Description

Technical Field

[0001] The present application relates to the technical field of posting devices, and in particular to a cemented carbide block posting device. Background Art

[0002] TC bearings can also be called carbide bearings and radial bearings. TC bearings are divided into inner and outer bearing sleeves. The inner sleeve is matched and locked with the transmission shaft, and the outer sleeve is assembled with the downhole power drill housing. The two cooperate to form a working surface. The main function is to transmit the torque and speed of the motor to the drill bit. During operation, the TC bearing is subjected to axial and radial forces from the universal bearing and the drill bit, and the inner sleeve has a tendency to move eccentrically around the outer sleeve. The normal failure form of TC bearings is cylindrical layer wear. Due to the long-term erosion of sand-containing well fluid, it is required to have good wear resistance and corrosion resistance.

[0003] In order to make the outer wall of the TC bearing have better wear resistance, a method of adding a carbide block to the outer sleeve of the TC bearing is often used in the production process of TC bearings. Generally, the carbide block is first pasted on a sticker, and then the carbide block sticker is manually pasted to the outer sleeve of the TC bearing. After that, the whole is sintered so that the carbide block is completely adhered to the outer sleeve of the TC bearing, thereby increasing the wear resistance of the TC bearing.

[0004] With respect to the above-mentioned related technologies, the inventors believe that manually sticking stickers with carbide blocks attached to the outer sleeve of the TC bearing is laborious because workers need to repeat the same work over a long period of production and need to concentrate. Summary of the invention

[0005] The purpose of the present application is to provide a cemented carbide block pasting device which is convenient for pasting a cemented carbide block sticker onto an outer sleeve of a TC bearing.

[0006] The present application provides a cemented carbide block pasting device that adopts the following technical solution:

[0007] A cemented carbide block pasting device comprises a conveying component for conveying the cemented carbide block sticker, a pasting component for driving the TC bearing to be pasted with the sticker is provided on one side of the conveying component, a storage component for storing the TC bearing is provided on one side of the pasting component, and a discharging component for removing the pasted TC bearing from the pasting component is provided on one side of the conveying component.

[0008] By adopting the above technical solution, a sticker with a carbide block attached to one side is placed on the conveying component, then one side of the carbide block is facing the conveying component, glue is applied to the other side of the sticker, and then the sticker is attached to the TC bearing through the pasting component, and the TC bearing is stored in the storage component, which can reduce the trouble of placing the TC bearings repeatedly in succession. The automatic unloading of the device can be realized through the cooperation of the pasting component and the unloading component, which reduces the trouble of operation for the staff and alleviates the workload of the staff.

[0009] Optionally, the conveying component includes an active roller, a conveyor belt motor for driving the active roller to rotate is provided at one end of the active roller, a driven roller is provided on one side of the active roller, a conveyor belt connecting the active roller and the driven roller is provided on the outer sides of the active roller and the driven roller, the active roller and the driven roller are located at both ends of the conveyor belt, the sticker is placed on the conveyor belt, and a conveyor belt bracket for supporting the conveyor belt is provided on one side of the conveyor belt.

[0010] By adopting the above technical solution, the stickers are transferred through the conveyor belt, so that the stickers can be continuously transferred, thereby achieving the effect of continuously adhering the stickers on the TC bearing, thereby increasing the efficiency of pasting the stickers on the TC bearing.

[0011] Optionally, the pasting assembly includes a material receiving rod located above the conveyor belt, one end of the material receiving rod is fixedly provided with a positioning plate, one end of the material receiving rod passes through the positioning plate and is connected to a rotating motor, a limiting plate is also slidably sleeved on the material receiving rod, a plurality of push rods are fixedly connected to the side of the positioning plate close to the limiting plate, and the side of the push rod away from the positioning plate abuts against the limiting plate.

[0012] By adopting the above technical solution, when it is necessary to paste the carbide block sticker on the TC bearing, the TC bearing is firstly mounted on the receiving rod, and then the TC bearing rotates driven by the sticker and the conveyor belt, so as to realize the pasting of the sticker, reducing the trouble of manually pasting the carbide block sticker. At the same time, the synergistic effect of the limit plate and the push rod can make the TC bearing located in the correct position of the receiving rod, thereby reducing the occurrence of the phenomenon that the TC bearing and the sticker position are offset and the sticker position is skewed.

[0013] Optionally, a side of the material receiving rod away from the positioning plate is configured to be conical.

[0014] By adopting the above technical solution, when it is necessary to sleeve the TC bearing on the material receiving rod, since one end of the material receiving rod is conical, the TC bearing can be better sleeved on the material receiving rod, thereby speeding up the efficiency of sleeve-mounting the TC bearing.

