[0001] The utility model relates to the field of grinding machine fixtures, in particular to an adjustable fixture for a surface grinding machine. Background Art

[0002] A grinding machine is a machine tool that uses grinding tools to grind workpieces to obtain the required shapes, sizes, and precision machined surfaces.

[0003] Grinding machines are divided into ordinary cylindrical grinding machines, traditional internal grinding machines, coordinate grinding machines, centerless grinding machines, etc. The processing operation of a grinding machine is grinding. Grinding work plays a primary role in machining. The sharpening of cutting tools and the precise manufacturing of mechanical parts all rely on grinding work. Grinding work is also a part of precision machining. At the same time, a grinding machine fixture is a fixture used on a grinding machine. The function of a grinding machine is to perform highly precise grinding with a very small rough surface and can perform high-efficiency grinding. A grinding machine can process materials with relatively high hardness such as hardened steel and cemented carbide, and can also process materials with relatively high brittleness such as glass and granite.

[0004] When using a grinding machine to grind a workpiece, it is necessary to fix the workpiece. Therefore, a tooling fixture is required. However, due to the relatively simple structure of the tooling fixture in the existing technical solution, after the workpiece is fixed by the tooling fixture, the operator cannot adjust the angle of the workpiece again, which results in limitations in the use of the tooling fixture. Summary of the Utility Model

[0005] By providing an adjustable fixture for a surface grinding machine in an embodiment of the present application, the technical problem that in the existing technical solution of the tooling fixture, due to its relatively simple structure, after the workpiece is fixed by the tooling fixture, the operator cannot adjust the angle of the workpiece again, which results in limitations in the use of the tooling fixture is solved.

[0006] The technical solution adopted in the embodiment of the present application is as follows:

[0007] An adjustable fixture for a surface grinding machine includes a base, a support plate for supporting the workpiece, a clamping device for clamping the workpiece, a rotating block arranged on the support plate, a limiting block arranged on the base, and a rotating device for driving the rotating block to rotate; two groups of the clamping devices are symmetrically arranged on the support plate; the rotating block is rotatably connected to the limiting block; the rotating device is installed on the base, and the rotating device is in transmission connection with the rotating block;

[0008] The clamping device includes a bent clamping plate, a abutting device for abutting against the workpiece, and a first driving device for driving the movement of the bent clamping plate; two sets of the abutting devices are symmetrically arranged on the bent clamping plate; the first driving device is installed on the support plate; the bent clamping plate is arranged on the driving end of the first driving device; the abutting device includes a stopper for abutting against the workpiece and a threaded rod for driving the movement of the stopper; the stopper is arranged at one end of the threaded rod; the threaded rod is threadedly connected to the bent clamping plate.

[0009] A further technical solution is that: the rotating device includes a first gear, a second gear arranged around the rotating block, and a second driving device installed on the base; the first gear is arranged on the output shaft of the second driving device; the first gear is meshed and connected to the second gear.

[0010] A further technical solution is that: the abutting device further includes a threaded handle; the threaded handle is arranged at the other end of the threaded rod.

[0011] A further technical solution is that: the first driving device is a cylinder.

[0012] A further technical solution is that: the second driving device is a motor.

[0013] A further technical solution is that: the abutting device further includes a rubber cushion block; the rubber cushion block is arranged on the stopper.

[0014] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0015] 1. Due to the arrangements of the base, the support plate, the clamping device, the rotating block, the limiting block and the rotating device, when it is necessary to fix the workpiece, first place the workpiece at the central position on the top of the support plate, and then the two sets of clamping devices work simultaneously, so that the driving ends of the first driving devices in the two sets of clamping devices extend out at the same time, push the two sets of bent clamping plates to move closer to the workpiece, and make the two sets of bent clamping plates abut against the workpiece at the same time. Then, by sequentially rotating the four sets of threaded rods, the stoppers connected to one end of each set of threaded rods abut against the workpiece at the same time. At this time, the workpiece placed on the support plate can be effectively positioned. After the workpiece is completely fixed, then drive the rotating block to rotate on the limiting block through the rotating device. At this time, the angle of the workpiece fixed between the two sets of clamping devices can be adjusted. Therefore, the practicability of the fixture is greatly improved to a certain extent.

[0016] 2. Due to the arrangement of the first gear, the second gear and the second driving device, the first gear is driven to rotate by the output shaft of the second driving device. Since the first gear is meshed with the second gear, when the first gear rotates, it can drive the second gear to rotate. Since the second gear is fixedly connected to the rotating block, and at the same time the rotating block is fixedly connected to the bottom of the support plate, when the first gear is driven to rotate by the output shaft of the second driving device, the support plate can be driven to rotate, and thus the angle of the support plate can be adjusted.

[0017] 3. Due to the arrangement of the threaded handle, rotating the threaded handle can drive the threaded rod to rotate, which is more convenient for the staff to operate.

[0018] 4. Due to the arrangement of the rubber cushion block, when the stop block abuts against the workpiece, the rubber cushion block on the stop block will contact the workpiece at this time, which can play a good role in protecting the workpiece. Description of the Drawings

Detailed Embodiments

[0024] By providing an adjustable fixture for a surface grinder in an embodiment of the present application, the technical problem in the prior art solution that the tooling fixture has a relatively simple structure, and after the workpiece is fixed by the tooling fixture, the staff cannot adjust the angle of the workpiece again, which results in limitations in the use of the tooling fixture is solved.

