[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figure 1 —5, a pipe joint sealing device, including a drill press body 1, a spindle 2 is provided on the drill press body 1, and further includes a clamping mechanism 3, a lifting drive unit 4 provided on the drill press body 1, and a sealing head 5. The output end of the lifting drive unit 4 is in transmission connection with the spindle 2. The sealing head 5 includes a mounting block 51, a sealing edge block 52, a connecting shaft 53, and a locking shaft 54. Rotating grooves 55 are symmetrically formed on the outer wall of one side of the mounting block 51. The sealing edge block 52 is rotatably connected to the rotating grooves 55 through the connecting shaft 53, and the connecting shaft 53 is fixedly connected to the inside of the mounting block 51 through the locking shaft 54;

[0026] The workpiece is clamped by the clamping mechanism 3, the sealing head 5 is driven to rotate by the spindle 2, and the sealing head 5 is driven to descend by the lifting drive unit 4. The sealing edge block 52 abuts against the workpiece and causes the edge of the workpiece to deform.

[0027] Specifically, the drill press body 1 is a conventional manual lifting drill press in the prior art, which has a driving mechanism for driving the spindle 2 to rotate. The driving mechanism inside the drill press body 1, as well as the connection relationship, principle, and structure with the spindle 2, are all prior art and will not be elaborated here.

[0028] A clamping mechanism 3 is provided on the drill press body 1. Through the clamping mechanism 3, the workpiece to be processed can be clamped. An elevating drive unit 4 is provided at the top of the drill press body 1. The output end of the elevating drive unit 4 is in transmission connection with the spindle 2, and the spindle 2 can be driven to move up and down by the elevating drive unit 4. The sealing head 5 is connected to one end of the spindle 2 away from the elevating drive unit 4. Specifically, the clamping structure of the cutting tool of the drill press body 1 in the prior art is adopted between the sealing head 5 and the spindle 2, which will not be elaborated here.

[0029] Specifically, the sealing head 5 includes a mounting block 51, a sealing edge block 52, a connecting shaft 53, and a locking shaft 54. Rotating grooves 55 are symmetrically formed on the outer wall of one side of the mounting block 51. A positioning hole is formed on the side wall of the mounting block 51, which penetrates the mounting block 51 and is connected to the rotating groove 55. Therefore, the sealing edge block 52 can be connected to the two rotating grooves 55 through the connecting shaft 53. A locking hole is formed on the outer wall of one side of the mounting block 51, which is connected to the positioning hole and has a "T" - shaped structure with the positioning hole. The locking shaft 54 is inserted into the locking hole, and the end of the locking shaft 54 is thread - connected to the connecting shaft 53. Since the connecting shaft 53 is fixedly connected inside the mounting block 51, the sealing edge block 52 is rotatably connected to the connecting shaft 53 and is located inside the rotating groove 55. Preferably, the number of the sealing edge blocks 52 is two, and the two sealing edge blocks 52 are respectively located inside the two rotating grooves 55.

[0030] In this utility model, the clamping mechanism 3 can clamp the workpiece to be processed. The drill press body 1 can drive the spindle 2 to rotate. The elevating drive unit 4, which is in transmission connection with the spindle 2, drives the sealing head 5 to descend. The sealing edge block 52 installed inside the mounting block 51 abuts against the edge of the workpiece. Since the sealing head 5 is driven to rotate by the spindle 2, during the rotation of the sealing edge block 52 along with the mounting block 51, the edge of the workpiece can be extruded, and the edge of the workpiece is driven to deform inward, so that the internal parts can be fixed at the end of the workpiece. The function of automatic - feeding rotary extrusion sealing can be realized, which can achieve high - efficiency processing of the edge sealing of the workpiece end, ensure the processing quality and processing accuracy, with high processing efficiency, and the workpiece spinning can be completed in one clamping.

[0031] As an embodiment provided by this utility model, such as Figure 4 and Figure 2As shown in the figure, the edge sealing block 52 includes an upper convex platform 521 and a lower convex platform 522. The upper convex platform 521 and the lower convex platform 522 are of an integral structure. An arc edge 523 is provided at the edge of the upper convex platform 521 and the lower convex platform 522. The top of the lower convex platform 522 is of a planar structure. The planar structure of the top surface of the lower convex platform 522 abuts against the outer wall of the circumferential direction of the workpiece. During the downward movement of the mounting block 51, the arc edge 523 contacts and abuts against the outer wall of the end of the workpiece. Since the arc edge 523 is in an arc shape, under the drive of the lifting drive unit 4, the edge of the end of the workpiece can be driven to deform along the arc edge 523 and bend inward to form a stepped structure, so as to limit the parts inside the end of the workpiece and prevent the parts from coming out.

