Description

Technical Field

[0001] This utility model relates to the field of vertical grinding machine technology, specifically to a directional clamping mechanism for feeding materials in a vertical grinding machine. Background Technology

[0002] A vertical surface grinder is a high-precision machine used for machining three-dimensional planes. To ensure the machining effect, it is necessary to use an efficient clamping mechanism to firmly hold the workpiece and avoid deviation or shaking during the feeding process, which would affect the grinding accuracy.

[0003] Common grinding machine feeding mechanisms often employ single-sided clamping or two-point symmetrical clamping, failing to achieve uniform clamping in four directions. This leads to problems such as workpiece skewing or insecure clamping during the clamping process. Especially during high-speed vertical feeding, this uneven clamping can easily cause workpiece wobbling, misalignment, or even detachment, affecting machining accuracy and potentially damaging the equipment and cutting head. Therefore, a directional clamping mechanism for vertical grinding machine feeding is urgently needed to address these technical shortcomings. Utility Model Content

[0004] The purpose of this utility model is to provide a directional clamping mechanism for feeding materials into a vertical grinding machine, so as to solve the problem of inaccurate orientation of the clamping structure of the vertical grinding machine mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a directional clamping mechanism for feeding a vertical grinding machine, comprising a clamping table and tracks. The inner wall of the clamping table has tracks in four directions, and a clamping seat is slidably connected in each set of tracks. A rotating seat is movably connected to the center of the clamping table. A turntable is fixedly sleeved on the outside of the rotating seat. Four sets of movable arms are hinged to the outside of the turntable. A hinge block is movably hinged to the other end of each set of movable arms. The hinge block is installed at the bottom of the clamping seat. The movable arms form a cross-shaped directional clamping around the turntable. Fixed blocks are fixedly connected to the outer walls of the clamping seats on the left and right sides of the turntable, and clamping cylinders are installed laterally between the fixed blocks.

[0006] As a further technical solution of this utility model, the movable arm is "L" shaped, and the movable arm rotates above the clamping cylinder.

[0007] As a further technical solution of this utility model, the clamping platform is a circular platform, and the track is distributed around the edge of the clamping platform.

[0008] As a further technical solution of this utility model, the edge of the clamp is provided with an installation groove, and the clamp is fixedly connected to a retainer through the installation groove, and a screw is fixedly connected between the retainer and the installation groove.

[0009] As a further technical solution of this utility model, the top of the fixture extends to the surface of the clamping table, a clamping rod is movably inserted inside the fixture, and a locking bolt is fixedly connected between the fixture and the clamping rod.

[0010] As a further technical solution of this utility model, a clamping piece is fixedly connected to the end face of the clamping rod, and the clamping piece matches the shape of the material.

[0011] As a further technical solution of this utility model, a base is provided below the clamping platform, a lifting cylinder is fixedly connected to the middle of the base, a fixing plate is fixedly connected to the bottom of the piston section of the lifting cylinder, connecting rods are fixedly connected to both sides of the fixing plate, and columns are fixedly connected to the four corners of the bottom of the clamping platform, and the columns are fixedly connected to the connecting rods.

[0012] As a further technical solution of this utility model, the bottom end of the column is provided with an inner groove, and the column is sleeved on the four corners of the base for sliding and lifting.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the orientation clamping mechanism for feeding the vertical grinding machine not only realizes orientation clamping and ensures that the material is evenly stressed on all four sides, thus achieving better clamping effect for materials with irregular structures, but also achieves precise control of the gap between the material and the grinding head.

[0014] (1) By setting up clamping seats, hinge blocks, movable arms, and fixed blocks, the two sets of clamping cylinders extend, and the clamping seats on the left and right sides move outward, while the turntable rotates counterclockwise. The clamping seats are embedded in the track and move in four directions to disperse, thus opening the clamping space. When the clamping cylinders are retracted, the turntable rotates clockwise, and the four sets of movable arms pull the clamping seats toward the center of the turntable for clamping, thus completing the directional clamping. This ensures that the material is subjected to balanced force on all four sides, improves clamping stability, and quickly realizes the conversion between opening and clamping, solving the problems of inaccurate orientation and low clamping efficiency of the vertical grinding machine clamping structure.

[0015] (2) By setting up clamping rods, clamping plates and locking bolts, the clamping plates are fixedly connected to the end of the clamping rods to form a clamping interface that matches the outer contour of the material. The clamping rods can slide and adjust the clamping position in the fixture. They are fixed by tightening the locking bolts. This makes the clamping effect better for materials with irregular structures and ensures that the workpiece remains fixed in the vertical state during the feeding process.

