Description

Technical Field

[0001] The embodiments of the present invention relate to the field of casting technology, and in particular, to a fixture for casting truck parts. Background Art

[0002] Trucks include dump trucks, tractor trucks, off-road and roadless trucks, and various specialized vehicles. These vehicles are primarily used for transporting cargo, and are sometimes also used to tow other vehicles. They fall under the commercial vehicle category. They are generally categorized by weight as heavy-duty or light-duty. The production process for existing trucks requires the use of castings to produce some of their metal components.

[0003] Patent No. CN211761048U discloses a casting fixture that extends from the inside out, including a mounting base, a clamping mechanism, and a cylinder. The mounting base includes an upper plate, a lower plate, and a vertical plate. The upper plate and the lower plate are fixedly connected to the upper and lower surfaces of the vertical plate, respectively. The upper plate and the lower plate are arranged perpendicularly and parallel to each other and the vertical plate. The clamping mechanism includes a U-shaped base, a connecting rod, and a clamping arm. The middle part of the clamping arm is provided with a rotating shaft connected to the upper plate. The rotating shaft is fixedly connected to the upper plate. The lower end of the clamping arm is provided with a connecting rod connected to the lower end of the connecting rod. The lower end of the connecting rod is rotatably connected to the U-shaped base. The bottom of the lower plate is fixedly connected to the cylinder. The output end of the cylinder passes through the lower plate and is fixedly connected to the U-shaped base. The U-shaped base, the connecting rod, and the clamping arm are movably connected to facilitate the opening and closing of the crossed clamping arms when the U-shaped base moves up and down, making it convenient to clamp some tubular parts from the inner wall, facilitating production and processing while avoiding damage to the outer surface of the workpiece.

[0004] Although the above-mentioned casting fixture can avoid clamping the workpiece during actual use, there is a problem of unstable clamping, which causes the workpiece to vibrate or shake due to external forces and other factors during the casting process, thereby affecting the quality of the workpiece, and there are certain defects. Summary of the Invention

[0005] To overcome the above-mentioned defects, an embodiment of the present invention provides a fixture for casting truck parts, which solves the technical problem in the prior art that the workpiece vibrates or shakes due to external forces during the casting process, thereby affecting the quality of the workpiece.

[0006] According to one aspect, at least one embodiment of the present invention provides a fixture for casting truck parts, comprising a body, a processing platform fixedly connected to the top surface of the body, a stabilizing mechanism provided on the top surface of the body, a discharging mechanism provided on the bottom surface of the stabilizing mechanism, and a cleaning mechanism provided on the top surface of the body; The stabilizing mechanism includes: a motor, a bidirectional screw, a support column, a clamping plate, a push block, an elastic telescopic rod, and a pressure plate. The motor is fixedly connected to the side of the machine body, the bidirectional screw is fixedly connected to the output end of the motor, the support column is threadedly connected to the circumferential surface of the bidirectional screw, the clamping plate is fixedly connected to the top surface of the support column, the push block is fixedly connected to the side of the clamping plate, the elastic telescopic rod is fixedly connected to the side of the clamping plate, and the pressure plate is fixedly connected to the end of the elastic telescopic rod away from the clamping plate.

[0007] For example, in a fixture for casting truck accessories provided by at least one embodiment of the present invention, the stabilizing mechanism also includes: a stretching fixed block, a pull rod, a magnetic plate, and a spring. The stretching fixed block is fixedly connected to the top surface of the processing platform, the pull rod is slidably connected to the inner wall of the stretching fixed block, the magnetic plate is fixedly connected to the surface of the pull rod, the spring is fixedly connected to the back of the magnetic plate, and the spring is used for resetting the pull rod after movement. The surface of the magnetic plate contacts the inner wall of the processing platform and is connected to the spring, which is sleeved on the circumferential surface of the pull rod. The motor drives the bidirectional screw to rotate. , so that the support column moves toward the processing platform on the bidirectional screw, so that the clamping plate is clamped toward the processing platform, thereby pushing the elastic telescopic rod, pushing the pressure plate to clamp the workpiece, clamping the parts while preventing damage, and facilitating further processing of the fixed workpiece; when the clamping plate is clamped toward the processing platform, it drives the push block, and when the push block clamps inward, the inner wall of the push block presses the pull rod, and the pull rod pushes the magnetic plate to further clamp and fix the workpiece. When the processing is completed, the support column is retracted and removed from the push block, so that the pull rod is reset under the action of the spring force, driving the magnetic plate to reset, so that the stabilizing mechanism reciprocates to clamp the parts.

