Description

Technical Field

[0001] The utility model relates to the field of sheet metal hand tools, in particular to a draw head, a draw cup and a draw assembly that can be automatically clamped. Background Technique

[0002] Generally, hand tools for sheet metal are often used in vehicle body sheet metal adjustment or repair operations. From the early manual correction and repair by manpower to the present, many mechanical hand tools that can replace manpower have been developed, thus improving the efficiency of sheet metal repair and correction work.

[0003] For general sheet metal correction work, a draw tool is used to adjust or correct the deformed sheet metal surface. Therefore, a cup is usually detachably installed at the front end of the draw tool. After the draw tool adsorbs on the sheet metal surface through the cup, appropriate force is applied to adjust or repair the sheet metal surface.

[0004] Since there are many sizes of existing cups, and there are also various different design styles for the draw heads at the connection parts of the cups to the draw tools. The common connection part of the draw head is usually designed as a T-shaped groove (a blind groove that is not through and is in a T shape is opened on the draw head), so that when the cup is installed into the draw head (usually a draw head with a T shape is designed), one side can abut against the inner side where the T-shaped groove is not opened, so that the cup can only be taken out from the open side of the draw head, and it can also prevent the lateral sliding force from being generated during the adsorption process of the cup, and it is not easy to slide out of the draw head along the lateral direction.

[0005] However, the foregoing setting is not easy to apply to cups with a larger area. Because, in order to increase the contact area, the connection part of the cup with a larger area has been changed from a T-shaped joint to a T-shaped beam joint. Such a cup cannot be installed into a general draw head with a T-shaped groove, because the T-shaped groove of the draw head is closed at one end, and the length of the beam design is relatively long, and only a little end can penetrate into the T-shaped groove, and effective force cannot be applied. Therefore, another draw head with a T-shaped through hole has been derived. Since the T-shaped through hole of this kind of draw head directly penetrates both sides, the draw head with a T-shaped beam connection can also be universal, improving the applicable effect.

[0006] However, although the draw head with a T-shaped through hole solves the installation problem, it has also derived the problem of lateral sliding. In the general axial force application direction of the draw tool, the closed surface on one side of the original T-shaped groove design can resist sliding, but the T-shaped hole design lacks a surface to block sliding, and it is easy to slide when pulling with force. In order to solve the problems existing in the existing draw heads, the inventor proposed the concept of this design to improve the defects existing in the draw heads of existing sheet metal hand tools.

[0046] Various structural schematic diagrams according to the disclosed embodiments of the present utility model are shown in the drawings. These figures are not drawn to scale, where for the purpose of clear expression, some details are enlarged and some details may be omitted. The shapes of various regions and layers shown in the figures and their relative sizes and positional relationships are only exemplary, and may actually deviate due to manufacturing tolerances or technical limitations, and those skilled in the art can design regions / layers with different shapes, sizes and relative positions according to actual needs.

[0047] As Figures 1 to 4 shown, the present utility model discloses a drawbar hanger head that can be automatically clamped. The drawbar hanger head 10 includes a drawbar shaft 11, a movable sleeve 12, a fixed cylinder base 13 and a positioning element 14.

[0048] The drawing shaft 11 described above is a round rod with two stages of different diameters. At one end of the drawing shaft 11, a clamping portion 110 is provided. The clamping portion 110 is horizontally penetrated by a T-shaped through hole to form a clamping opening 111. One end of the suction cup can be fixed to the clamping opening 111. At the other end of the drawing shaft 11, there is a connecting portion 112 that can be connected to the drawing shaft 11. The connecting portion 112 is cylindrical and has a diameter smaller than that of the clamping portion 110. The connecting portion 112 can be used to fix to a puller. In this embodiment, the connecting portion 112 is further provided with an interface 113. Commonly used pullers usually have a thread at one end. The interface 113 of the connecting portion 112 is provided with a thread, which corresponds to the thread of the commonly used puller, so that the puller can be screwed and fixed to the interface 113 of the connecting portion 112. This part of the connecting portion 112 can be combined with the puller in various ways. The form of the foregoing interface 113 is only an example. The connecting portion 112 includes, but is not limited to, being detachably connected in a separable manner such as screwing, clamping, or snap-fitting, or being integrally formed inseparably at one end of a specific puller, which are all within the scope claimed by the present utility model.

