Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and more specifically, to a grinding equipment for machine tool blanks. Background Technology

[0002] Machine tools are divided into lathes, drilling machines, boring machines, planing and slotting machines, and CNC machining centers, etc. They generally use a spindle to drive the workpiece and use cutting tools for cutting. Common machine tool cutting tools include cylindrical, rhomboid, and hook-shaped tools. Among them, cylindrical cutting tools are often made by grinding the outer circle of an alloy bar on a tool grinder, and then placing it on a five-axis or six-axis machining center to mill the cutting edge.

[0003] When grinding tools using a grinding mechanism, the tool blank is usually fixed and then brought into contact with the rapidly moving grinding mechanism to achieve the grinding purpose. However, existing grinding equipment uses a single-sided grinding method, while the tool is often a double-sided structure to be ground. This leads to the need to reposition and grind the other side after grinding, which greatly reduces grinding efficiency. Moreover, the lateral grinding resistance during single-sided grinding can cause the tool to tilt, thus affecting grinding accuracy. Therefore, it is necessary to develop a machine tool blank grinding equipment to solve the shortcomings of the existing technology. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a machine tool blank grinding equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a machine tool blank grinding equipment, including a grinding table, a clamping assembly movably mounted on the top of the grinding table, two grinding assemblies located on the left and right sides of the clamping assembly on the top of the grinding table, and guide grooves located at the bottom of the left and right grinding assemblies inside the grinding table.

[0006] The grinding assembly includes grinding belts disposed on the top of the grinding table and located on the left and right sides of the clamping assembly. The two grinding belts are internally driven and sleeved with drive rollers at their distal ends. The lower ends of the two drive rollers extend to the bottom of the grinding table and are driven and connected to a drive belt. The two grinding belts are internally driven and sleeved with adjusting rollers at their proximal ends. The lower ends of the two adjusting rollers extend to the bottom of the grinding table and are slidably connected to the inside of a guide groove.

[0007] As a preferred embodiment of this utility model, the top of both the transmission roller and the adjusting roller is fixedly connected with an anti-detachment plate. The anti-detachment plate is attached to the top of the grinding belt, and the outer diameter of the anti-detachment plate is larger than the outer diameter of the transmission roller and the adjusting roller.

[0008] As a preferred embodiment of this utility model, the guide groove is an incomplete arc, the center of the arc of the guide groove coincides with the center of the transmission roller, and the centers of the near ends of the two guide grooves and the centers of the two transmission rollers are on the same straight line.

[0009] As a preferred technical solution of this utility model, the grinding table has a slot located between two guide grooves inside.

The upper end of the adjusting rod extends above the mounting bracket and is fixedly connected to a first knob. The lower end of the adjusting rod extends into the interior of the mounting bracket and is rotatably connected to an anti-slip pressure head.

[0010] As a preferred embodiment of this utility model, a drive mechanism is also provided at the bottom of the grinding table. The drive mechanism is fixedly installed at the bottom of the grinding table by a bracket, and the output shaft of the drive mechanism is fixedly connected to the bottom of one of the transmission rollers.

[0011] As a preferred technical solution of this utility model, the bottom of the grinding table is slidably engaged with a linkage frame located below two guide grooves. The linkage frame has two linkage grooves, left and right, inside. The lower ends of the two adjusting rollers are slidably engaged with the inside of the linkage grooves through bearings. The distance between the far ends of the two linkage grooves is not less than the distance between the far ends of the two guide grooves, and the distance between the near ends of the two linkage grooves is not greater than the distance between the near ends of the two guide grooves.

[0012] As a preferred technical solution of this utility model, the bottom of the linkage frame is fixedly connected to a movable frame, the bottom of the grinding table is fixedly connected to two positioning frames, the movable frame is threaded with a lead screw, the two ends of the lead screw are rotatably connected to the inside of the two positioning frames, and the front end of the lead screw passes through the positioning frame and is fixedly connected to a second knob.

[0013] As a preferred technical solution of this utility model, the internal sliding engagement of the linkage frame is provided with a sliding strip located directly below the slot. The top of the sliding strip extends into the interior of the slot and is fixedly connected to the bottom of the mounting frame. The front end of the slot extends into the top of the grinding table and is fixedly connected to a handle.

[0024] 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.

[0025] like Figures 1 to 5 As shown, this utility model provides a machine tool blank grinding equipment, including a grinding table 1, a clamping assembly 2 movably installed on the top of the grinding table 1, two grinding assemblies 3 located on the left and right sides of the clamping assembly 2 on the top of the grinding table 1, and a guide groove 4 located at the bottom of the left and right grinding assemblies 3 inside the grinding table 1.

[0026] The grinding assembly 3 includes grinding belts 31 disposed on the top of the grinding table 1 and located on the left and right sides of the clamping assembly 2. The two grinding belts 31 are internally driven and sleeved with transmission rollers 32 at their far ends. The lower ends of the two transmission rollers 32 extend to the bottom of the grinding table 1 and are driven and connected to a transmission belt 35. The two grinding belts 31 are internally driven and sleeved with adjusting rollers 33 at their near ends. The lower ends of the two adjusting rollers 33 extend to the bottom of the grinding table 1 and are slidably connected to the inside of the guide groove 4. Due to the arrangement of the two grinding assemblies 3, with the cooperation of the clamping assembly 2, the two grinding assemblies 3 can simultaneously grind the left and right sides of the workpiece symmetrically, effectively improving grinding efficiency and avoiding the situation where the workpiece tilts or even falls due to grinding on one side.

[0027] The top of both the drive roller 32 and the adjusting roller 33 is fixedly connected with an anti-detachment plate 34. The anti-detachment plate 34 is attached to the top of the grinding belt 31. The outer diameter of the anti-detachment plate 34 is larger than the outer diameter of the drive roller 32 and the adjusting roller 33. Due to the setting of the anti-detachment plate 34, the grinding belt 31 can be prevented from detaching from the drive roller 32 and the adjusting roller 33.

[0028] Among them, the guide groove 4 is an incomplete arc. The center of the arc of the guide groove 4 coincides with the center of the transmission roller 32. The centers of the near ends of the two guide grooves 4 are on the same straight line as the centers of the two transmission rollers 32. Due to the setting of the guide groove 4, the distance between the near ends of the two grinding belts 31 can be changed with the cooperation of the transmission roller 32 and the adjusting roller 33. It can also ensure that the grinding belts 31 are always in a taut state. Moreover, the cooperation of the linkage frame 5 and the linkage groove 6 ensures the synchronous movement of the two grinding belts 31, thereby ensuring that the distance between the two grinding belts 31 and the workpiece is always consistent.

[0029] The grinding table 1 has a slot 11 located between two guide grooves 4 inside. The clamping assembly 2 includes a mounting bracket 21 that is slidably engaged inside the slot 11. An adjusting rod 22 is threadedly connected to the upper end of the mounting bracket 21. The upper end of the adjusting rod 22 extends above the mounting bracket 21 and is fixedly connected to a first knob 23. The lower end of the adjusting rod 22 extends into the interior of the mounting bracket 21 and is rotatably connected to an anti-slip pressure head 24.

[0030] The bottom of the grinding table 1 is also equipped with a drive mechanism. The drive mechanism is fixedly installed on the bottom of the grinding table 1 by a bracket, and the output shaft of the drive mechanism is fixedly connected to the bottom of one of the transmission rollers 32.

[0031] The bottom of the grinding table 1 is slidably engaged with a linkage frame 5 located below the two guide grooves 4. The linkage frame 5 has two linkage grooves 6 on the left and right sides. The lower ends of the two adjusting rollers 33 are slidably engaged with the inside of the linkage grooves 6 through bearings. The distance between the far ends of the two linkage grooves 6 is not less than the distance between the far ends of the two guide grooves 4, and the distance between the near ends of the two linkage grooves 6 is not greater than the distance between the near ends of the two guide grooves 4. Due to the setting of the linkage frame 5, with the cooperation of the linkage grooves 6 and the lead screw 9, the two adjusting rollers 33 can be moved simultaneously by rotating the second knob 10. Then, with the cooperation of the transmission roller 32 and the guide grooves 4, the distance between the two grinding belts 31 can be stably changed to suit the grinding of workpieces of different specifications.

[0032] Among them, the bottom of the linkage frame 5 is fixedly connected to the movable frame 7, and the bottom of the grinding table 1 is fixedly connected to the front and rear positioning frames 8. The movable frame 7 is threaded with a lead screw 9. The two ends of the lead screw 9 are rotatably connected to the inside of the two positioning frames 8. The front end of the lead screw 9 passes through the positioning frame 8 and is fixedly connected to the second knob 10. Due to the setting of the movable frame 7, under the restriction of the positioning frame 8, the movable frame 7 can be moved back and forth by rotating the lead screw 9 through the second knob 10, and then the two adjusting rollers 33 can be moved synchronously through the linkage frame 5 and the two linkage grooves 6 inside it.

[0033] The linkage frame 5 has a sliding locking strip 12 located directly below the slot 11 inside. The top of the sliding locking strip 12 extends into the slot 11 and is fixedly connected to the bottom of the mounting frame 21. The front end of the slot 11 extends to the top of the grinding table 1 and is fixedly connected to a handle 13. Due to the setting of the slot 11, with the cooperation of the sliding locking strip 12, the operator can easily and smoothly move the clamping component 2 back and forth through the handle 13, so that the two grinding belts 31 can continuously grind along the workpiece surface to improve the continuous grinding accuracy.

[0034] Working principle and usage process of this utility model:

[0035] Place the workpiece in the mounting bracket 21, turn the first knob 23 to push the anti-slip pressure head 24 down through the adjusting rod 22 until the workpiece is pressed tightly by the anti-slip pressure head 24 under the restriction of the bottom of the inner cavity of the mounting bracket 21.

[0036] Turning the second knob 10 will cause the movable frame 7 to move back and forth via the lead screw 9 under the constraint of the two positioning frames 8, which in turn will cause the linkage frame 5 to move back and forth. The movement of the linkage frame 5 will cause the two adjusting rollers 33 to move synchronously under the cooperation of the two linkage grooves 6 and the guide groove 4, and then change the distance between the two grinding belts 31 under the cooperation of the transmission roller 32, until the distance between the two grinding belts 31 is adapted to the grinding depth of the workpiece. Finally, pushing and pulling the handle 13 will cause the clamping assembly 2 and the workpiece clamped inside to move back and forth continuously via the sliding strip 12 under the constraint of the linkage frame 5 and the slot 11, so that the two grinding belts 31 can continuously grind both sides of the workpiece.
