Description

Technical Field

[0001] The utility model relates to the technical field of symmetry detection devices, in particular to a symmetry detection device for petroleum machinery parts. Background Art

[0002] Petroleum machinery refers to mechanical devices used in oilfield exploitation, such as drilling rig derricks, and drilling rig derrick parts mainly include main frame, base, drill pipe, drill pipe retractor, turntable, drill plug, mud pump and pipeline system. It is mainly used for drilling operations in oil wells.

[0003] Existing symmetry detection devices for petroleum machinery parts use a ruler for manual measurement, or use a clamp to fix the two sides for comparison. Manual comparison with a ruler may result in measurement deviations because it is difficult to ensure the horizontality of the viewing angle. The method of clamping and comparing on both sides makes it difficult to define the detection center position of the parts. Directly pushing by clamping will cause displacement deviations in the parts, making it difficult to determine whether the parts are symmetrical, so that the plates on both sides can fit the surface of the parts well, and the detection is not accurate enough, affecting the accuracy of the detection results.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a symmetry detection device for petroleum machinery parts is proposed. Utility Model Content

[0005] The utility model aims to provide a symmetry detection device for petroleum machinery parts to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a symmetry detection device for petroleum machinery parts, comprising a workbench, a mounting plate is fixedly arranged above the surface of the workbench, four sinking grooves are evenly distributed on the surface of the mounting plate, a clamping piece is arranged inside the sinking groove, and a movable rod is arranged on the surface of the clamping piece.

[0007] Preferably, the clamping member includes a screw rod rotatably mounted on the inner surface of the groove, a moving block is threadedly connected to the surface of the screw rod, the moving block is slidably fitted to the inner surface of the groove, and a thrust plate is fixedly provided on the upper end of the moving block.

[0008] Preferably, the clamping member also includes a driven gear with one end in the middle of the screw rod passing through the recessed groove and fixedly installed, a driving gear is meshedly arranged below the surface of the driven gear, and the driving gear is rotatably connected to the middle of the inner surface of the mounting plate.

[0009] Preferably, the clamping member also includes a driving motor installed on the mounting plate through a connecting rod at the lower end of the driving gear, and the driving motor is fixedly connected to the middle portion below the outer surface of the mounting plate.

[0010] Preferably, the movable rod slides through the middle of the surface of the propulsion plate, and a spring is fixedly installed on one end of the movable rod close to the outer side.

[0011] Preferably, one end of the spring is fixedly connected to the outer surface of the propulsion plate, and scale lines are provided on the surface of the movable rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a sink, a clamping piece, a screw rod, a moving block, a driven gear, a driving gear, a driving motor and a pushing plate. The driving motor drives the driving gear to rotate, thereby engaging four driven gears to drive four screw rods to rotate at the same frequency. Under the limit of the sink, the moving block is subjected to the thread pushing force of the screw rod, which will drive the pushing plate to move synchronously to the middle to clamp the parts to be inspected. Moreover, since the four pushing plates can move synchronously, the pushing plates can ensure that the symmetrical parts are completely centered. If a corresponding pushing plate has a deviation on the left or right, or the clamped part is not in the middle of the mounting plate, it can be judged that the two sides of the part are not symmetrical, the detection accuracy is high, and it is convenient for manual judgment.

[0014] 2. The utility model arranges movable rods, springs and scale lines. When the push plate squeezes the parts, the movable rods will contact the parts first, so that the movable rods push the tension springs. If the parts are completely symmetrical, all the movable rods will have the same extension amount after the push plate clamps them. If the parts are asymmetrical, the extension amount of the movable rods that fit the surface of the parts using the elastic force of the springs will be different depending on the position of the push plate away from the parts. At this time, the difference between the two ends of the symmetrical position can be accurately judged according to the scale lines, thereby making precise adjustments, which is further convenient for manual judgment and processing.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 4 As shown, a symmetry detection device for petroleum machinery parts includes a workbench 1, a mounting plate 2 is fixedly arranged on the surface of the workbench 1, four sinking grooves 3 are evenly distributed on the surface of the mounting plate 2, a clamping member 4 is arranged inside the sinking groove 3, and a movable rod 5 is arranged on the surface of the clamping member 4.

