Description

Technical Field

[0001] This invention relates to workpiece processing technology, and more specifically to a steel clamping block for processing thin-walled workpieces. Background Technology

[0002] When machining thin-walled workpieces, in order to prevent them from shifting and affecting the machining quality, it is necessary to fix them by connecting a clamping block through a lifting device.

[0003] Existing clamping blocks have relatively simple functions and lack adjustment capabilities when fixing workpieces. Consequently, they are not suitable for workpieces of different sizes, shapes, and types of processing, resulting in a limited range of applications and failing to meet the requirements of workpiece manufacturers. Therefore, this solution proposes a steel clamping block for processing thin-walled workpieces. Summary of the Invention

[0004] The purpose of this invention is to provide a steel clamping block for machining thin-walled workpieces, so as to overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel clamping block for processing thin-walled workpieces, comprising a fixed base and multiple pressure plates. The fixed base is equipped with a position adjustment mechanism, a space adjustment mechanism, and a drive mechanism. The position adjustment mechanism includes multiple sliding grooves radially extending through the fixed base, multiple sliders respectively installed inside the multiple sliding grooves, and multiple displacement components for respectively driving the multiple sliders to move. The space adjustment mechanism includes multiple threaded sleeves respectively installed at the bottom of the multiple sliders and screws respectively screwed into the multiple threaded sleeves. The threaded sleeves are arranged along the height direction of the fixed base. The bottom ends of the multiple screws are respectively fixedly connected to the tops of the multiple pressure plates. The output ends of the drive mechanism are respectively connected to the multiple threaded sleeves.

[0006] Furthermore, the fixing seat has a cylindrical structure, and the plurality of the sliding grooves are evenly distributed along the circumference of the fixing seat.

[0007] Furthermore, each of the multiple sliding grooves is provided with a limiting groove parallel to it on one side. The limiting groove is connected to the sliding groove. A limiting block is fixed to the outer wall of the slider and slides on the inner wall of the limiting groove.

[0008] Furthermore, the displacement assembly includes a lead screw rotatably connected to its inner wall along the length of the groove and a handle fixed to one end of the lead screw extending to the outside of the fixed seat, the slider being screwed to the outside of the lead screw.

[0009] Furthermore, a fixing bolt is screwed into the inside of the handle along the axial direction of the lead screw. The fixing bolt passes through the handle, and one end of the fixing bolt abuts against the outer wall of the fixing seat.

[0010] Furthermore, a telescopic rod parallel to the threaded sleeve is provided on one side, the fixed end of the telescopic rod is fixedly connected to the bottom of the slider, and the extended end of the telescopic rod is fixedly connected to the top of the pressure plate.

[0011] Furthermore, the number of the pressing plate, sliding groove, slider, displacement component and screw sleeve is four. The driving mechanism includes a motor mounted on the top of the fixed base, four transmission shafts arranged radially inside the fixed base, four connecting sleeves respectively mounted on the outside of the four transmission shafts, a linkage component for driving the four transmission shafts to rotate, and four transmission components for driving the four screw sleeves to rotate synchronously. The four transmission shafts are respectively arranged along the length direction of the four sliding grooves, and the outside of each of the four transmission shafts is rotatably connected to a fixing block fixed to the bottom of the fixed base.

[0012] Furthermore, the linkage includes a first bevel gear fixed to the output end of the motor and four second bevel gears fixed to one end of the four transmission shafts near the motor, wherein the first bevel gear meshes with the four second bevel gears respectively.

[0013] Furthermore, a key pin is fixedly connected to the outer wall of the drive shaft along its axial direction, and a keyway is opened on the inner wall of the connecting sleeve along its axial direction, with the key pin slidingly engaged inside the keyway.

[0014] Furthermore, the transmission component includes a connecting block rotatably connected to the outside of the connecting sleeve and two third bevel gears respectively sleeved on the outside of the connecting sleeve and the threaded sleeve. The connecting block has a U-shaped structure and is also rotatably connected to the outside of the threaded sleeve. The top of the connecting block is fixedly connected to the bottom of the slider.

[0015] Compared with the prior art, the present invention provides a steel clamping block for processing thin-walled workpieces. The drive mechanism drives four screw sleeves to rotate synchronously, which in turn drives multiple screws to move downward synchronously. The pressure plate moves downward accordingly, thereby adjusting the space between the workpiece below the pressure plate and the fixed seat, which further facilitates different types of processing of the workpiece below the pressure plate.

[0016] By driving the screw sleeve, screw and pressure plate to move synchronously, the position of the pressure plate can be adjusted according to the size of the workpiece. In addition, multiple screws can be adjusted separately, so the position of the four pressure plates can be adjusted individually, thus enabling the fixing of workpieces of different shapes.

