Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a rapid positioning and measuring device for shearing machines. Background Technology

[0002] In the metal sheet processing industry, shearing machines are key equipment for cutting sheet metal. Their function is to cut large-sized metal sheets to predetermined dimensions to meet the needs of different production scenarios.

[0003] In traditional shearing machine operation, when cutting sheet metal, the operator first manually draws the cutting line on the sheet metal according to the required cutting size using a ruler and marking tools. After drawing the cutting line, the operator needs to manually push the sheet metal to the cutting position of the shearing machine. Manual pushing not only consumes a lot of physical strength and is labor-intensive, but it is also difficult to ensure the uniformity of pushing force and the stability of pushing speed during the manual pushing process. It is also difficult to ensure that the cutting line on the sheet metal is accurately located under the cutting blade. In addition, manual pushing can easily cause the sheet metal to shift, thus affecting the cutting quality of the sheet metal. Therefore, we have introduced a new rapid positioning and measuring device for shearing machines. Utility Model Content

[0004] The main objective of this invention is to provide a rapid positioning and measuring device for shearing machines, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rapid positioning and measuring device for a shearing machine includes a worktable. A groove is formed on the upper left side of the worktable, and a pushing mechanism is fixedly installed inside the groove. A fixed frame is fixedly connected to the middle of the upper part of the worktable. Anti-deviation mechanisms are fixedly connected to the lower front and lower rear left ends of the fixed frame. A hydraulic cylinder is fixedly installed in the middle of the lower inner wall of the fixed frame. A cutting blade is fixedly installed at the output end of the hydraulic cylinder. A cutting opening is formed below the cutting blade. Scale strips are provided on the upper left front and upper left rear of the worktable. Support legs are fixedly connected to the four corners of the lower end of the worktable.

[0007] Preferably, the pushing mechanism includes a motor, a threaded rod is fixedly installed at the output end of the motor, a movable sleeve is movably connected to the outer surface of the threaded rod, a pushing seat is fixedly connected to the upper end of the movable sleeve, a sliding sleeve is fixedly connected to the front and rear parts of the lower end of the pushing seat, a sliding rod is inserted and connected inside the two sliding sleeves, a through limiting groove is opened at the upper right end of the pushing seat, three rotating rods are threadedly connected to the upper end of the pushing seat, and a pressure pad is fixedly connected to the lower end of each of the three rotating rods.

[0008] Preferably, the motor is fixedly installed in the middle of the left wall of the groove, and the end of the threaded rod away from the motor is movably connected to the middle of the right wall of the groove through a bearing. The left ends of both slide rods are fixedly connected to the left wall of the groove, and the right ends of both slide rods are fixedly connected to the right wall of the groove.

[0009] By adopting the above technical solution, stable control of the pushing speed is achieved through motor drive, avoiding pushing accuracy errors caused by uneven force and speed changes during manual pushing.

[0010] Preferably, the lower inner wall of the limiting groove is at the same height as the workbench surface, and all three clamping pads are located inside the limiting groove.

[0011] By adopting the above technical solution, one end of the board can be placed in the limiting groove for fixation, while the other end of the board is placed on the workbench for cutting.

[0012] Preferably, the anti-deviation mechanism includes a mounting plate, a fixing plate is fixedly connected to the right end of the mounting plate, an electric push rod is fixedly installed at the rear end of the mounting plate, a connecting block is fixedly installed at the output end of the electric push rod, a movable groove is opened at the front end of the connecting block, a movable shaft is movably connected between the upper wall and the lower wall of the movable groove, and an anti-deviation wheel is fixedly connected to the outer surface of the movable shaft.

[0013] Preferably, the right end of the fixing plate is fixedly connected to both the fixing frame and the right wall of the groove, and the connecting block is located in front of the mounting plate.

[0014] Preferably, the anti-deviation wheel is located inside the movable groove.

[0015] By adopting the above technical solution: two anti-deviation wheels form a rolling clamp on the side of the plate. The rolling clamping method matches the pushing action of the plate. The anti-deviation wheels roll synchronously with the movement of the plate. The symmetrical clamping structure formed by the two anti-deviation wheels can keep the plate on the preset path during the pushing process.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By inserting the left side of the board into the limiting groove and pressing it in place with three screw rods, and placing the right side of the board on the workbench, the motor is started, and the screw rod is rotated by the motor, causing the movable sleeve to automatically move to the right along with the pusher seat and the fixed board. This replaces the traditional manual pushing method, which not only saves manpower and reduces the labor intensity of operators, but also enables stable control of the pushing speed through motor drive, avoiding pushing accuracy errors caused by uneven force and speed changes during manual pushing. During the board's translation, the pushing length of the board can be measured by observing the scale bar, eliminating the need for operators to draw cutting lines on the board in advance. When the board is pushed to the appropriate cutting length, the motor stops running, allowing the board to stop at the target position for cutting.

[0018] 2. The anti-deviation wheels are driven by an electric push rod to move towards the board and fit against the side of the board. The two anti-deviation wheels form a rolling clamp on the side of the board. The rolling clamping method matches the pushing action of the board. The anti-deviation wheels roll synchronously with the movement of the board. The symmetrical clamping structure formed by the two anti-deviation wheels can keep the board on the preset path during the pushing process, ensuring that the board moves in a straight line and improving the cutting quality of the board.

