In order to prevent the hose from being separated from the connector, the hose is usually required to be arranged in a gland, and when the hose is connected, the gland presses the hose on the connector. The pipe pressing machine is used for penetrating the joint into the hose so that the pressing cover presses the hose on the joint. In the prior art, the problem that the length of the joint penetrating through the hose is not easy to adjust exists.
Disclosure of Invention
In view of the foregoing, it is desirable to provide a tube pressing machine and an adjusting structure for conveniently adjusting the length of the joint penetrating the hose.
An adjustment structure, comprising:
The adjusting rod comprises a penetrating section and a threaded section;
The first abutting piece comprises a first abutting piece and a penetrating part arranged on the first abutting piece, wherein the penetrating part is movably sleeved on the penetrating section or movably penetrated in the penetrating section;
The second abutting piece is screwed on the threaded section and comprises a second abutting piece and a sleeve arranged on the second abutting piece; and

The adjusting structure has at least the following advantages:
When the movable table is used, the threaded section is arranged on the machine frame in a penetrating way and is in threaded fit with the machine frame, and the first abutting piece is arranged on the movable table or abuts against the movable table on one side, opposite to the elastic piece, of the first abutting piece. Before connection, the hose is limited on the mobile station so that the hose drives the mobile station to move.
If the length of the joint penetrating the hose is required to be shorter, the threaded section is rotated, and the first abutting piece and the second abutting piece are mutually close due to the fact that the threaded section is in threaded fit with the frame, and one side of the first abutting piece, which is opposite to the elastic piece, is arranged on or abuts against the moving table, so that the length of the penetrating part, which is sleeved on the penetrating section, is increased, or the length of the penetrating part, which is penetrated in the penetrating section, is increased. And/or, rotate the second abutting piece, because the second abutting piece is threaded on the threaded section, can make the second abutting piece close to the first abutting piece along the length direction of the threaded section.
When the connector is connected, after the connector penetrates through the hose, the connector drives the mobile station with the hose to move, the mobile station compresses the elastic piece, and one end of the elastic piece is propped against the first propping piece, the other end of the elastic piece is propped against the second propping piece, and the distance between the first propping piece and the second propping piece is relatively short, so that the length of the elastic piece which can be indirectly compressed by the connector is relatively short, and the connector penetrates through the hose is relatively short.
If the length of the joint penetrating the hose is required to be longer, the threaded section is reversely rotated, so that the length of the penetrating part sleeved on the penetrating section is reduced or the length of the penetrating part penetrating the penetrating section is reduced, and the first abutting piece and the second abutting piece are mutually far away. And/or reversely rotating the second abutting piece, wherein the second abutting piece is screwed on the threaded section, so that the second abutting piece can be far away from the first abutting piece along the length direction of the threaded section.

The first extending part extends into one of the pipelines, and the second extending part extends into the other pipeline. One gland bush is arranged on the first extending part and the pipeline which is extended by the first extending part, and the other gland bush is arranged on the second extending part and the pipeline which is extended by the second extending part.
Referring to fig. 1, a tube pressing machine 10 in an embodiment is used for inserting a joint into a hose so that a gland presses the hose onto the joint, and the tube pressing machine 10 has at least a feature of being capable of conveniently adjusting the length of the joint inserted into the hose. Specifically, the tube pressing machine 10 includes a frame 100, a fixing plate 200, a first power mechanism 300, a mount 400, a moving stage 500, and an adjusting structure 600.
The frame 100 includes a base 110 and a protective cover 120 disposed on the base 110, wherein the base 110 mainly supports and the protective cover 120 mainly protects. In the present embodiment, the fixing plate 200 and the first power mechanism 300 are disposed on the base 110, and the fixing plate 200, the first power mechanism 300, the mounting member 400 and the mobile station 500 are disposed in the protection cover 120. Foot pads 130 may also be provided at the bottom of the housing 110 to provide shock absorption on the one hand and to provide increased placement stability for the pipe press 10 on the other hand. Of course, in other embodiments, the shield 120 and/or footpad 130 may be omitted.
