Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to a piston shaft locking device. Background Technology

[0002] For linear piston motors, a lead screw and nut assembly is installed inside the motor body. The piston shaft and the lead screw and nut are generally locked by a threaded connection. In production, the connection between the lead screw and nut assembly, the piston shaft and the motor body is generally done manually. This not only results in low production efficiency and high manpower consumption, but also poor installation consistency, which affects product quality.

[0003] Currently, there are some devices on the market that automatically tighten piston shafts, but they have poor adaptability. They may not be able to be installed properly or may be incompatible with different models of linear piston motors.

[0004] Therefore, a piston shaft locking device is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

The transverse mechanism can drive the support base to move in the horizontal direction, so as to move the support base between the piston shaft station and the dust removal station.

[0031] The beneficial effects of this invention are as follows:

[0032] The piston shaft locking device provided by this invention installs the piston shaft via an upper screwing mechanism and the lead screw nut assembly via a lower screwing mechanism. After the motor, piston shaft, and lead screw nut assembly are inserted, the lower pressing assembly presses the motor against the support base from above. The rotating mold head of the limiting clamping assembly extends into the motor and engages with the rotor to prevent the rotor and lead screw nut from rotating. Simultaneously, the upper bit is inserted into the screwing groove at the upper end of the piston shaft. Then, the upper pushing assembly drives the lower screwing assembly to rise, causing the lower bit to press against the locking screw of the lead screw. The lower screwing assembly tightens the locking screw to complete the lower end locking installation of the lead screw nut assembly. Then, the upper screwing assembly drives the piston shaft to rotate so that it is screwed onto the lead screw nut, thereby achieving automatic locking installation of the piston shaft.

[0051] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] like Figures 1-6 As shown, this embodiment provides a piston shaft locking device for locking the lead screw nut assembly and piston shaft into a motor to assemble a linear piston motor. The piston shaft locking device includes a base and mounted on the base: a support 90, an upper tightening mechanism, a lower tightening mechanism, a dust removal mechanism 60, and a transverse movement mechanism 70. The support 90 supports the motor and defines its position. The base has a piston shaft locking station and a dust removal station. The transverse movement mechanism 70 moves the support 90 horizontally, transferring it between the piston shaft locking station and the dust removal station. At the piston shaft locking station, the upper tightening mechanism and the lower tightening mechanism respectively lock the piston shaft and the lead screw nut assembly; at the dust removal station, the dust removal mechanism 60 cleans the motor's internal cavity by blowing and suction.

[0053] Furthermore, such as Figures 1-5 As shown, the upper screwing mechanism includes a lower pressing component 10, an upper screwing component 20, and a limiting and clamping component 30. Both the upper screwing component 20 and the limiting and clamping component 30 are mounted on the output end of the lower pressing component 10. The lower pressing component 10 can press against the motor from above and drive the upper screwing component 20 and the limiting and clamping component 30 to rise and fall. The upper screwing component 20 is used to screw the piston shaft and includes an upper bit 21, which moves vertically. The limiting and clamping component 30 includes a detachably mounted rotating mold. The tool head 31 is elastically connected to the movable end of the pressing assembly 10 in the vertical direction. The rotating tool head 31 can extend into the motor and engage with the rotor. The lower turning mechanism includes an upper lifting assembly 40 and a lower turning assembly 50. The lower turning assembly 50 is installed at the output end of the upper lifting assembly 40. The upper lifting assembly 40 can drive the lower turning assembly 50 to rise and fall. The lower turning assembly 50 is used to turn the locking screw of the lead screw. The lower turning assembly 50 includes a lower bit 51, which is set to move in the vertical direction.

[0054] Specifically, after the motor, piston shaft, and lead screw nut assembly are inserted, the lower pressing assembly 10 presses the motor against the support base 90 from above. The rotating mold head 31 of the limiting clamping assembly 30 extends into the motor and engages with the rotor to prevent the rotor and lead screw nut from rotating. Simultaneously, the upper wrench head 21 is inserted into the screwing groove at the upper end of the piston shaft. Then, the upper lifting assembly 40 drives the lower screwing assembly 50 to rise, causing the lower wrench head 51 to press against the locking screw of the lead screw. The lower screwing assembly 50 tightens the locking screw to complete the lower end locking installation of the lead screw nut assembly. Then, the upper screwing assembly 20 drives the piston shaft to rotate so that it is screwed onto the lead screw nut, thereby achieving automatic locking installation of the piston shaft. Furthermore, since the rotating mold head 31 is detachable and the upper wrench head 21 and lower wrench head 51 are respectively arranged to move vertically, the piston shaft locking device can adapt to various models, internal cavity structures, and sizes of linear piston motors by changing the rotating mold head 31 and automatically adjusting the upper and lower pressing positions, thus having stronger adaptability and compatibility.