[0016] (3) By setting up a column, base, connecting rod, fixed plate and lifting cylinder, the lifting cylinder extends to drive the fixed plate to rise, the connecting rod lifts the column and drives the clamping table to rise as a whole. Conversely, when the lifting cylinder retracts, it drives the clamping table to fall, so as to realize the overall height adjustment of the clamping table. In conjunction with the vertical position of the grinding head, the gap between the material and the grinding head can be precisely controlled. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a directional clamping mechanism for feeding a vertical grinding machine, including a clamping table 1 and a track 6. The inner wall of the clamping table 1 has a four-way track 6. Each set of track 6 is slidably connected to a clamping seat 12. The center of the clamping table 1 is movably connected to a rotating seat 20. A turntable 17 is fixedly sleeved on the outside of the rotating seat 20. Four sets of movable arms 14 are hinged to the outside of the turntable 17. The other end of each set of movable arms 14 is movably hinged to a hinge block 13. The hinge block 13 is installed at the bottom of the clamping seat 12. The movable arms 14 form a "+" shaped directional clamping around the turntable 17. Fixed blocks 15 are fixedly connected to the outer walls of the clamping seats 12 on the left and right sides of the turntable 17. Clamping cylinders 16 are installed horizontally between the fixed blocks 15. The movable arms 14 are "L" shaped and rotate above the clamping cylinders 16. The clamping table 1 is a circular table surface, and the track 6 is distributed around the edge of the clamping table 1.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the two sets of clamping cylinders 16 extend, the clamping seats 12 on the left and right sides move outward, and the turntable 17 rotates counterclockwise. When the clamping seats 12 are embedded in the track 6 and move and disperse in four directions, the clamping space is opened. When the clamping cylinders 16 are retracted, the turntable 17 rotates clockwise, and the four sets of movable arms 14 pull the clamping seats 12 toward the center of the turntable 20 for clamping, thus completing the directional clamping.

[0025] The clamp 12 has an installation groove 18 on its edge. The clamp 12 is fixedly connected to the fixture 2 through the installation groove 18. The fixture 2 is fixedly connected to the installation groove 18 with a screw 19. The top of the fixture 2 extends to the surface of the clamping table 1. A clamping rod 3 moves through the fixture 2. A locking bolt 5 is fixedly connected between the fixture 2 and the clamping rod 3. A clamping piece 4 is fixedly connected to the end face of the clamping rod 3. The clamping piece 4 matches the shape of the material.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a clamping piece 4 is fixedly connected to the end of the clamping rod 3, forming a clamping section that matches the outer contour of the material. The clamping rod 3 can slide and adjust the clamping position within the fixture 2 and is fixed by tightening the locking bolt 5. This provides better clamping effect for materials with irregular shapes.

[0027] A base 8 is provided below the clamping platform 1. A lifting cylinder 11 is fixedly connected to the middle of the base 8. A fixing plate 10 is fixedly connected to the bottom of the piston section of the lifting cylinder 11. Connecting rods 9 are fixedly connected to both sides of the fixing plate 10. Columns 7 are fixedly connected to the four corners of the bottom of the clamping platform 1. Columns 7 are fixedly connected to the connecting rods 9. An inner groove is opened at the bottom of the column 7. The column 7 is sleeved on the four corners of the base 8 and slides up and down.

[0028] Specifically, such as Figure 1 As shown, the clamping platform 1 is fixed on the column 7. The lifting cylinder 11 extends and drives the fixing plate 10 to rise. The connecting rod 9 then lifts the column 7, causing the clamping platform 1 to rise as a whole. Conversely, when the lifting cylinder 11 retracts, it drives the clamping platform 1 to fall, thus realizing the overall height adjustment of the clamping platform 1.

[0029] Working principle: The clamping platform 1 is fixed on the column 7. The lifting cylinder 11 extends and drives the fixed plate 10 to rise. The connecting rod 9 then lifts the column 7, driving the clamping platform 1 to rise. Conversely, when the lifting cylinder 11 retracts, it drives the clamping platform 1 to fall, realizing the overall height adjustment of the clamping platform 1. The clamping rod 3 is fixedly connected to the clamping piece 4, forming a clamping interface that matches the outer contour of the material. The clamping rod 3 can slide and adjust the clamping position in the fixture 2 and is fixed by tightening the locking bolt 5. When the two sets of clamping cylinders 16 extend, the clamping seats 12 on the left and right sides move outward and the turntable 17 rotates counterclockwise. When the clamping seats 12 are embedded in the track 6 and move and disperse in four directions, the clamping space is opened. When the clamping cylinders 16 retract, the turntable 17 rotates clockwise. The four sets of movable arms 14 pull the clamping seats 12 to converge and clamp towards the center of the turntable 20, completing the directional clamping and ensuring that the material is evenly stressed on all four sides.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
