Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a rotatable clamping device for CNC grinding machines. Background Technology

[0002] CNC grinding machines are machine tools that use CNC technology to grind the surface of workpieces using grinding wheels. Most grinding machines use high-speed rotating grinding wheels to perform grinding operations, thereby enabling the workpieces to meet the requirements of the production process.

[0003] In the prior art, such as the Chinese patent publication number CN220408364U, a workpiece clamping device for a grinding machine includes a grinding machine base and a machine body. The bottom of the machine body is fixedly connected to the top of the grinding machine base, a grinding disc is provided on the right side of the machine body, and a grinding machine is fixedly connected to the top of the grinding machine base. By setting a limiting device, a limiting block, a stabilizing block, a spring, and a limiting groove in combination, the existing metal grinding machine is solved. A metal grinding machine is a machine tool that uses an abrasive wheel to grind the surface of a metal workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding. During use, the workpiece needs to be placed on the grinding machine, clamped, and then ground. Typically, the clamping tool for the workpiece is limited by bolt adjustment. Since the workpieces vary in size, multiple bolts need to be continuously rotated to the appropriate position during clamping, which is time-consuming and inconvenient. However, existing metal grinding machines lack components for convenient workpiece clamping.

[0004] In actual production and use, although the workpiece clamping device of this type of grinding machine can clamp the workpiece during the processing, it is sometimes necessary to rotate the clamped workpiece during grinding to achieve a better grinding effect on the outer surface of the workpiece. However, the workpiece clamping device of this type of grinding machine does not have a rotation device, which makes it impossible to rotate the clamped workpiece, which may affect the grinding effect of the workpiece and result in poor performance of this device. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a rotatable clamping device for CNC grinding machines, which has excellent effects on workpiece rotation and clamping.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A rotatable clamping device for a CNC grinding machine includes a machine tool, a half-tooth disc, and a caliper head. The machine tool has a square groove inside, and a toothed disc is rotatably connected inside the square groove. A clamping base is fixedly connected to the upper surface of the toothed disc. A placement table is fixedly connected inside the clamping base. A cylinder base is fixedly connected to the outside of the clamping base. A cylinder is fixedly connected to the upper surface of the cylinder base. A circular hole is opened inside the clamping base. The output end of the cylinder passes through the circular hole and is fixedly connected to the caliper head. A clamping head is fixedly connected to the outside of the clamping base. A motor is fixedly connected inside the machine tool. A rotating hole is opened inside the machine tool. The output end of the motor passes through the rotating hole and is fixedly connected to the half-tooth disc. A base box is fixedly connected to the bottom of the machine tool. A sliding groove is opened inside the placement table.

[0007] By adopting the above technical solution, after the worker places the workpiece on the upper surface of the placement table, the cylinder is started. The cylinder begins to work, and the output end of the cylinder drives the caliper head to move to the right, clamping the workpiece between the caliper head and the gripping head, thus completing the clamping and fixing of the workpiece. Then, the motor is started, and the output end of the motor drives the half-tooth disc. When the half-tooth disc rotates, the toothed side of the half-tooth disc rotates to the vicinity of the toothed disc and engages with the toothed disc, thereby driving the toothed disc to rotate. Through the continuous rotation of the half-tooth disc, the toothed side of the half-tooth disc intermittently engages with the toothed disc, thus driving the toothed disc to rotate intermittently. This causes the toothed disc to intermittently drive the clamped workpiece to rotate intermittently. Then, the grinding machine grinds the rotating workpiece. Through the above operations, a good effect of workpiece clamping and rotation is achieved.

[0008] A further feature of this invention is that a slider is fixedly connected to the bottom of the caliper head, and the slider is slidably connected to the groove.

[0009] By adopting the above technical solution, when the caliper head is subjected to force and moves, the slider and the slide groove are slidably connected, so that the caliper head moves in a straight line along the slide groove after being subjected to force.

[0010] A further feature of this invention is that a threaded layer is fixedly connected to the upper surface of the placement platform, and the thickness of the threaded layer is two centimeters.

[0011] By adopting the above technical solution, the two-centimeter thread layer increases the frictional force generated when in contact with the workpiece, so that the workpiece remains relatively stationary when placed.

[0012] A further feature of this invention is that four limiting circular blocks are fixedly connected to the upper surface of the placement platform.

[0013] By adopting the above technical solution, the four limiting blocks play a role in limiting the workpiece placed on the upper surface of the placement table.

[0014] A further feature of this invention is that a magnetic chuck is fixedly connected to the outside of the clamping head, and the spacing between each pair of magnetic chucks is equal.

