Description

Technical Field

[0001] The present invention relates to the technical field of mechanical assembly, and particularly to an electric keyed stud installation tool, which is mainly used for the assembly of keyed double-headed studs. Background Art

[0002] Aviation transmission equipment usually uses a casing to achieve closed transmission, and multiple casing bodies are usually connected by studs. A keyed stud consists of a stud and a locking key. The stud refers to a double-headed stud with two notches at the large end. During installation, the large end of the double-headed stud is first inserted into the body, and then the locking key is pressed into the threaded hole of the body, and the other end is connected to other casing bodies. After the locking key is pressed into the body, it is embedded in the thread of the body to achieve the anti-rotation purpose. The installation of the keyed stud has relatively high requirements for the relative position accuracy between the stud end face and the casing installation surface. This accuracy is difficult to guarantee during manual installation, and the manual installation efficiency is low. In addition, the thickness of the locking key is generally thin, and it is extremely easy to break due to the skew of the pressing force direction during the process of pressing it into the threaded hole of the casing. The existing installation technology has problems of low efficiency and poor installation quality, seriously affecting the connection effect of the keyed stud in the casing assembly.

[0003] The "a keyed stud installation tool" disclosed in Chinese Patent CN215509878U has the advantage of axially positioning the end face of the keyed stud. A high-precision shoulder is set in the installation tool to ensure the relative position accuracy requirement between the stud end face and the casing installation surface. The tool provides guidance for the process of pressing the locking key, effectively preventing the deformation of the locking key under the impact force, and improving the installation quality of the keyed stud. However, it is a manual assembly, with complex operation, poor installation efficiency, and poor interchangeability for the installation of keyed studs of different models. Summary of the Invention

[0004] In view of the above problems, the purpose of the present invention is to provide an electric keyed stud installation tool that is convenient to operate, has good consistency in installation quality, adjustable screwing and pushing speeds, can real-time feedback the installation state, and improves the installation quality and speed of the keyed stud.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] An electric keyed stud installation tool includes a housing that is hollow inside and serves as an installation base, and a stud installation assembly, a locking key installation assembly, and a power module that are respectively installed inside the housing.

[0007] The screw installation assembly is used to screw the keyed screw (stud) into the machine body, and includes a rotating motor, a rotating rod, and a stud connection seat; the two ends of the rotating rod are respectively connected to the rotating shaft of the rotating motor and one end of the stud connection seat, and the rotating rod and the stud connection seat can rotate in the housing under the drive of the rotating motor; the other end of the stud connection seat extends out of the housing and is detachably connected to one end of the keyed screw. The rotating motor drives the rotating rod to rotate, and the rotating rod drives the replaceable stud connection seat connected to the other end to rotate, and at the same time, the stud connection seat drives the keyed screw (stud) connected to the other end to rotate, and screws the keyed screw into the specified position of the machine body.

[0008] The lock key installation assembly is used to push the lock key on the screw into the machine body, which includes a push-in screw, a sleeve connection seat, a lock key sleeve, a rotating nut, and a push-in motor; the push-in screw is a cylinder that is slidably sleeved outside the rotating rod; the sleeve connection seat is a cylinder that is slidably sleeved outside the rotating rod and the stud connection seat, one end of which is connected to the push-in screw and the other end extends out of the shell; the lock key sleeve is a cylinder that is detachably connected to the other end of the sleeve connection seat; the rotating nut is threadedly connected to the outside of the push-in screw, and its outer side is connected to the rotating shaft of the push-in motor and can drive the push-in screw to move linearly under the drive of the push-in motor. The rotation of the push-in motor drives the rotating nut to rotate, and the rotation of the rotating nut causes the push-in screw to move axially, thereby driving the sleeve connection seat to move, so that the lock key sleeve pushes the lock key into the machine body. After that, the push-in screw automatically retreats, and the rotating rod automatically reverses at the same time, separating the tool from the stud, and completing the installation of the stud.

[0009] The power supply module is electrically connected to the rotating motor and the pushing motor respectively, and is mainly used to supply power for the operation of the rotating motor and the pushing motor.

