[0024] like Figure 1 to Figure 3 As shown, a small center support frame for a broach blade grinder comprises a support base plate 1, a bolt hole 6 is provided in the middle of the support base plate 1, and the bolt hole 6 is installed on the grinder workbench by connecting a fastening component; a support vertical plate 2 is provided on the support base plate 1, and the support vertical plate 2 is provided with a slope support seat 3 on both sides of the length direction, and a multi-stage adjustable diagonal support assembly 4 is provided in the slope support seat 3, and a support end 5 is provided at the upper end of the diagonal support assembly 4.

[0025] The small center support frame for the broach blade grinder has a simple and compact structure, occupies a small space, is easy to install and use, can be installed on a small grinder workbench to support the workpiece to be processed, and has a multi-level adjustment function to adapt to the support of workpieces of various sizes and models.

[0026] The support base plate 1 can be conveniently fixed on the grinder workbench by using the bolt holes 6 and the fastening assembly. The pair of slope support seats 3 arranged on the support vertical plate 2 can be used to obliquely install the diagonal support assembly 4. The diagonal support assembly 4 can directly support the workpiece by using the supporting end 5 at its end, especially for the broaching workpiece with a slender structure, auxiliary support can be provided from the middle so that the grinder can process its blade.

[0027] The diagonal support assembly 4 can be adjusted in multiple stages to change the distance between a pair of supporting ends 5 so as to support broach workpieces of various sizes and types.

[0028] Furthermore, the supporting end 5 may be an end with a roller, or a conical end with a tooth groove.

[0029] Furthermore, the support base plate 1 is a rectangular plate, the bolt hole 6 is one and is arranged in the middle of the support base plate 1; the fastening assembly includes a fastening bolt 7 invertedly connected to the bolt hole 6, and a washer and a nut connected to the fastening bolt 7. Through this arrangement, the steps of connecting the support base plate 1 with the grinding machine workbench can be simplified, and only one bolt is needed to fix the support frame, which fully utilizes the existing structure on the grinding machine workbench to complete the installation.

[0030] like Figure 4The figure shows the overall structure of a broach blade grinder. A grinder worktable 9 is provided within the processing range of the grinder. A self-centering fixture and a tailstock are provided at both ends of the grinder worktable 9, respectively. The space between the two is used to clamp the workpiece. A T-slot 10 is provided in the middle of the grinder worktable 9 along the length direction. The fastening bolt 7 can be provided in the T-slot 10. The bolt hole 6 on the support base plate 1 is sleeved on the fastening bolt 7. After adjusting the position, the gasket and the nut can be used for fastening. For broach processing, the size of the worktable is not very large. If the size of the center support frame is too large, it will cause inconvenience in its installation. The length, width and height of the center support frame can be well controlled and will not be too large, which is suitable for the use of this type of broach blade grinder.

[0031] Furthermore, the support vertical plate 2 is an n-shaped plate, the thickness of the support vertical plate 2 is smaller than the width of the support bottom plate 1, the support vertical plate 2 is arranged along the center line of the support bottom plate 1, and the slope support seats 3 are respectively arranged at the upper two corners of the support vertical plate 2.

[0032] Through the above arrangement, the supporting upright plate 2 can be vertically arranged in the middle of the supporting base plate 1 without exceeding the length and width of the supporting base plate 1. The middle part of the supporting upright plate 2 is a hollow structure, which can bear its overall weight on the one hand, and on the other hand, free up space in the middle to facilitate the connection, installation and disassembly of the fastening components.

[0033] The supporting upright plate 2 and the supporting bottom plate 1 are integrally formed metal structural members, or are welded together.

[0034] Furthermore, the slope support seat 3 includes a cylindrical seat body 301, the central axis of the seat body 301 is arranged at an angle, and the diagonal support assembly 4 is sleeved in the seat body 301; a slit 302 is provided on the outer side of the seat body 301 along the length direction, and connecting ear plates 303 are provided on both sides close to the slit 302, and the connecting ear plates 303 are connected by bolts.

[0035] The seat body 301 uses the slit 302 provided on its outer wall to allow it to have a certain clamping and loosening ability, and with the arrangement of a pair of connecting ear plates 303 and bolts, the diagonal brace assembly 4 can be slidably adjusted in the seat body 301, and can also clamp and fix the diagonal brace assembly 4. The slit 302 can be an overall slit that runs through the length direction of the outer wall, or it can be a partial slit.

[0036] Furthermore, the diagonal support assembly 4 includes a sleeve 401 sleeved in the slope support seat 3, the axial length of the sleeve 401 is greater than the axial length of the slope support seat 3, a support rod 402 is slidably provided in the sleeve 401, one end of the support rod 402 extends out of the sleeve 401 and is connected to the support end 5, the other end of the support rod 402 is provided with an internal threaded hole along the axial direction and is connected to an adjusting screw 403, the other end of the adjusting screw 403 extends out of the sleeve 401 and is connected to an adjusting knob 404.

[0037] Since the length of the sleeve 401 is greater than the length of the seat body 301, the sleeve 401 can be adjusted in the circumferential direction relative to the seat body 301 in a primary manner, and the adjustment range is relatively large; by turning the adjusting knob 404 to drive the adjusting screw 403 to rotate, the axial length adjustment of the support rod 402 is a secondary adjustment, which is more precise and has a higher accuracy.

[0038] Some scale marks may also be provided along the length direction of the outer circumference of the sleeve 401 , the support rod 402 and the seat body 301 , so that the operator can know the adjustment distance in real time during adjustment.

[0039] Furthermore, a limiting groove 405 is provided on the outer periphery of the support rod 402 along the length direction, and a limiting screw 406 is provided on the sleeve 401. One end of the limiting screw 406 is located in the limiting groove 405, and the other end of the limiting screw 406 does not exceed the outer peripheral surface of the sleeve 401 to avoid protruding and affecting the position adjustment of the sleeve 401.

[0040] The setting of the limiting groove 405 and the limiting screw 406 can, on the one hand, limit the circumferential position of the support rod 402 to prevent the support rod 402 from relative rotation, and on the other hand, can also limit the axial position of the support rod 402 to limit the adjustment stroke in the axial length direction.

[0041] Furthermore, the angle between the central axes of the pair of diagonal brace assemblies 4 is 90 degrees, that is, the central axes of the two diagonal brace assemblies are arranged at an angle of 45 degrees; the maximum diameter of the circumscribed circle of the end of the pair of supporting end heads 5 does not exceed 100 mm, and the maximum radial dimension (side length) of the outer circumference of the workpiece that can be supported does not exceed 100 mm.

[0042] Furthermore, a pad 8 is provided below the support base plate 1 , which is beneficial for stably locking the support base plate 1 on the grinder workbench 9 .

[0043] Furthermore, the aspect ratio of the support base plate 1 is not less than 2:1. In this embodiment, the width of the support base plate is about 60 mm, the length is about 120 mm, and the overall height is about 210 mm.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
