Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a position-adjustable casting cutting device. Background Technology

[0002] In many fields such as machinery manufacturing, auto parts production, and hardware processing, casting cutting is a common and critical processing step that requires removing excess parts of the casting (such as risers). The quality and efficiency of casting cutting directly affect the subsequent processing accuracy and production progress. In a patent application with publication number CN215316992U for a metal cutting machine for cutting oil pipe joints, a worktable is included. A cooling device is provided at one end of the upper surface of the worktable. A steering motor is provided at the top of the cooling device. A steering block is connected to the output end of the steering motor. A cutting mechanism is provided on one side of the steering block. The cutting mechanism includes a lead screw linear module. The driving end of the lead screw linear module is connected to the steering block. The lead screw linear module includes a slider. A horizontal support rod is connected to the side of the slider away from the steering block. A hydraulic telescopic rod is fixed at the top of the end of the horizontal support rod away from the slider. A multi-fold connecting rod is connected to the output shaft of the hydraulic telescopic rod. A movable frame is provided at the bottom of the end of the multi-fold connecting rod away from the hydraulic telescopic rod. The cutting machine is provided inside the movable frame. A reduction motor is installed on the side of the multi-fold connecting rod away from the movable frame. The output shaft of the reduction motor is connected to the movable frame. This casting cutting device uses a fixed clamping structure and cutting position. When the casting needs to be cut at different positions or angles, the position of the cutting base or cutter needs to be adjusted. However, the position of the cutting base in this cutting device can only limit the casting, and its adjustment method is relatively simple. It can only achieve position adjustment in one direction and cannot achieve flexible movement in multiple directions in the plane. Since the cutting position of the cutting base is in the left and right direction, it is not suitable for castings with complex shapes that require multi-position cutting. In addition, the inability to collect and process the chips after the casting is cut will affect the cutting quality of the casting. Utility Model Content

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 7 As shown, this utility model provides a position-adjustable casting cutting device, including a support frame 1, a processing platform 3 mounted on the support frame 1, a cutting unit 2 between the processing platform 3 and the support frame 1, a rectangular hole 33 on the processing platform 3, a sliding seat 4 inside the rectangular hole 33, a clamping unit 5 above the sliding seat 4 and located below the cutting unit 2, the sliding seat 4 and the clamping unit 5 are rotatable, an adjustment unit between the clamping unit 5 and the rectangular hole 33 for adjusting the position of the clamping unit 5, the position of the clamping unit 5 in the rectangular hole 33 can be changed by adjusting the adjustment unit, thereby adjusting the cutting position of the casting; a discharge hopper 32 corresponding to the rectangular hole 33 is provided below the processing platform 3, and a collection box 7 is provided below the discharge hopper 32, which facilitates better collection of the cut material and reduces the cleanup of the work site.

[0018] The cutting unit 2 includes a base 21, on which a hinge seat 31 is mounted and hinged. A driver 22 is mounted on top of the base 21. The driver 22 is a motor. A cutting blade 23 is provided on one side of the base 21. The cutting blade 23 is connected to the driver 22 by a belt and a drive wheel. When the driver 22 is started, the cutting blade 23 is driven to rotate at high speed through the belt and drive wheel to achieve the cutting function. A hinge rod 11 is mounted on the support frame 1. A telescopic device 24 is hinged between the base 21 and the hinge rod 11. The telescopic device 24 can be a telescopic cylinder or an electric telescopic rod. By extending and retracting the telescopic device 24, the base 21 can be rotated around the hinge point, thereby adjusting the height and angle of the cutting blade 23 to adapt to different cutting conditions.

[0019] The adjustment unit includes a transverse lead screw 41 and a longitudinal lead screw 42. The transverse lead screw 41 is arranged in the rectangular hole 33 along the left and right sides of the processing platform 3, and the longitudinal lead screw 42 is arranged in the rectangular hole 33 along the front and back directions of the processing platform 3. The transverse lead screw 41 is located above the longitudinal lead screw 42. The transverse lead screw 41 can slide along the front and back directions of the processing platform 3, and the longitudinal lead screw 42 can slide along the left and right directions of the processing platform 3. The sliding seat 4 is located at the intersection of the transverse lead screw 41 and the longitudinal lead screw 42, and the sliding seat 4 is threadedly connected to the transverse lead screw 41 and the longitudinal lead screw 42 respectively. When the transverse lead screw 41 rotates, it can drive the sliding seat 4 to move left and right along the transverse lead screw 41. When the longitudinal lead screw 42 rotates, since the transverse lead screw 41 can slide back and forth with the movement of the longitudinal lead screw 42, it drives the sliding seat 4 to move back and forth, thereby realizing the planar position adjustment of the sliding seat 4 in the rectangular hole 33.

[0020] Specifically, the inner wall of the rectangular hole 33 is provided with two symmetrically arranged first sliding grooves 331 and two second sliding grooves 332. The two first sliding grooves 331 are located below the two second sliding grooves 332. The first sliding grooves 331 and the two second sliding grooves 332 are respectively slidably provided with first sliders 333 and second sliders 334. The first sliders 333 and the second sliders 334 slide along the length direction of the sliding grooves. The two ends of the transverse lead screw 41 are rotatably engaged between the two first sliders 333, and the two ends of the longitudinal lead screw 42 are rotatably engaged between the two second sliders 334. In this embodiment, one of the first sliding grooves 331 and the second sliding groove 332 penetrate through the processing platform 3. The left end of the transverse lead screw 41 extends outward from the processing platform 3, and the front end of the longitudinal lead screw 42 extends outward from the processing platform 3. Handles are installed on the left end of the transverse lead screw 41 and the front end of the longitudinal lead screw 42 to drive the transverse lead screw 41 or the longitudinal lead screw 42 to rotate, thereby adjusting the position of the sliding seat 4.

