Description

Technical Field

[0001] The utility model relates to the technical field of sucker rod couplings, in particular to a special tooling equipment for milling and clamping of sucker rod couplings. Background Art

[0002] The standards of sucker rod couplings mainly include aspects such as dimensional specifications, material selection, anti-adhesion treatment, etc. Dimensional specifications: Sucker rod couplings are divided into ordinary couplings and reducing couplings. The ordinary coupling has the same internal thread size at each end and is used to connect sucker rods or short rods, or heavy rods with sucker rod threads. The reducing coupling has different internal thread sizes at each end and is used to connect two sizes of sucker rods or a polished rod to the sucker rod string. The dimensions should meet specific table and drawing requirements. Material selection: According to requirements, the performance grade should meet grade T. Anti-adhesion treatment: According to the contract requirements, an anti-adhesion coating is applied to the threads of the coupling and reducing coupling to reduce the anti-adhesion tendency when the coupling is screwed with the sucker rod, short rod or polished rod. The anti-adhesion treatment should not affect the final allowable dimensional requirements. In addition, sucker rod couplings also involve other technical indicators, such as product model specifications, structural types (standard couplings, arc couplings, external flow channel couplings, internal flow channel couplings, and comprehensive flow channel couplings, etc.), as well as regulations on non-destructive testing, personnel qualification identification and certification, etc. These standards ensure the quality and performance of sucker rod couplings to meet the requirements during oil extraction.

[0003] When the existing special tooling equipment for milling and clamping is in use, such as a special tooling equipment for milling and clamping of sucker rod couplings with the application number CN202020976880.7, which includes a bottom plate. The bottom plate is inclined backward. Support rods are respectively and fixedly installed on the left and right sides of the top surface of the bottom plate. A cross block is fixedly installed on the top surface of the support rods. A first groove is opened on the bottom surface of the cross block. A first through groove is opened in the middle of the top surface of the inner wall of the first groove. Second grooves are respectively opened on the upper sides of the front and rear inner walls of the first groove. One sides of several movable plates are respectively and movably installed in the second grooves on the front and rear sides. The outer peripheries of the movable plates are respectively in sliding contact and cooperation with the inner walls of the corresponding second grooves. However, in the above technology, the clamping is mainly carried out through the second grooves. Since it is a group, it will cause the product to be misaligned during the clamping process, affecting subsequent processing. Therefore, the utility model proposes a special tooling equipment for milling and clamping of sucker rod couplings to solve the problems existing in the prior art. Content of the Utility Model

[0018] In order to deepen the understanding of the present utility model, the following will further describe the present utility model in detail with reference to the embodiments. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0019] According to Figures 1-3 as shown, this embodiment proposes a special tooling equipment for milling and clamping of sucker rod couplings, including a shock-absorbing support assembly 1 and a clamping mechanism 3. Above the middle of the shock-absorbing support assembly 1, a tensioning and loosening adjustment component 2 assembled with bolts is provided. Inside the shock-absorbing support assembly 1 and the tensioning and loosening adjustment component 2, a clamping mechanism 3 is provided, and inside the clamping mechanism 3, a sucker rod coupling body 4 is provided;

[0020] The clamping mechanism 3 includes a pneumatic telescopic arm 301, a hinge group base 302, an extension rod 303, a side pressing piece 304, a hinge base 305, and an end pressing piece 306. The pneumatic telescopic arm 301 is arranged on the inner end side of the tightening adjustment component 2. Hinge group bases 302 are arranged at both ends of the pneumatic telescopic arm 301, and extension rods 303 are arranged on the side of the hinge group base 302. A side pressing piece 304 is arranged on the inner side of the extension rod 303. A hinge base 305 is arranged at one end of the extension rod 303, and an end pressing piece 306 is arranged on the inner side of the hinge base 305.

[0021] The side pressing piece 304 and the end pressing piece 306 are in a circular convex structure, and the extension rods 303 are symmetrically distributed with respect to the central axis of the hinge base 305.

[0022] In this embodiment, when the through strip 209 is pulled, the output end of the pneumatic telescopic arm 301 outputs power to drive the output end to perform telescopic operation, and then the hinge transmission operations of the hinge group base 302, the extension rod 303, and the hinge base 305 are carried out, so that the side pressing piece 304 on the inner side of the extension rod 303 and the end pressing piece 306 on the inner side of the hinge base 305 clamp and position the sucker rod coupling body 4 to be processed, facilitating the user's processing operation.