[0008] The top of the supporting plate is fixedly connected to the support column of the support column, and the bottom of the supporting plate is fixedly connected to the support column of the support column, and the bottom of the supporting plate is fixedly connected to the support column of the support column. When the push plate moves, the sponge block evenly brushes and oils the bidirectional screw, ensuring that the support column will not get stuck when sliding and can run smoothly, so that the clamping plate can clamp the processed parts, which is convenient for processing.

[0009] For example, in a fixture for casting truck parts provided by at least one embodiment of the present invention, the cleaning mechanism includes: a recovery box, a recovery port, and a push rod. The recovery box is installed on the inner wall of the top of the machine body, the recovery port is opened at the top of the recovery box, and the push rod is fixedly connected to the side of the recovery box; the cleaning mechanism also includes: a fixed plate, a slide, a sliding pressure block, and a magnet sheet. The fixed plate is fixedly connected to the side of the machine body, the slide is fixedly connected to the side of the fixed plate, the sliding pressure block is slidably connected to the surface of the slide, the magnet sheet is fixedly connected to the side of the sliding pressure block, the sliding pressure block is located on the movement trajectory of the push block, and the The magnet sheet contacts the surface of the pull rod. When the device is not started, the magnet sheet and the pull rod remain in contact and magnetized, so that the magnetic plate connected to the pull rod is magnetized again, and the residual waste after processing is attracted to the magnetic plate. When the device is running, the push block pushes inward, and the push block slope contacts the sliding pressure block slope. The sliding pressure block moves it upward along the slide, causing the magnet sheet to separate from the pull rod, demagnetizing the magnetic plate, and causing the waste to fall to the top of the processing platform, so that the waste is gathered in one place for easy cleaning; when the stabilization mechanism is operating, it is pushed into the recovery port by the magnetic plate and falls into the recovery box for unified recovery and cleaning, reducing the possibility of waste residue on the surface affecting the processing during part processing and cutting.

[0010] The beneficial effects of the embodiments of the present invention are: In the present invention, through the coordinated operation of the motor, bidirectional screw, support column, clamping plate, push block, elastic telescopic rod, pressure plate, stretching fixed block, pull rod, magnetic plate and spring, the motor drives the bidirectional screw to rotate, and the support column moves toward the processing platform, so that the clamping plate clamps inward, pushing the elastic telescopic rod to drive the pressure plate to clamp the workpiece, facilitating the fixation of the workpiece for further processing, preventing the workpiece from vibrating during processing, and improving the processing quality of the workpiece; when the push block stretches inward, the inner wall presses the pull rod, so that the magnetic plate further clamps and fixes the workpiece, preventing vibration displacement during processing, and improving the overall quality of the finished workpiece.

[0011] In the present invention, through the coordinated operation among the pull plate, push plate, slide groove one, pull buckle, slide rod, lifting rod, top plate, supporting slide plate, slide groove two, oil tank, oil lifting pulley and sponge block, the top plate lifts the workpiece, which is convenient for placing and removing the workpiece when the device is out of use, and avoids accidental injury to the operator when taking and placing the parts; and the oil lifting pulley is driven to rotate by the bidirectional screw, and the oil is penetrated into the sponge block by the oil lifting pulley, so that the sponge block brushes the bidirectional screw, thereby preventing the support column from getting stuck when moving on the bidirectional screw, and extending the service life of the stabilizing mechanism.

[0012] In the present invention, through the coordinated operation between the recycling box, recycling port, push rod, fixed plate, slide, sliding pressure block, and magnet sheet, the magnet sheet is connected to the pull rod to be magnetized, so that the magnetic plate is magnetized again, and the iron processing waste is attracted, which is convenient for unified cleaning of residues; when the push block is pushed inward, the sliding pressure block is pushed upward to separate the magnet sheet from the pull rod, and the magnetic plate is demagnetized, so that the waste is pushed into the recycling port by the magnetic plate and enters the recycling box for easy recycling, thereby preventing the waste from accumulating in one place and affecting the placement of subsequent workpieces.

