Description

Technical Field

[0001] This utility model relates to the field of fixed beam gantry grinding machines, and in particular to a 45-degree DD integrated high-precision swivel head for fixed beam gantry grinding machines. Background Technology

[0002] A grinding machine is a machine tool that uses abrasive wheels to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive wheels and free abrasives, such as honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines. Grinding machines can process materials with high hardness, such as hardened steel and cemented carbide; they can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very low surface roughness, as well as high-efficiency grinding, such as heavy-duty grinding.

[0003] This application improves upon the existing technology, in which the grinding head of the existing 45-degree DD integrated high-precision swivel head used for fixed beam gantry grinding machines is generally fixed, which is time-consuming to disassemble and inconvenient to replace when the grinding head needs to be replaced. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 45-degree DD integrated high-precision swivel head for fixed beam gantry grinding machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A 45-degree DD integrated high-precision swivel head for a fixed-beam gantry grinding machine includes an integrated slide. A lead screw and nut seat is fixedly connected to one side of the integrated slide. A rotary table is rotatably connected to the bottom of the side of the integrated slide away from the lead screw and nut seat. A spindle box is fixedly connected to the rotary table. A spindle box cover is fixedly installed on one side of the spindle box. An electric spindle is arranged on the side of the spindle box away from the spindle box cover. A grinding head is installed on the electric spindle. A connecting seat is fixedly connected to the side of the electric spindle away from the spindle box. Symmetrically distributed locking blocks are slidably connected to both sides of the connecting seat. Threaded limiting grooves are formed on the locking blocks. A connecting sleeve is fixedly connected to the side of the grinding head near the electric spindle, and the connecting sleeve is adapted to the connecting seat. Symmetrically distributed locking grooves are formed on both sides of the connecting sleeve, and the locking grooves are adapted to the locking blocks. Symmetrically distributed connecting plates are slidably connected to both sides of the connecting sleeve. Limiting posts are threadedly connected to the inner wall of the connecting plates, and the limiting posts are adapted to the threaded limiting grooves.

[0007] By adopting the above technical solution, the connecting sleeve is locked and limited by the matching of the locking block and the locking groove, and the locking block is fixed by the matching of the limiting post and the threaded limiting groove, so as to avoid the locking block moving during the operation of the grinding head and causing connection failure.

[0008] As a further embodiment of this utility model: symmetrically distributed square grooves are provided on both sides of the connecting sleeve, the inner wall of the square groove is slidably connected to the connecting plate, and the square groove is connected to the card slot.

[0009] By adopting the above technical solution, the square groove facilitates the guidance of the connecting plate when it moves, and the square groove restricts the rotation of the connecting plate, thereby facilitating the rotation of the limiting post and its entry into the threaded limiting groove.

[0010] As a further improvement of this utility model: the connecting plate is provided with a threaded through groove, and the threaded through groove is adapted to the limiting post. The end of the limiting post near the locking block has a threaded structure, and the end of the limiting post extending out of the connecting plate has a smooth structure.

[0011] By adopting the above technical solution, the threaded structure on the limiting post allows the limiting post to enter the threaded limiting groove to limit the block.

[0012] As a further embodiment of this utility model: a second spring is sleeved on the outside of the limiting post, one end of the second spring is fixedly connected to the connecting plate, and the other end of the second spring is fixedly connected to the inner wall of the square groove.

[0013] By adopting the above technical solution, when the limiting post is disengaged from the threaded limiting groove by the second spring, it can be quickly reset.

[0014] As a further embodiment of this utility model: symmetrically distributed L-shaped connecting rods are slidably connected to both sides of the connecting seat, one end of the L-shaped connecting rod is fixedly connected to the locking block, and the other end of the L-shaped connecting rod is fixedly connected to the push block.

[0015] By adopting the above technical solution, the L-shaped connecting rod and push block facilitate the movement of the locking block.

[0016] As a further embodiment of this utility model: a first spring is fixedly connected to one side of each of the two push blocks that are close to each other, the other end of the first spring is fixedly connected to the connecting seat, and the first spring is sleeved with the L-shaped connecting rod.

[0017] By adopting the above technical solution, the first spring facilitates the reset of the locking block during installation, thereby allowing the locking block to enter the slot and limit the connection sleeve.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, during installation, pushing the grinding head causes the connecting sleeve to fit onto the outer wall of the connecting seat. The connecting sleeve presses against the locking block, causing the locking block to enter the connecting seat. The first spring deforms, and when the locking groove on the connecting sleeve and the locking block are on the same straight line, the first spring resets, causing the locking block to reset, thereby allowing the locking block to enter the locking groove and limit the connection sleeve. The first spring causes the threaded limiting groove and the limiting post to be on the same straight line. Pushing the limiting post causes the limiting post to move the connecting plate. The connecting plate causes the second spring to deform. When the limiting post reaches the threaded limiting groove, rotating the limiting post causes the limiting post to extend out of the connecting plate and enter the threaded limiting groove. The limiting post limits the threaded limiting groove, facilitating installation and disassembly, making it easy to replace the grinding head, and improving the stability of the grinding head installation.

