is recessed inward to form a guide groove 311, and a limiting rod 312 is provided on the upper rear side of the mounting plate 310 away from the slide seat 230. A yielding portion is provided on the front side of the upper end of the mounting plate 310. The setting of the guide groove 311 can limit the mounting seat 332.

[0032] The supporting assembly 330 includes a fixing rod 331, a mounting seat 332 and a second roller 333. The fixing rod 331 is welded to the lower end of the mounting seat 332. The lower end of the fixing rod 331 is fixedly connected to the fixing block 340 through a nut. A second roller 333 is symmetrically mounted on the front and rear sides of the upper end of the mounting seat 332.

[0033] The mounting seat 332 is slidably connected to the guide groove 311 at one side close to the mounting plate 310 .

[0034] The limiting assembly 320 includes a swing block 321 , a hinge column 323 and a pull rod 325 . The swing block 321 is hinged to the upper rear side of the mounting plate 310 away from the slide seat 230 through the hinge column 323 .

[0035] A roller 322 is rotatably installed at the front end of the swing block 321, and a waist hole 324 arranged in the front-to-back direction is opened on the rear side of the swing block 321. The rear end of the swing block 321 is slidably connected to the upper end of the pull rod 325 through the waist hole 324. By arranging roller 1 322 and roller 2 333, the PVC pipe is clamped by the rollable roller 1 322 and roller 2 333, which effectively prevents the fixing component 300 from damaging the PVC pipe due to excessive clamping force.

[0036] As the first embodiment of the utility model, in actual use, the user can adjust the installation height according to the diameter of the PVC pipe to be fixed. Specifically, the user loosens the nut connecting the lower side of the fixing rod 331 and the fixing block 340, adjusts the height of the fixing rod 331, and then can adjust the height of the mounting seat 332. The adjustment of the height of the mounting seat 332 means that the spacing between it and the lower side of the roller one 322 is adjusted, so that PVC pipes of different diameters can be used. The two symmetrically installed rollers 333 on the upper side of the mounting seat 332 can support the front lower side and the rear lower side of the PVC pipe placed thereon. The two rolling rollers 333 can adaptively follow the rotation when the PVC pipe is subjected to a rotational force in the circumferential direction, thereby ensuring that the PVC pipe is in a state of force balance when fixed, and avoiding damage when fixed.

[0037] See also Figure 3 to Figure 4 The middle of the pull rod 325 passes through the mounting plate 310 to form a second waist hole 326, and the pull rod 325 is slidably connected to the limit rod 312 through the second waist hole 326, and the lower end of the pull rod 325 is fixedly connected to the upper end of the piston rod of the cylinder 350.

[0038] The first roller 322 is located right above the middle of the two second rollers 333 . The edges of the first roller 322 and the second roller 333 are both covered with rubber anti-slip sleeves. The diameter of the first roller 322 is less than or equal to the diameter of the second roller 333 .

[0039] As the second embodiment of the utility model, in actual use, after the PVC pipe is placed, the cylinder 350 is started to push the pull rod 325 upward. The pull rod 325 moves upward under the action of the limit rod 312 and the waist hole 326, and pushes the rear end of the swing block 321 to move upward. Under the action of the waist hole 326 and the hinge column 323, the swing block 321 rotates counterclockwise with the hinge column 323 as the center, thereby driving the roller 1 322 thereon to press the upper end of the PVC pipe on the supporting assembly 330. At this point, the two rollers 2 333 and the one roller 1 322 support the three points on the PVC pipe that are equilateral triangles or isosceles triangles, which effectively prevents the problem of excessive clamping force while ensuring fast and stable clamping.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