[0015] Optionally, the material storage assembly includes a first material storage platform, which is inclined and gradually inclined downward from an end away from the conveying assembly to an end close to the conveying assembly, and a second material storage platform is fixedly connected to an end of the first material storage platform close to the conveyor belt, and the second material storage platform is located on a side of the first material storage platform close to the conveyor belt below the first material storage platform, and a first baffle and a second baffle are fixedly connected on both sides of the first material storage platform and the second material storage platform, respectively, and an end of the second material storage platform away from the first material storage platform faces the material receiving rod.

[0016] By adopting the above technical solution, when it is necessary to affix carbide block stickers to the outer side of a TC bearing, a plurality of TC bearings are first placed on the first material storage platform, and the axis of the TC bearing is parallel to the center line of the material receiving rod. When necessary, the TC bearing slides from the first material storage platform to the second material storage platform, and then the TC bearing on the second material storage platform is sleeved on the material receiving rod, so that continuous sleeve connection of the TC bearings can be achieved, thereby further accelerating the overall work efficiency of affixing carbide blocks on TC bearings.

[0017] Optionally, a pushing block is further provided on the second material storage platform, one side of the pushing block is rotatably connected to a pushing rod, a torsion spring connecting the pushing block and the pushing rod is provided at the connection between the two, and a pushing hydraulic cylinder for driving the pushing block to move is installed on the pushing rod.

[0018] By adopting the above technical solution, when the TC bearing needs to be sleeved on the material receiving rod from the second material storage platform, the pushing hydraulic cylinder is started, and the pushing hydraulic cylinder drives the pushing rod and the pushing block to move to the side close to the material receiving rod. While moving, the pushing rod pushes the TC bearing and sleeves the TC bearing on the material receiving rod. Then, a carbide block sticker is affixed to the outer side of the TC bearing. Then, the pushing hydraulic cylinder moves to the side away from the bearing. At the same time, when the pushing block moves to the side of the next TC bearing close to the first material storage platform, it rotates to a vertical state under the action of the torsion spring to push the next TC bearing, thereby reducing the labor cost required for sleeve TC bearings and reducing the work intensity of the staff when sleeve TC bearings.

[0019] Optionally, the unloading assembly includes a plurality of tension springs located between the positioning plate and the limiting plate for connecting the two. A unloading support rod is provided on one side of the conveyor belt, and a plurality of arc-shaped unloading rods are fixedly connected to one end of the unloading support rod.

At the same time, the side of the limit plate away from the TC bearing abuts against the arc-shaped unloading rod, so that the TC bearing falls off the receiving rod during the rotation process, thereby achieving two effects of the limit plate. On the one hand, the limit plate can limit the TC bearing so that it is in an appropriate position to paste the carbide block sticker. On the other hand, the limit plate can cooperate with the unloading rod to realize the unloading operation of the TC bearing, and reduce the labor cost required for the entire pasting process.

[0021] Optionally, a material receiving box for receiving the TC bearing is provided at one end of the unloading rod away from the conveyor belt.

[0022] By adopting the above technical solution, after the TC bearing falls off from the receiving rod, the TC bearing falls into the receiving box, which reduces the trouble of the staff in collecting the TC bearing.

[0023] Optionally, a flexible cushion layer is fixedly connected to the inner wall of the material receiving box.

[0024] By adopting the above technical solution, the flexible cushion layer can reduce the possibility of damage to the TC bearing when the TC bearing falls into the inside of the material receiving box.

Second baffles 221 are fixedly connected to both sides of the second material storage platform 22, and the end of the second material storage platform 22 away from the connecting plate 222 faces the material receiving rod 31.

[0042] A plurality of support rods 231 are fixedly connected to one side of the first material storage platform 21 close to the ground, a first material storage support 23 is fixedly connected to one end of the support rod 231 away from the first material storage platform 21, a second material storage support 232 is fixedly connected to one side of the second material storage platform 22 close to the ground, and the first material storage support 23 and the second material storage support 232 are installed on the ground at one end away from the first material storage platform 21 or the second material storage platform 22.

[0043] A pushing block 24 is provided on the side of the second material storage platform 22 away from the second material storage bracket 232. The shape of the pushing block 24 can be of various shapes. In the present device, it is preferably a triangular prism with a right-angled triangle cross-section. One side of the pushing block 24 abuts against the side of the second material storage platform 22 away from the second material storage bracket 232. A pushing rod 241 is provided on one side of the pushing block 24. The end of the pushing rod 241 close to the pushing block 24 passes through the pushing block 24 and is rotatably connected to the pushing block 24. A torsion spring 2411 connecting the pushing rod 241 and the pushing block 24 is installed at the connection between the pushing rod 241 and the pushing block 24, and the side of the pushing block 24 close to the receiving rod 31 is set as a plane perpendicular to the second material storage platform 22, and the side of the pushing block 24 away from the receiving rod 31 is set as an inclined surface that gradually inclines from one end close to the second material storage platform 22 to one end away from the second material storage platform 22 to one end close to the first material storage platform 21.