[0015] By adopting the above technical solution, when clamping the workpiece, the magnetic attraction of the magnetic chuck makes the workpiece fit tightly against the inner wall of the clamping head after being clamped.

[0016] A further feature of this invention is that a cylinder is fixedly connected to the upper surface of the toothed disc, and the spacing between any two cylinders is equal.

[0017] By adopting the above technical solution, after the motor is turned off, the worker can manually rotate the gear plate by holding the cylinder, thereby enabling the clamped workpiece to be manually rotated for fine adjustments.

[0018] A further feature of this invention is that a baffle plate is fixedly connected to the outside of the rotating hole, and a spray gun is provided inside the square groove.

[0019] By adopting the above technical solution, workers use a spray gun to blow away the iron powder generated on the upper surface of the workpiece during grinding, and the baffle plate places the blown iron powder into the interior of the rotating hole.

[0020] A further feature of this invention is that a hanging bracket is fixedly connected inside the square groove, and the hanging bracket has a hanging hole inside.

[0021] By adopting the above technical solution, the spray gun can be inserted into the hanging hole after use, and the bracket makes it easy to place the spray gun.

[0022] A further feature of this invention is that the machine tool is externally fixedly connected with baffles, and the number of baffles is three.

[0023] By adopting the above technical solution, the three baffles prevent the iron powder generated during the grinding of the workpiece from being dispersed by the airflow.

[0024] A further feature of this invention is that the machine tool has heat dissipation holes inside, and a small fan is fixedly connected inside the machine tool.

[0025] By adopting the above technical solution, a small fan blows air onto the working motor, and then the motor is cooled through the heat dissipation holes.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a machine tool, a half-tooth disc, a caliper head, a square groove, a toothed disc, a fixture base, a placement table, a cylinder base, a cylinder, a round hole, a caliper head, a motor, a rotating hole, a base box, and a sliding groove, uses the action of the cylinder to make the caliper head clamp the workpiece between the caliper head and the clamping head. Then, the action of the motor makes the half-tooth disc rotate. When the half-tooth disc rotates, it produces intermittent meshing motion with the toothed disc, which in turn drives the toothed disc to rotate intermittently. Thus, the toothed disc intermittently drives the clamped workpiece to rotate intermittently, thereby realizing the workpiece clamping and rotation.

[0028] 2. This utility model, through the arrangement of slider, threaded layer, limiting blocks, magnetic chuck, cylinder, baffle plate, spray gun, hanger, hanging hole, baffle, heat dissipation hole, and small fan, allows the caliper head to move linearly under force by sliding connection between the slider and the slide groove, preventing deviation during caliper head movement. The threaded layer increases the friction generated by contact with the workpiece, preventing the workpiece from slipping off at will. The four limiting blocks limit the workpiece. The magnetic attraction of the magnetic chuck ensures that the inner wall of the clamping head of the clamped workpiece is tightly adhered together. The worker can manually rotate the clamped workpiece by holding the cylinder. The worker uses the spray gun to blow away the iron powder generated on the upper surface of the workpiece during grinding. The baffle prevents the iron powder from being scattered by the airflow. The small fan and heat dissipation hole dissipate heat from the motor. Attached Figure Description

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Reference Figure 1-4 A rotatable clamping device for a CNC grinding machine includes the following specific embodiments:

[0037] Example 1: A rotatable clamping device for a CNC grinding machine includes a machine tool 1, a half-gear disc 2, and a caliper head 10. The machine tool 1 has a square slot 3 inside, and a gear disc 4 is rotatably connected inside the square slot 3. A clamping base 5 is fixedly connected to the upper surface of the gear disc 4. A placement table 6 is fixedly connected inside the clamping base 5. A cylinder base 7 is fixedly connected to the outside of the clamping base 5, and a cylinder 8 is fixedly connected to the upper surface of the cylinder base 7. A circular hole 9 is opened inside the clamping base 5, and the output end of the cylinder 8 passes through the circular hole 9 and is fixedly connected to the caliper head 10. A clamping head 11 is fixedly connected to the outside of the clamping base 5. A motor 12 is fixedly connected inside the machine tool 1. A rotating hole 13 is opened inside the machine tool 1, and the output end of the motor 12 passes through the rotating hole 13 and is fixedly connected to the half-gear disc 2. A base box 14 is fixedly connected to the bottom of the machine tool 1. A sliding groove 15 is opened inside the placement table 6. The cylinder 8 causes the caliper head 10 to clamp the workpiece between the caliper head 10 and the clamping head 11. The motor 12 then causes the half-tooth disk 2 to rotate. When the half-tooth disk 2 rotates, it intermittently meshes with the toothed disk 4, thereby causing the toothed disk 4 to rotate intermittently. This causes the toothed disk 4 to intermittently rotate the clamped workpiece, thus realizing the workpiece clamping and rotation.

