Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a sample clamping device for a polishing machine. Background Technology

[0002] A sample polishing machine is a device used for grinding the surface of a sample. It is a crucial step in ensuring the quality of the sample preparation process and is widely used in the development and research of metallic materials. Traditional metallographic sample polishing machines only have components such as a base, worktable, protective cover, hydraulic system, and electrical control system. The polishing process requires the operator to manually operate the machine, which is time-consuming and labor-intensive, greatly reducing work efficiency.

[0003] According to a search, Chinese patent document, publication number CN106826557B, discloses a sample clamping device for a polishing machine. This device, with an adjustable mechanism including a spring telescopic element, controls the force and direction of the sample clamping. It achieves the functions of a traditional polishing machine and solves the problem of poor sample surface polishing quality caused by uncontrolled clamping force. It also reduces labor costs and improves work efficiency. The metal telescopic rod and spring maximize the control of the clamping force and direction, ensuring the sample surface to be polished is horizontally aligned with the polishing table and providing a suitable clamping force for better polishing quality. However, while the clamping device with its spring telescopic element can be locked with bolts, repeated disassembly and reassembly are cumbersome and time-consuming, reducing polishing efficiency. Furthermore, although the height can be adjusted by adjusting the clamping arm, manual rotation is required, which is cumbersome, inaccurate, and results in poor overall stability and a shorter service life.

[0005] To address the shortcomings of existing technologies, this utility model provides a sample clamping device for a polishing machine, which features convenient and quick sample clamping, automatic clamping, reduced manual operation difficulty and improved assembly and disassembly efficiency, as well as high overall stability and longevity, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sample clamping device for a polishing machine, comprising a worktable, a grinding table on the top side of the worktable, a fixed frame fixedly installed on the top side of the worktable, a cylinder on the top side of the fixed frame, a top plate fixedly installed at the bottom end of the cylinder, limit plates movably installed on the left and right sides of the top plate, an adjusting seat installed on the top side of the worktable by bolts, a support seat movably installed on the side of the adjusting seat near the grinding table, and a clamping plate movably installed on the top side of the support seat.

[0008] Preferably, connecting seats are fixedly installed on the left and right sides of the top plate, and limiting rods are fixedly installed on the top side of the top plate. A total of four limiting rods are provided, and a fixing frame is movably installed on the outer side of the limiting rods.

[0009] The above technical solution facilitates movement within the fixed frame under the action of four limiting rods, which improves the stability of the top plate during movement. Furthermore, the connecting seat facilitates the movement of the top plate within the limiting plate, further enhancing movement stability.

[0010] Preferably, a first sliding groove is provided on the side of the limiting plate near the top plate, a first slider is provided on the inner side of the first sliding groove, a first slider is fixedly installed on the side of the connecting seat away from the top plate, and a buffer spring is fixedly installed between the first sliding groove and the first slider.

[0011] Through the above technical solution, the starting cylinder drives the top plate and the limiting plate to move down. At this time, the limiting plate first fits against the top side of the support seat, which helps to buffer the pressure under the action of the buffer spring, improve the service life, and limit the support seat under the action of the two sets of limiting plates, further improving the stability during use.

[0012] Preferably, the adjusting seat has a second sliding groove on the side near the grinding table, and a second sliding block is provided on the inner side of the second sliding groove. The second sliding groove and the second sliding block are a set, and a total of four sets are provided. A return spring is fixedly installed between the second sliding groove and the second sliding block.

[0013] Through the above technical solution, during the grinding process, the clamping plate and support seat can easily move telescopically under the action of the return spring, thereby facilitating the adjustment of the height of the sample and the grinding table, thus making it convenient and quick to adjust the grinding height. Furthermore, the stability of the movement of the clamping plate and support seat is improved by the action of the second slide groove and the second slider.

[0014] Preferably, a second slider is fixedly installed on the side of the support base near the adjusting base, a groove is formed on the top side of the support base, a limit groove is formed on the inner side of the groove, a limit block is movably installed on the inner side of the limit groove, and an electric push rod and a telescopic rod are provided on the right side of the support base.