[0055] For example, such as Figure 1 , Figure 2 and Figure 5 As shown, the base includes a base plate 100, a top plate 200 and a lower mounting plate 400. The top plate 200 is mounted above the base plate 100 via a support column 300, and the lower mounting plate 400 is connected to the base plate 100 and located below the base plate 100.

[0056] For example, such as Figures 1-3 As shown, the pressing assembly 10 includes a pressing drive 11 and a pressing mounting plate 12. The pressing drive 11 is mounted on the top plate 200. The output end of the pressing drive 11 is vertically extended downward and passes through the top plate 200. The pressing mounting plate 12 is connected to the output end of the pressing drive 11. The upper screwing assembly 20 and the limiting clamping assembly 30 are both mounted on the pressing mounting plate 12.

[0057] For example, such as Figure 3 As shown, the pressing mounting plate 12 is connected to four pressing guide rods 17 arranged vertically. All four pressing guide rods 17 pass through the top plate 200. The upper ends of two adjacent pressing guide rods 17 are connected by a guide rod connecting block 18, which is located above the top plate 200. The guide rod connecting block 18 can mechanically limit the pressing amplitude of the pressing mounting plate 12 and enhance the structural stability of the pressing assembly 10.

[0058] For example, the pressing drive 11 is an electric actuator. In other embodiments, the pressing drive 11 may also be a linear drive such as a hydraulic cylinder.

[0059] For example, such as Figure 3As shown, the pressing assembly 10 also includes four pressing guide rods 13, four pressing elastic members 14, and a movable pressure plate 15. The pressing mounting plate 12 is provided with four first linear bearings 16 that are vertically arranged. The four pressing guide rods 13 are slidably inserted through the four first linear bearings 16 in a vertical direction. The movable pressure plate 15 is connected to the lower end of the pressing guide rods 13. The pressing elastic members 14 are sleeved on the pressing guide rods 13, and the two ends of the pressing elastic members 14 are respectively connected to or abut against the pressing mounting plate 12 and the movable pressure plate 15. The pressing elastic members 14 have a tendency to push the movable pressure plate 15 downward so that the movable pressure plate 15 presses against the motor, thereby pressing the motor against the support base 90.

[0060] For example, such as Figure 3 As shown, the movable pressure plate 15 is configured as a ring structure, and the upper screwing assembly 20 and the limiting clamping assembly 30 can pass through the central through hole of the movable pressure plate 15 when they are raised and lowered.

[0061] For example, the pressing elastic element 14 is a compression spring. Of course, in other embodiments, the pressing elastic element 14 may also be other elastic elements such as rubber pillars.

[0062] For example, such as Figure 4 As shown, the limiting clamping assembly 30 also includes a limiting base plate 32, four limiting guide rods 33, four limiting elastic elements 34, and a limiting pressure plate 35. The limiting base plate 32 is mounted on the bottom surface of the lower pressure mounting plate 12. The limiting base plate 32 is provided with four second linear bearings 36 that are vertically arranged through it. The four lower limiting guide rods 33 are correspondingly slidably passed through the four second linear bearings 36 in the vertical direction. The lower pressure mounting plate 12 is provided with clearance holes for each of the four limiting guide rods 33. The limiting guide rod 33 passes through, and the limiting pressure plate 35 is connected to the lower end of the four limiting guide rods 33. The rotating mold head 31 is detachably connected to the limiting pressure plate 35. The limiting elastic member 34 is sleeved on the limiting guide rod 33, and the two ends of the limiting elastic member 34 are respectively connected to or abut against the limiting base plate 32 and the limiting pressure plate 35. The limiting elastic member 34 has the tendency to push the limiting pressure plate 35 downward, so as to drive the rotating mold head 31 to elastically press the rotor, ensuring reliable clamping while avoiding damage to the rotor.

[0063] For example, the limiting elastic element 34 is a compression spring. Of course, in other embodiments, the limiting elastic element 34 may also be other elastic elements such as rubber pillars.

[0064] For example, such as Figure 4 As shown, the rotating mold head 31 is configured as a cylindrical structure, and the upper screwing assembly 20 passes through its central through hole when it is raised and lowered. The lower end of the rotating mold head 31 is provided with multiple downward protruding snap-fit ​​parts 311, which are used to snap-fit ​​the slots in the rotor.