[0049] The movable sleeve 12 described above can slide along the axial direction of the drawing shaft 11 and is sleeved outside the drawing shaft 11. More specifically, the movable sleeve 12 is sleeved outside the connecting portion 112 of the drawing shaft 11. The movable sleeve 12 is a stepped sleeve with two different diameters, including a clamping sleeve portion 121 and a pressing sleeve portion 122 connected to the clamping sleeve portion 121. The inner diameter of the clamping sleeve portion 121 is greater than or equal to the clamping portion 110 of the drawing shaft 11, and the length is slightly greater than the length of the clamping portion 110. The movable sleeve 12 is slidably sleeved outside the connecting portion 112 of the drawing shaft 11 with the pressing sleeve portion 122, and a pressing end 123 is formed at one end of the pressing sleeve portion 122 different from the end connected to the clamping sleeve portion 121. A limiting surface 124 is formed on the inner edge of the clamping sleeve portion 121. This limiting surface 124 can be in contact with the rear of the clamping portion 110 without applying force. When the movable sleeve 12 slides, this limiting surface 124 and the clamping portion 110 are also used as the limiting end points. The moving area of the movable sleeve 12 will not exceed this position.

[0050] The movable sleeve 12 can slide on the drawing shaft 11 with the pressing sleeve portion 122. When the pressing sleeve portion 122 presses against the rear side of the clamping portion 110 of the drawing shaft 11, the clamping sleeve portion 121 can cover the entire periphery of the clamping portion 110.

[0051] The fixed cylinder base 13 is a circular cylindrical seat body. The inner diameter of the fixed cylinder base 13 is greater than or equal to the outer diameter of the abutting sleeve portion 122 of the movable sleeve 12, enabling the movable sleeve 12 to slide inside the fixed cylinder base 13 and displace along the axial direction of the fixed cylinder base 13. The drawing shaft 11 and the movable sleeve 12 are partially arranged inside the fixed cylinder base 13. In this embodiment, an opening 131 corresponding to the interface 113 of the drawing shaft 11 is provided at the end of the fixed cylinder base 13, and the opening 131 is used to connect the interface 113 of the drawing shaft 11 to a puller.

[0052] The positioning element 14 is selectively disposed between the fixed cylinder base 13 and the movable sleeve 12, or selectively arranged between the drawing shaft 11 and the movable sleeve 13. The purpose of the positioning element 14 is to relatively position the movable sleeve 12 and the drawing shaft 11. In this embodiment, the positioning element 14 is a compression spring and is arranged between the fixed cylinder base 13 and the movable sleeve 12, and is sleeved around the connecting portion 112 of the drawing shaft 11. When the movable sleeve 12 moves relative to the end of the fixed cylinder base 13 due to an external force, the abutting sleeve portion 12 of the movable sleeve 12 will compress the positioning element 14 at this time. When the movable sleeve 12 is not affected by an external force, the positioning element 14 will rebound and reset the movable sleeve 12.

[0053] In addition to using a compression spring for positioning and rebounding, the user can also select other mechanical parts such as clamping, magnetic attraction, spiral, etc. in different ways to position the movable sleeve relative to the drawing shaft.

[0054] For example, magnets are respectively arranged at the front and rear positions inside the movable sleeve, and magnets are also arranged at the positions on the drawing shaft corresponding to the movable sleeve for positioning. By moving the position of the movable sleeve, the magnetic force of the magnets is adsorbed to the corresponding positions to position the movable sleeve.

[0055] Or elastic beads for positioning and clamping are arranged on the drawing shaft, and grooves are arranged at different positions of the movable sleeve. By sliding, the grooves of the movable sleeve are clamped on the elastic beads to position the movable sleeve.

