[0002] Welding technology is widely used in fields such as machinery and electronics. It is a processing technique that joins metal parts by heating, high temperature, or high pressure. After welding, weld seams are formed. Weld seams have a certain impact on the overall aesthetics of the welded parts, and for some special welded parts, there are also corresponding specification range requirements for the weld seam reinforcement. Therefore, it is necessary to treat the weld seams on the metal end faces using weld seam surface treatment equipment.

[0003] Some metal end-face weld surface treatment devices have grinding blocks that are not easy to disassemble and maintain. Long-term use may cause the surface of the grinding blocks to deform or break, thus affecting the grinding accuracy. Therefore, they do not meet the existing requirements. In response, we have proposed a metal end-face weld surface treatment device. Utility Model Content

[0004] The purpose of this utility model is to provide a surface treatment device for metal end face welds, so as to solve the problem mentioned in the background art that the grinding block in the existing surface treatment device for metal end face welds is not easy to disassemble and maintain, and long-term use may cause the surface of the grinding block to be deformed or damaged, thereby affecting the grinding accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for metal end face welds, comprising a support frame, a drive seat connected to the lower part of the support frame via a cylinder, a movable seat movably provided at the bottom end of the drive seat, a second motor fixedly provided at the upper end of the movable seat near the front side, the output end of the second motor extending through a coupling to the bottom end of the movable seat and fixedly connected to a connecting seat, an installation groove provided at the bottom end of the connecting seat, a mounting seat detachably connected inside the installation groove, the bottom end of the mounting seat extending to the outer side of the bottom end of the connecting seat and fixedly connected to a grinding block.

[0006] Preferably, a fixing plate is fixedly connected to both sides of the bottom end of the drive seat, and a threaded rod is connected between the two fixing plates by a first motor. A sliding groove is provided above the threaded rod and at the bottom end of the drive seat. The rear side of the movable seat is threadedly connected to the outer surface of the threaded rod, and the upper end is slidably connected to the inside of the sliding groove.

[0007] Preferably, the inner wall of the mounting groove is provided with slots on both the front and rear sides, and the outer surface of the mounting base is fixedly connected with blocks that slide and engage with the slots on both the front and rear sides.

[0008] Preferably, a drive groove is provided on both the left and right sides of the mounting groove and at the bottom of the connecting seat. An internal threaded sleeve is fixedly connected to the bottom of the drive groove on both sides. A semi-threaded rod with threads passing through the internal threaded sleeve and extending into the drive groove is provided on both sides of the bottom of the connecting seat. An arc groove is provided on the outer surface of the semi-threaded rod near the upper end.

[0009] Preferably, each of the two drive slots has a movable cavity on one side close to each other and inside the connecting seat. A drive rod is movably installed inside each of the two movable cavities. A limit block is fixedly connected to the end of the drive rod away from the drive slot. A spring is fixedly connected between one side of the limit block and one side of the inner wall of the movable cavity, and the spring is wound around the outer surface of the drive rod.

[0010] Preferably, the end of the drive rod away from the limiting block extends movably through the interior of the drive groove and engages movably with the arc groove.

[0011] Preferably, the end of the limiting block away from the drive rod extends movably through the interior of the mounting groove, and limiting grooves corresponding to the movable cavity are provided on both the left and right sides of the outer surface of the mounting base. The end of the limiting block extending through the interior of the mounting groove is inserted into the corresponding limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model places the metal end face weld seam below the support frame, then starts the cylinder to drive the drive seat with grinding block to move towards the metal end face weld seam, and at the same time the second motor drives the grinding block to rotate, thereby grinding the weld seam. In addition, by starting the first motor to drive the threaded rod to rotate, when the threaded rod rotates, the thread drives the movable seat with grinding block to move left and right under the limit of the slide groove, so that the position of the grinding block can be adjusted according to the length of the metal end face weld seam for grinding treatment.

[0014] 2. This utility model rotates the semi-threaded rod, causing the semi-threaded rod to rotate within the internal threaded sleeve and move away from the inside of the drive groove. When the arc groove on the outer surface of the semi-threaded rod aligns with the movable cavity, the spring inside the movable cavity releases its elastic force, and one end of the drive rod engages inside the arc groove. This causes the limiting block to disengage from the limiting groove and move back into the movable cavity, thereby releasing the limiting effect on the mounting seat. The mounting seat can then be removed from the inside of the mounting groove for maintenance or replacement of the grinding block. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 An embodiment of this utility model provides a surface treatment device for metal end face welds, including a support frame 1. A drive seat 3 is driven and connected to the lower part of the support frame 1 via a cylinder 2. A movable seat 7 is movably provided at the bottom end of the drive seat 3. A second motor 8 is fixedly provided at the upper end of the movable seat 7 near the front side. The output end of the second motor 8 extends through a coupling to the bottom end of the movable seat 7 and is fixedly connected to a connecting seat 9. An installation groove 901 is opened at the bottom end of the connecting seat 9. An installation seat 11 is detachably connected inside the installation groove 901. The bottom end of the installation seat 11 extends to the outer side of the bottom end of the connecting seat 9 and is fixedly connected to a grinding block 10.

