[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] See also Figures 1 to 3 The present application provides a technical solution: a grinding device, comprising a base 1, a support block 2 is fixedly installed on the top of the base 1, a support frame 3 is fixedly installed on the top of the base 1, a limiting rotation component 500 for limiting the steel pipe is installed between the top of the support block 2 and the inner side of the support frame 3, and a grinding component 600 for grinding the steel pipe is installed on the top of the base 1; through the coordinated use of the limiting rotation component 500 and the grinding component 600 on the top of the base 1, it can be applied to the end grinding work of steel pipes of various specifications, so that steel pipes of different specifications and models can all be effectively ground at the end, thereby facilitating the subsequent welding of the steel pipe, and improving the application scope of the grinding device, effectively improving the practicability of the grinding device, and facilitating the operator to use.

[0030] In this embodiment, the position limiting rotation assembly 500 is a structure used to limit the position of the steel pipe and enable it to rotate.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the limiting rotation assembly 500 includes a trapezoidal groove 501 opened on the top of the support block 2, four fixed plates 502 fixed on the inner side of the trapezoidal groove 501, a rotating rod 503 rotatably connected between the opposite sides of the two corresponding fixed plates 502 through a bearing, a rubber roller 504 fixed to the outer side of the rotating rod 503, a driving mechanism 505 fixedly installed on the outer side of one of the fixed plates 502, an arch block 506 located on the inner side of the support frame 3, four connecting plates 507 fixed on the inner side of the arch block 506, a round rod 508 rotatably connected between the opposite sides of the two corresponding connecting plates 507 through a bearing, and an abutment roller 509 fixed to the outer side of the round rod 508.

[0032] It should be noted that a screw rod 401 is penetrated and threadedly connected at the top of the support frame 3, a light rod 402 is fixed to the top of the arch block 506, and a linear bearing 403 penetrated by the light rod 402 is fixed to the top of the support frame 3. The support frame 3 includes two vertical plates and a horizontal plate fixed between the tops of the two vertical plates. The support frame 3 is located on the outside of the support block 2, and a handle is fixedly installed at the top of the screw rod 401. The bottom end of the screw rod 401 penetrates the top of the support frame 3 and is rotatably connected to the top of the arch block 506 through a bearing. The top of the light rod 402 sequentially penetrates the top of the support frame 3 and the inner side of the linear bearing 403, so that when the screw rod 401 rotates, the arch block 506 can be driven to adjust its height through the limiting cooperation between the light rod 402 and the linear bearing 403.

[0033] In addition, both sides of the trapezoidal groove 501 are open, so that the steel pipe can be inserted normally. The output shaft of the driving mechanism 505 passes through the outer side of the corresponding fixed plate 502 and is fixedly connected to the end of the corresponding rotating rod 503, so that the driving mechanism 505 can drive the corresponding rotating rod 503 to rotate. The driving mechanism 505 can be a servo motor.

[0034] At the same time, both sides of the arch block 506 are opened, and the arch block 506 can be moved to the inside of the trapezoidal groove 501, so that the arch block 506 can be adjusted in height and can also abut and limit the steel pipe through the abutment roller 509.

[0035] In this embodiment, the grinding assembly 600 is a structure for grinding the end and outer side of the steel pipe.

[0036] like Figure 1 As shown, the grinding assembly 600 includes a column 601 fixed to the top of the base 1, a top plate 602 fixed to the top of the column 601, a first electric push rod 603 passing through and fixedly installed on the top of the top plate 602, a first grinder 604 fixedly installed on the output shaft of the first electric push rod 603, a second electric push rod 605 fixedly installed on the top of the base 1, and a second grinder 606 fixedly installed on the output shaft of the second electric push rod 605.

[0037] It should be noted that the first grinder 604 includes a first installation box fixedly installed on the output shaft of the first electric push rod 603, a first drive motor fixedly installed on the inner side of the first installation box and the output shaft passes through the outer side of the first installation box, and a first grinding block fixedly installed on the output shaft of the first drive motor; the second grinder 606 includes a second installation box fixedly installed on the output shaft of the second electric push rod 605, a second drive motor fixedly installed on the inner side of the second installation box and the output shaft passes through the outer side of the second installation box, and a second grinding block fixedly installed on the output shaft of the second drive motor. The first grinding block can be abutted against the end of the steel pipe, and the second grinding block can be fitted against the outer side of the steel pipe, so that the first grinder 604 and the second grinder 606 can respectively grind the end and outer surface of the steel pipe.

[0038] The working principle of the above embodiment is:

[0039] When grinding the steel pipe, the steel pipe is placed on the inner side of the trapezoidal groove 501, and the first electric push rod 603 and the second electric push rod 605 are started, which can change the position of the first grinder 604 and the second grinder 606, and make the outer side of the steel pipe abut against the outer sides of the two rubber rollers 504, move the steel pipe so that its end abuts against the grinding surface of the first grinder 604, rotate the screw rod 401, and under the limiting cooperation between the light rod 402 and the linear bearing 403, the arch block 506 moves to the side close to the steel pipe, and make the outer sides of the two abutting rollers 509 abut against the outer side of the steel pipe. At this time, the limiting work of the steel pipe is completed, the first grinder 604 and the second grinder 606 are started, and the driving mechanism 505 is started to drive the corresponding rotating rod 503 to rotate, so that the rubber roller 504 rotates, and the steel pipe is rotated under the support of the other rubber roller 504, so that it can grind the end of the steel pipe normally.

[0040] Compared with the prior art, the grinding device, through the coordinated use of the limiting rotating assembly 500 and the grinding assembly 600 on the top of the base 1, can be applied to the end grinding of steel pipes of various different specifications, so that steel pipes of different specifications and models can all be effectively end-grinded, thereby facilitating the subsequent welding of the steel pipes, and improving the application scope of the grinding device, effectively improving the practicability of the grinding device, and being easy for the operator to use, solving the problem that the existing steel pipe grinding device can only be applied to the grinding of steel pipes of one specification during use, resulting in a narrow scope of application.