[0015] The above technical solution activates the electric push rod to move the two sets of clamping plates relative to each other, thereby clamping and fixing the sample placed in the middle position. The installation is convenient and quick, and the clamping and unloading are performed automatically, improving the loading and unloading efficiency. Furthermore, the stability of the clamping plates during movement is improved by the action of the telescopic rod.

[0016] Preferably, a limiting block is fixedly installed on the side of the clamping plate near the limiting groove, an electric push rod and a telescopic rod are fixedly installed on the left side of the clamping plate, a matching groove is opened on the opposite side of the clamping plate, and a matching plate is fixedly installed on the opposite side of the clamping plate, the size and shape of the matching plate matching the matching groove.

[0017] The above technical solution improves the stability of the clamping position after the two sets of mating plates and mating grooves are engaged and installed, thus preventing lateral displacement and detachment during grinding, which would affect the processing effect and service life. At the same time, the movement of the limiting block inside the limiting groove further improves the stability and load-bearing strength of the clamping plate during movement.

[0018] Compared with the prior art, the present invention provides a sample clamping device for a polishing machine, which has the following advantages:

[0019] 1. This utility model uses an electric push rod to move two sets of clamping plates relative to each other, thereby clamping and fixing the sample placed in the middle position. It is convenient and quick to install, automatically clamps and unloads the sample, improving loading and unloading efficiency. During the clamping and fixing process, the two sets of mating plates and mating grooves are engaged to improve the stability of the clamping position, thus preventing lateral displacement and detachment during grinding, which would affect the processing effect and service life. Subsequently, during the grinding process, the clamping plates and support base can be easily moved by the return spring, thereby facilitating the adjustment of the height of the sample and the grinding table, and thus facilitating the adjustment of the grinding height. It is convenient and quick to use.

[0020] 2. This utility model uses a starting cylinder to drive the top plate and the limiting plate downwards. At this time, the limiting plate preferentially fits against the top side of the support base, which helps to buffer pressure under the action of the buffer spring, thereby improving service life. Furthermore, the two sets of limiting plates limit the support base, further improving stability during use. Subsequently, the limiting plate continues to move downwards and engages with the sample, thereby driving the sample, clamping plate, and support base downwards. This facilitates increasing pressure on the sample, preventing lateral displacement of the sample during grinding, and also facilitates adjustment of the grinding height, improving the convenience of grinding processing.

[0027] 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.

[0028] Example 1:

[0029] like Figure 1-5 As shown, the present invention provides a sample clamping device for a polishing machine, including a worktable 1, a grinding table 2 on the top side of the worktable 1, a fixed frame 3 fixedly installed on the top side of the worktable 1, a cylinder 4 on the top side of the fixed frame 3, a top plate 5 fixedly installed at the bottom end of the cylinder 4, limit plates 6 movably installed on the left and right sides of the top plate 5, an adjusting seat 7 installed on the top side of the worktable 1 by bolts, a support seat 8 movably installed on the side of the adjusting seat 7 near the grinding table 2, and a clamping plate 9 movably installed on the top side of the support seat 8.

[0030] Specifically, connecting seats 502 are fixedly installed on the left and right sides of the top plate 5, and limiting rods 501 are fixedly installed on the top side of the top plate 5. A total of four limiting rods 501 are provided, and a fixing frame 3 is movably installed on the outer side of the limiting rods 501. The advantage is that the four limiting rods 501 can move inside the fixing frame 3, which helps to improve the stability of the top plate 5 during movement. Furthermore, the connecting seats 502 facilitate the movement of the top plate 5 inside the limiting plate 6, further improving the stability of movement.

