The clamping block is L-shaped and includes the mounting part and a clamping column perpendicular to the mounting part. The top of the clamping column clamps the workpiece toward the positioning pin. The positioning pin is fixed to the end face of the extended end of the positioning member. The positioning member is fixed to the upper side of the cantilever. The limiting structure includes a first limiting structure and a second limiting structure. The first limiting structure is located on one side of the fixing frame, and the second limiting structure is located on the other side of the fixing frame. The proximity switch is fixed to one side of the clamping arm, and its sensing end corresponds to the flange positioning surface of the workpiece.

[0005] Preferably, the first limiting structure includes an L-shaped mounting component and a first limiting component. The L-shaped mounting component includes a first mounting strip fixed to one side of the upright plate and a second mounting strip horizontally arranged perpendicular to the upright plate. The first limiting component is fixed in front of the second mounting strip and has a forward-extending inclined end. The front end of the inclined end is a positioning inclined surface corresponding to the first curved surface of the workpiece.

[0006] Preferably, the mounting base plate has a forward extension on the side opposite to the first limiting structure. The second limiting structure includes a square frame mounting member fixed to the outside of the forward extension and a second limiting member. The square frame mounting member is perpendicular to the mounting base plate. The second limiting member includes a mounting section fixed to the bottom of the square frame mounting member, an inclined extension section extending outward and forward from the mounting section, and a limiting section located at the front end of the inclined extension section. The inner side of the limiting section is a positioning surface two corresponding to the second curved surface of the workpiece.

[0007] Preferably, the end of the positioning pin connected to the positioning member has an annular clamping plate, and the top of the clamping column of the clamping block has a U-shaped structure. The groove in the center of the U-shaped structure corresponds to the protruding end of the positioning pin, and the protruding end of the U-shaped structure presses the workpiece onto the annular clamping plate.

[0008] Preferably, the clamping cylinder seat is a frame structure perpendicular to the upright plate. A U-shaped groove plate is vertically fixed on one side of the clamping cylinder seat near the clamping arm, and the clamping cylinder is fixed on the other side. The piston rod of the clamping cylinder extends out from the U-shaped groove of the U-shaped groove plate.

[0009] Preferably, an L-shaped plate is fixed to the side of the clamping arm. The L-shaped plate has a connecting plate fixed to the side of the clamping arm and a flat plate perpendicular to the side of the clamping arm. The connecting plate is provided with a waist-shaped hole for installing a fixing bolt. The waist-shaped hole is set in a direction perpendicular to the flat plate. The proximity switch is fixed on the flat plate.

[0010] Preferably, the sliding mechanism includes a pair of slide rails fixed on the worktable, a pair of sliding connectors that slide with the slide rails, and a sliding cylinder. The sliding connectors are all fixed to the mounting base plate. L-shaped connecting rods are symmetrically fixed on both sides of the sliding cylinder.

[0012] Preferably, an adjusting shim is provided between the positioning member and the cantilever portion, and an adjusting shim is provided between the mounting portion and the L-shaped connecting arm.

[0013] The present invention has the following advantages:

[0014] 1. After the workpiece is positioned by the positioning component and the limiting structure, it is clamped by the clamping cylinder. At the same time, the distance between the workpiece and the flange positioning surface can be determined by the proximity switch to see if it meets the requirements. If it meets the requirements, it means that the flange positioning surface is in the correct position after clamping the workpiece. A switch signal can be sent to proceed to the next welding process. The proximity switch can be used for automatic control and can also be used to send prompt signals to help the operator understand the situation.

[0015] 2. The bottom of the positioning component is equipped with an adjusting shim. During installation and adjustment, the adjusting shim can be added or removed to adjust the position of the positioning component. The positioning pin cooperates with the positioning hole to adjust the Z-axis height of the workpiece after clamping.

[0016] 3. The distance between the clamping block and the adjusting shim can be adjusted by adjusting the number of shims. This ensures that the clamping block can clamp the workpiece and also increases or decreases the clamping force.

[0017] 4. For workpieces with complex shapes, after clamping, this mechanism can quickly determine whether the workpiece is accurately clamped to the predetermined position, saving the time cost of manual judgment and improving efficiency. For the reinforced plate structure actually used, the first and second limiting structures can respectively ensure the overall initial positioning of the workpiece. Attached Figure Description

[0025] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.