[0033] Please see Figure 1-4 This utility model provides a technical solution:

[0034] A rapid positioning and measuring device for a shearing machine includes a worktable 1. A groove 2 is provided on the upper left side of the worktable 1. A pushing mechanism 3 is fixedly installed inside the groove 2. A fixed frame 4 is fixedly connected to the upper middle part of the worktable 1. Anti-deviation mechanisms 5 are fixedly connected to the lower front and lower rear left parts of the fixed frame 4. A hydraulic cylinder 6 is fixedly installed in the middle of the lower inner wall of the fixed frame 4. A cutting blade 7 is fixedly installed at the output end of the hydraulic cylinder 6. A cutting opening 8 is provided below the cutting blade 7. Scale bars 9 are provided on the upper front left and upper rear left parts of the worktable 1. Support legs 10 are fixedly connected to the four corners of the lower part of the worktable 1.

[0035] In this embodiment, the pushing mechanism 3 includes a motor 31. A threaded rod 32 is fixedly installed at the output end of the motor 31. A movable sleeve 33 is movably connected to the outer surface of the threaded rod 32. A pushing seat 34 is fixedly connected to the upper end of the movable sleeve 33. Sliding sleeves 35 are fixedly connected to the front and rear lower ends of the pushing seat 34. Sliding rods 36 are inserted inside the two sliding sleeves 35. A through-hole limiting groove 37 is opened at the upper right end of the pushing seat 34. Three screw threads are threadedly connected to the upper end of the pushing seat 34. The lower ends of the three rotating rods 38 are all fixedly connected to the pressure pads 39. The motor 31 is fixedly installed in the middle of the left wall of the groove 2. The end of the threaded rod 32 away from the motor 31 is movably connected to the middle of the right wall of the groove 2 through the bearing. The left ends of the two sliding rods 36 are fixedly connected to the left wall of the groove 2, and the right ends of the two sliding rods 36 are fixedly connected to the right wall of the groove 2. The lower inner wall of the limiting groove 37 is at the same height as the table surface of the worktable 1. The three pressure pads 39 are all located inside the limiting groove 37.

[0036] The above solution involves inserting the left side of the plate into the limiting groove 37 and clamping it in place with three rotating rods 38. The right side of the plate is placed on the workbench 1. By starting the motor 31, the threaded rod 32 is rotated, causing the movable sleeve 33 to automatically move to the right along with the pusher seat 34 and the fixed plate. This replaces the traditional manual pushing method, saving manpower and reducing the labor intensity of operators. Furthermore, the motor 31 can drive stable control of the pushing speed, avoiding the pushing accuracy error caused by uneven force and speed changes during manual pushing.

[0037] In this embodiment, the anti-deviation mechanism 5 includes a mounting plate 51, a fixing plate 52 is fixedly connected to the right end of the mounting plate 51, an electric push rod 53 is fixedly installed at the rear end of the mounting plate 51, a connecting block 54 is fixedly installed at the output end of the electric push rod 53, a movable groove 55 is opened at the front end of the connecting block 54, a movable shaft 56 is movably connected between the upper wall and the lower wall of the movable groove 55, an anti-deviation wheel 57 is fixedly connected to the outer surface of the movable shaft 56, the right end of the fixing plate 52 is fixedly connected to the fixing frame 4 and the right wall of the groove 2, the connecting block 54 is located in front of the mounting plate 51, and the anti-deviation wheel 57 is located inside the movable groove 55.

[0038] The above solution involves using an electric push rod 53 to drive the anti-deviation wheels 57 to move towards the board and fit against the side of the board. The two anti-deviation wheels 57 form a rolling clamp on the side of the board, and the rolling clamping method matches the pushing action of the board. The anti-deviation wheels 57 roll synchronously with the movement of the board. The symmetrical clamping structure formed by the two anti-deviation wheels 57 ensures that the board remains on the preset path during the pushing process, ensuring that the board moves in a straight line and improving the cutting quality of the board.

[0039] It should be noted that this utility model is a rapid positioning and measuring device for a shearing machine. The left side of the sheet metal is inserted into the limiting groove 37, and then the sheet metal is pressed and fixed using three rotating rods 38. The right side of the sheet metal is placed on the worktable 1. The motor 31 is started, which drives the threaded rod 32 to rotate, causing the movable sleeve 33, along with the pusher seat 34 and the fixed sheet metal, to automatically move to the right. This process replaces the traditional manual pushing method, saving manpower and reducing the operator's workload. Furthermore, the motor 31 drive allows for stable control of the pushing speed, avoiding the pushing accuracy errors caused by uneven force and speed variations during manual pushing. During the sheet metal's translation process, the operator... Personnel only need to observe the scale bar 9 to measure the pushing length of the board, without having to draw the cutting line on the board in advance. When the board is pushed to the appropriate cutting length, the motor 31 stops running, and the board will stop at the target position for cutting. In addition, during the board pushing process, the electric push rod 53 will drive the anti-deviation wheel 57 to move towards the board until it is in contact with the side of the board. The two anti-deviation wheels 57 form a rolling clamp on the side of the board. This rolling clamping method is adapted to the pushing action of the board. The anti-deviation wheels 57 will roll synchronously with the movement of the board. The symmetrical clamping structure formed by the two anti-deviation wheels 57 can keep the board moving in a straight line along the preset path during the pushing process, thus improving the cutting quality of the board.
