Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection technology for piston rod processing, and in particular to a piston rod grinding device with a diameter measuring instrument. Background Technology
[0002] The piston rod requires high precision in machining, with a surface roughness requirement of Ra 0.4-0.8μm. Therefore, multiple grinding and polishing processes are necessary during manufacturing. In addition, the piston rod's diameter must be inspected before leaving the factory. Common inspection methods include manual inspection by workers or inspection using equipment such as diameter gauges. However, piston rod grinding and diameter inspection are two separate steps without a clear and effective connection, resulting in low piston rod output per unit time. Utility Model Content
[0003] The purpose of this application is to provide a piston rod grinding device with a diameter gauge, which aims to solve the problems existing in the prior art.
[0004] This application provides a piston rod grinding device with a diameter gauge. The diameter gauge has side plates fixed to its inlet and outlet sides. Both side plates have identical, penetrating operating ports. The operating ports are circular, and annular guide rails and toothed rings are sequentially mounted on their outer circumferences, arranged from smallest to largest diameter. A grinding assembly is mounted on the annular guide rail via a slider. The grinding assembly includes a grinding wheel extending concentrically. A rotating shaft is mounted on the shaft of the grinding wheel and rotatably connected to the slider, and the rotating shaft is also connected to a grinding motor. A drive gear is mounted on the slider facing the toothed ring. The drive gear is meshed with the toothed ring, and the shaft of the drive gear is connected to a drive motor. Both the grinding motor and the drive motor are mounted on the slider.
[0005] Furthermore, multiple sliders are symmetrically mounted on a circular guide rail, and a grinding component is mounted on the circular guide rail via these sliders.
[0006] Furthermore, a grooved block is installed on the slider, and the rotating shaft of the grinding wheel is rotatably connected in the grooved block. The end of the rotating shaft is connected to a grinding motor installed outside the grooved block through a vertical shaft gear transmission group.
[0007] Furthermore, a cover plate is installed on the slider, which partially covers the drive gear, and the portion of the drive gear protruding from the cover plate meshes with the gear ring; the drive motor is installed on the outside of the cover plate, and the output shaft of the drive motor is directly connected to the drive gear.
[0008] Furthermore, a telescopic cylinder is provided between the groove block and the slider. The cylinder body of the telescopic cylinder is fixed relative to the slider, and the telescopic rod of the telescopic cylinder is fixed relative to the groove block.
[0009] Furthermore, multiple sliders are fixedly connected by an arc-shaped cover plate that matches the shape of the annular guide rail, and the arc-shaped cover plate does not contact the annular guide rail.
[0010] The beneficial effects of this utility model are: by installing grinding equipment on both sides of the diameter measuring instrument, the grinding and diameter measuring steps can be carried out simultaneously, reducing the time for workers to move materials between steps, thereby increasing the number of piston rods produced per unit time.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] like Figure 1 The image shows a piston rod grinding device with a diameter gauge, wherein the diameter gauge 1 is a standard laser diameter gauge (Lanpeng CHLP15-01 model), and its main body is as follows. Figure 4 As shown. Both the inlet and outlet sides of the diameter measuring instrument 1 are fixed with side plates 2. Both side plates 2 have the same operating port 3 that penetrates the side plates 2. The two operating ports 3 are collinear and coaxial and communicate with the testing space of the diameter measuring instrument 1. The operating ports 3 are circular.
[0019] Annular guide rails 4 and toothed rings 5 are installed around the outer periphery of the operating port 3 in ascending order of diameter. The annular guide rails 4 and toothed rings 5 are concentric with the operating port 3. A grinding assembly 7 is mounted on the annular guide rail 4 via sliders 6. The annular guide rail 4 and sliders 6 are matched (THK HCR type). Multiple sliders 6 are symmetrically mounted around the center on one annular guide rail 4, and the grinding assembly 7 is mounted on the annular guide rail 4 via the multiple sliders 6. The sliders 6 cause the grinding assembly 7 to move circumferentially along the annular guide rail 4, thereby performing circumferential grinding on the piston rod in the operating port 3. The symmetrical grinding assembly 7 always maintains a centripetal clamping state on the piston rod, ensuring uniform force on the piston rod and reducing wobbling. A stable piston rod reduces the measurement error of the diameter measuring instrument 1.
[0020] Specifically, such as Figure 2 and Figure 3 As shown, the grinding assembly 7 includes a grinding wheel 8 extending concentrically, with a rotating shaft 12 mounted on its shaft. A grooved block 9 is mounted on the slider 6, and the rotating shaft 12 of the grinding wheel 8 is rotatably connected in the grooved block 9. The end of the rotating shaft 12 is connected to a grinding motor 11 mounted outside the grooved block 9 via a vertical shaft gear transmission group 10, driving the grinding wheel 8 to rotate.
[0021] A drive gear 13 is mounted on the slider 6 facing the gear ring 5. A cover plate 14 is mounted on the slider 6, partially covering the drive gear 13. The portion of the drive gear 13 protruding from the cover plate 14 meshes with the gear ring 5. A drive motor 15 is mounted on the outside of the cover plate 14, and the output shaft of the drive motor 15 is directly connected to the drive gear 13. The drive motor 15 drives the drive gear 13 to rotate, thereby providing driving force for the movement of the slider 6.
[0022] Both the grinding motor 11 and the drive motor 15 are mounted on the slider 6. The above structure allows the drive motor 15 to be parallel to the grinding motor 11, reducing the space occupied in the plane where the annular guide rail 4 and the slider 6 are located.
[0023] In use, the piston rod enters through the operating port 3 on one side plate 2 via a conveying device and exits through the operating port 3 on the other side plate 2. During this process, the grinding components 7 at the two operating ports 3 move along the annular guide rail 4 to grind the circumference of the piston rod, or to clamp the piston rod. The piston rod moves stably in the diameter gauge 1, through which the diameter of the piston rod can be measured. The diameter of the operating port 3 and the height of the grinding wheel 8 need to be matched according to the diameter of the piston rod to be processed.
[0024] To further expand the application scope of this utility model, a telescopic cylinder (not shown in the figure) can be provided between the groove block 9 and the slider 6. The cylinder body of the telescopic cylinder is fixed relative to the slider 6, and the telescopic rod of the telescopic cylinder is fixed relative to the groove block 9. The telescopic cylinder can be a pneumatic cylinder or a hydraulic cylinder. The height of the grinding wheel 8 can be changed by the telescopic cylinder, thereby enabling the processing of piston rods of various diameters.
[0025] Furthermore, multiple sliders 6 can be fixedly connected between each other by arc-shaped cover plates that mate with the shape of the annular guide rail 4. The arc-shaped cover plates do not contact the annular guide rail 4. The arc-shaped cover plates connect adjacent sliders, and thus multiple sliders can be connected into a single unit to form a sliding body, thereby increasing the area of the "slider". Since the area of a slider is small, the structures that can be mounted are limited. Therefore, by connecting them into a sliding body, the area increases, allowing more equipment and structures to be installed on the sliding body, not just the sliders themselves. For example, a telescopic cylinder can be installed on the sliding body. In addition, the sliding body links multiple sliders together, thus requiring only one drive motor to drive the entire sliding body, i.e., multiple sliders, to move together, reducing the need for a separate power source.
[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