The fixing plate 200 is provided with a first clamping groove 210, and the gland with the hose in a penetrating manner is placed in the first clamping groove 210, so that the gland is limited by the first clamping groove 210, and the gland is prevented from moving when the joint is penetrated. In the present embodiment, the first clamping groove 210 is formed on the top of the fixing plate 200, so that the pressing cover is placed in the first clamping groove 210 from above the fixing plate 200. Of course, in other embodiments, the opening position of the first slot 210 may be flexibly set, such as a side portion of the fixing plate 200.
Referring to fig. 2, a first power mechanism 300 is provided for powering the threading of the joint. The first power mechanism 300 includes a protrusion 310, and the distance between the protrusion 310 and the fixing plate 200 can be changed to drive the joint to move along the penetrating direction. In the present embodiment, the first power mechanism 300 is a cylinder, and the extension member 310 is a piston rod of the cylinder. Of course, in other embodiments, the first power mechanism 300 may also be a hydraulic cylinder, a motor, a screw nut pair, or the like.
The mounting member 400 is provided on the extension member 310, and the mounting member 400 is used for mounting the joint. The mounting member 400 is provided with a mounting hole 410, and when the mounting member is mounted, the first extending portion or the second extending portion can extend into the mounting hole 410, so as to mount the connector on the mounting member 400. The orifice of the mounting hole 410 faces the first clamping groove 210, so that the joint mounted on the mounting piece 400 can be accurately aligned with the hose penetrating the gland in the first clamping groove 210.
Protrusions may be provided on the mouth wall of the mounting hole 410, and grooves matching with the protrusions may be provided on the first or second protruding portions to increase the mounting stability of the joint on the mounting member 400. Alternatively, a groove may be formed on the wall of the mounting hole 410, and a protrusion matching the groove may be formed on the first or second protruding portion to increase the mounting stability of the connector on the mounting member 400. In this embodiment, the mounting member 400 has a cylindrical shape. Of course, in other embodiments, the shape of the mount 400 may be flexibly designed, such as a clip-like shape, to enable the mounting of the fitting on the mount 400 using clamping.
The mobile station 500 is used to carry a hose to facilitate restraining the hose to the mobile station 500. The mobile station 500 is movably disposed on the frame 100, and when the connector is inserted into the hose, the mobile station 500 moves under the action of the connector, so as to avoid the hose from being subjected to excessive force in a short time. The mobile station 500 is positioned on the side of the fixed plate 200 facing away from the extension 310, and is reasonably arranged. The positional relationship among the mobile station 500, the fixed plate 200, and the extension member 310 should be viewed in a state where the extension member 310 is not extended. When the extension member 310 is extended, the extension member 310 may extend into the first card slot 210.
Referring to fig. 3, an adjusting structure 600 of an embodiment may be applied to the pipe pressing machine 10 to adjust the length of the joint penetrating the hose. Specifically, the adjusting structure 600 includes an adjusting lever 610, a first abutting member 620, a second abutting member 630, and an elastic member 640. The adjustment rod 610 includes a threaded section 612 and a threaded section 611. The first contact element 620 includes a first contact piece 621 and a penetrating portion 622 disposed on the first contact piece 621, where the penetrating portion 622 is movably sleeved on the penetrating segment 611, or the penetrating portion 622 is movably sleeved in the penetrating segment 611. The second abutting piece 630 is screwed on the threaded section 612, and the second abutting piece 630 comprises a second abutting piece 631 and a sleeve 632 arranged on the second abutting piece 631. The elastic member 640 is sleeved on the adjusting rod 610, the penetrating portion 622 and the sleeve 632, one end of the elastic member 640 abuts against the first abutting piece 621, and the other end abuts against the second abutting piece 631.
In use, the threaded section 612 is threaded through the frame 100 and is in threaded engagement with the frame 100, and the first abutment piece 621 is disposed on the mobile station 500 or the side of the first abutment piece 621 facing away from the elastic member 640 abuts against the mobile station 500. Before connection, the hose is placed on the mobile station 500 so that the hose moves the mobile station 500.