[0010] Furthermore, in order to provide guidance for the push-in screw rod and the pressing sleeve connecting seat, the electric keyed screw pile installation tool also includes a guide mounting seat, a guide mounting sleeve, and a guide sleeve which are connected together in sequence and located outside the shell; wherein the guide mounting seat is connected to the shell; the guide mounting seat, the guide mounting sleeve, and the guide sleeve are connected as a whole and then sleeved outside the pressing sleeve connecting seat.

[0011] Furthermore, the two ends of the stud connection seat are respectively threadedly connected with one end of the rotating rod and one end of the keyed screw. The key-locking sleeve is threadedly connected to the other end of the sleeve connection seat. This arrangement can connect the stud connection seat and the key-locking sleeve of corresponding specifications as needed according to the different models of the keyed screw and the key-locking sleeve.

[0012] Further, in order to achieve the transmission connection between the pushing motor and the rotating nut and realize speed reduction and distance increase, the pushing motor and the rotating nut are transmission-connected through a gear transmission system arranged in the housing; the gear transmission system includes a pushing motor gear, a rotating transmission rod, a first-stage rotating gear, a second-stage rotating gear, and a third-stage rotating gear; the pushing motor gear is installed on the rotating shaft of the pushing motor; the rotating transmission rod is rotatably installed in the housing and is parallel to the rotating rod; the first-stage rotating gear and the second-stage rotating gear are respectively fixed at both ends of the rotating transmission rod, and the first-stage rotating gear meshes with the pushing motor gear; the third-stage rotating gear is fixed on the rotating nut and meshes with the second-stage rotating gear.

[0013] Further, for the convenience of operating the installation tool, a handle is integrally provided at the lower part of the housing, and a control button for controlling the start or stop of the rotating motor and the pushing motor is provided on the handle. The control button adopts a two-stage button. After the first-stage button rotates the keyed stud into place, the second-stage button is pressed to perform the key locking installation.

[0014] Further, the electric keyed stud installation tool further includes a control module, and the control module includes a single-chip microcomputer, a Hall sensor, and a positioning magnet; the single-chip microcomputer is installed in the housing and is electrically connected to the Hall sensor, the power module, the pushing motor, the control button, and the rotating motor respectively; the positioning magnet is installed on the pushing screw rod and can move linearly with the pushing screw rod; the Hall sensor is installed in the housing and corresponds to the positioning magnet; when the pushing screw rod is in the initial position, the positioning magnet is directly opposite to the Hall sensor; when the pushing screw rod moves towards the inside of the housing, the positioning magnet approaches the Hall sensor; when the pushing screw rod moves towards the outside of the housing, the positioning magnet moves away from the Hall sensor; before the single-chip microcomputer and the power module are powered on and the control button is not pressed, when the single-chip microcomputer detects through the Hall sensor that the pushing screw rod is not in the initial position, the single-chip microcomputer controls the pushing motor to drive the pushing screw rod to move to the initial position.

[0015] Further, the control module further includes a pressure sensor arranged in the housing. One end of the pressure sensor is in direct or indirect contact with the rotating nut, and the other end is in direct or indirect contact with a preset limiting plate inside the housing; the pressure sensor is electrically connected to the single-chip microcomputer and is used for measuring the reaction force received by the rotating nut and transmitting it to the single-chip microcomputer for comprehensive processing. After the key is pressed into the body by the key pressing sleeve under the push of the pushing screw rod, a reaction force will be applied to the pushing screw rod. This reaction force is transmitted by the pushing screw rod to the rotating nut and then to the pressure sensor. When the pressure sensor detects that the reaction force reaches the set value, the single-chip microcomputer controls the pushing motor to reverse and drive the pushing screw rod to automatically retract, and at the same time, the single-chip microcomputer controls the rotating motor to reverse and drive the rotating rod to automatically reverse and separate from the double-headed stud.

[0016] Further, the control module further includes a pressure setting button and a display, both of which are electrically connected to the single-chip microcomputer. The pressure setting button is used to set different key-pushing forces, and the display is used to display different pressure values.

