Description

A roll grinding machine roll adjustment device Technical Field

[0001] This utility model relates to the field of roll grinding technology, and specifically to a roll adjustment device for a roll grinding machine. Background Technology

[0002] A roll grinding machine is a metal cutting machine tool specifically designed for precision grinding of rolls in rolling mills to restore their surface geometry and finish. Roll grinding machines typically employ adjustment devices to precisely control parameters such as the roll's position, angle, and pressure, ensuring that the roll can be ground into the required shape to meet the needs of different production processes.

[0003] According to the Chinese patent "A Roll Adjustment Device for a Roll Grinding Machine" (authorization announcement number "CN220881638U"), the height of the support frame is adjusted by the cooperation of an exposed adjustment mechanism such as a first gear, a lead screw, and a second gear, thereby allowing the adjustment mechanism to install and fix the roll.

[0004] In the aforementioned application, metal chips are generated during the grinding of the rolls, which can easily cause the cut metal chips to splash onto the exposed surfaces of the first gear, lead screw, and second gear, thereby increasing the wear between the first gear, lead screw, and second gear and affecting the installation effect of the rolls.

[0005] Based on this, the present invention designs a roll adjustment device for a roll grinding machine to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a roll adjustment device for a roll grinding machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A roll adjustment device for a roll grinding machine includes a first electric guide rail, a clamping seat slidably connected to the surface of the first electric guide rail, and a protective mechanism. The protective mechanism includes a protective sleeve fixedly connected to the top of the clamping seat, a lead screw rotatably connected to the inner wall of the protective sleeve, a first servo motor fixedly connected to the inner wall of the clamping seat, the output shaft of the first servo motor fixedly connected to the bottom end of the lead screw, a placement seat slidably connected to the inner wall of the protective sleeve, the surface of the lead screw threadedly connected to the lower end of the inner wall of the placement seat, the top of the placement seat being recessed in a "V" shape, and equally spaced ball bearings rollingly connected to the top of the placement seat.

[0009] Furthermore, elastic sleeves are fixedly connected to both the front and rear ends of the clamp seat. The surface of the elastic sleeve is accordion-shaped, and the end of the elastic sleeve away from the clamp seat is fixedly connected to the end of the first electric guide rail.

[0010] Furthermore, the bottom of the placement seat is fixedly connected to several corrugated pads, and the bottom ends of the corrugated pads are fixedly connected to the top of the clamp seat.

[0011] Furthermore, the lower end of the surface of the protective sleeve is fixedly connected to a ring of support blocks, and the bottom of the support blocks is fixedly connected to the top of the clamp seat.

[0012] Furthermore, the surface of the support block is triangular.

[0013] Furthermore, the inner wall of the protective sleeve is fixedly connected with two sliding rods, and the lower end of the inner wall of the placement seat is slidably connected to the surface of the sliding rods.

[0014] Furthermore, the lower end of the surface of the clamp base is rotatably connected to four rollers, which are arranged in a rectangular pattern.

[0015] Furthermore, several scrapers, made of polyurethane components, are fixedly connected to both the front and rear ends of the fixture base. Beneficial effects

[0016] By protecting the surface of the lead screw with a protective sleeve, metal chips generated during grinding are prevented from adhering to the surface of the lead screw, reducing wear between the lead screw and the mounting seat, thus ensuring the installation effect of the roll. The ball bearings reduce the friction between the rotating roll and the mounting seat, ensuring smooth rotation of the roll.