[0022] Fixed plates 4 are fixedly connected to both sides of the bottom end of the drive base 3. A threaded rod 6 is connected between the two fixed plates 4 by a first motor 5. A sliding groove 301 is provided above the threaded rod 6 and at the bottom end of the drive base 3. The rear side of the movable seat 7 is threadedly connected to the outer surface of the threaded rod 6, and the upper end is slidably connected to the inside of the sliding groove 301. By starting the first motor 5, the threaded rod 6 is driven to rotate. When the threaded rod 6 rotates, the threaded rod drives the movable seat 7, which is equipped with a grinding block 10, to move left and right under the limit of the sliding groove 301. Thus, the position of the grinding block 10 can be adjusted according to the length of the weld seam on the metal end face for grinding.

[0023] The mounting groove 901 has slots 902 on both the front and back sides of its inner wall. The mounting base 11 has a locking block 12 fixedly connected to both the front and back sides of its outer surface, which slides and engages with the slots 902. By inserting the mounting base 11 at the upper end of the grinding block 10 into the mounting groove 901 and making the locking block 12 on the outer surface of the mounting base 11 slide and engage with the slots 902 on the inner wall of the mounting groove 901, the limiting grooves 1101 on both sides of the mounting base 11 correspond to the movable cavity 904.

[0024] On both sides of the mounting groove 901, and at the bottom of the connecting seat 9, there are drive grooves 903. The bottom of each drive groove 903 is fixedly connected to an internal threaded sleeve 13. On both sides of the bottom of the connecting seat 9, there are semi-threaded rods 14 that thread through the internal threaded sleeves 13 and extend into the drive groove 903. The outer surface of the semi-threaded rod 14 near its upper end has an arc groove 1401. On the side of the two drive grooves 903 that are close to each other, and inside the connecting seat 9, there are movable cavities 904. Drive rods 15 are movably mounted inside both movable cavities 904, moving away from the drive grooves 901. One end of 03 is fixedly connected to a limiting block 16. A spring 17 is fixedly connected between one side of the limiting block 16 and one side of the inner wall of the movable cavity 904. The spring 17 is wrapped around the outer surface of the drive rod 15. The end of the drive rod 15 away from the limiting block 16 extends movably through the drive groove 903 and is movably engaged with the arc groove 1401. By rotating the semi-threaded rods 14 on both sides, the threads rotate on the inner threaded sleeve 13, causing the semi-threaded rods 14 to move towards the upper end of the drive groove 903, thereby causing one end of the drive rod 15 to disengage from the arc groove 1401 and contact the outer surface of the semi-threaded rods 14.

[0025] The end of the limiting block 16 away from the drive rod 15 extends movably through the interior of the mounting groove 901. Limiting grooves 1101 corresponding to the movable cavity 904 are provided on both the left and right sides of the outer surface of the mounting base 11. The end of the limiting block 16 extending through the interior of the mounting groove 901 is inserted into the corresponding limiting groove 1101. By having one end of the drive rod 15 contact the outer surface of the semi-threaded rod 14, the spring 17 inside the movable cavity 904 is pulled up, and the limiting block 16 at the other end of the drive rod 15 extends through the inner wall of the mounting groove 901 and is inserted into the corresponding limiting groove 1101, thereby fixing the grinding block 10 in place.

[0026] When using the metal end face weld surface treatment device, the metal end face weld is placed under the support frame 1, and then the cylinder 2 is started to drive the drive seat 3 with the grinding block 10 to move closer to the metal end face weld. At the same time, the second motor 8 drives the grinding block 10 to rotate, thereby grinding the weld. The first motor 5 is started to drive the threaded rod 6 to rotate. When the threaded rod 6 rotates, the thread drives the movable seat 7 with the grinding block 10 to move left and right under the limit of the slide groove 301. Thus, the position of the grinding block 10 can be adjusted according to the length of the metal end face weld for grinding treatment.

[0027] After prolonged use, the grinding block 10 can be rotated by rotating the semi-threaded rod 14, causing the semi-threaded rod 14 to rotate into the inner threaded sleeve 13 and move away from the inside of the drive groove 903. When the arc groove 1401 on the outer surface of the semi-threaded rod 14 aligns with the movable cavity 904, the spring 17 inside the movable cavity 904 releases its elastic force. One end of the drive rod 15 engages inside the arc groove 1401, thereby causing the limiting block 16 to disengage from the limiting groove 1101 and move into the movable cavity 904, thus releasing the limitation on the mounting base 11. The mounting base 11 can then be removed from the inside of the mounting groove 901 for maintenance or replacement of the grinding block 10. When installation is required, the mounting base 11 at the upper end of the grinding block 10 can be removed. The mounting base 11 is inserted into the mounting groove 901, and the locking block 12 on the outer surface of the mounting base 11 slides into the locking groove 902 on the inner wall of the mounting groove 901, so that the limiting grooves 1101 on both sides of the mounting base 11 correspond to the movable cavity 904. Then, the semi-threaded rods 14 on both sides are rotated to rotate into the internal thread sleeve 13, so that the semi-threaded rods 14 move towards the upper end of the drive groove 903, thereby causing one end of the drive rod 15 to disengage from the arc groove 1401 and contact the outer surface of the semi-threaded rod 14. Then, the spring 17 inside the movable cavity 904 is pulled up, and the limiting block 16 at the other end of the drive rod 15 extends through to the inner wall of the mounting groove 901 and is inserted into the corresponding limiting groove 1101, thereby fixing the grinding block 10 in place.
