DETAILED DESCRIPTION

[0024] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0025] like Figure 1 As shown, the present disclosure provides a clamp, including a base 1, a sliding device 2, an abutment device 3 and a clamping device 4. The clamp provided by the present disclosure is used to fix a cylindrical component, and the cylindrical component includes a top cover, a cylinder and a bottom cover. The clamp of the present disclosure fixes the cylinder, and then abuts the top cover and the bottom cover on the two ends of the cylinder respectively, so that the top cover, the cylinder and the bottom cover are coaxially arranged, which is convenient for subsequent welding of the top cover and the bottom cover to the cylinder.

[0026] like Figure 2 and 3 As shown, the sliding device 2 includes a guide rail 21, a sliding member 22 and a positioning member 23, and the guide rail 21 is fixed on the base 1 by bolts or welding technology.

[0027] The sliding member 22 includes a slider 221 and a carrier plate 222. The slider 221 is slidably connected to the guide rail 21. The slider 221 is provided with a positioning hole 2211. The positioning member 23 is passed through the positioning hole 2211, and the end of the positioning member 23 abuts against the guide rail 21, so that the slider 221 is fixed on the guide rail 21. The carrier plate 222 is fixed to the slider 221 by bolts or welding technology, and the carrier plate 222 is connected to the clamping device 4.

[0028] The positioning hole 2211 is a threaded hole, and the positioning member 23 is a bolt matched with the threaded hole.

[0029] By setting a guide rail 21 and a slider 221 slidably connected to the guide rail 21, the clamping device 4 is connected to the slider 221 through a loading plate 222, so that the clamping device slides along the guide rail 21 through the slider 221, thereby increasing the flexibility of the clamping position of the clamping device 4. By setting a positioning member 23 and a positioning hole 2211 that cooperates with the positioning member 23, the clamping device can be conveniently fixed on the guide rail 21.

[0030] The number of the guide rails 21 is the same as the number of the sliders 221 , and the number may be one or more, and the guide rails 21 and the sliders 221 are arranged in a one-to-one correspondence.

[0031] In a specific implementation scenario, there are two guide rails 21, which are arranged in parallel and fixed on the base 1. There are two sliders 221, which are arranged on the two guide rails 21, and the two sliders 221 are arranged opposite to each other and connected to the carrier 222. A positioning hole 2211 is provided on each of the two sliders 221, and the positioning hole 2211 is provided on the outer side of the two sliders 221. The outer side of the two sliders 221 is specifically the side of one slider 221 facing away from the other slider 221.

[0032] The arrangement of the plurality of guide rails 21 and the plurality of sliders 221 provides the carrier plate 222 with a plurality of supporting points, thereby improving the stability of the connection structure between the carrier plate 222 and the sliders 221 .

[0033] The clamping device 4 includes a linear transmission mechanism 42 and a clamping mechanism 43 .

[0034] The linear transmission mechanism 42 includes a bidirectional screw rod 421, a first transmission member 422, a second transmission member 423 and a fixing member 424;

[0035] like Figure 3As shown, the fixing member 424 includes a base 4241, a first fixing portion 4242, a second fixing portion 4243 and a transmission slide rail 4244. The base 4241 is fixed to the loading plate 222 by bolts. The first fixing portion 4242 and the second fixing portion 4243 are respectively arranged on both sides of the base 4241 and are arranged opposite to each other. The transmission slide rail 4244 is fixed to the base 4241, with one end facing the first fixing portion 4242 and the other end facing the second fixing portion 4243.

[0036] The output end of the bidirectional screw rod 421 is slidably connected to the first fixed part 4242, and the end opposite to the output end is slidably connected to the second fixed part 4243. The first fixed part 4242 is equipped with a motor or a handle. Specifically, a motor is installed in the first fixed part 4242, and the motor is connected to the output end of the bidirectional screw rod 421 for driving the bidirectional screw rod 421 to rotate axially.

[0037] The first transmission member 422 is a first nut, and the first nut is provided with a first sliding groove. The second transmission member 423 is a second nut, and the second nut is provided with a second sliding groove.

[0038] The thread directions of the first nut and the second nut are opposite. The first nut and the second nut are passed through and threadedly connected to the bidirectional screw rod 421. The first nut is slidably connected to the transmission slide rail 4244 through the first slide groove, and the second nut is slidably connected to the transmission slide rail 4244 through the second slide groove. When the bidirectional screw rod 421 rotates, the first nut and the second nut move in a straight line, and the directions of their movement are opposite.