[0021] In other embodiments, motors are installed on the outer sides of both the first slider 333 and the second slider 334. The two motors are connected to the transverse lead screw 41 and the longitudinal lead screw 42 respectively to realize the electric drive of the transverse lead screw 41 and the longitudinal lead screw 42, thereby improving the degree of automation and accuracy of adjustment.

[0022] A support plate 34 is provided below the sliding seat 4. The upper surface of the support plate 34 is in contact with the bottom surface of the sliding seat 4. Two connecting plates 341 are provided on the front and rear sides and the left and right sides of the sliding seat 4. The size of the support plate 34 is larger than the size of the sliding seat 4 so that the support plate 34 can support the sliding seat 4. The distance between two adjacent connecting plates 341 and the inner wall of the rectangular hole 33 is smaller than the width of the sliding seat 4. In this way, after the sliding seat 4 moves in the front and rear or left and right, it can always support the left and right or front and rear movement of the sliding seat 4, ensuring the smooth movement of the sliding seat 4.

[0023] The clamping unit 5 includes a mounting plate 51, and two clamps 52 are slidably arranged on the upper part of the mounting plate 51. The clamps 52 can be irregularly shaped bench vises or flexible clamps to facilitate clamping castings of any size. A slide rail 53 is provided on the upper part of the mounting plate 51, and a drive screw 54 is installed inside the slide rail 53. The two clamps 52 are threaded onto the drive screw 54, and the two clamps 52 move relative to each other through the drive screw 54 to facilitate limiting the position of the casting. One end of the drive screw 54 extends through the mounting plate 51 to the outside of the mounting plate 51. The drive of the drive screw 54 can be divided into manual and automatic modes. In the manual mode, a handle is installed on the drive end of the drive screw 54, and in the automatic mode, a motor is connected to the drive end of the drive screw 54.

[0024] A positioning post 55 is connected to the lower center of the sliding seat 4. The positioning post 55 has multiple slots 551 circumferentially arranged. A positioning groove 43 corresponding to the positioning post 55 is opened in the middle of the upper surface of the sliding seat 4. The positioning groove 43 is circular and coaxially arranged with the positioning post 55. A positioning rod 6 corresponding to the slot 551 is provided on one side of the positioning groove 43. After the positioning rod 6 is located in the slot 551, it can realize the position angle of the sliding seat 4 on the positioning post 55 and limit it. The positioning rod 6 includes a top rod 61. A stepped groove 44 is opened on one side of the positioning groove 43. The top rod 61 is located in the stepped groove 44, and the length of the top rod 61 is greater than the length of the stepped groove 44. A locking block 63 corresponding to the slot 551 is connected to the inner end of the positioning rod 6. A spring 64 sleeved on the top rod 61 is provided between the locking block 63 and the stepped groove 44. A pull handle 62 is connected to the outer end of the positioning rod 6.

[0025] When the angle of clamping unit 5 needs to be adjusted, pull handle 62, which moves push rod 61 and locking block 63 outward, causing locking block 63 to disengage from slot 551. At this time, positioning pin 55 can be rotated to adjust the angle. After the angle adjustment is completed, release pull handle 62. Under the elastic force of spring 64, locking block 63 enters the corresponding slot 551, thus fixing the angle. Working principle: The casting to be cut is placed between the two clamps 52 of the clamping unit 5. By rotating the drive screw 54 (manually rotating the handle or starting the connected motor), the two clamps 52 move relative to each other because the threads of the two clamps 52 on the drive screw 54 are opposite, thereby firmly clamping and fixing the casting and preventing the casting from shifting during the cutting process. According to the cutting requirements, when the casting needs to be positioned inside the rectangular hole 33, the horizontal lead screw 41 or the vertical lead screw 42 is driven to adjust the position of the casting in the longitudinal and transverse directions on the processing platform 3, so as to handle the riser position of castings of different sizes. At the same time, during the movement of the sliding seat 4, the support plate 34 and the connecting plate 341 always provide stable support to ensure smooth movement. If the cutting angle of the casting needs to be adjusted, pull the handle 62 of the positioning rod 6 to disengage the locking block 63 from the slot 551 on the positioning post 55, thereby releasing the constraint between the positioning post 55 and the sliding seat 4. The spring 64 is compressed under force. At this time, rotate the mounting plate 51, and the sliding seat 4 will drive the casting between the two clamping units 5 to rotate together to the required angle. After the angle of the casting is adjusted, release the handle 62. Under the elastic force of the spring 64, the locking block 63 enters the corresponding slot 551, fixing the positioning post 55 and completing the locking between the sliding seat 4 and the mounting plate 51 again, thereby fixing the angle of the casting. When cutting the casting, the driver 22 of the cutting unit 2 is started. The motor drives the belt and transmission wheel to rotate, which in turn makes the cutting blade 23 rotate at high speed. By controlling the extension and retraction of the telescopic device 24, the base 21 is driven to rotate around the hinge rod 11, and the height and angle of the cutting blade 23 are adjusted so that it contacts the position of the casting to be cut, thus completing the cutting operation.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