[0026] Example 1:

[0027] like Figure 1 , 3 As shown in Figure 6, this embodiment of the present invention provides an operation method for a reinforcing plate positioning and clamping mechanism, including a sliding mechanism slidably mounted on a workbench, a mounting base plate 1 fixed below the sliding end of the sliding mechanism, a limiting structure, a fixing frame 2, a clamping cylinder 3, a clamping arm 5, a clamping block 6, a positioning component 7, a positioning pin 8, and a proximity switch 9.

[0028] The mounting bracket 2 is fixed to the bottom of the mounting base plate 1. A mounting bracket mounting member 26 is fixed to the bottom of the mounting base plate 1. The mounting bracket mounting member 26 is L-shaped, with the mounting bracket 2 installed on its inner side. The mounting bracket 2 includes a vertical plate 201 and a rectangular mounting plate 203 perpendicular to the vertical plate 201. A triangular rib 204 connects the rectangular mounting plate 203 to the vertical plate 201. The vertical plate 201 also has a forward-extending cantilever portion 202. Each of the two perpendicular connecting portions of the mounting bracket mounting member 26 has a slotted hole 205. The side of the rectangular mounting plate 203 has threaded holes corresponding to the two slotted holes 205. Adjusting shims 27 are provided between the mounting bracket mounting member 26 and the mounting bracket 2. Screws are used to connect and fix the mounting bracket 2 to the threaded holes through the slotted holes 205. The number and thickness of the adjusting shims 27 can adjust the position of the mounting bracket 2, and the slotted holes 205 also facilitate fixing the mounting bracket 2 after position adjustment.

[0029] The clamping cylinder seat 4 is hinged to the lower end of the vertical plate 201 via a horizontal hinge shaft perpendicular to the vertical plate 201. The overhang 202 is located in front of the clamping cylinder seat 4 and connected to the clamping arm 5. The clamping cylinder seat 4 is a frame structure perpendicular to the vertical plate 201. A U-shaped groove plate 15 is vertically fixed to the side of the clamping cylinder seat 4 near the clamping arm 5, and the clamping cylinder 3 is fixed to the other side. The piston rod of the clamping cylinder 3 extends out from the U-shaped groove of the U-shaped groove plate 15. The front end of the U-shaped groove plate 15 can limit the contact of the clamping arm 5 and provide a certain degree of protection for the piston rod of the clamping cylinder 3.

[0030] The clamping arm 5 includes a rearwardly extending connecting end 501, an upwardly extending hinge seat 502, and a forwardly extending L-shaped connecting arm 503. The connecting end 501 is hinged to the telescopic end of the clamping cylinder 3, and the hinge seat 502 is hinged to the end of the cantilever portion 202. The mounting portion 601 of the clamping block 6 is fixed to the inner side of the extended portion of the L-shaped connecting arm 503. An adjusting shim 27 is provided between the mounting portion 601 and the L-shaped connecting arm 503. By adjusting the number of shims 27, the distance from the clamping block 6 to the adjusting shims 27 can be adjusted, thus ensuring that the clamping block 6 can clamp the workpiece and also increasing or decreasing the clamping force.

[0031] The clamping block 6 is L-shaped, including the mounting part 601 and a clamping post 602 perpendicular to the mounting part 601. The top of the clamping post 602 clamps the workpiece towards the positioning pin 8. The positioning element 7 is fixed to the upper side of the overhanging part 202, and the positioning pin 8 is fixed to the end face of the protruding end of the positioning element 7. The bottom of the positioning element 7 is provided with an adjusting shim 27. During installation and adjustment, the position of the positioning element 7 can be adjusted by adding or removing the adjusting shim 27. The positioning pin 8 cooperates with the positioning hole 22 to adjust the Z-axis height of the workpiece after clamping. The end of the positioning pin 8 connected to the positioning element 7 has an annular clamping plate. The top of the clamping post 602 of the clamping block 6 has a U-shaped structure 603. The groove in the center of the U-shaped structure 603 corresponds to the protruding end of the positioning pin 8. The protruding end of the U-shaped structure 603 presses the workpiece against the annular clamping plate.

