Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of centerless grinding technology, and more specifically, to a centerless grinding machine for machining piston rod stock. Background Technology

[0002] A centerless grinder mainly consists of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. The grinding wheel is responsible for the actual grinding work, the adjusting wheel controls the rotation of the workpiece and the feed rate, and the workpiece support supports the workpiece during grinding. These three components can be combined in several ways, except when grinding is stopped, but the principle is the same.

[0003] Piston rod stock is the raw material used to manufacture piston rods. It is usually a round bar-shaped metal material. Piston rod stock processing is the process of taking the raw material (round bar-shaped metal) and processing it through a series of machining and surface treatment processes to finally produce a finished piston rod that meets the requirements of precision, strength and operating environment.

[0004] Currently, in the traditional processing mode, the feeding and unloading of piston rod stock often requires manual operation, which increases labor intensity. Due to the discontinuity and uncertainty of manual operation, production efficiency is low, reducing the automation of the processing flow. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a centerless grinding machine for processing piston rod stock, which solves the technical problem that the feeding and unloading of piston rod stock in the prior art often requires manual operation, which increases labor intensity and leads to low production efficiency and reduced automated processing due to the discontinuity and uncertainty of manual operation.

[0006] According to one aspect, at least one embodiment of this disclosure provides a centerless grinding machine for machining piston rod stock, comprising: The centerless grinding machine body has a pushing mechanism installed on its top, and a fixed seat is installed on the top of the pushing mechanism. The pushing mechanism is used to push the clamped piston rod to move out for unloading and to move in for feeding and processing. A height position adjustment assembly is fixedly installed at the end of a fixed base, and a clamping mechanism is installed at the drive end of the height position adjustment assembly for clamping the piston rod material.

[0007] For example, at least one embodiment of this disclosure provides a centerless grinding machine for machining piston rods. The pushing mechanism includes a mounting base and a guide frame. The mounting base is bolted to the top of the centerless grinding machine body. The guide frame is fixedly mounted on the top of the mounting base. An electric push rod is fixedly connected to the rear surface of the guide frame. The output end of the electric push rod is fixedly connected to a guide slide that is slidably connected to the inner cavity of the guide frame. The top side of the guide slide is fixedly connected to the right end of the fixed base.

[0008] For example, at least one embodiment of this disclosure provides a centerless grinding machine for machining piston rods, wherein a guide groove is provided on the side surface of the guide frame, and the inner cavity of the guide groove is slidably connected to the opposite ends of the guide slide.

[0009] For example, at least one embodiment of this disclosure provides a centerless grinding machine for processing piston rods, wherein the height position adjustment assembly includes a support frame and a hydraulic cylinder. The support frame is fixedly installed on the left end of the fixed seat, the hydraulic cylinder is fixedly installed on the top end of the support frame, the output end of the hydraulic cylinder is fixedly connected to the fixed frame, and a horizontal plate is fixedly installed on the bottom end of the fixed frame.

[0010] For example, at least one embodiment of this disclosure provides a centerless grinding machine for machining piston rods, wherein a guide plate is fixedly connected to the bottom side surface of the fixed frame, and the top end of the guide plate slides through the surface of the support frame.

[0011] For example, at least one embodiment of this disclosure provides a centerless grinding machine for machining piston rods. The clamping mechanism includes a dual-axis motor, a drive seat, and a threaded rod. The dual-axis motor is fixedly mounted on the top side surface of a transverse plate. A threaded column is connected to the output end of the dual-axis motor. The drive seat is threaded onto the surface of the threaded column. A push plate is fixedly mounted on the side surface of the drive seat. A clamping plate is fixedly connected to the end of the push plate. A limit shaft is rotatably connected to the bottom side surface of the clamping plate. A clamping column is fixedly connected to the end of the limit shaft. A rubber pad is fixedly connected to the end of the clamping column.

[0012] For example, at least one embodiment of this disclosure provides a centerless grinding machine for machining piston rods, wherein the bottom side of the drive seat is slidably connected to the surface of a transverse plate, and the drive seat is fixedly connected to a push plate with a U-shaped structure.

[0013] For example, at least one embodiment of this disclosure provides a centerless grinding machine for machining piston rod stock, wherein the number of clamping plates is two, and the two clamping plates are placed parallel to each other on both sides of a transverse plate.

[0014] For example, at least one embodiment of this disclosure provides a centerless grinding machine for machining piston rod stock, wherein the limiting shaft has an I-shaped cross-section and is coaxially arranged with the clamping column.

Detailed Implementation The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0020] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0021] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0022] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-3 As shown, it illustrates a centerless grinding machine for processing piston rod stock according to an embodiment of the present disclosure, including a centerless grinding machine body 1. After the centerless grinding machine body 1 starts the processing program, it performs grinding processing on the piston rod stock to be clamped. A pushing mechanism 2 is installed on the top of the centerless grinding machine body 1, and a fixed seat 3 is installed on the top of the pushing mechanism 2. The pushing mechanism 2 is used to push the clamped piston rod to move out for unloading and to move in for feeding processing. A height position adjustment component 4 is fixedly installed at the end of the fixed base 3. A clamping mechanism 5 is installed at the drive end of the height position adjustment component 4 for clamping the piston rod stock. Through the coordinated operation of the centerless grinder body 1, the push mechanism 2, the height position adjustment component 4, and the clamping mechanism 5, an automated process for the piston rod stock from feeding, positioning, processing to unloading is achieved.