[0017] The fixture seat is supported by rollers, and metal debris at both ends of the rollers is scraped and pushed away by scrapers, thereby reducing direct contact between metal debris and rollers and reducing the resistance to movement of the fixture seat. The surface of the first electric guide rail is protected by an accordion-shaped elastic sleeve, thereby preventing metal debris from splashing into the guide groove of the first electric guide rail and ensuring the smoothness of the first electric guide rail driving the fixture seat to adjust its position.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to Figures 1-4 of the specification. A roll adjustment device for a roll grinding machine includes a first electric guide rail 100, a clamp seat 200 slidably connected to the surface of the first electric guide rail 100, and a protective mechanism 300. The protective mechanism 300 includes a protective sleeve 301 fixedly connected to the top of the clamp seat 200, a lead screw 302 rotatably connected to the inner wall of the protective sleeve 301, a first servo motor 304 fixedly connected to the inner wall of the clamp seat 200, the output shaft of the first servo motor 304 fixedly connected to the bottom end of the lead screw 302, a placement seat 303 slidably connected to the inner wall of the protective sleeve 301, the surface of the lead screw 302 threadedly connected to the lower end of the inner wall of the placement seat 303, the top of the placement seat 303 being recessed in a "V" shape, and equally spaced ball bearings 305 rollingly connected to the top of the placement seat 303.

[0028] A worktable is fixedly connected to the bottom of the first electric guide rail 100, and a second electric guide rail is fixedly connected to the top of the worktable. A movable frame is slidably connected to the surface of the second electric guide rail. An electric push rod is fixedly connected to the upper end of the inner wall of the movable frame. A mounting base is fixedly connected to the telescopic end of the electric push rod. A grinding tool is installed on the inner wall of the mounting base. A CNC screen is installed on the top of the worktable. A second servo motor is fixedly connected to one side of the fixture seat 200. Control consoles are slidably connected to both sides of the surface of the fixture seat 200. A three-jaw chuck is rotatably connected to one side of the control console. A bidirectional lead screw is rotatably connected to the inner wall of the fixture seat 200. The lower end of the inner wall of the control console is threaded to the surface of the bidirectional lead screw. The output shaft of the second servo motor is fixedly connected to one end of the bidirectional lead screw.

[0029] It should be noted that both the first electric guide rail 100 and the second electric guide rail consist of a guide rail body, a drive motor, a transmission device, and a control system.

[0030] Transmission device: responsible for converting the rotational motion of the motor into linear motion. Common transmission methods include screw drive, belt drive, chain drive, etc.

[0031] Control System: The control system is used to control the operation of the motor, achieving precise control of the linear motion of the clamp seat 200 or the moving frame. It can set parameters such as the movement speed, stroke, and acceleration of the clamp seat 200 or the moving frame according to user needs, and monitor the linear position and status of the clamp seat 200 or the moving frame in real time through sensors, ensuring the accuracy and safety of the movement. This is a relatively common and well-known technology in this field and is not closely related to the technical problem of this application; therefore, it has not been further described.

[0032] When the CNC screen is operated and the control system on the CNC screen issues a command, the drive motor starts to run. The rotational motion of the motor is converted into linear motion of the fixture seat 200 on the first electric guide rail 100 or linear motion of the moving frame on the second electric guide rail through the transmission device.

[0033] In this embodiment of the utility model, when grinding the roll, the CNC screen is typically operated to automatically turn on the first servo motor 304. The output shaft of the first servo motor 304 rotates, driving the lead screw 302 to rotate. The rotating lead screw 302 drives the placement seat 303 to move up to a suitable height, and then the first servo motor 304 is automatically turned off. At this time, the roll is hoisted into the groove at the top of the placement seat 303, so that the surface of the roll contacts the ball bearing 305. At this time, the second servo motor is automatically turned on, and the output shaft of the second servo motor rotates, driving the bidirectional lead screw to rotate. The rotating bidirectional lead screw drives the two control consoles to move closer to each other, thereby causing the two three-jaw chucks to abut against the two ends of the roll. At this time, the worker inserts a hex wrench into the three-jaw chuck and rotates the hex wrench to clamp the surface of the roll with the clamp on the three-jaw chuck. At this time, the first electric guide rail 100 is automatically turned on. After the first electric guide rail 100 drives the clamp seat 200 to move to a suitable position on the top of the worktable, the first electric guide rail 100 is automatically turned off.