[0023] The shock absorption support assembly 1 includes a cushion block 101, a base table 102, a bolt substrate 103, an end plate 104, a first shock absorber 105, a shock absorption plate 106, and a second shock absorber 107. The base table 102 is arranged on the top side of the cushion block 101, and bolt substrates 103 assembled by bolts are arranged above both ends of the base table 102. The end plate 104 is arranged on the top side of the bolt substrate 103.

[0024] In this embodiment, when in use, after the device is placed at the processing location through the cushion block 101, the end plate 104 is bolted by using the bolt substrate 103 above both ends of the base table 102, so that the sucker rod coupling body 4 to be processed needs to be placed in the inner space of the clamping mechanism 3.

[0025] A first shock absorber 105 is arranged on the inner side of the end plate 104, a shock absorption plate 106 is arranged at the inner end of the first shock absorber 105, and a second shock absorber 107 is arranged on the inner side of the shock absorption plate 106.

[0026] In this embodiment, since the second shock absorbers 107 and the first shock absorbers 105 are arranged in an array on both side edges of the shock absorption plate 106, when the product is processed, the shock absorption effect can be effectively achieved.

[0027] The tightening adjustment component 2 includes a motor base 201, a driving motor 202, a rotating shaft 203, a driving gear 204, a rack 205, a spacer 206, a connecting rod 207, a pressing plate 208, and a through bar 209. The motor base 201 is bolted above the middle of the base table 102. The driving motor 202 is arranged above the periphery of the motor base 201, and the output end of the driving motor 202 is provided with the rotating shaft 203, and the output end of the rotating shaft 203 is provided with the driving gear 204.

[0028] In this embodiment, when it is necessary to clamp the sucker rod coupling body 4 to be processed, the driving motor 202 above the periphery of the motor base 201 outputs power to drive the output end to operate. After the driving motor 202 outputs power, it can drive the rotating shaft 203 to rotate. When the rotating shaft 203 rotates, it can drive the driving gear 204 to rotate.

[0029] A rack 205 is arranged on one side of the driving gear 204, a connecting rod 207 is arranged above the rack 205, a pressing plate 208 assembled by bolts is arranged on one end side of the connecting rod 207, and a through bar 209 penetrating and connecting with the spacer 206 is arranged on one side of the pressing plate 208.

[0030] In this embodiment, when the driving gear 204 rotates, it can drive the rack 205 to engage and transmit power. After the rack 205 engages and transmits power, the rack 205 exerts force on the connecting rod 207, causing the pressing plate 208 to drive the through bar 209 to contract.

[0031] The working principle of the special tooling equipment applied to the milling and clamping of sucker rod collars is as follows: When in use, the equipment is placed at the processing site through the spacer block 101. Then, the end plate 104 is bolted to the two ends above the base table 102 using the bolt substrate 103. The sucker rod collar body 4 to be processed is placed in the inner space of the clamping mechanism 3. Since both side edges of the shock-absorbing plate 106 are equipped with the second shock absorbers 107 and the first shock absorbers 105 distributed in an array, when the product is being processed, an effective shock-absorbing effect can be achieved. When it is necessary to clamp the sucker rod collar body 4 to be processed, the driving motor 202 above the periphery of the motor base 201 outputs power to drive the output end to operate. After the driving motor 202 outputs power, it can drive the rotating shaft 203 to rotate. When the rotating shaft 203 rotates, it can drive the driving gear 204 to rotate. When the driving gear 204 rotates, it can drive the rack 205 to engage in transmission. After the rack 205 engages in transmission, the rack 205 exerts force on the connecting rod 207, causing the pressure plate 208 to drive the through bar 209 to contract. When the through bar 209 is pulled, the output end of the pneumatic telescopic arm 301 outputs power to drive the output end to expand and contract. After the hinge transmission of the hinge group seat 302, the extension rod 303, and the hinge base 305, the side pressure piece 304 on the inner side of the extension rod 303 and the end pressure piece 306 on the inner side of the hinge base 305 clamp and position the sucker rod collar body 4 to be processed for the user to perform processing operations.