[0022] Furthermore, the clamping member 4 includes a screw rod 401 rotatably installed on the inner surface of the groove 3, and a moving block 402 is threadedly connected to the surface of the screw rod 401. The moving block 402 slides and fits the inner surface of the groove 3, and a thrust plate 406 is fixedly provided on the upper end of the moving block 402.

[0023] By adopting the above technical solution, the sink 3 limits the moving block 402, so that when the screw rod 401 rotates, the moving block 402 can stably drive the propulsion plate 406 to adjust.

[0024] Furthermore, the clamping member 4 also includes a driven gear 403 which is fixedly installed at one end of the middle part of the screw rod 401 and passes through the sink groove 3. A driving gear 404 is meshedly arranged under the surface of the driven gear 403, and the driving gear 404 is rotatably connected to the middle part of the inner surface of the mounting plate 2.

[0025] By adopting the above technical solution, the driving gear 404 can synchronously drive the four driven gears 403 to rotate, so that the four screw rods 401 rotate at the same frequency and speed, and the moving block 402 can drive the propulsion plate 406 to move synchronously.

[0026] Furthermore, the clamping member 4 also includes a driving motor 405 installed on the mounting plate 2 through a connecting rod at the lower end of the driving gear 404 , and the driving motor 405 is fixedly connected to the middle part below the outer surface of the mounting plate 2 .

[0027] By adopting the above technical solution, the driving motor 405 provides rotational force for the driving gear 404 .

[0028] Furthermore, the movable rod 5 slides through the middle of the surface of the pushing plate 406 , and a spring 6 is fixedly installed at one end of the movable rod 5 close to the outer side.

[0029] By adopting the above technical solution, the spring 6 pulls the movable rod 5 to always maintain a protruding state toward the middle of the mounting plate 2; when the push plate 406 squeezes the parts, the movable rod 5 will preferentially contact the parts, so that the movable rod 5 pushes the tension spring 6. If the parts are completely symmetrical, then after the push plate 406 clamps, the extension amount of all the movable rods 5 is the same. If the parts are asymmetrical, the extension amount of the movable rod 5 using the elastic force of the spring 6 will be different depending on the distance of the push plate 406.

[0030] Furthermore, one end of the spring 6 is fixedly connected to the outer surface of the pushing plate 406 , and a scale line 7 is provided on the surface of the movable rod 5 .

[0031] By adopting the above technical solution, the difference between the two ends of the asymmetric position can be accurately determined according to the scale line 7.

[0032] Working principle: When using the symmetry detection device for petroleum machinery parts, first, place the part to be tested in the middle of the mounting plate 2, then drive the motor 405 to drive the active gear 404 to rotate, thereby engaging the four driven gears 403 to drive the four screw rods 401 to rotate at the same frequency. Under the limit of the sink 3, the moving block 402 is subjected to the thread pushing force of the screw rod 401, which will drive the push plate 406 to move synchronously to the middle to clamp the part to be tested. When the push plate 406 squeezes the part, the movable rod 5 will contact the part first, so that the movable rod 5 pushes the tension spring 6. Since the four push plates 406 can move synchronously, the push plates 406 can ensure that the symmetrical parts are completely clamped in the center. If a corresponding push plate 406 deviates to the left or right, or the clamped part is not in the middle of the mounting plate 2, it can be judged that the two sides of the part are not symmetrical. If the part is completely symmetrical, then after the push plate 406 clamps, the extension amount of all movable rods 5 is the same. If the part is asymmetrical, according to the position of the push plate 406 away from the part, the extension amount of the movable rod 5 that fits the surface of the part using the elastic force of the spring 6 is different. At this time, the difference between the two ends of the symmetrical position can be accurately judged according to the scale line 7, so as to make precise adjustments. This is the working principle of the symmetry detection device for petroleum machinery parts.