[0017] After the slider moves, the connecting block drives the connecting sleeve to move synchronously, so that the third bevel gear outside the connecting sleeve and the third bevel gear outside the threaded sleeve always remain engaged, and the transmission shaft always drives the connecting sleeve to rotate. Furthermore, after the threaded sleeve moves, the drive mechanism can always drive the threaded sleeve to rotate normally. Therefore, the adjustment of the space between the workpiece below the pressure plate and the fixed seat and the adjustment of the pressure plate position can be carried out simultaneously or separately, which further improves the functionality of the pressure block.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-5A steel clamping block for processing thin-walled workpieces includes a fixed base 1 and multiple pressure plates 2. The fixed base 1 is connected to an external lifting device. The lifting device drives the fixed base 1 to move up and down, thereby driving the pressure plates 2 to fix and clamp the workpiece. The fixed base 1 is equipped with a position adjustment mechanism, a space adjustment mechanism, and a drive mechanism. The space adjustment mechanism includes multiple screw sleeves 5 installed at the bottom of multiple sliders 4 and screw rods 6 screwed into the multiple screw sleeves 5. The screw sleeves 5 are arranged along the height direction of the fixed base 1. The bottom ends of the multiple screw rods 6 are fixed to the top of the multiple pressure plates 2. The output end of the drive mechanism is connected to the multiple screw sleeves 5. The fixed base 1 has a cylindrical structure. Multiple sliding grooves 3 are evenly distributed around the circumference of the fixed base 1. The drive mechanism drives the multiple screw sleeves 5 to rotate synchronously, thereby driving the multiple screw rods 6 to move downward synchronously. The pressure plates 2 move downward accordingly, so that the space between the workpiece below the pressure plates 2 and the fixed base 1 can be adjusted, further facilitating different types of processing of the workpiece below the pressure plates 2.

[0028] Each of the multiple slide grooves 3 has a parallel limiting groove 7 on one side, which is connected to the slide groove 3. A limiting block 8 is fixed to the outer wall of the slider 4, and the limiting block 8 slides on the inner wall of the limiting groove 7. The position adjustment mechanism includes multiple slide grooves 3 that are radially opened inside the fixed base 1, multiple sliders 4 that are respectively installed inside the multiple slide grooves 3, and multiple displacement components for moving the multiple sliders 4 respectively. The displacement components include a lead screw 9 that is rotatably connected to the inner wall of the slide groove 3 along its length direction and a component fixed to the lead screw 9 along its length direction. A handle 10 extends to one end of the fixed base 1. A slider 4 is screwed to the outside of the lead screw 9. By rotating the lead screw 9 through the handle 10, the slider 4 moves along the inner wall of the slide groove 3. The limiting block 8 moves along the inner wall of the limiting groove 7. When the slider 4 moves, it drives the screw sleeve 5, the screw 6 and the pressure plate 2 to move synchronously. Thus, the position of the pressure plate 2 can be adjusted according to the size of the workpiece. In addition, multiple lead screws 9 can be adjusted separately, so the positions of the four pressure plates 2 can be adjusted individually, thus enabling the fixing of workpieces of different shapes.

[0029] A fixing bolt 11 is screwed into the inside of the handle 10 along the axial direction of the lead screw 9. The fixing bolt 11 passes through the handle 10, and one end of the fixing bolt 11 abuts against the outer wall of the fixed seat 1. When the operator needs to rotate the lead screw 9 through the handle 10, the fixing bolt 11 is first reversed to move it away from the fixed seat 1. After the fixing bolt 11 loses its fixing effect, the handle 10 can be rotated. When the lead screw 9 needs to be limited after rotation, the fixing bolt 11 is rotated forward to move it towards the fixed seat 1 until the fixing bolt 11 abuts against the outer wall of the fixed seat 1. This completes the limitation of the handle 10 and prevents the lead screw 9 from loosening.

[0030] A telescopic rod 12 parallel to the screw sleeve 5 is provided on one side. The fixed end of the telescopic rod 12 is fixedly connected to the bottom of the slider 4, and the extended end of the telescopic rod 12 is fixedly connected to the top of the pressure plate 2. When the pressure plate 2 moves, the telescopic rod 12 extends and retracts accordingly. The telescopic rod 12 is provided to ensure that the pressure plate 2 does not rotate, so that when the screw sleeve 5 is rotated, the screw 6 can move vertically normally.

