An automatic grinding device for castings

Abstract

This utility model provides an automatic grinding device for castings. The X-axis slider can slide along the X-axis slide rail extension direction, the Y-axis slider can slide along the Y-axis slide rail extension direction, and the Z-axis slider can slide along the Z-axis slide rail extension direction. By moving the slider arbitrarily along the X, Y, and Z axes, the grinding head of the grinding machine can grind the casting gate at any position, making the grinding process unrestricted by the size of the casting gate or the size of the grinding wheel. When clamping the casting, the first and second jaws are each driven by a driving mechanism. When the casting is a regular cube or cuboid structure, both driving mechanisms are activated simultaneously, causing the first and second jaws to clamp one end of the casting at the same time. When clamping irregularly shaped parts, such as "convex" shaped castings, one driving mechanism is first activated to drive the two first jaws to clamp the wider part of the casting, and then another driving mechanism is activated to drive the two second jaws to clamp the narrower part of the casting, thus achieving the purpose of clamping irregularly shaped parts.

Description

Technical Field

[0001] This utility model belongs to the field of casting grinding technology, and in particular relates to an automatic casting grinding device. Background Technology

[0002] A casting grinding machine is a machine tool that uses grinding wheels to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other grinding wheels such as oilstones and abrasive belts and free abrasives. In the production of precision castings, the demolded precision castings are placed on a casting grinding machine, and the grinding wheels on the casting grinding machine are used to grind the gate of the precision castings, thereby removing the excess part at the gate of the casting.

[0003] Chinese Patent Application No. 2019221752406 discloses a precision casting gate grinding device, including a frame and internal mechanism. A silencer is installed inside the placement box to reduce mechanical noise during operation. Shock-absorbing plates are installed at both ends of the placement box to prevent noise from mechanical vibrations, solving the problem of excessive noise. A connecting shaft connects the middle of the lifting rod, allowing for timely disassembly and replacement of the grinding block in case of malfunction. Positioners are installed at the lower end of the lifting rod's inner cavity and the upper end of the support block to more accurately confirm the material's position, saving operation time and improving work efficiency. A dust collection mechanism installed at the lower end of the filter screen operates during device operation. Through the filter screen, the dust collection mechanism sucks the dirt into the waste bin and discharges it through the outlet, which is convenient and simple, improving the device's dust and dirt prevention effect.

[0004] The above patents also have the following shortcomings: In actual use, the size of the gate of some castings is larger than the grinding mold, which makes it impossible to grind the gate of the fixed casting in one go, requiring workers to manually adjust the position of the precision casting, thus increasing the labor intensity of the workers; In actual use, some castings are irregularly shaped, such as "convex" structures, which is not conducive to the clamping of irregularly shaped structures; Therefore, this utility model proposes an automatic casting grinding device to solve the above problems. Utility Model Content

[0005] This invention provides an automatic grinding device for castings, which aims to solve the problems mentioned in the background art.

[0006] This utility model is implemented as follows: an automatic grinding device for castings includes a first moving component and a second moving component.

[0007] The first moving component includes an X-axis slide rail and a Z-axis slide rail. The X-axis slide rail is provided with a matching X-axis slider. The Z-axis slide rail is fixedly provided on the X-axis slider. The Z-axis slide rail is provided with a matching Z-axis slider. A grinder is fixedly provided on the Z-axis slider.

[0008] The second moving component includes a Y-axis slide rail, a matching Y-axis slider on the Y-axis slide rail, and a first gripper and a second gripper on the Y-axis slider. The first gripper and the second gripper are each driven and clamped by a driving mechanism.

[0009] Preferably, the driving mechanism includes a motor, which is fixedly disposed on the bottom surface of the inner wall of the slider in the Y-axis direction. A first helical gear is fixedly disposed at the output end of the motor, and a second helical gear and a third helical gear are respectively disposed on the left and right sides of the first helical gear to mesh with it.

[0010] Preferably, the second helical gear is connected to the first threaded rod, and the third helical gear is connected to the second threaded rod, wherein the threads of the first threaded rod and the second threaded rod are in opposite directions.

[0011] Preferably, the inner wall of the Y-axis slider is provided with two oppositely distributed limiting blocks, the first threaded rod is rotatably connected to one of the limiting blocks, and the second threaded rod is rotatably connected to the other limiting block.

[0012] Preferably, both the first and second grippers are provided with sliders at their bottoms, and the sliders are screwed to the first threaded rod.

[0013] Preferably, it also includes a base, with the first and second movable components disposed on the top surface of the base.

