DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the application clearer, the application is further described in detail below in combination with embodiments and drawings. Here, the illustrative embodiments of the application and their description serve to explain the application, but do not constitute a limitation on the application.

[0040] Reference is made to Figures 1 to 7 , for example Figure 1 , Figure 7 ​As shown, the product stable clamping mechanism of the tapping machine provided by the embodiment comprises a base plate 5 installed on the tapping machine table top 1, a limiting plate 6 installed on the base plate 5, and a clamping device. The clamping device comprises a fixed part 3 and a movable part 4. The housing 31 of the fixed part 3 is installed on the left side of the base plate 5, and can reliably limit the left end of the product 2 to be processed. The movable part 4 is arranged on the right side of the base plate 5, and can press against the right end of the product 2 to be processed. The limiting plate 6 is connected to the base plate 5 through two positioning pins 61, and is fixed to the base plate 5 through two inner hexagonal screws 62. The limiting plate 6 is used to limit the rear end of the product 2 to be processed. Through the limiting and clamping of the fixed part 3, the limiting plate 6 and the movable part 4, the product 2 to be processed is stably fixed to the base plate 5, so that the tapping machine can tap the product 2 to be processed.

[0041] In an embodiment, as shown in Figure 2 , Figure 3 The fixed part 3 further comprises a worm 33, a turbine 34, a connecting barrel 35, a connecting rod 36 and a piston block 37. The worm 33 is rotatably connected to the housing 31. Specifically, the lower end of the worm 33 is connected to a bearing seat on the bottom wall of the housing 31, and the upper end is connected to a bearing on the upper wall of the housing 31. The small shaft of the worm 33 extends out of the housing 31 upwardly, and an outer surface of the upper end of the small shaft is circumscribed by a hand wheel 32. The turbine 34 is rotatably arranged in the housing 31, and is in meshing transmission with the worm 33. The left barrel body 351 of the connecting barrel 35 is installed in the housing 31 through fixing screws on the flange 352, and the fixing screws are installed on the right end cover 311 of the housing 31. The piston block 37 is in sliding fit with the inner wall of the left barrel body 351. The left end of the connecting rod 36 is hinged to the turbine 34, and the right end is hinged to the piston block 37.

[0042] In an embodiment, as shown in Figure 3 , Figure 4 and Figure 5 The fixed part 3 further comprises a spiral compression spring 38 and a push rod 39. The push rod 39 extends through the right barrel body 353 of the connecting barrel 35 and extends into the left barrel body 351 until it is fixed to the right side end face of the piston block 37. The spiral compression spring 38 is accommodated in the left barrel body 351, and is sleeved on the outer periphery of the push rod 39. The right end of the spiral compression spring 38 is pressed against the right spring seat 355 of the right barrel body 353, and the left end is pressed against the left spring seat 371 of the piston block 37. The push rod 39 is in sliding fit with the right barrel body 353.

[0043] Preferably, the push rod 39 can be fixed to the right barrel body 353 through a square head long cylindrical end set screw 354.

[0044] In order to make the fixation of the push rod 39 and the right barrel body 353 more reliable, a square head long cylindrical end set screw 354 is arranged on the right barrel body 353.

[0045] Preferably, a fixed block 391 is mounted at the right end of the push rod 39, and a pair of rubber blocks 3911 is connected to the fixed block 391 to avoid hurting the product 2 to be processed.

[0046] In an embodiment, as shown in Figure 3 and Figure 4 , a pair of long grooves 392 is symmetrically formed on the outer periphery of the push rod 39, and a square head long cylindrical end fixing screw 354 is screwed on the right cylinder body 353, the long cylindrical end of the square head long cylindrical end fixing screw 354 can extend into the long groove 392 and abut against the inner bottom wall of the long groove 392, so that the push rod 39 is reliably fixed on the right cylinder body 353, and the position of the fixed block 391 on the base plate 5 is determined, thereby meeting the positioning of products 2 of different sizes.

[0047] As shown in Figure 1 , Figure 2 and Figure 7 , if the position of the fixed block 391 on the base plate 5 needs to be adjusted, first loosen the square head long cylindrical end fixing screw 354 to unlock the push rod 39 from the right cylinder body 353, then rotate the hand wheel 32 to drive the worm 33 to rotate, the worm 33 drives the worm wheel 34 to rotate, the connecting rod 36 on the worm wheel 34 moves, driving the piston block 37 to move in the left cylinder body 351, thereby driving the push rod 39 to move relative to the right cylinder body 353, after adjusting the position of the fixed block 391 on the base plate 5, tighten the square head long cylindrical end fixing screw 354 to lock the push rod 39 with the right cylinder body 353, then place the product 2 to be processed on the base plate 5, the left end surface of the product 2 to be processed abuts against the right end surface of the fixed block 391, and the rear end surface of the product 2 to be processed abuts against the front end surface of the limiting plate 6, thereby realizing the positioning of the product 2 to be processed, and then starting the movable part 4 to complete the clamping of the product 2 to be processed.

[0048] In an embodiment, as shown in Figure 1 , Figure 6 and Figure 7 , the movable part 4 includes a fixed table 42 mounted on the base plate 5, a gas cylinder 41 mounted on the fixed table 42, and a pressure head 44 mounted on the piston rod 43 of the gas cylinder 41.

[0049] Preferably, a rubber gasket 45 is connected to the pressure head 44.

[0050] Working process: before tapping, first place the product 2 to be processed on the base plate 5, the left end face of the product 2 to be processed abuts against the right end face of the fixed block 391, the rear end face of the product 2 to be processed abuts against the front end face of the limiting plate 6, that is, the product 2 to be processed is positioned, then start the air cylinder 41, so that the air cylinder 41 drives the piston rod 43 to move horizontally, drives the pressing head 44 to move, so that the pressing head 44 gradually abuts against the right side of the product 2 to be processed, effectively clamping the two ends of the product.

[0051] The rubber block 3911 on the fixed block 391 and the rubber gasket 45 on the pressing head 44 can ensure effective protection of the outer end of the product during clamping, and the product will not be damaged due to clamping force.

[0052] If the products 2 to be processed with different widths are tapped, the position of the limiting plate 6 in the width direction of the base plate 5 can be adjusted (a plurality of rows of pin holes for connecting the positioning pins 61 and screw holes for connecting the inner hexagonal screws 62 are arranged on the base plate 5 in the width direction) to meet the clamping of products with different widths.

[0053] For the products 2 to be processed with different lengths, the position of the push rod 39 relative to the right cylinder 353 needs to be adjusted to meet the clamping of products with different lengths.

[0054] As described above, the limiting plate 6 and the clamping device provided in the present application can clamp the two ends of the product 2 to be processed, and the work efficiency is greatly improved compared with the vise clamping, which can ensure the processing quality of the product.

[0055] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the embodiments of the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