[0028] Reference Figure 1-4 This utility model provides a 45-degree DD integrated high-precision swivel head for a fixed beam gantry grinder, including an integrated slide 1, a lead screw nut seat 2 fixedly connected to one side of the integrated slide 1, a turntable 3 rotatably connected to the bottom of the side of the integrated slide 1 away from the lead screw nut seat 2, a spindle box 5 fixedly connected to the turntable 3, a spindle box cover 4 fixedly installed on one side of the spindle box 5, an electric spindle 7 provided on the side of the spindle box 5 away from the spindle box cover 4, a grinding head 6 installed on the electric spindle 7, a connecting seat 8 fixedly connected to the side of the electric spindle 7 away from the spindle box 5, and symmetrically distributed locking blocks 12 slidably connected to both sides of the connecting seat 8, with threaded limiting grooves 13 opened on the locking blocks 12;

[0029] A connecting sleeve 14 is fixedly connected to the side of the grinding head 6 near the electric spindle 7, and the connecting sleeve 14 is adapted to the connecting seat 8. The two sides of the connecting sleeve 14 are provided with symmetrically distributed slots 17, and the slots 17 are adapted to the locking blocks 12. The two sides of the connecting sleeve 14 are slidably connected with symmetrically distributed connecting plates 18. The inner wall of the connecting plate 18 is threadedly connected with a limit post 15, and the limit post 15 is adapted to the threaded limit groove 13. The locking block 12 is adapted to the slot 17 to lock and limit the connecting sleeve 14. The locking post 15 is adapted to the threaded limit groove 13 to fix the position of the locking block 12, so as to prevent the locking block 12 from moving and causing connection failure when the grinding head 6 is working.

[0030] The connecting sleeve 14 has symmetrically distributed square grooves 19 on both sides. The inner wall of the square groove 19 is slidably connected to the connecting plate 18, and the square groove 19 is connected to the slot 17. The square groove 19 facilitates the movement of the connecting plate 18 and restricts the rotation of the connecting plate 18, thereby facilitating the rotation of the limiting post 15 and its entry into the threaded limiting groove 13.

[0031] The connecting plate 18 has a threaded groove 20, which is adapted to the limiting post 15. The end of the limiting post 15 near the block 12 has a threaded structure, and the end of the limiting post 15 extending out of the connecting plate 18 has a smooth structure. The threaded structure on the limiting post 15 allows the limiting post 15 to enter the threaded limiting groove 13 to limit the block 12.

[0032] A second spring 16 is sleeved on the outside of the limiting post 15. One end of the second spring 16 is fixedly connected to the connecting plate 18, and the other end of the second spring 16 is fixedly connected to the inner wall of the square groove 19. When the limiting post 15 is disengaged from the threaded limiting groove 13 by the second spring 16, it can quickly reset.

[0033] The connecting seat 8 has symmetrically distributed L-shaped connecting rods 9 slidably connected on both sides. One end of the L-shaped connecting rod 9 is fixedly connected to the locking block 12, and the other end of the L-shaped connecting rod 9 is fixedly connected to the push block 11. The L-shaped connecting rod 9 and the push block 11 facilitate the movement of the locking block 12.

[0034] Two push blocks 11 are fixedly connected to a first spring 10 on the side that is close to each other. The other end of the first spring 10 is fixedly connected to the connecting seat 8, and the first spring 10 is sleeved with the L-shaped connecting rod 9. The first spring 10 facilitates the reset of the locking block 12 during installation, so that the locking block 12 enters the locking groove 17 to limit the connection sleeve 14.

[0035] Working principle:

[0036] In this application, during installation, the grinding head 6 is pushed so that the connecting sleeve 14 is fitted onto the outer wall of the connecting seat 8. The connecting sleeve 14 presses against the locking block 12, causing the locking block 12 to enter the connecting seat 8. The first spring 10 deforms. When the locking groove 17 on the connecting sleeve 14 and the locking block 12 are on the same straight line, the first spring 10 resets, causing the locking block 12 to reset, thereby causing the locking block 12 to enter the locking groove 17 to limit the connecting sleeve 14. The first spring 10 causes the threaded limiting groove 13 and the limiting post 15 to be on the same straight line. Pushing the limiting post 15 causes the limiting post 15 to move the connecting plate 18. The connecting plate 18 causes the second spring 16 to deform. When the limiting post 15 reaches the threaded limiting groove 13, the limiting post 15 is rotated so that the limiting post 15 extends out of the connecting plate 18 and enters the threaded limiting groove 13. The limiting post 15 limits the threaded limiting groove 13, which facilitates installation and disassembly, facilitates the replacement of the grinding head, and improves the stability of the grinding head installation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