[0014] Preferably, the first moving component further includes a support frame, which is fixedly disposed on the top surface of the base, and the Y-axis slide rail is disposed below the support frame and fixedly connected to the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The X-axis slide rail, Y-axis slide rail, and Z-axis slide rail are all electric slide rails. Therefore, the X-axis slider can slide along the extension direction of the X-axis slide rail, the Y-axis slider can slide along the extension direction of the Y-axis slide rail, and the Z-axis slider can slide along the extension direction of the Z-axis slide rail. By moving the X, Y, and Z axes at will, the grinding head of the grinding machine can grind the casting gate at any position, so that the grinding is not limited by the size of the casting gate and the size of the grinding mold.

[0017] 2. When clamping castings, two first jaws and two second jaws are required. Each first jaw and two second jaws are provided and distributed opposite each other. Each first jaw and two second jaws are driven by a drive mechanism to clamp the casting. When the casting is a regular cube or cuboid structure, the two drive mechanisms are activated simultaneously, so that the first jaws and two second jaws clamp one end of the casting at the same time. The four ends of the casting are clamped to ensure that the casting will not shift during grinding. When it is necessary to clamp irregularly shaped parts, such as castings with a "convex" structure, one drive mechanism is activated first to drive the two first jaws to clamp the wider part of the casting, and then another drive mechanism is activated to drive the two second jaws to clamp the narrower part of the casting. This can achieve the purpose of clamping irregularly shaped parts. Attached Figure Description

[0031] Please see Figures 1 to 4 This utility model provides a technical solution: an automatic grinding device for castings, including a first moving component 2 and a second moving component 3; the first moving component 2 includes an X-axis slide rail 22 and a Z-axis slide rail 24, the X-axis slide rail 22 is provided with a matching X-axis slider 23, the X-axis slider 23 is fixedly provided with the Z-axis slide rail 24, the Z-axis slide rail 24 is provided with a matching Z-axis slider 25, and a grinding machine 26 is fixedly provided on the Z-axis slider 25; the second moving component 3 includes a Y-axis slide rail 31, the Y-axis slide rail 31 is provided with a matching Y-axis slider 32, the Y-axis slider 32 is provided with a first gripper 33 and a second gripper 34, and the first gripper 33 and the second gripper 34 are each driven and clamped by a driving mechanism 35.

[0032] In this embodiment, the X-axis direction slide rail 22, the Y-axis direction slide rail 31, and the Z-axis direction slide rail 24 are all electric slide rails. Therefore, the X-axis direction slider 23 can slide along the extension direction of the X-axis direction slide rail 22, the Y-axis direction slider 32 can slide along the extension direction of the Y-axis direction slide rail 31, and the Z-axis direction slider 25 can slide along the extension direction of the Z-axis direction slide rail 24. By arbitrarily moving in the X-axis, Y-axis, and Z-axis directions, the grinding head of the grinding machine 26 can grind the casting gate at any position, so that the grinding is not limited by the size of the casting gate and the size of the grinding tool;

[0033] When clamping the casting, the first clamping jaw 33 and the second clamping jaw 34 are required. There are two first clamping jaws 33 and two second clamping jaws 34, which are distributed oppositely. Each of the first clamping jaw 33 and the second clamping jaw 34 is driven by a driving mechanism 35 to clamp the casting. When the clamped casting is a regular cube or cuboid structure, the two driving mechanisms 35 are started simultaneously, so that the first clamping jaw 33 and the second clamping jaw 34 clamp one end of the casting at the same time, and the four endpoints of the casting are clamped to ensure that the casting does not shift during grinding; When clamping a special-shaped part, such as a casting with a "convex" character structure, first start a driving mechanism 35 to drive the two first clamping jaws 33 to clamp the wider part of the casting, and then start another driving mechanism 35 to drive the two second clamping jaws 34 to clamp the narrower part of the casting, so as to achieve the purpose of clamping special-shaped parts.

[0034] Further, please refer to Figure 4 , the driving mechanism 35 includes a motor 351. The motor 351 is fixedly arranged on the bottom surface of the inner wall of the Y-axis direction slider 32. The output end of the motor 351 is fixedly provided with a first bevel gear 352. The left and right sides of the first bevel gear 352 are respectively provided with a second bevel gear 353 and a third bevel gear 354 that are meshed with it.

[0035] Further, please refer to Figure 4 , the second bevel gear 353 is connected to the first threaded rod 355, the third bevel gear 354 is connected to the second threaded rod 356, and the thread directions of the first threaded rod 355 and the second threaded rod 356 are opposite.

[0036] Further, please refer to Figure 4 , two oppositely distributed limiting blocks 357 are provided on the inner wall of the Y-axis direction slider 32. The first threaded rod 355 is rotationally connected to one of the limiting blocks 357, and the second threaded rod 356 is rotationally connected to the other limiting block 357.