[0017] Further, a fixed front cover and a fixed rear cover sleeving the pushing screw rod are respectively arranged on both sides of the rotating nut. The fixed front cover and the fixed rear cover are used to limit the lateral displacement of the rotating nut. One side of the fixed front cover is fixed inside the housing near the bushing connecting seat, and the other side rotatably connects one end of the rotating nut therein. The fixed rear cover is slidably arranged inside the housing away from the bushing connecting seat. One side of it is connected to the pressure sensor, and the other side rotatably connects one end of the rotating nut therein.

[0018] Further, the electric keyed stud installation tool further includes a rotating rod mounting sleeve, a disc spring retainer, and a disc spring. The rotating rod mounting sleeve is sleeved outside the rotating rod and located between the limit plate and the pressure sensor. One end of it is connected to the pressure sensor, and the other end does not contact the limit plate. The disc spring retainer is sleeved outside the rotating rod and located inside the pressure sensor. Its outer side contacts the pressure sensor and can move towards the limit plate under the push of the pressure sensor. The disc spring is sleeved outside the rotating rod and located inside the disc spring retainer. Both ends of it contact the disc spring retainer and the rotating rod respectively. The reaction force generated during the key-pushing process is transmitted to the pressure sensor and then absorbed by the disc spring. The corresponding force value is collected by the pressure sensor and displayed by the display.

[0019] Further, the power supply module includes a storage battery. The storage battery is installed at the lower part of the handle and is electrically connected to the Hall sensor, the pushing motor, the single-chip microcomputer, the rotating motor, the pressure sensor, and the display respectively to supply power to the Hall sensor, the pushing motor, the single-chip microcomputer, the rotating motor, the pressure sensor, and the display.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The stud screwing and key pressing are driven by motors and controlled by a single-chip microcomputer program, so the operation is simple and convenient, and the installation efficiency is higher and the quality is better.

[0022] (2) The replaceable double-headed stud connecting seat is adopted, which can install different models of keyed studs and provides the possibility for the installation of similar products of keyed studs.

[0023] (3) The reaction force generated during the key-pushing process is absorbed by the disc spring. The corresponding force value is collected by the pressure sensor and displayed by the display. Description of the Drawings

[0033] Embodiment 1:

[0034] As Figures 1 - 3 shown, an electric keyed stud installation tool of the present invention includes:

[0035] A housing 1, the interior of the housing 1 is hollow and serves as an installation base. A handle for easy hand grasping is integrally connected to the lower part of the housing 1. At the same time, a guiding mechanism communicating with the interior of the housing 1 is horizontally provided on the right side of the housing 1 externally. The guiding mechanism is in a cylindrical shape and includes a guiding mounting seat 4, a guiding mounting sleeve 5, and a guiding sleeve 6 that are sequentially threadedly connected together. Among them, the guiding mounting seat 4 is connected to and communicates with the housing 1, and the guiding mounting seat 4, the guiding mounting sleeve 5, and the guiding sleeve 6 are all in a cylindrical shape.

[0036] A stud installation assembly, the stud installation assembly is installed in the housing 1 and is used to screw a keyed stud (double-headed stud) into the machine body, such as Figure 2 and Figure 3As shown, the stud installation assembly includes a rotary motor 28, a rotary rod 10, and a double-headed stud connecting seat 8. The rotary motor 28 is horizontally installed on the left side inside the housing, and its rotating shaft faces right; the left part of the rotary rod 10 is horizontally arranged inside the housing 1, and the right part extends out of the housing 1 and is sleeved in the guiding mechanism. One end (left end) of the rotary rod 10 is coaxially connected to the rotating shaft of the rotary motor 28 (through a pin shaft). The other end (right end) of the rotary rod 10 is threadedly connected to one end (left end) of the double-headed stud connecting seat 8 (coaxially connected. By using this detachable double-headed stud connecting seat 8, corresponding specifications of double-headed stud connecting seats can be connected as required according to different types of keyed studs). The rotary rod 10 and the double-headed stud connecting seat 8 can rotate inside the housing 1 under the drive of the rotary motor 28. The double-headed stud connecting seat 8 is sleeved in the guiding mechanism, and its right end extends out of the guiding mechanism and is threadedly connected to one end of the keyed stud (a threaded hole is provided at the right end of the double-headed stud connecting seat 8, and the double-headed stud connecting seat 8 is threadedly connected to one end of the keyed stud through this threaded hole); in addition, a locking head 9 (using a conventional locking device, such as a locking nut) that cooperates with the double-headed stud connecting seat 8 is provided at the right end of the rotary rod 10 to prevent the rotary rod 10 and the double-headed stud connecting seat 8 from loosening when the rotary rod 10 rotates in the reverse direction. When installing the keyed stud, the rotary motor 28 drives the rotary rod 10 to rotate, the rotary rod 10 drives the replaceable double-headed stud connecting seat 8 connected to its other end to rotate, and at the same time, the double-headed stud connecting seat 8 drives the keyed stud (double-headed stud) connected to its other end to rotate and screws the keyed stud into the specified position of the machine body.