[0065] For example, such as Figure 3 and Figure 4 As shown, the limiting clamping assembly 30 also includes a bottom-probing sensor 37 and a bottom-probing sensor 38. The bottom-probing sensor 37 is installed on the upper end of the limiting guide rod 33, which extends from above into the pressing mounting plate 12. The bottom-probing sensor 38 is installed on the side wall of the pressing mounting plate 12. The bottom-probing sensor 37 extends horizontally and protrudes from the side wall of the pressing mounting plate 12. When the distance that the limiting guide rod 33 slides upward relative to the pressing mounting plate 12 is within a preset range, the bottom-probing sensor 38 detects the bottom-probing sensor 37. Specifically, when the distance that the limiting guide rod 33 slides upward relative to the pressing mounting plate 12 exceeds the preset range, it indicates that the rotating mold head 31 has contacted the bottom of the rotor and the limiting elastic element 34 has been compressed to a certain extent. The locking part 311 is locked with the rotor. At this time, the bottom-probing sensor 37 is out of the detection range of the bottom-probing sensor 38, and the bottom-probing sensor 38 transmits a signal outward to indicate that the rotating mold head 31 has reached the bottom and locked in place.

[0066] For example, the bottom-detection sensor 38 employs a photoelectric proximity switch.

[0067] For example, such as Figure 3 and Figure 4 As shown, the pressing mounting plate 12 is provided with a first vertical clearance hole, the limiting base plate 32 is provided with a second vertical clearance hole 321, and the limiting pressure plate 35 is provided with a third vertical clearance hole 351. The upper screwing assembly 20 also includes an upper screwing drive 22 and an upper screwing sleeve 23. The upper screwing drive 22 is mounted on the lower mounting plate 12, and its output end passes vertically through the first clearance hole and the second clearance hole 321. The upper screwing sleeve 23 is mounted on the output shaft of the upper screwing drive 22, and has an upper movable guide hole 24 extending vertically. An upper guide pin 25 is fixed on the side wall of the upper screw bit 21. The upper screw bit 21 passes vertically inside the upper screwing sleeve 23, and the upper guide pin 25 passes through the upper movable guide hole 24. The upper screwing sleeve 23 and the upper screw bit 21 pass vertically through the third clearance hole 351. Specifically, for piston shafts of different lengths, the height of the upper end of the piston shaft is different, and the axial movement of the upper screw bit 21 can adapt it to piston shafts of various lengths.

[0068] For example, the upper turning drive 22 is a servo rotary motor.

[0069] For example, such as Figure 5 As shown, the upper top assembly 40 includes an upper top drive member 41 and an upper top mounting plate 42. The upper top drive member 41 is mounted on the lower mounting plate 400, and the output end of the upper top drive member 41 is vertically extended and retracted, passing through the lower mounting plate 400. The upper top mounting plate 42 is connected to the output end of the upper top drive member 41, and the lower screwing assembly 50 is mounted on the upper top mounting plate 42. Figure 6As shown, the support base 90 is provided with a clearance through hole 91, and the base plate 100 is provided with a clearance structure corresponding to the clearance through hole 91. The upper drive member 41 drives the lower screwing assembly 50 to pass upward through the clearance structure of the base plate 100 and the clearance through hole 91 of the support base 90, so that the lower bit 51 can reach the locking screw at the bottom of the motor.

[0070] For example, the upper drive member 41 is an electric actuator. In other embodiments, the upper drive member 41 may also be a linear drive member such as a hydraulic cylinder.

[0071] For example, such as Figure 5 As shown, four third linear bearings 44 are fixed on the upper mounting plate 42, and four upper guide rods 43 arranged vertically are correspondingly inserted through the four third linear bearings 44. The lower ends of the four upper guide rods 43 are connected to the lower mounting plate 400. Limiting rings 45 are installed on the upper ends of at least two upper guide rods 43. The limiting rings 45 are located above the upper mounting plate 42 and are used to limit the rising range of the upper mounting plate 42.

[0072] For example, such as Figure 5 As shown, the upper mounting plate 42 is provided with a vertically penetrating fourth clearance hole, and the lower screwing assembly 50 also includes a lower screwing drive 52, a lower screwing sleeve 53, and an upper elastic member 57. The lower screw drive 52 is installed on the bottom surface of the upper mounting plate 42. The output end of the lower screw drive 52 is connected to the lower screw shaft, which passes through the fourth clearance hole in the vertical direction. The lower screw sleeve 53 is movably sleeved on the lower screw shaft. The lower bit 51 is detachably installed on the upper end of the lower screw sleeve 53. The lower screw sleeve 53 is provided with a lower movable guide hole 54 extending in the vertical direction. A lower guide pin 55 is fixed on the lower screw shaft and passes through the lower movable guide hole 54. The two ends of the upper elastic member 57 are respectively connected to or abut against the upper mounting plate 42 and the lower screw sleeve 53. The upper elastic member 57 has a tendency to push the lower screw sleeve 53 upward so that the lower bit 51 elastically presses the locking screw.