[0020] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] like Figures 1 to 7As shown, it shows a fixture for casting truck parts in one embodiment of the present invention, comprising a body 1, a processing platform 2 fixedly connected to the top surface of the body 1, a stabilizing mechanism 3 provided on the top surface of the body 1, a discharging mechanism 4 provided on the bottom surface of the stabilizing mechanism 3, and a cleaning mechanism 5 provided on the top surface of the body 1; The stabilizing mechanism 3 includes: a motor 301, a bidirectional screw 302, a support column 303, a clamping plate 304, a push block 305, an elastic telescopic rod 306, and a pressure plate 307. The motor 301 is fixedly connected to the side of the body 1, the bidirectional screw 302 is fixedly connected to the output end of the motor 301, the support column 303 is threadedly connected to the circumferential surface of the bidirectional screw 302, the clamping plate 304 is fixedly connected to the top surface of the support column 303, and the push block 305 is fixedly connected to the side of the clamping plate 304. The elastic telescopic rod 306 is fixedly connected to the side of the clamping plate 304, and the pressure plate 307 is fixedly connected to the end of the elastic telescopic rod 306 away from the clamping plate 304. The motor 301 drives the bidirectional screw 302 to rotate, and the support column 303 moves toward the processing platform 2, so that the clamping plate 304 is clamped inward, pushing the elastic telescopic rod 306 to drive the pressure plate 307 to clamp the workpiece, making it convenient to fix the workpiece for further processing, preventing the workpiece from vibrating during processing, and improving the processing quality of the workpiece.

[0022] In some examples, the stabilization mechanism 3 also includes: a stretching fixed block 308, a pull rod 309, a magnetic plate 310, and a spring 311. The stretching fixed block 308 is fixedly connected to the top surface of the processing platform 2, the pull rod 309 is slidably connected to the inner wall of the stretching fixed block 308, the magnetic plate 310 is fixedly connected to the surface of the pull rod 309, and the spring 1 311 is fixedly connected to the back of the magnetic plate 310. When the push block 305 is stretched inward, the inner wall presses the pull rod 309, so that the magnetic plate 310 further clamps and fixes the workpiece to prevent vibration displacement during processing, thereby improving the overall quality of the finished workpiece. The spring 1 311 is used for resetting the pull rod 309 after movement. The surface of the magnetic plate 310 contacts the inner wall of the processing platform 2 and is connected to the spring 1 311 which is sleeved on the circumferential surface of the pull rod 309.

[0023] For example, Figures 1 to 7As shown, when the device is started, the motor 301 drives the bidirectional screw 302 to rotate, so that the support column 303 moves toward the processing platform 2 on the bidirectional screw 302, so that the clamping plate 304 clamps the processing platform 2, thereby pushing the elastic telescopic rod 306, and the push plate 307 clamps the workpiece, clamping the parts while preventing damage, and facilitating further processing of the fixed workpiece; when the clamping plate 304 clamps the processing platform 2, it drives the push block 305, and when the push block 305 clamps inward, the inner wall of the push block 305 presses the pull rod 309, and the pull rod 309 pushes the magnetic plate 310 to further clamp and fix the workpiece. When the processing is completed, the support column 303 is retracted and removed from the push block 305, so that the pull rod 309 is reset under the elastic force of the spring 311, driving the magnetic plate 310 to reset, so that the stabilizing mechanism 3 reciprocates to clamp the parts.

