Synchronous puller

This creation relates to a type of puller, especially a type of puller.

A conventional puller is exemplified by the "Hydraulic Puller" of U.S. Patent No. 5,233,740, the puller of which is a design of a pivoting pivot and a link connecting jaw, thereby limiting the opening angle of the jaw. And the clamping action of the jaws requires the user to individually open or close the toggle, and after clamping the wheel-shaped object, the jaws need to be separately fixed to avoid the jaw displacement, which is inconvenient to use. .

Therefore, Taiwan Patent No. M274190 discloses a co-rotating type puller, which is shown in Fig. 1 and has a plurality of jaws 1, and the plurality of jaws 1 are connected to a central sleeve 3 by a link 2 The inner sleeve 3 is internally sleeved with a hydraulic rod 4, and the outer side has a threaded section 5, and the threaded section 5 is screwed with an adjusting ring 6 that is cooperating with the connecting rod 2, thereby rotating the adjusting ring 6 changing the position of the adjusting ring 6, the opening angle of the plurality of jaws 1 can be controlled through the connecting rod 2, and the plurality of jaws 1 can be clamped with a bearing 7, whereby the hydraulic rod can be pressed through The bearing 7 and the shaft 8 can be detached from a shaft 8 in the bearing 7.

According to the prior art, the plurality of jaws 1 can be simultaneously opened by the driving of the connecting rod 2, which can reduce the inconvenience of operation. However, the structure of the connecting rod 2 has many components and is troublesome in assembly. And its requirements for the accuracy of manufacturing, when the manufacturing error is too large, the assembled structure will be unsatisfactory and quickly damaged, and even interfere with each other and can not move.

The main purpose of this creation is to solve the problem of high cost due to the complicated assembly and excessive precision of conventional articulated puller assembly.

In order to achieve the above object, the present invention provides a co-rotating puller comprising a puller seat, a pusher assembly, an opening and closing control member and a plurality of jaws, the wheelbarrow seat including a central bushing and a coaxial connection a connecting portion of the central bushing, the central bushing having an outer flange for pressing an elastic body and a threaded portion extending outwardly from the outer flange, the propulsion assembly passing through a central axis of the puller seat a sleeve, the opening and closing control member is screwed to the threaded portion and axially displaced relative to the outer flange, the plurality of jaws are respectively pivotally connected to the connecting portion, and the plurality of jaws each have a protruding portion disposed on the elastic body and a protruding rod between the opening and closing control members.

According to the present invention, the elastic body and the opening and closing control member respectively press the protruding rod from both sides, and the position of the protruding rod is adjusted by the axial displacement of the opening and closing control member, thereby driving the plurality of clamping jaws. The pivoting, thereby allowing the plurality of jaws to simultaneously condense or open, has a simple structure, is easy to manufacture, and is low in cost, and can meet the demand for cost reduction.

The detailed description and technical content of this creation are as follows:

Please refer to FIG. 2 and FIG. 3 , which is a co-operating puller comprising a wheel puller 10 , a propulsion assembly 20 , an opening and closing control member 30 and a plurality of jaws 40 . The pulley base 10 includes a central bushing 11 and a connecting portion 12 coaxially connected to the central bushing 11, wherein the connecting portion 12 can be screwed to the outer side of the central bushing 11 and has a plurality of bumps 13 The plurality of bumps 13 are radially arranged around the central sleeve 11 , and the connecting portion 12 can further form a fixing block 14 facing outwards, and the fixing block 14 locks a hand grip 50 for holding And the central bushing 11 has an outer flange 15 for pressing an elastic body 60 and a threaded section 16 extending outwardly from the outer flange 15.

The propulsion assembly 20 includes a hydraulic operating lever 21, a hydraulic tank 22, a fixing portion 23 and a pushing rod 24, wherein the fixing portion 23 is screwed and fixed in the central bushing 11, the hydraulic operating lever The hydraulic pressure change of the oil pressure tank 22 is controlled by a link mechanism 25, and the hydraulic pressure tank 22 is locked and fixed to the fixing portion 23, and the pushing rod 24 is relatively slipped and sleeved on the fixing portion 23. And the oil pressure tank 22 is driven by the oil pressure of the oil pressure tank 22 to change the position, and the hydraulic operation lever 21 can be extendedly connected with an extension rod 211 to increase the force arm and reduce the required operating force. .

The opening and closing control member 30 is screwed to the threaded portion 16 and axially displaced relative to the outer flange 15 . The plurality of clamping jaws 40 are respectively pivotally connected to the connecting portion 12 . More precisely, the protruding block 13 has the same a plurality of slots 131 are inserted into the jaws 40, and the rivets 70 are passed through the jaws 40 and the notches 131, and the plurality of jaws 40 are pivotally connected to the plurality of bumps 13 one by one, and The plurality of jaws 40 each have a protruding rod 41 extending between the elastic body 60 and the opening and closing control member 30.

The central sleeve 11 can be sleeved with an upper pressing ring 80. The upper pressing ring 80 is located between the protruding rod 41 and the elastic body 60. The elastic body 60 can be a spring to pass through the spring. The protruding rod 41 is stably displaced by the pressing ring 80; similarly, the central bushing 11 can also be sleeved with the pressing ring 90, and the lower pressing ring 90 is located at the protruding rod 41 and the opening and closing control member. Between 30, it can increase the stability of the opening and closing control member 30 to shift the displacement of the protruding rod 41.

Please refer to FIG. 4 again. Since the elastic body 60 and the opening and closing control member 30 respectively press the protruding rod 41 from both sides, the present invention can adjust the rotation control member 30 by rotating the opening and closing control member 30. The position of the opening and closing control member 30 relative to the outer flange 15 can adjust the position of the protruding rod 41, thereby driving the plurality of jaws 40 to pivot, so that the plurality of jaws 40 can be simultaneously condensed or opened.

Please refer to the figure shown in Figure 5, so this creation can be used for the wheel puller. The wheel body can be bearings, ball bearings, gears and pulleys. Taking the bearing as an example, if the shaft 100 and the bearing 110 are to be separated, firstly, the plurality of jaws 40 are first opened to cover the bearing 110, and the plurality of jaws 40 are condensed to clamp the bearing 110, and then the oil pressure is used. The operating rod 21 axially displaces the pushing rod 24 to press the pushing rod 24 against the shaft 100, and finally the displacement rod 24 is continuously displaced, thereby generating an opposite force to the shaft 100 and the bearing. 110 separation.

As described above, the present invention is configured to control the opening and closing control by the elastic body and the opening and closing control member by pressing the protruding rods from both sides, and utilizing the elastic force of the elastic body and the pushing and pressing of the opening and closing control member. The axial displacement of the piece, and adjusting the position of the protruding rod, thereby driving the plurality of jaws to pivot, can also make the plurality of jaws condense or open at the same time to meet the needs of the pulling operation. The overall structure is simple, easy to manufacture and low in cost, and can meet the demand for cost reduction.

The present invention has been described in detail above, but the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited. That is, the equivalent changes and modifications made in accordance with the scope of this creation application shall remain within the scope of the patent of this creation.