[0034] A suitable grinding cutter is installed inside the motor housing, and a coolant spraying pipe is provided around the grinding cutter. The coolant spraying pipe around the grinding cutter is a well-known technology in the field of existing roll grinding machines, and will not be described in detail here. During grinding, the grinding cutter sprays coolant onto the grinding area between the grinding cutter and the roll. The second electric guide rail and the control console are automatically activated, which in turn drives the three-jaw chuck. The second electric guide rail drives the moving frame to move to the appropriate position, and the electric push rod is automatically activated. The extension end of the electric push rod moves down, causing the mounting base and the grinding cutter to move down. The three-jaw chuck rotates, causing the roll to rotate, so that the grinding cutter grinds the rotating roll.

[0035] In this embodiment of the utility model, the protective sleeve 301 protects the surface of the lead screw 302, thereby preventing metal chips generated during grinding from adhering to the surface of the lead screw 302, reducing the wear between the lead screw 302 and the mounting seat 303, thus ensuring the installation effect of the roll. The ball bearing 305 reduces the friction between the rotating roll and the mounting seat 303, ensuring that the roll rotates smoothly.

[0036] In some embodiments, as shown in FIG2, as a preferred embodiment of the present invention, elastic sleeves 311 are fixedly connected to both the front and rear ends of the clamp base 200. The surface of the elastic sleeves 311 is accordion-shaped. The end of the elastic sleeve 311 away from the clamp base 200 is fixedly connected to the end of the first electric guide rail 100. Four rollers 309 are rotatably connected to the lower end of the surface of the clamp base 200. The four rollers 309 are arranged in a rectangular shape. Several scrapers 310 are fixedly connected to both the front and rear ends of the clamp base 200. The scrapers 310 are made of polyurethane components. Elastic sleeves 311 are also installed at the opposite ends of the second electric guide rail and the moving frame.

[0037] In this embodiment of the invention, the clamp seat 200 is supported by rollers 309, and metal debris at both ends of rollers 309 is scraped and pushed by scrapers 310, thereby reducing direct contact between metal debris and rollers 309 and reducing the resistance to movement of the clamp seat 200. The surface of the first electric guide rail 100 is protected by accordion-shaped elastic sleeves 311, thereby preventing metal debris from splashing into the guide groove of the first electric guide rail 100 and ensuring the smoothness of the first electric guide rail 100 driving the clamp seat 200 to adjust its position.

[0038] In some embodiments, as shown in FIG4, as a preferred embodiment of the present invention, a plurality of corrugated pads 306 are fixedly connected to the bottom of the placement seat 303, and the bottom ends of the corrugated pads 306 are fixedly connected to the top of the clamp seat 200. A ring-shaped distribution of support blocks 307 is fixedly connected to the lower end of the surface of the protective cylinder 301, and the bottom of the support blocks 307 is fixedly connected to the top of the clamp seat 200. The surface of the support blocks 307 is triangular. Two sliding rods 308 are fixedly connected to the inner wall of the protective cylinder 301, and the lower end of the inner wall of the placement seat 303 is slidably connected to the surface of the sliding rods 308. Both the corrugated pads 306 and the elastic sleeve 311 are rubber components. The lead screw 302, the protective cylinder 301, and the support blocks 307 are all alloy steel components. This gives the lead screw 302, the protective cylinder 301, and the support blocks 307 a high load-bearing capacity, enabling them to withstand the enormous pressure and impact generated by the rollers during operation.

[0039] In this embodiment of the utility model, because the corrugated pad 306 of the rubber component has a certain elasticity and strength, it can evenly distribute the weight of the placement seat 303, thereby enabling the placement seat 303 to stably support the roller.

[0040] It should be noted that the first electric guide rail 100, fixture seat 200, first servo motor 304, worktable, second electric guide rail, moving frame, electric push rod, mounting base, grinding tool, CNC screen, second servo motor, control console, three-jaw chuck and bidirectional lead screw mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the power supply of the first electric guide rail 100, first servo motor 304, second electric guide rail, electric push rod, CNC screen, second servo motor and control console can be powered by the built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