[0045] When it is necessary to install a TC bearing on the material receiving rod 31, it is only necessary to place multiple TC bearings on the first material storage platform 21. During the placement process, the axis of the TC bearing is parallel to the axis of the material receiving rod 31. Then the TC bearing slides along the first material storage platform 21 to the second material storage platform 22. Then, the pushing hydraulic cylinder 25 is started, and the pushing hydraulic cylinder 25 pushes the pushing rod 241. The pushing rod 241 pushes the pushing block 24. The pushing block 24 pushes the TC bearing located on the second material storage platform 22 to move to the side close to the material receiving rod 31. Then, the TC bearing is installed on the material receiving rod 31.

[0046] Afterwards, when the pushing hydraulic cylinder 25 drives the pushing block 24 to move toward the side close to the connecting plate 222, the inclined surface of the pushing block 24 contacts the TC bearing, and one end of the TC bearing abuts against one side of the connecting plate 222, thereby causing the pushing block 24 to rotate. At the same time, due to the presence of the torsion spring 2411, when the pushing block 24 moves between the TC bearing and the connecting plate 222, the pushing block 24 is inserted into the gap between the TC bearing and the connecting plate 222, pushing the subsequent TC bearing again, thereby realizing the continuous operation of the TC bearing sleeved on the connecting rod 31. At the same time, the TC bearing located on the connecting rod 31 can be located at an appropriate position of the conveyor belt 13 under the limiting action of the push rod 3112 and the limiting plate 311.

[0047] Reference Figure 1 and Figure 3 A feeding assembly 4 is also provided on the side of the conveyor belt 13 close to the pasting assembly 3.

[0048] A material discharge rod 42 is also provided on one side of the material receiving rod 31. The material discharge rod 42 is arranged in an arc shape. Two material discharge rods 42 are arranged in parallel and are parallel to the conveyor belt 13. The two material discharge rods 42 are located on the upper and lower sides of the material receiving rod 31. The ends of the two material discharge rods 42 away from the conveyor belt 13 are fixedly connected with a material discharge support rod 421 for connecting the two. The end of the material discharge support rod 421 away from the material discharge rod 42 is installed on the ground.

[0049] The outer arc surface of the feeding rod 42 close to the conveyor belt 13 abuts against the side of the limit plate 311 close to the positioning plate 3111, and a material receiving box 43 is provided below the end of the feeding rod 42 away from the conveyor belt 13. The side of the material receiving box 43 close to the feeding rod 42 is provided with an opening for receiving the fallen TC bearing, and the inner wall of the material receiving box 43 is fixedly connected with a flexible cushion layer 431.

[0050] After the TC bearing on the receiving rod 31 is pasted with the sticker, the rotating motor 32 drives the receiving rod 31 to rotate. During the rotation of the receiving rod 31, the lowering rods 42 on both sides of the receiving rod 31 gradually push the limit plate 311 to the side away from the positioning plate 3111, so that the TC bearing above the receiving rod 31 falls into the receiving box 43. Then, the rotating motor 32 drives the receiving rod 31 to rotate in the opposite direction to the top of the conveyor belt 13, and the limit plate 311 moves to the position of contact with the top rod 3112 driven by the tension spring 41.

[0051] The implementation principle of the embodiment of the present application is: first, the TC bearing is placed on the first material storage platform 21, and then the TC bearing on the first material storage platform 21 slides to the second material storage platform 22, and the pushing hydraulic cylinder 25 is started. The pushing hydraulic cylinder 25 drives the pushing block 24 to continuously push the TC bearing onto the material receiving rod 31, and at the same time, the push rod 3112 and the limit plate 311 on the material receiving rod 31 realize the limitation of the TC bearing on the connecting material rod 31.

[0052] The TC bearing on the receiving rod 31 rotates under the drive of the hard alloy block sticker and the conveyor belt 13, so that the hard alloy block sticker is pasted on the TC bearing.

[0053] Afterwards, the receiving rod 31 rotates driven by the rotating motor 32, and through the cooperation between the unloading rod 42 and the limiting plate 311, the TC bearing above the receiving rod 31 can fall into the receiving box 43 when the rotating motor 32 drives the receiving rod 31 to rotate.