[0031] Specifically, a first groove 601 is formed on the side of the limiting plate 6 near the top plate 5, and a first slider is provided on the inner side of the first groove 601. A first slider is fixedly installed on the side of the connecting seat 502 away from the top plate 5, and a buffer spring is fixedly installed between the first groove 601 and the first slider. The advantage is that by starting the cylinder 4 to drive the top plate 5 and the limiting plate 6 to move downward, the limiting plate 6 will preferentially fit against the top side of the support seat 8, thereby facilitating pressure buffering under the action of the buffer spring, improving service life, and limiting the support seat 8 under the action of the two sets of limiting plates 6, further improving the stability during use.

[0032] Specifically, the adjusting seat 7 has a second sliding groove 701 on the side near the grinding table 2. A second sliding block is installed inside the second sliding groove 701. The second sliding groove 701 and the second sliding block form a set, with a total of four sets. A return spring is fixedly installed between the second sliding groove 701 and the second sliding block. The advantage is that the clamping plate 9 and the support seat 8 can easily extend and retract under the action of the return spring, thus facilitating the adjustment of the height of the sample and the grinding table 2, thereby simplifying the adjustment of the grinding height. This makes it convenient and quick to use. Furthermore, the second sliding groove 701 and the second sliding block improve the stability of the movement of the clamping plate 9 and the support seat 8.

[0033] Example 2:

[0034] like Figure 1-5 As shown, this is an improvement on the previous embodiment. Specifically, a second slider is fixedly installed on the side of the support base 8 near the adjusting base 7. A groove 801 is formed at the top side of the support base 8, and a limiting groove 802 is formed inside the groove 801. A limiting block is movably installed inside the limiting groove 802. An electric push rod 803 and a telescopic rod 804 are provided on the right side of the support base 8. The advantage is that by activating the electric push rod 803, the corresponding two sets of clamping plates 9 are moved relative to each other, thereby clamping and fixing the sample placed in the middle position. The installation is convenient and quick, and the clamping and unloading are performed automatically, improving the loading and unloading efficiency. Furthermore, the stability of the clamping plates 9 during movement is improved under the action of the telescopic rod 804.

[0035] Specifically, a limiting block is fixedly installed on the side of the clamping plate 9 near the limiting groove 802. An electric push rod 803 and a telescopic rod 804 are fixedly installed on the left side of the clamping plate 9. A matching groove 901 is opened on the opposite side of the clamping plate 9, and a matching plate 902 is fixedly installed on the opposite side of the clamping plate 9. The size and shape of the matching plate 902 match the matching groove 901. The advantage is that after the two sets of matching plates 902 are engaged with the matching groove 901, the stability of the clamping position is improved, thereby avoiding lateral displacement and fall-off during grinding, which would affect the processing effect and service life. At the same time, the movement of the limiting block inside the limiting groove 802 further improves the stability and load-bearing strength of the clamping plate 9 when it moves.

[0036] In use, the electric push rod 803 is activated to move the two sets of clamping plates 9 relative to each other, thereby clamping and fixing the sample placed in the middle position. Installation is convenient and quick, with automatic clamping and unloading, improving loading and unloading efficiency. During clamping and fixing, the two sets of mating plates 902 engage with the mating grooves 901, improving the stability of the clamping position and preventing lateral displacement and detachment during grinding, which would affect the processing effect and service life. Subsequently, during grinding, the clamping plates 9 and the support base 8 can easily extend and retract under the action of the return spring, facilitating the adjustment of the sample and the grinding process. The height of the grinding table 2 is adjusted to facilitate grinding height adjustment, making it convenient and quick to use. Then, the cylinder 4 is activated to move the top plate 5 and the limiting plate 6 downward. At this time, the limiting plate 6 first fits against the top side of the support seat 8, which helps to buffer pressure under the action of the buffer spring, improves service life, and limits the support seat 8 under the action of the two sets of limiting plates 6, further improving the stability during use. Subsequently, the limiting plate 6 continues to move downward and engages with the sample, thereby driving the sample, clamping plate 9 and support seat 8 to move downward, which facilitates increasing pressure on the sample, avoids lateral displacement of the sample during grinding, and facilitates adjustment of grinding height, improving the convenience of grinding processing.