[0026] Before processing, the centerless grinder body 1 is in standby mode, and all components are reset to their initial positions. The electric push rod 21 drives the guide slide 24 and the top fixed seat 3 to stop in the initial area near the feed end of the grinder body. The hydraulic cylinder 42 of the height position adjustment component 4 is in the shortest extension state, so that the transverse plate 45 of the clamping mechanism 5 is kept at a lower initial height. The dual-axis motor 51 of the clamping mechanism 5 is not started, and the two clamping plates 55 are in an open state far apart from each other, reserving space for receiving the piston rod bar. When processing needs to be started, the external feeding device transports the piston rod bar to be processed to the clamping position below the clamping mechanism 5, triggering the processing start signal. In some embodiments, the pushing mechanism 2 includes a mounting base 25 and a guide frame 22. The mounting base 25 is bolted to the top of the centerless grinder body 1. The guide frame 22 is fixedly mounted on the top of the mounting base 25. An electric push rod 21 is fixedly connected to the rear surface of the guide frame 22. The output end of the electric push rod 21 is fixedly connected to a guide slide 24 that is slidably connected to the inner cavity of the guide frame 22. The top side of the guide slide 24 is fixedly connected to the right end of the fixed base 3.

[0027] The electric push rod 21 pushes the fixedly connected guide slide 24 to slide along the inner cavity of the guide frame 22. The guide groove 23 limits and guides the sliding guide slide 24, ensuring that the guide slide 24 moves smoothly without shaking. When the guide slide 24 slides, it will drive the fixed seat 3 at the top to move synchronously. The fixed seat 3 drives the clamping mechanism 5 and the clamped piston rod to move towards the processing area of ​​the centerless grinder body 1 through the height position adjustment component 4, until the piston rod is completely entered into the processing position of the grinder. The electric push rod 21 stops extending and the rod is in the waiting state.

[0028] In some embodiments, a guide groove 23 is provided on the side surface of the guide frame 22, and the inner cavity of the guide groove 23 is slidably connected to the opposite ends of the guide slide 24.

[0029] In some embodiments, such as Figure 3As shown, the height adjustment assembly 4 includes a support frame 41 and a hydraulic cylinder 42. The support frame 41 is fixedly installed on the left end of the fixed base 3. The hydraulic cylinder 42 is fixedly installed on the top of the support frame 41. The output end of the hydraulic cylinder 42 is fixedly connected to a fixed frame 44. A horizontal plate 45 is fixedly installed on the bottom end of the fixed frame 44. The output end of the hydraulic cylinder 42 extends outward, driving the fixed frame 44 to rise synchronously. Since the guide plate 43 on the bottom side surface of the fixed frame 44 slides through the surface of the support frame 41, the guide plate 43 will slide smoothly along the through hole of the support frame 41, avoiding deviation during the lifting and lowering of the fixed frame 44. When the fixed frame 44 rises, it will drive the horizontal plate 45 fixed at the bottom and the clamping mechanism 5 on the horizontal plate 45 to rise synchronously until the clamping column 57 of the clamping mechanism 5 is at the same horizontal height as the end of the piston rod to be processed. The hydraulic cylinder 42 stops working. After the height adaptation is completed, it is ready for positioning in the subsequent clamping action.

[0030] In some embodiments, a guide plate 43 is fixedly connected to the bottom side surface of the fixed frame 44, and the top end of the guide plate 43 slides through the surface of the support frame 41. The guide plate 43 will slide smoothly along the through hole of the support frame 41 to prevent the fixed frame 44 from shifting during the lifting and lowering process.

[0031] In some embodiments, the clamping mechanism 5 includes a dual-axis motor 51, a drive seat 52, and a threaded rod 53. The dual-axis motor 51 is fixedly mounted on the top surface of the transverse plate 45. A threaded column is connected to the output end of the dual-axis motor 51. The drive seat 52 is threadedly sleeved on the surface of the threaded column. A push plate 54 is fixedly mounted on the side surface of the drive seat 52. A clamping plate 55 is fixedly connected to the end of the push plate 54. A limit shaft 56 is rotatably connected to the bottom side surface of the clamping plate 55. A clamping column 57 is fixedly connected to the end of the limit shaft 56. A rubber pad 58 is fixedly connected to the end of the clamping column 57. After the height adjustment is completed, the output end of the dual-axis motor 51 drives the threaded column to rotate. The rotation of the threaded column synchronously drives the drive seat 52 to move linearly along the surface of the transverse plate 45. The drive seat 52 drives the push plate 54 to move. The push plate 54 will drive the two parallel clamping plates 55 at the end to move closer together. The clamping plates 55 drive the clamping column 57 to move through the limit rotating shaft 56. The clamping column 57 is in close contact with the end of the piston rod through the rubber pad 58. The dual-axis motor 51 stops working. The clamping column 57 firmly clamps the piston rod through the rubber pad 58. At the same time, the rubber pad 58 can avoid damage to the surface of the rod caused by hard contact.

[0032] In some embodiments, the bottom side of the drive seat 52 is slidably connected to the surface of the transverse plate 45, and the drive seat 52 is fixedly connected to a push plate 54 with a U-shaped structure.

[0033] In some embodiments, there are two clamping plates 55, which are placed parallel to each other on both sides of the transverse plate 45.

[0034] In some embodiments, the limiting shaft 56 has an I-shaped cross-section, and the limiting shaft 56 is coaxially arranged with the clamping column 57.

[0035] In some embodiments, there are two clamping posts 57, which are symmetrically distributed about the piston rod material. The clamping posts 57 are in contact with the end of the piston rod material through surface-mounted rubber pads 58.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