[0031] The number of tablet press 2, slide groove 3, slider 4, displacement assembly and screw sleeve 5 are all four. The drive mechanism includes a motor 13 mounted on the top of the fixed base 1, four drive shafts 14 arranged radially inside the fixed base 1, four connecting sleeves 15 respectively mounted on the outside of the four drive shafts 14, a linkage component for driving the four drive shafts 14 to rotate, and four transmission components for driving the four screw sleeves 5 to rotate synchronously. The four drive shafts 14 are respectively arranged along the length direction of the four slide grooves 3, and the outside of each of the four drive shafts 14 is rotatably connected to a fixed component that is fixed to the bottom of the fixed base 1. Block 16, the linkage includes a first bevel gear 17 fixed to the output end of the motor 13 and four second bevel gears 18 respectively fixed to one end of the four transmission shafts 14 near the motor 13. The first bevel gear 17 meshes with the four second bevel gears 18 respectively. A key pin 19 is fixedly connected to the outer wall of the transmission shaft 14 along its axial direction. A keyway is opened on the inner wall of the connecting sleeve 15 along its axial direction. The key pin 19 slides in the inside of the keyway. The transmission component includes a connecting block 20 rotatably connected to the outside of the connecting sleeve 15 and two third bevel gears 21 respectively sleeved on the outside of the connecting sleeve 15 and the threaded sleeve 5. Block 20 has a U-shaped structure. Connecting block 20 is also rotatably connected to the outside of threaded sleeve 5. The top of connecting block 20 is fixedly connected to the bottom of slider 4. The starting motor 13 drives the first bevel gear 17 to rotate. The first bevel gear 17 meshes with four second bevel gears 18, respectively, driving the four drive shafts 14 to rotate. The key pins 19 on the outside of the drive shafts 14 connect to the keyways inside the connecting sleeves 15, respectively, driving the four connecting sleeves 15 to rotate. The third bevel gear 21 on the outside of the connecting sleeve 15 meshes with the third bevel gear 21 on the outside of the threaded sleeve 5, thus... Instead of driving the four screw sleeves 5 to rotate synchronously, the output of the control motor 13 is reversed, which can drive the four screw sleeves 5 to rotate synchronously in opposite directions. In addition, after the slider 4 moves, the connecting sleeve 15 moves synchronously through the connecting block 20. The keyway inside the connecting sleeve 15 slides along the outside of the key pin 19, so that the third bevel gear 21 outside the connecting sleeve 15 and the third bevel gear 21 outside the screw sleeve 5 always remain engaged. The transmission shaft 14 also always drives the connecting sleeve 15 to rotate. Furthermore, after the screw sleeve 5 moves, the drive mechanism can always drive the screw sleeve 5 to rotate normally.

[0032] Working principle: When the operator needs to adjust the space between the pressure plate 2 and the fixed seat 1, the motor 13 is started to drive the first bevel gear 17 to rotate. The first bevel gear 17 meshes with the four second bevel gears 18, which in turn drive the four transmission shafts 14 to rotate. The key pins 19 on the outside of the transmission shafts 14 are connected to the keyways inside the connecting sleeves 15, which in turn drive the four connecting sleeves 15 to rotate. The third bevel gear 21 on the outside of the connecting sleeves 15 meshes with the third bevel gear 21 on the outside of the screw sleeves 5, which in turn drive the four screw sleeves 5 to rotate synchronously. This, in turn, drives the multiple screws 6 to move downward synchronously. The pressure plate 2 moves downward accordingly, so that the space between the workpiece below the pressure plate 2 and the fixed seat 1 can be adjusted, which further facilitates the processing of different types of workpieces below the pressure plate 2.

[0033] When the operator needs to adjust the horizontal position of the pressure plate 2, the screw 9 is rotated by the handle 10, which drives the slider 4 to move along the inner wall of the slide groove 3. The limiting block 8 moves along the inner wall of the limiting groove 7. When the slider 4 moves, it drives the screw sleeve 5, the screw 6 and the pressure plate 2 to move synchronously. Thus, the position of the pressure plate 2 can be adjusted according to the size of the workpiece. In addition, multiple screws 9 can be adjusted separately, so the positions of the four pressure plates 2 can be adjusted individually, thus enabling the fixing of workpieces of different shapes.

[0034] It is worth mentioning that after the slider 4 moves, the connecting block 20 drives the connecting sleeve 15 to move synchronously. The keyway inside the connecting sleeve 15 slides along the outside of the key pin 19, so that the third bevel gear 21 outside the connecting sleeve 15 and the third bevel gear 21 outside the threaded sleeve 5 always remain engaged. The transmission shaft 14 also always drives the connecting sleeve 15 to rotate. Furthermore, after the threaded sleeve 5 moves, the drive mechanism can always drive the threaded sleeve 5 to rotate normally.

[0035] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