[0037] A key locking installation assembly, which is installed inside the housing 1 and is used to push the key on the keyed stud into the machine body, such as Figure 2 and Figure 3As shown, the lock key installation assembly includes a push-in screw rod 13, a pressing sleeve connection seat 11, a lock key pressing sleeve 7, a rotating nut 35, a push-in motor 20, a fixed front cover 15, and a fixed rear cover 33. The push-in screw rod 13 is a cylinder (open at both ends) that is slidably sleeved outside the rotating rod 10, and a thread is provided on the outside (in order to keep it moving in a straight line, a slide bar can be provided on both sides of its left end, and correspondingly, a slide groove that slides with the slide bar is provided inside the housing 1, and the slide bar extends into the slide groove and moves back and forth along the slide groove. When the push-in screw rod 13 moves horizontally to the left and right, it is restricted by the slide groove and can only move in a straight line. The pressing sleeve connection seat 11 is also a cylinder (open at both ends) that is slidably sleeved outside the rotating rod 10 and the stud connection seat 8, and one end (left end) is threadedly connected (coaxially connected) with the push-in screw rod 13, and the right side of the pressing sleeve connection seat 11 is sleeved in the guide structure and its right end extends out of the guide structure. The lock key pressing sleeve 7 is a cylinder (open at both ends) threadedly connected to the other end (right end) of the pressing sleeve connecting seat 11, and adopts a detachable connection. According to the different lock key models of the key screw pile, the lock key pressing sleeve 7 of the corresponding specifications can be connected as needed. The rotating nut 35 is threadedly connected to the outside of the push-in screw 13 (the structure of the rotating nut 35 is similar to the screw nut of the ball screw pair, and the rotating nut 35 cooperates with the push-in screw 13 to form a structure similar to the ball screw pair), and the outer side of the rotating nut 35 is connected to the rotating shaft of the push-in motor 20 through a gear transmission system (and the gear transmission system is used to achieve speed reduction and distance increase). The rotating nut 35 can drive the push-in screw 13 to move linearly under the drive of the push-in motor 20. The fixed front cover 15 and the fixed rear cover 33 are respectively arranged on the left and right sides of the rotating nut 35 and are sleeved on the outside of the push-in screw rod 13. The fixed front cover 15 and the fixed rear cover 33 are used to limit the lateral displacement of the rotating nut 35; one side (right side) of the fixed front cover 15 is fixed to a position inside the outer shell 1 close to the pressing sleeve connecting seat 11, and the other side (left side) rotates one end (right end) of the rotating nut 35 therein through the rotating nut front bearing 14; the fixed rear cover 33 is slidably arranged at a position inside the outer shell 1 away from the pressing sleeve connecting seat 11, one side (left side) of the fixed rear cover 33 is connected to the pressure sensor 32, and the other side (right side) of the fixed rear cover 33 rotates one end (right end) of the rotating nut 35 therein through the rotating nut rear bearing 34. When the lock key is pressed in, the push-in motor 20 rotates to drive the rotating nut 35 to rotate. During the rotation of the rotating nut 35, due to the restrictions of the fixed front cover 14 and the fixed rear cover 33, the push-in screw rod 13 will undergo axial movement (linear movement), thereby driving the pressing sleeve connecting seat 11 to move linearly and push the lock key pressing sleeve 7 forward to push the lock key into the body. After that, the push-in screw rod 13 automatically retreats, and the rotating rod 10 automatically reverses to separate the installation tool from the stud, completing the installation of the stud.