[0056] Or corresponding clamping structures are respectively provided on the inner sides of the drawing shaft and the movable sleeve or on the inner sides of the movable sleeve and the fixed cylinder base, and the movable sleeve is positioned by sliding either one.

[0057] The positioning element generally refers to a way that enables the movable sleeve to act relative to the drawing shaft or enables the movable sleeve to act relative to the fixed cylinder base, and can position the movable sleeve at a certain place, so that the clamping portion at the front end of the drawing shaft can be exposed relative to the movable sleeve. The present invention does not limit the specific form here, as long as a similar function can be achieved, it falls within the scope explained by the present invention.

[0058] The present utility model further discloses a puller assembly, which includes the aforementioned puller head 10 capable of automatic clamping, a puller suction cup 20, and a puller 30. The puller suction cup 20 is detachably connected to the puller head 10, and the puller head 10 is detachably installed at one end of the puller 30.

[0059] Among them, the puller suction cup 20 can be detachably connected to the puller head 10, and includes a head connection seat 21, a movable disk body 22, a detachable joint 23, and an elastic element 24.

[0060] The head connection seat 21 is a convex-shaped hollow seat body, and includes a sleeve portion 210, an abutting portion 211, and a hanging seat portion 212 integrally formed at the end of the sleeve portion 210. The sleeve portion 210 is a hollow cylindrical shape. The abutting portion 211 is formed inside the sleeve portion 210 and communicates with the hanging seat portion 212. The abutting portion 211 is a through hole penetrating the sleeve portion 210 and the hanging seat portion 212, and an abutting surface 214 is formed at the bottom of the sleeve portion 210 for placing the elastic element 24. The hanging seat portion 212 is disk-shaped and has a groove 215.

[0061] The movable disk body 22 is a T-shaped solid, which is slidably arranged in the sleeve portion 210 of the head connection seat, and part of it can extend out of the groove 215 of the head connection seat 21, forming a disk surface 220 with a large area at one end. A sliding shaft rod 221 extending along the axial direction is formed in the center of the movable disk body 22. The sliding shaft rod 221 is a multi-stage stepped rod, and its diameter gradually decreases from the disk surface 220 in the direction away from the disk surface 220. A stepped section 222 for abutting the elastic element 24 and a threaded section 223 for connecting the detachable joint 23 at the end are formed on the sliding shaft rod 221.

[0062] The movable disk body 22 is inserted into the sleeve portion 210 of the head connection seat 21 with the sliding shaft rod 221, and is slidably telescopically arranged in the groove 215 of the hanging seat portion 212 with the threaded section 223.

[0063] The detachable joint 23 is detachably connected to the threaded section 223 of the sliding shaft rod 221. The contour of the detachable joint 23 matches the clamping opening 111 of the aforementioned puller head 10. The puller suction cup 20 can penetrate the clamping opening 111 with the detachable joint 23 and be fixed on the puller head 10 by being clamped by the movable sleeve 12 and the puller shaft 11.

[0064] The elastic element 24 is a compression spring sleeved outside the sliding shaft rod 221 of the movable disk body 22, and its two ends respectively abut between the stepped section 222 of the movable disk body 22 and the abutting portion 211 of the hanging head connection base 21. When an external force acts on the movable disk body 22, the elastic element 24 will be compressed and the sliding shaft rod 221 will protrude out of the groove 215 of the hanging seat portion 212, so that the detachable joint 23 can be exposed outside the hanging seat portion 212, and then be connected to the clamping opening 111 of the pulling head 10 of the puller; after the aforesaid external force disappears, the elastic element 24 will rebound, causing the movable disk body 22 to return to its original position.

[0065] The puller 30 includes a holding sleeve 31, a pull rod 32 and a pulling sleeve 33. A lubricating element 310 is arranged inside the front end of the holding sleeve 31. The lubricating element 310 is a common linear bearing or an oil-free bushing. A pull rod hole 311 is formed through the center of the holding sleeve 31, and an axially extending positioning groove 312 is formed on the inner side surface of the pull rod hole 311.