[0025] The technical solution in the embodiment of the present application for solving the above problems has the following general idea:

[0026] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0027] An adjustable fixture for a surface grinder, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, includes a base 1, a support plate 2 for supporting a workpiece, a clamping device 3 for clamping the workpiece, a rotating block 4 provided on the support plate 2, a limiting block 5 provided on the base 1, and a rotating device 6 for driving the rotating block 4 to rotate. Two sets of symmetrically arranged clamping devices 3 are provided on the support plate 2. The rotating block 4 is rotatably connected to the limiting block 5. The rotating device 6 is installed on the base 1, and the rotating device 6 is drivingly connected to the rotating block 4.

[0028] The clamping device 3 includes a bent clamping plate 31, a abutting device 32 for abutting against the workpiece, and a first driving device 33 for driving the bent clamping plate 31 to move. Two sets of symmetrically arranged abutting devices 32 are provided on the bent clamping plate 31. The first driving device 33 is installed on the support plate 2. The bent clamping plate 31 is provided at the driving end of the first driving device 33. The abutting device 32 includes a stopper 321 for abutting against the workpiece and a threaded rod 322 for driving the stopper 321 to move. The stopper 321 is provided at one end of the threaded rod 322. The threaded rod 322 is threadedly connected to the bent clamping plate 31.

[0029] The rotating block 4 is fixedly connected to the bottom of the support plate 2. The limiting block 5 is fixedly connected to the top of the base 1. Two sets of symmetrically arranged clamping devices 3 are fixedly connected to the top of the support plate 2. The rotating device 6 is fixedly installed on the top of the base 1, and the rotating device 6 is drivingly connected to the rotating block 4. Two sets of symmetrically arranged abutting devices 32 are fixedly connected to both ends of the bent clamping plate 31. The first driving device 33 is fixedly installed on the top of the support plate 2. The first driving device 33 is preferably a cylinder. The bent clamping plate 31 is fixedly connected to the driving end of the first driving device 33. The stopper 321 is fixedly connected to one end of the threaded rod 322.

[0030] Due to the provision of the base 1, the support plate 2, the clamping device 3, the rotating block 4, the limiting block 5 and the rotating device 6, when it is necessary to fix the workpiece, first place the workpiece at the central position on the top of the support plate 2, and then the two sets of clamping devices 3 work simultaneously, so that the first driving devices 33 in the two sets of clamping devices 3 simultaneously drive the ends to extend, push the two sets of bent clamping plates 31 to move closer to the workpiece, and make the two sets of bent clamping plates 31 simultaneously abut against the workpiece. Immediately afterwards, by sequentially rotating the four sets of threaded rods 322, the stoppers 321 connected to one end of each set of threaded rods 322 simultaneously abut against the workpiece. At this time, the workpiece placed on the support plate 2 can be effectively positioned. After the workpiece is completely fixed, then drive the rotating block 4 to rotate on the limiting block 5 through the rotating device 6. At this time, the angle of the workpiece fixed between the two sets of clamping devices 3 can be adjusted. Therefore, to a certain extent, the practicability of this fixture is greatly improved.

[0031] As Figure 4 shown, the rotating device 6 includes a first gear 61, a second gear 62 arranged around the rotating block 4 and a second driving device 63 installed on the base 1. The first gear 61 is arranged on the output shaft of the second driving device 63. The first gear 61 is meshed and connected to the second gear 62.

[0032] The second gear 62 is fixedly arranged around the rotating block 4. The second driving device 63 is fixedly installed on the top of the base 1. The second driving device 63 is preferably a motor. The first gear 61 is fixedly connected to the output shaft of the second driving device 63.

[0033] Due to the provision of the first gear 61, the second gear 62 and the second driving device 63, the first gear 61 is driven to rotate by the output shaft of the second driving device 63. Since the first gear 61 is meshed and connected to the second gear 62, when the first gear 61 rotates, it can drive the second gear 62 to rotate. Since the second gear 62 is fixedly connected to the rotating block 4, and at the same time the rotating block 4 is fixedly connected to the bottom of the support plate 2, when the first gear 61 is driven to rotate by the output shaft of the second driving device 63, the support plate 2 can be driven to rotate, and thus the angle of the support plate 2 can be adjusted.

[0034] As Figure 3 shown, the abutting device 32 further includes a threaded handle 323. The threaded handle 323 is arranged at the other end of the threaded rod 322.

[0035] The threaded handle 323 is fixedly connected to the other end of the threaded rod 322.

[0036] Due to the provision of the threaded handle 323, by rotating the threaded handle 323, the threaded rod 322 can be driven to rotate, which is more convenient for the staff to operate.

[0037] AsFigure 3 As shown, the abutting device 32 further includes a rubber cushion block 324. The rubber cushion block 324 is arranged on the stop block 321.

[0038] The rubber cushion block 324 is fixedly connected to the stop block 321.

[0039] Due to the arrangement of the rubber cushion block 324, when the stop block 321 abuts against the workpiece, the rubber cushion block 324 on the stop block 321 will contact the workpiece at this time, and thus can play a very good protective role on the workpiece.

Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