[0039] The clamping mechanism 43 includes a first clamping member 431 and a second clamping member 432. The first clamping member 431 is a first clamping plate, which is fixed on the first nut. The second clamping member 432 is a second clamping plate, which is fixed on the second nut. The first clamping block is provided with a first groove body 411, and the second clamping block is provided with a second groove body 412. The first clamping block and the second clamping block are connected to each other through the movement of the first nut and the second nut, so as to form a clamping groove 41.

[0040] The shape of the clamping groove 41 matches the shape of the part to be clamped.

[0041] In a specific implementation scenario, the part to be clamped is a cylindrical barrel, the clamping groove 41 is a cylindrical structure, and the first groove body 411 and the second groove body 412 are semi-cylindrical structures.

[0042] By setting the first clamping member 431, the second clamping member 432, the bidirectional screw 421, the first transmission member 422 and the second transmission member 423, the screw threads of the first transmission member 422 and the second transmission member 423 are in opposite directions, so that the first clamping member 431 and the second clamping member 432 are respectively moved in different directions of the bidirectional screw through the first transmission member 422 and the second transmission member 423, thereby clamping and releasing the cylinder body, and setting a clamping groove 41 that matches the cylinder body to achieve better clamping effect and prevent the cylinder body from loosening.

[0043] The abutting device 3 includes two mounting plates 32 , two abutting posts 31 , two abutting blocks 33 and two flexible members 34 .

[0044] The two mounting plates 32 are disposed at both ends of the guide rail 21 and are opposite to each other. They are fixed to the base 1 by screws. The two mounting plates 32 are respectively provided with through holes 321 . The two through holes 321 are opposite to each other, and screw nuts 35 are respectively passed through and fixed in the two through holes 321 .

[0045] The two abutment columns 31 can be two one-way screw rods, which are respectively slidably connected to the two screw nuts 35. The two one-way screw rods are opposite to each other and are coaxially arranged with the clamping groove 41. The output ends of the two one-way screw rods are connected to two motors or two handles. Specifically, the output ends of the two one-way screw rods are connected to two handles.

[0046] The two abutment blocks 33 are two rigid blocks, which may be two iron blocks. The two iron blocks are respectively arranged at one end of the two one-way screws facing the clamping groove 41 to increase the abutment area and enhance the abutment stability.

[0047] The two flexible members 34 can be two rubber columns, which are arranged at one end of the two iron blocks facing the clamping groove 41. The size of the rubber columns is not less than that of the iron blocks, and is used to protect the abutted parts from deformation due to inappropriate abutment force when being abutted.

[0048] In a specific implementation scenario, the parts to be abutted include a top cover and a bottom cover, two iron blocks and two rubber columns are respectively abutted to the middle of the top cover and the bottom cover, and the top cover and the bottom cover are abutted to the two ends of the cylinder, so that the top cover, the bottom cover and the cylinder are coaxially arranged.

[0049] The steps for using the clamp disclosed in the present invention are as follows:

[0050] In the first step, the operator pushes the clamping device 4 to move to a suitable position along the guide rail 21;

[0051] In the second step, the operator operates the motor or the handle to rotate the bidirectional screw rod 421 in a direction to separate the first nut from the second nut;

[0052] In the third step, the operator inserts the cylinder into the clamping groove 41 and adjusts the clamping position;

[0053] In the fourth step, the operator operates the motor connected to the bidirectional screw rod 421 to rotate the bidirectional screw rod 421 in a direction to make the first nut and the second nut approach each other, thereby completing the clamping of the cylinder;

[0054] Step 5: After the cylinder has been stably clamped by the clamping device 4, the operator first operates the top cover or the bottom cover;

[0055] Step 6: When operating the top cover, align it with one end of the cylinder, and then operate the handle connected to the one-way screw to rotate the one-way screw, push the iron block and rubber column to move in a straight line, and abut against the top cover.

[0056] Step 7. Connect the bottom cover to the other end of the cylinder in the same manner as step 6.

[0057] The clamp provided by the present invention clamps the cylinder while abutting the top cover and the bottom cover against the two ends of the cylinder, so that the top cover, the cylinder and the bottom cover are coaxially arranged, which increases the stability of clamping, makes the target device difficult to move, and facilitates welding, thereby improving the yield of subsequent operations.

[0058] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of this disclosure can be achieved, and this document is not limited here.

[0059] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0060] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