[0038] A control module, which is installed inside the housing and is used to control the operation of the screw pile installation components, thereby completing various functions, such as Figure 4 As shown, the control module includes a single-chip microcomputer 24, a Hall sensor 2, a positioning magnet 3, a control button 21, a pressure sensor 32, a pressure setting button 37, and a display 38; As Figure 3As shown, the single-chip microcomputer 24 is installed in the housing 1 and is electrically connected to the Hall sensor 2, the power supply module, the pushing motor 20, the control button 21, the rotating motor 28, the pressure sensor 32, the pressure setting button 37, and the display 38 respectively, and is used to execute the corresponding programs written therein to complete various functions; the positioning magnet 3 is installed on the pushing screw rod 13 through the positioning magnet mounting seat 12 and can move linearly with the pushing screw rod 13 (the positioning magnet mounting seat 12 is fixed on the pushing screw rod 13, and the positioning magnet 3 is installed on the positioning magnet mounting seat 12); the Hall sensor 2 is installed in the housing 1 and corresponds to the position of the positioning magnet 3. When the pushing screw rod 13 is at the initial position, the positioning magnet 3 faces the Hall sensor 2; when the pushing screw rod 13 moves towards the inside of the housing 1, the positioning magnet 3 approaches the Hall sensor 2; when the pushing screw rod 13 moves towards the outside of the housing 1, the positioning magnet 3 moves away from the Hall sensor 2; before the single-chip microcomputer 24 and the power supply module are powered on and the control button 21 is not pressed, when the single-chip microcomputer 24 detects through the Hall sensor 2 that the pushing screw rod 13 is not at the initial position, the single-chip microcomputer 24 controls the pushing motor 20 to drive the pushing screw rod 13 to move to the initial position. The control button 21 adopts a two-stage button. After the first-stage button rotates the keyed stud into place, the second-stage button is pressed for key locking installation. The first-stage button is used to control the start or stop of the rotating motor 28, and the second-stage button is used to control the start or stop of the pushing motor 20. The pressure sensor 32 is sleeved outside the rotating rod 10 and the pushing screw rod 13, and is used to measure the reaction force received by the rotating nut 35 and transmit it to the single-chip microcomputer 24 for comprehensive processing. One end (right end) of the pressure sensor 32 is connected to the fixed rear cover 33 (i.e., indirectly contacts the rotating nut 35), and the other end (left end) directly or indirectly contacts the limit plate 36 preset inside the housing 1. When the lock key is pressed into the body by the lock key pressing sleeve 7 under the push of the pushing screw rod 13, a reaction force will be applied to the pushing screw rod 13. This reaction force is transmitted by the pushing screw rod 13 to the rotating nut 35, and the rotating nut 35 then transmits it to the pressure sensor 32. When the pressure sensor 32 detects that the reaction force reaches the set value (a thrust value is preset in advance through the pressure setting button 37), the single-chip microcomputer 24 controls the pushing motor 20 to reverse and drive the pushing screw rod 13 to automatically retract, and at the same time, the single-chip microcomputer 24 controls the rotating motor 28 to reverse and drive the rotating rod 10 to automatically reverse and separate from the double-headed stud. The pressure setting button 37 and the display 38 are both installed on the outer side wall of the housing 1; the pressure setting button 37 is used to set different lock key pushing forces; the display 38 selects an OLED screen and is used to display different pressure values.

[0039] The power supply module, such as Figure 4As shown in the figure, the power supply module includes a storage battery 22 and a battery interface 23; the storage battery 22 is installed at the lower part of the handle and is electrically connected to the Hall sensor 2, the pushing motor 20, the single-chip microcomputer 24, the rotating motor 28, the pressure sensor 32, and the display 38 through the battery interface 23 (the storage battery 22 and the battery interface 23 are electrically connected), so as to supply power to the Hall sensor 2, the pushing motor 20, the single-chip microcomputer 24, the rotating motor 28, the pressure sensor 32, and the display 32.