[0038] Example 2: A slider 16 is fixedly connected to the bottom of the caliper head 10. The slider 16 is slidably connected to the slide groove 15. When the caliper head 10 is subjected to force, the slider 16 and the slide groove 15 slidably connect the caliper head 10 to move linearly along the slide groove 15 after being subjected to force. A threaded layer 17 is fixedly connected to the upper surface of the placement platform 6. The thickness of the threaded layer 17 is two centimeters. The two-centimeter threaded layer 17 increases the friction force generated when in contact with the workpiece, so that the workpiece remains relatively stationary when placed. Four limiting blocks 18 are fixedly connected to the upper surface of the placement platform 6. The four limiting blocks 18 play a limiting role for the workpiece placed on the upper surface of the placement platform 6. A magnetic chuck 19 is fixedly connected to the outside of the clamping head 11. The spacing between each pair of magnetic chucks 19 is equal. When clamping the workpiece, the magnetic attraction of the magnetic chuck 19 makes the workpiece tightly adhere to the inner wall of the clamping head 11 after being clamped.

[0039] Example 3: A cylinder 20 is fixedly connected to the upper surface of the gear disk 4. The spacing between each pair of cylinders 20 is equal. After the motor 12 is turned off, the worker can rotate the gear disk 4 by manually holding the cylinder 20 and rotating it, thereby enabling the clamped workpiece to be rotated manually with fine adjustment. Three baffles 25 are fixedly connected to the outside of the machine tool 1. The three baffles 25 prevent the iron powder generated during the grinding of the workpiece from being scattered by the airflow.

[0040] Example 4: A baffle plate 21 is fixedly connected to the outside of the rotating hole 13. A spray gun 22 is installed inside the square groove 3. The worker uses the spray gun 22 to blow away the iron powder generated on the upper surface of the workpiece during grinding. The baffle plate 21 allows the blown iron powder to enter the interior of the rotating hole 13. A bracket 23 is fixedly connected inside the square groove 3. The bracket 23 has a hanging hole 24 inside. After the spray gun 22 is used, it is inserted into the hanging hole 24. The bracket 23 facilitates the placement of the spray gun 22.

[0041] Example 5: The machine tool 1 has a heat dissipation hole 26 inside, and a small fan 27 is fixedly connected inside the machine tool 1. The small fan 27 blows air onto the working motor 12, and then dissipates heat from the motor 12 through the heat dissipation hole 26.

[0042] In this invention, after the worker places the workpiece on the upper surface of the placement table 6, the cylinder 8 is activated. The output of the cylinder 8 drives the caliper head 10 to move to the right, clamping the workpiece between the caliper head 10 and the clamping head 11, thus completing the clamping and fixing of the workpiece. Next, the motor 12 is activated, and its output drives the semi-toothed disc 2. When the semi-toothed disc 2 rotates, the toothed side of the semi-toothed disc 2 rotates to the vicinity of the toothed disc 4 and engages with it, thereby driving the rotation of the toothed disc 4. Through the continuous rotation of the semi-toothed disc 2, the toothed side of the semi-toothed disc 2 intermittently engages with the toothed disc 4, thus driving the toothed disc 4 to rotate intermittently. This causes the toothed disc 4 to intermittently rotate the clamped workpiece. Then, a grinder grinds the rotating workpiece. Through the above operations, excellent workpiece clamping and rotation effects are achieved. The sliding connection between the slider 16 and the slide groove 15 causes the caliper head 10 to move linearly under force, preventing the caliper head 10 from deviating during movement. The threaded layer 17 increases the friction generated when in contact with the workpiece, preventing the workpiece from slipping off at will. The four limiting blocks 18 limit the workpiece. The magnetic attraction of the magnetic chuck 19 makes the inner wall of the clamping head 11 of the clamped workpiece fit tightly together. The worker manually holds the cylinder 20 to achieve manual fine-tuning of the rotation of the clamped workpiece. The worker uses the spray gun 22 to blow away the iron powder generated on the upper surface of the workpiece during grinding. The baffle 25 prevents the iron powder from being scattered with the airflow. The small fan 27 and the heat dissipation hole 26 dissipate heat from the motor 12.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