If the length of the joint penetrating the hose is required to be shorter, the threaded section 612 is rotated, and the threaded section 612 is in threaded engagement with the frame 100, and the first abutment piece 621 is disposed on the mobile station 500 or the side of the first abutment piece 621 opposite to the elastic member 640 abuts against the mobile station 500, so that the length of the penetrating portion 622 sleeved on the penetrating section 611 is increased or the length of the penetrating portion 622 penetrating the penetrating section 611 is increased, and the first abutment piece 621 and the second abutment piece 631 are close to each other. Or the second abutting piece 630 is rotated, and the second abutting piece 630 is screwed on the threaded section 612, so that the second abutting piece 630 can be close to the first abutting piece 621 along the length direction of the threaded section 612.
When the connector is connected, after the connector is inserted into the hose, the connector drives the mobile station 500 with the hose placed therein to move, the mobile station 500 compresses the elastic member 640, and since one end of the elastic member 640 abuts against the first abutment piece 621 and the other end abuts against the second abutment piece 631, and the distance between the first abutment piece 621 and the second abutment piece 631 is relatively short, the length of the elastic member 640 that can be indirectly compressed by the connector is relatively short, so that the length of the connector inserted into the hose is relatively short.
If the length of the joint passing through the hose is required to be longer, the threaded section 612 is reversely rotated, so that the length of the passing portion 622 sleeved on the passing section 611 is reduced or the length of the passing portion 622 passing through the passing section 611 is reduced, and the first abutting piece 621 and the second abutting piece 631 are mutually far away. Or the second abutting piece 630 is reversely rotated, and the second abutting piece 630 is screwed on the threaded section 612, so that the second abutting piece 630 can be far away from the first abutting piece 621 along the length direction of the threaded section 612.
When the connector is connected, after the connector is inserted into the hose, the connector drives the mobile station 500 for placing the hose to move, and the mobile station 500 compresses the elastic member 640, because one end of the elastic member 640 abuts against the first abutting piece 621, the other end abuts against the second abutting piece 631, and the distance between the first abutting piece 621 and the second abutting piece 631 is far, the length of the elastic member 640 which can be indirectly compressed by the connector is long, so that the length of the connector inserted into the hose is long.
By the adjusting structure 600, the length of the elastic member 640 that can be indirectly compressed by the connector can be changed by rotating the threaded section 612 in different directions and/or rotating the second abutting member 630 in different directions, so as to conveniently adjust the length of the connector penetrating into the hose. In addition, the elastic member 640 can also play a certain role in buffering so as to prevent the hose directly connected with the gland from buckling along the radial direction of the hose, thereby ensuring the connection quality.
In this embodiment, the penetrating segment 611 is a polished rod segment, and the surface is not tapped with threads and has low friction. Of course, in other embodiments, the surface of the penetrating segment 611 may be threaded.
Further, the adjusting rod 610 further includes an adjusting wheel 613, the adjusting wheel 613 is disposed on an end of the threaded section 612 away from the penetrating section 611, and the adjusting wheel 613 protrudes from the threaded section 612 along a radial direction of the threaded section 612. The screw thread segments 612 can be rotated by rotating the adjustment wheel 613, and the presence of the adjustment wheel 613 can increase the rotational convenience of the screw thread segments 612. Knurling may be formed on the outer surface of the adjustment wheel 613 to increase friction, facilitating the operator to rotate the adjustment wheel 613. Of course, in other embodiments, the adjustment wheel 613 may be omitted.
In this embodiment, the penetrating portion 622 is cylindrical, and the penetrating portion 622 is sleeved on the penetrating segment 611. The side of the first abutment piece 621 facing away from the elastic member 640 abuts against the mobile station 500 to facilitate separation of the first abutment piece 621 from the mobile station 500, thereby facilitating replacement of the first abutment piece 620 or the mobile station 500. The first abutment piece 621 has a circular sheet shape so as to block the penetrating portion 622. Of course, in other embodiments, the first abutment piece 621 can be disposed on the mobile station 500. A receiving hole may be formed in the penetrating segment 611, and the penetrating portion 622 may be penetrated into the receiving hole. The first abutment piece 621 has an annular sheet shape so that a space surrounded by the first abutment piece 621 communicates with the penetrating portion 622 having a cylindrical shape. It will be appreciated that the first abutment 620 should have a certain length along the length of the adjustment rod 610 so that the adjustment rod 610 is threaded to different depths of the first abutment 620.