[0032] As a further embodiment provided by the present utility model, specifically, as Figure 3 shown in the figure, the clamping mechanism 3 includes a fixing plate 31, a fixed seat 32, a sliding seat 33 and a transverse movement drive unit 34. The fixing plate 31 is fixedly connected to the drill press body 1 by bolts. The fixed seat 32 is fixedly installed on the outer wall of one side of the fixing plate 31. A slide rail is fixedly provided on the fixing plate 31. The sliding seat 33 is slidably connected to the slide rail. The transverse movement drive unit 34 is fixedly installed on the outer wall of the fixing plate 31, and the output end of the transverse movement drive unit 34 is connected to the sliding seat 33. The sliding seat 33 can be driven by the transverse movement drive unit 34 to move along the slide rail, and then the workpiece to be processed is clamped by the fixed seat 32 and the sliding seat 33. Specifically, the transverse movement drive unit 34 is specifically a telescopic cylinder.

[0033] Receiving grooves 35 are respectively formed on the outer walls of the fixed seat 32 and the sliding seat 33 facing each other. Preferably, the receiving grooves 35 can be designed according to the workpiece to be clamped, and can be designed according to a straight two-way joint or a two-way elbow, so as to clamp a straight two-way joint or a two-way elbow.

[0034] As a further embodiment provided by the present utility model, as Figure 1 shown in the figure, a mounting frame 6 is fixedly installed on the outer wall of the top of the drill press body 1. The lifting drive unit 4 is fixedly installed on the outer wall of the top of the mounting frame 6, and the output end of the lifting drive unit 4 penetrates through the mounting frame 6. The output end of the lifting drive unit 4 is connected to a connecting member 7, and the connecting member 7 is in transmission connection with the main shaft 2. Specifically, the connecting member 7 can be selected from mechanical components such as end face bearings for connecting the output end of the lifting unit and the main shaft 2. The lifting drive unit 4 and the main shaft 2 can be connected through the connecting member 7 to ensure that the end of the main shaft 2 rotates normally while the output end of the lifting drive unit 4 does not rotate. Preferably, the lifting drive unit 4 is a telescopic cylinder with a limit and an adjustable telescopic stroke, so as to prevent the main shaft 2 from descending too deeply and damaging the workpiece, and to be able to adjust the stroke of the main shaft 2 according to production requirements.

[0035] The cylinder is used as the lifting power source, which is clean and environmentally friendly. The improved equipment uses pneumatic control to reduce environmental pollution.

[0036] It should be noted that the output end of the lifting drive unit 4 has a slower speed during the descending process, which can prevent the main shaft 2 from descending too fast, resulting in excessive contact force between the edge sealing block 52 and the workpiece and causing damage to the workpiece.

[0037] A time relay is added inside the control box of the drilling machine body 1, and a new switch is connected in series to the power switch of the drilling machine body 1. During the processing, the operator needs to press two switches with both hands respectively to make the drilling machine body 1 energized, ensuring that the operator's hands are far away from the processing area during the processing, which can improve production safety. At the same time, the processing time can be controlled through the time relay. After being energized, the main shaft 2 rotates, and the lifting drive unit 4 drives the main shaft 2 to descend. After reaching the predetermined time, the time relay is powered off, and the lifting drive unit 4 resets to complete the processing. It should be noted that the above functions can be achieved through circuit connection, and the circuit connection is not the content protected by the present utility model. Those skilled in the art can change the circuit connection according to the functions to be achieved.

[0038] Working principle:

[0039] The workpiece is placed into the receiving groove 35 of the fixed seat 32, and then the transverse movement drive unit 34 drives the sliding seat 33 to slide, and the workpiece is fixed in the fixed seat 32 through the sliding seat 33;

[0040] Then, the two side switches are pressed, the drilling machine body 1 controls the main shaft 2 to rotate, and then the lifting drive unit 4 drives the main shaft 2 to descend;

[0041] During the descending process of the main shaft 2, the arc edge 523 of the edge sealing block 52 contacts and abuts against the outer wall of the end of the workpiece during the descending process of the mounting block 51. Since the arc edge 523 is arc-shaped, under the drive of the lifting drive unit 4, the edge of the end of the workpiece can be deformed along the arc edge 523 and bent inward to form a stepped structure, thereby limiting the parts inside the end of the workpiece to prevent the parts from coming out;

[0042] After the processing is completed, the main shaft 2 stops rotating and resets, and the sliding seat 33 resets, facilitating the clamping of the next workpiece.

[0043] Those skilled in the art can understand that other similar connection methods can also achieve the present utility model. For example, welding, bonding or screwing, etc.

[0044] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