[0066] The pull rod 32 is arranged inside the holding sleeve 31 so as to be axially movable along the holding sleeve 31. One end of the pull rod 32 is provided with a connecting rod portion 321 capable of connecting with the pulling head 10 of the puller. In this embodiment, the connecting rod portion 321 is a thread whose shape matches the interface 113 of the pulling shaft 11, and the pull rod 32 can be connected with the pulling head 10 of the puller in a screwing manner.

[0067] A spring 322 and a buckle 323 are arranged at the end of the pull rod 32 different from the connecting rod portion 321. The spring 322 is sleeved at the end of the pull rod 32. When the buckle 323 penetrates into the holding sleeve 31, it will be stuck in the positioning groove 311. When the holding sleeve 31 is rotated and actuated, the buckle 323 and the pull rod 32 will be rotated together. At this time, the spring 322 is compressed due to the axial displacement of the buckle 323, thereby affecting the elastic force of the spring 322. When the holding sleeve 31 is rotated to a specific position, the spring 322 will be completely compressed and lose its elastic force. At this time, the pull rod 32 will slide inside the holding sleeve 31 without elastic force. When the spring 322 inside the holding sleeve 31 is released due to different rotation positions, at this time the spring 322 will carry elastic force and be able to make the pull rod 32 also have elastic force.

[0068] The pulling sleeve 33 is arranged and fixed outside the pull rod 32 and is located in front of the holding sleeve 31.

[0069] The implementation manner of the puller assembly of the present utility model is as Figure 1 、 Figure 7 、 Figure 8As shown in the figure, when the hanging head 10 of the puller of the present utility model is detachably connected to the puller 30, the position of the movable sleeve 12 can be adjusted to clamp or fix the puller suction cup 20 provided on the clamping portion 110 of the puller shaft 11, so that the puller suction cup 20 can be more firmly connected to the hanging head 10 of the puller and can adapt to puller suction cups 20 of different sizes.

[0070] Through the design of the puller suction cup 20 in the present utility model, the movable disk body 22 can slide axially along the hanging head connection seat 21, so that the detachable joint 23 can protrude outside the hanging head connection seat 21 and then be inserted into the clamping opening 111 of the hanging head 10 of the puller. By releasing the movable sleeve 12, the positioning element 14 can rebound, and the movable sleeve 12 can clamp the detachable joint 23 of the puller suction cup 20 for fixation.

[0071] The beneficial effect of the present utility model is that the hanging head of the puller of the present utility model can be arbitrarily combined with the existing puller or tools with similar functions. When the puller shaft of the hanging head of the puller is fixed to the puller, when installing the suction cup on the hanging head of the puller, the position of the movable sleeve can be adjusted to clamp or fix the suction cup provided on the clamping portion, so that the suction cup can be more firmly connected to the hanging head of the puller and can adapt to suction cups of different sizes.

[0072] In addition, the puller assembly further includes a combination of a puller hanging head and a puller suction cup. At the puller hanging head, the puller suction cup can be more firmly clamped through the movable sleeve. And the movable disk body of the puller suction cup can push the detachable joint towards the puller hanging head relative to the hanging head connection seat, and the detachable joint can be combined with the puller hanging head. After the detachable joint is combined with the puller head, it rebounds and retracts with the elastic element, generating a clamping force in another direction, thereby improving the connection strength between the puller suction cup and the puller hanging head.

[0073] Furthermore, it can be further paired with a puller. By rotating its holding sleeve, the state of the pull rod can be adjusted, so that the pull rod can selectively generate elastic force or not generate elastic force, thereby improving its usability.

[0074] The overall puller assembly combination can provide users with more choices and can also be used in combination with different pullers or suction cups. Different usage effects can be generated through the combination of different components.

[0075] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art, within the scope of the technical solution of the present utility model, can make some changes or modifications to the above-disclosed technical content to form equivalent embodiments with equivalent changes. However, as long as the content does not depart from the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