An internal screw may be tapped on the second abutment plate 631 and/or the sleeve 632 to facilitate the screwing of the second abutment 630 onto the threaded section 612. In the present embodiment, the second abutment piece 631 has an annular shape so as to be sleeved on the threaded section 612.

Referring to fig. 1 to 4, the specific working principles of the tube pressing machine 10 and the adjusting structure 600 in this embodiment are as follows:
Before connection, the connector is mounted on the mounting member 400, the gland through which the hose is threaded is placed in the first clamping groove 210, and the hose is placed in the second limiting groove 821.
If the length of the joint penetrating the hose is required to be shorter, the threaded section 612 is rotated, and the threaded section 612 is in threaded engagement with the adjusting block 140, and the side of the first abutting piece 621 opposite to the elastic piece 640 abuts against the mobile station 500, so that the length of the penetrating portion 622 sleeved on the penetrating section 611 is increased, and the first abutting piece 621 and the second abutting piece 631 approach each other. And/or, the second abutting piece 630 is rotated, and as the second abutting piece 630 is screwed on the threaded section 612, the second abutting piece 630 can be made to approach the first abutting piece 621 along the length direction of the threaded section 612.
When in connection, the power piece 710 drives the pressing seat 720 to be close to the fixing plate 200 so as to press the pressing cover into the first clamping groove 210. The first power mechanism 300 is operated, and the extension member 310 approaches the fixing plate 200 along the penetrating direction of the joint, so that the joint is penetrated in the hose. The power source 811 drives the limit seat 812 to approach the limit bracket 820, so that the hose is limited on the mobile station 500 by using the limit seat 812 and the limit bracket 820. When the connector is inserted into the hose, the connector drives the mobile station 500 for placing the hose to move, the mobile station 500 compresses the elastic member 640, and the elastic member 640 has a shorter length that the connector can be indirectly compressed by the connector because one end of the elastic member 640 abuts against the first abutting piece 621, the other end abuts against the second abutting piece 631, and the distance between the first abutting piece 621 and the second abutting piece 631 is shorter. After the connection is completed, the pressing seat 720, the extension member 310 and the limiting seat 812 are reset.
If the length of the joint passing through the hose is required to be longer, the threaded section 612 is reversely rotated, so that the length of the passing portion 622 sleeved on the passing section 611 is reduced, and the first abutting piece 621 and the second abutting piece 631 are mutually far away. And/or, the second abutting piece 630 is reversely rotated, and as the second abutting piece 630 is screwed on the threaded section 612, the second abutting piece 630 can be far away from the first abutting piece 621 along the length direction of the threaded section 612.
When in connection, the power piece 710 drives the pressing seat 720 to be close to the fixing plate 200 so as to press the pressing cover into the first clamping groove 210. The first power mechanism 300 is operated, and the extension member 310 approaches the fixing plate 200 along the penetrating direction of the joint, so that the joint is penetrated in the hose. The power source 811 drives the limit seat 812 to approach the limit bracket 820, so that the hose is limited on the mobile station 500 by using the limit seat 812 and the limit bracket 820. When the connector is inserted into the hose, the connector drives the mobile station 500 for placing the hose to move, the mobile station 500 compresses the elastic member 640, one end of the elastic member 640 abuts against the first abutting piece 621, the other end abuts against the second abutting piece 631, and the distance between the first abutting piece 621 and the second abutting piece 631 is far, so that the length of the elastic member 640 which can be indirectly compressed by the connector is long, and the length of the connector inserted into the hose is long. After the connection is completed, the pressing seat 720, the extension member 310 and the limiting seat 812 are reset.
The pipe pressing machine 10 and the adjusting structure 600 can change the length of the elastic member 640 that can be indirectly compressed by the connector by rotating the threaded section 612 in different directions and/or rotating the second abutting member 630 in different directions, so as to conveniently adjust the length of the connector penetrating into the hose.