[0037] In this embodiment, when clamping a casting, the first clamping jaws 33 and the second clamping jaws 34 are required. There are two first clamping jaws 33 and two second clamping jaws 34, which are distributed oppositely. Each of the first clamping jaws 33 and the second clamping jaws 34 is driven by a driving mechanism 35 to clamp the casting. When the clamped casting has a regular cube or cuboid structure, two driving mechanisms 35 are started simultaneously, so that the first clamping jaws 33 and the second clamping jaws 34 clamp one end of the casting at the same time, and the four end points of the casting are clamped to ensure that the casting will not shift during grinding. Specifically, when two motors 351 are started to rotate forward simultaneously, under the action of the first helical gear 352, the second helical gear 353, the third helical gear 354, the first threaded rod 355 and the second threaded rod 356, the two first clamping jaws 33 are separated. Similarly, the two second clamping jaws 34 are separated. When the two motors 351 are started to rotate reversely simultaneously, the two first clamping jaws 33 approach, and the two second clamping jaws 34 approach, so as to realize the clamping function.

[0038] When clamping a special-shaped part, such as a casting with a "convex" structure, first start one driving mechanism 35 to drive the two first clamping jaws 33 to clamp the wider part of the casting, and then start the other driving mechanism 35 to drive the two second clamping jaws 34 to clamp the narrower part of the casting. Specifically, first drive one motor 351 to rotate forward. Under the action of the first helical gear 352, the second helical gear 353, the third helical gear 354, the first threaded rod 355 and the second threaded rod 356, the two first clamping jaws 33 are separated. On the contrary, the two first clamping jaws 33 approach. By approaching or separating the two first clamping jaws 33, the wider part of the casting is clamped. Then drive the other motor 351 to drive the second clamping jaws 34 to separate or approach to clamp the narrower part of the casting.

[0039] By starting the first clamping jaws 33 and the second clamping jaws 34 simultaneously to clamp, the regular-shaped castings are clamped. By starting the first clamping jaws 33 and the second clamping jaws 34 separately to clamp, the special-shaped castings are clamped.

[0040] The function of the limit block 357 is to prevent the slider 36 from hitting the inner wall.

[0041] Further, please refer to Figure 4 , sliders 36 are provided at the bottoms of both the first clamping jaws 33 and the second clamping jaws 34, and the sliders 36 are screwed to the first threaded rod 355.

[0042] In this embodiment, one slider 36 is provided at the bottom of each of the two first clamping jaws 33. One slider 36 is screwed to the first threaded rod 355, and the other slider 36 is screwed to the second threaded rod 356. Therefore, when the threaded rod rotates, the slider 36 moves along the extending direction of the threaded rod accordingly, meeting the requirement of clamping castings of different sizes.

[0043] Further, please refer to Figure 1, further comprising a base 1, a first moving component 2 and a second moving component 3 are disposed on the top surface of the base 1.

[0044] Further, please refer to Figure 1 , the first moving component 2 further comprises a support frame 21, the support frame 21 is fixedly disposed on the top surface of the base 1, and a Y-axis direction slide rail 31 is disposed below the support frame 21 and fixedly connected to the base 1.

[0045] In this embodiment, the base 1 plays a role of support and stability; the support frame 21 also plays a role of support and stability for the grinding machine 26, and can realize the arbitrary movement of the grinding machine 26 in the X direction and the Z direction under the action of the X-axis direction slide rail 22 and the Z-axis direction slide rail 24.

[0046] The working principle and usage process of the present utility model: The X-axis direction slide rail 22, the Y-axis direction slide rail 31 and the Z-axis direction slide rail 24 are all electric slide rails, so the X-axis direction slider 23 can slide along the extending direction of the X-axis direction slide rail 22, the Y-axis direction slider 32 can slide along the extending direction of the Y-axis direction slide rail 31, and the Z-axis direction slider 25 can slide along the extending direction of the Z-axis direction slide rail 24. Through the arbitrary movement in the X-axis, Y-axis and Z-axis directions, the grinding head of the grinding machine 26 can grind the casting gate at any position, so that the grinding is not limited by the size of the casting gate and the size of the grinding tool;

[0047] When clamping the casting, the first clamping jaw 33 and the second clamping jaw 34 are needed. There are two first clamping jaws 33 and two second clamping jaws 34 respectively, and they are distributed oppositely. The first clamping jaw 33 and the second clamping jaw 34 are each driven by a driving mechanism 35 to clamp the casting. When the clamped casting is a regular cube or cuboid structure, the two driving mechanisms 35 are started simultaneously, so that the first clamping jaw 33 and the second clamping jaw 34 clamp one end of the casting at the same time, and the four end points of the casting are clamped to ensure that the casting will not shift during grinding; when clamping a special-shaped part, such as a "convex" - shaped casting, first start one driving mechanism 35 to drive the two first clamping jaws 33 to clamp the wider part of the casting, and then start the other driving mechanism 35 to drive the two second clamping jaws 34 to clamp the narrower part of the casting, so as to achieve the purpose of clamping the special-shaped part.

[0048] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