[0024] like Figures 1 to 7 As shown, it shows another embodiment of the present invention, the discharging mechanism 4 includes: a pull plate 401, a push plate 402, a slide groove 403, a pull buckle 404, a slide rod 405, a lifting rod 406, a top plate 407, a support slide plate 408, and a slide groove 409. The pull plate 401 is fixedly connected to the bottom of the support column 303, the push plate 402 is fixedly connected to the surface of the pull plate 401, the slide groove 403 is opened on the side of the push plate 402, and the slide rod 405 is slidably connected. On the inner wall of slide groove 1 403, the pull buckle 404 is fixedly connected to the top surface of the slide rod 405, the lifting rod 406 is fixedly connected to the surface of the slide rod 405, the top plate 407 is fixedly connected to the top surface of the lifting rod 406, and the supporting slide plate 408 is fixedly connected to the side of the lifting rod 406. Slide groove 2 409 is opened on the inner wall of the machine body 1, so that the top plate 407 lifts the workpiece, making it convenient to put in and take out the workpiece when the device is deactivated, avoiding accidental injury to the operator when taking and placing the parts. The discharging mechanism 4 also includes: an oil tank 410, an oil lifting pulley 411, and a sponge block 412. The oil tank 410 is fixedly connected to the surface of the push plate 402, the oil lifting pulley 411 is rotatably connected to the inner wall of the oil tank 410, and the sponge block 412 is fixedly connected to the top surface of the oil tank 410. The oil lifting pulley 411 is driven to rotate by the bidirectional screw 302, and the oil is invaded into the sponge block 412 by the oil lifting pulley 411, so that the sponge block 412 brushes the bidirectional screw 302 to prevent the support column 303 from getting stuck on the bidirectional screw 302, thereby extending the service life of the stabilizing mechanism 3. The supporting slide 408 is slidably connected to the inner wall of the second slide groove 409, the circumferential surface of the oil lifting pulley 411 contacts the circumferential surface of the bidirectional screw 302, and the top of the sponge block 412 contacts the circumferential surface of the bidirectional screw 302. In some examples, the cleaning mechanism 5 includes: a recycling box 501, a recycling port 502, and a push rod 503. The recycling box 501 is installed on the inner wall of the top of the body 1, the recycling port 502 is opened at the top of the recycling box 501, and the push rod 503 is fixedly connected to the side of the recycling box 501, so that the waste is pushed into the recycling port 502 by the magnetic plate 310 and enters the recycling box 501 for easy recycling, thereby preventing the waste from accumulating in one place and affecting the placement of subsequent workpieces; the cleaning mechanism 5 also includes: a fixed plate 504, a slide 505, a sliding pressure block 506, and a magnet sheet 507. The fixed plate 504 is fixedly connected to the side of the body 1. The slide 505 is fixedly connected to the side of the fixed plate 504, the sliding pressure block 506 is slidably connected to the surface of the slide 505, and the magnet piece 507 is fixedly connected to the side of the sliding pressure block 506. When the push block 305 is pushed inward, the sliding pressure block 506 is pushed upward to separate the magnet piece 507 from the pull rod 309, and the magnetic plate 310 is demagnetized. The magnet piece 507 is connected to the pull rod 309 to magnetize, so that the magnetic plate 310 is magnetized again, which attracts the iron processing waste and facilitates the unified cleaning of the residue; the sliding pressure block 506 is located on the movement trajectory of the push block 305, and the magnet piece 507 is in contact with the surface of the pull rod 309.

[0025] For example, Figures 1 to 7 As shown, when the device is started, the pull plate 401 is driven by the support column 303 to move inward, so that the pull plate 401 drives the push plate 402 to move back and forth. When the support column 303 is clamped inward, it drives the slide bar 405 to slide downward along the slide groove 1 403. At the same time, because the support slide plate 408 is limited by the slide groove 2 409, the lifting rod 406 connected to the support slide plate 408 can only move vertically up and down, so that the top plate 407 can lift and drop the workpiece, making it convenient to put the workpiece in and take it out, and preventing the workpiece from being tightly fitted to the top of the body 1, thereby affecting the clamping of the robot arm; the pull plate When 401 moves, the pulling plate 401 drives the pushing plate 402 to move, and the pushing plate 402 drives the oil tank 410. The oil lifting pulley 411 is at the top of the oil tank 410, and the oil lifting pulley 411 contacts and rubs with the bidirectional screw 302 to rotate. The oil is scooped up from the oil tank 410 by the circumferential groove of the oil lifting pulley 411 and immersed in the sponge block 412. When the pushing plate 402 moves, the sponge block 412 evenly brushes and oils the bidirectional screw 302, ensuring that the support column 303 will not get stuck when sliding and can run smoothly, so that the clamping plate 304 clamps the processed parts, facilitating processing work.

[0026] When the device is not started, the magnet piece 507 maintains contact with the pull rod 309 and magnetizes, so that the magnetic plate 310 connected to the pull rod 309 is magnetized again, and the residual waste after processing is attracted to the magnetic plate 310. When the device is running, the push block 305 pushes inward, and the inclined surface of the push block 305 contacts the inclined surface of the sliding pressure block 506. The sliding pressure block 506 moves it up along the slide 505, causing the magnet piece 507 to separate from the pull rod 309, demagnetizing the magnetic plate 310, and causing the waste to fall to the top of the processing platform 2, so that the waste can be gathered in one place for easy cleaning; when the stabilizing mechanism 3 is operating, it is pushed into the recovery port 502 by the magnetic plate 310 and falls into the recovery box 501 for unified recovery and cleaning, reducing the possibility of waste residue on the surface affecting the processing during part processing and cutting.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