[0032] The proximity switch 9 is fixed to one side of the clamping arm 5, and its sensing end corresponds to the flange positioning surface 23 of the workpiece. An L-shaped plate 10 is fixed to the side of the clamping arm 5. The L-shaped plate 10 has a connecting plate 21 fixed to the side of the clamping arm 5 and a flat plate perpendicular to the side of the clamping arm 5. The connecting plate 21 has a slotted hole for mounting fixing bolts, and the slotted hole is positioned perpendicular to the flat plate. The proximity switch 9 is fixed on the flat plate. The position of the proximity switch 9 can be adjusted according to processing requirements through the slotted hole to ensure accurate positioning and easy adjustment. The proximity switch 9 is connected to the automatic control system via a circuit, outputting a switching signal to the system.

[0033] The limiting structure includes a first limiting structure and a second limiting structure. The first limiting structure is located on one side of the fixing frame 2, and the second limiting structure is located on the other side of the fixing frame 2. The first limiting structure includes an L-shaped mounting member 11 and a first limiting member 12. The L-shaped mounting member 11 includes a first mounting strip 111 fixed to one side of the upright plate 201 and a second mounting strip 112 horizontally arranged perpendicular to the upright plate 201. The first limiting member 12 is fixed in front of the second mounting strip 112 and has a forward-extending inclined end 121. The front end of the inclined end 121 is a positioning inclined surface corresponding to the first curved surface of the workpiece. The mounting base plate 1 has a forward extension 101 on the side opposite to the first limiting structure. The second limiting structure includes a square frame mounting member 13 fixed to the outside of the forward extension 101 and a second limiting member 14. The square frame mounting member 13 is perpendicular to the mounting base plate 1. The second limiting member 14 includes a mounting section 141 fixed to the bottom of the square frame mounting member 13, an inclined extension section 142 extending outward and forward from the mounting section 141, and a limiting section 143 located at the front end of the inclined extension section 142. The inner side of the limiting section 143 is a positioning surface two corresponding to the second curved surface of the workpiece.

[0034] The sliding mechanism includes a pair of slide rails 17 fixed to the worktable, a pair of sliding connectors 18 that slide with the slide rails 17, and a sliding cylinder 16. The sliding connectors 18, which are the sliding ends of the sliding mechanism, are all fixed to the mounting base plate 1. L-shaped connecting rods 20 are symmetrically fixed on both sides of the sliding cylinder 16. The bottom of each L-shaped connecting rod 20 is fixed to the worktable. The piston rod of the sliding cylinder 16 extends to a connecting rod 19, the lower end of which is fixed to a connecting plate 21. The connecting plate 21 is fixed to the mounting base plate 1 and located between the sliding connectors 18. This mechanism allows adjustment of the position of the lower clamping part for convenient subsequent operations.

[0035] The operation of this clamping mechanism is as follows: First, before use, adjust each part of the mechanism to a suitable position through testing. In actual use, the sliding mechanism first moves the clamping part to a suitable position for clamping the workpiece. Then, the reinforcing plate, which is the workpiece to be processed, is installed on the positioning pin 8 through the positioning hole 22, and the first curved part 24 and the second curved part 25 of the reinforcing plate are positioned by the limiting structure respectively. At this time, the flanged positioning surface 23 faces downward. The clamping cylinder 3 is started, and the clamping cylinder 3 pushes the clamping arm 5 to rotate, which in turn drives the clamping block 6 to rotate, pressing the area around the positioning hole 22 onto the annular clamping plate to achieve clamping of the reinforcing plate. At this time, the proximity switch 9 approaches the flanged positioning surface 23. If the distance meets the requirements, the proximity switch 9 sends a switch signal to the automatic control system, thereby starting the next processing step, such as welding the clamped reinforcing plate. If the distance does not meet the requirements, no signal is sent, the next step will not run, and the operator will check to determine whether the clamping mechanism needs adjustment or the reinforcing plate is not up to standard. After processing, the clamping cylinder 3 runs in reverse, and after the clamping block 6 is reset, the operator removes the processed clamping plate 1.