[0073] For example, the lower turning drive 52 adopts a servo rotary motor. The output end of the lower turning drive 52 is connected in sequence to the reducer 58, the coupling 59 and the lower turning shaft. The reducer 58 is installed below the upper mounting plate 42 through the reducer mounting plate 581, and the upper elastic member 57 is sleeved on the lower turning shaft.

[0074] For example, the upper elastic element 57 is a compression spring. Of course, in other embodiments, the upper elastic element 57 may also be other elastic elements such as a rubber column.

[0075] For example, such as Figure 5As shown, the lower screwing assembly 50 also includes a first upper top sensor 561 and a second upper top sensor 562. Both the first upper top sensor 561 and the second upper top sensor 562 are mounted on the upper top mounting plate 42 via the mounting bracket 563 and are located beside the lower screwing sleeve 53. The first upper top sensor 561 is located above the second upper top sensor 562. The first upper top sensor 561 and the second upper top sensor 562 are used to detect the vertical position of the lower guide pin 55. Specifically, before the lower bit 51 is fully extended, the first upper sensor 561 detects the lower guide pin 55. After the lower bit 51 contacts the locking screw, as the upper drive member 41 continues to extend, the first upper sensor 561 and the second upper sensor 562 move upward, the upper elastic member 57 is compressed, and the lower guide pin 55 moves downward relative to the lower movable guide hole 54. The lower guide pin 55 is removed from the detection range of the first upper sensor 561 until the lower guide pin 55 is detected by the second upper sensor 562. After the second upper sensor 562 detects the lower guide pin 55, it transmits a signal to indicate that the lower bit 51 is fully extended.

[0076] For example, such as Figure 1 and Figure 2 As shown, the dust removal mechanism 60 is located at the dust removal station and is installed at the output end of the lower pressure assembly 10. It is connected to the side of the lower pressure mounting plate 12 via a dust removal mounting plate. The dust removal mechanism 60 includes an air blowing tank 61, multiple air blowing pipes 62, and a dust suction cylinder 63. The air blowing tank 61 is installed below the dust removal mounting plate. One end of each of the multiple air blowing pipes 62 extends into the air blowing tank 61, and the other end is connected to the air pump. The dust suction cylinder 63 is installed on the dust removal mounting plate, with its lower end connected to the air blowing tank 61 and its upper end connected to a dust collection device via an air pipe. During dust removal operations, the air blowing tank 61 covers the motor. The air pump blows air into the motor cavity through the air blowing pipes 62, causing dust to rise. The dust collection device then sucks away the dust from above through the dust suction cylinder 63, thereby achieving dust removal from the motor cavity.

[0077] For example, such as Figure 6 As shown, the transverse mechanism 70 includes a transverse base 71, a transverse drive 72, a transverse plate 73, a transverse slide rail 74, a transverse slider 75, a buffer seat 76, a hydraulic buffer 77, and a limiting bolt 78. The transverse base 71 and the transverse drive 72 are fixed to the base plate 100. The transverse plate 73 is connected to the transverse drive 72, and the transverse plate 73 is slidably connected to the transverse slide rail 74 through multiple transverse sliders 75. Both ends of the transverse slide rail 74 are provided with buffer seats 76. The buffer seats 76 are equipped with hydraulic buffers 77 and limiting bolts 78 to limit the movement limit position of the transverse plate 73.

[0078] For example, the lateral drive 72 may be a linear cylinder module or a linear motor module.

[0079] For example, such as Figure 6As shown, the support base 90 is provided with a limiting flange 92, two positioning posts 93 and a guard plate 94. The limiting flange 92 is wrapped around the upper edge of the clearance through hole 91. The positioning posts 93 and the guard plate 94 protrude vertically from the upper surface of the support base 90. When the motor is placed on the support base 90, the limiting flange 92 is embedded in the bottom of the motor, and the two positioning posts 93 extend into the positioning holes at the upper edge of the motor to jointly limit the motor. The guard plate 94 is located on the side of the motor, and the height of the guard plate 94 does not exceed the motor body. The guard plate 94 is used to protect the motor from the side.

[0080] For example, such as Figure 1 and Figure 2 As shown, the locking piston shaft device also includes a barcode scanning component 80, which is installed at the locking piston shaft station. The barcode scanning component 80 is used to scan the barcode on the motor in front of the locking piston to identify the motor model and prevent operators from putting in the wrong model of motor, which could cause production accidents.