[0040] The operation steps of the installation tool are as follows:

[0041] (1) Reset the pushing screw rod 13: After the storage battery 22 is installed in the housing 1 and the battery interface 23 is powered on, the program written into the single-chip microcomputer 24 runs, and the installed Hall sensor 2 automatically detects whether the pushing screw rod 13 reaches the initial position. If it does not reach the initial position, the pushing motor 20 is controlled to rotate, and the pushing motor 20 drives the rotating nut 35 to rotate and makes the pushing screw rod 13 move linearly to reach the set initial position.

[0042] (2) Screw the stud into the body: After pressing the first section of the control button 21, the single-chip microcomputer 24 controls the rotating motor 28 to rotate. The rotating motor 28 drives the rotating rod 10 to rotate through the connecting pin, and the rotating rod 10 drives the replaceable double-headed stud connecting seat 8 to rotate, so that the stud to be connected threaded on the other end of the double-headed stud connecting seat 8 rotates and is screwed into the specified position of the body. The locking head 9 cooperates with the double-headed stud connecting seat 8 to prevent the rotating rod 10 and the double-headed stud connecting seat 8 from loosening during reverse rotation.

[0043] (3) Push the locking key into the body: After the stud is screwed into the body, press the second section of the control button 21. The single-chip microcomputer 24 controls the locking key pushing motor 20 to rotate. After the pushing motor 20 rotates, it drives the rotating nut 35 to rotate through the gear transmission system. Due to the limitation of the fixed front cover 15 and the fixed rear cover 33, the pushing screw rod 13 will move axially, thereby driving the pressure sleeve connecting seat 11 to move, so that the locking key pressure sleeve 7 pushes the locking key into the body. When the built-in pressure sensor 32 detects that the thrust reaches the set value, the single-chip microcomputer 24 controls the pushing motor 20 to rotate and drives the pushing screw rod 13 to automatically retract. At the same time, the single-chip microcomputer 24 controls the rotating motor 28 and drives the rotating rod 10 to automatically reverse, separating the installation tool from the double-headed stud to complete the installation of the double-headed stud.

[0044] Embodiment 2:

[0045] The difference between this embodiment and Embodiment 1 is:

[0046] Such as Figure 2 And Figure 3As shown in the figure, the gear transmission system includes a push-in motor gear 25, a rotating transmission rod 19, a rotating first-stage gear 26, a rotating second-stage gear 18, and a rotating third-stage gear 16; the push-in motor gear 25 is installed on the rotating shaft of the push-in motor 20; the rotating transmission rod 19 is rotatably installed in the housing 1 and is parallel to the rotating rod 10; the rotating first-stage gear 26 and the rotating second-stage gear 18 are respectively fixed at both ends of the rotating transmission rod 19, wherein the rotating first-stage gear 26 meshes with the push-in motor gear 25; the rotating third-stage gear 16 is fixed on the rotating nut 35 and meshes with the rotating second-stage gear 18. The push-in motor 20 rotates and drives the push-in motor gear 25 on it to rotate, and then drives the rotating transmission rod 19 to rotate through the rotating first-stage gear 26. While the rotating transmission rod 19 rotates, it drives the rotating second-stage gear 18 to rotate. The rotation of the rotating second-stage gear 18 then drives the rotating third-stage gear 16 to rotate, and the rotation of the rotating third-stage gear 16 finally causes the rotating nut 35 to rotate. The diameters of the push-in motor gear 25 and the rotating second-stage gear 18 are both smaller than the diameters of the rotating first-stage gear 26 and the rotating third-stage gear 16. Both ends of the rotating transmission rod 19 are rotatably installed in the housing 1 through a front bearing 17 of the rotating transmission rod and a rear bearing 27 of the rotating transmission rod.

[0047] Embodiment 3:

[0048] The difference between this embodiment and Embodiment 1 is that:
