Description

Technical Field

[0001] This invention relates to an automatic grinding machine for multi-station toothed meshing moving components, belonging to the field of mechanical manufacturing automotive welding fixture parts production technology. Background Technology

[0002] In the field of automotive welding fixtures, centering and clamping mechanisms are frequently used as auxiliary tooling to position and clamp automotive body parts to meet the precision requirements of final welding. Therefore, centering and clamping mechanisms are widely used in the fixture industry, resulting in various sizes and specifications. However, in the machining and assembly of centering and clamping mechanisms, after high-frequency quenching treatment of the toothed meshing motion components via wire cutting, the relatively moving tooth surfaces need to be ground to ensure smooth centering and clamping movements without jamming during subsequent assembly and use, guaranteeing high reliability and high precision operation. Currently, grinding the tooth surfaces of the toothed meshing motion components is typically done manually. The operator clamps the inner toothed groove fixing seat onto a grinding platform, applies grinding paste, and manually pushes the outer toothed groove moving seat back and forth on the inner toothed groove fixing seat to grind the contact tooth surfaces, reducing their roughness and meeting the usage requirements. In manual operation, grinding a set of toothed meshing motion components takes a lot of time, resulting in low production efficiency. It is a high-load, low-productivity job. At the same time, due to the difference in skills among operators, the consistency of the ground toothed meshing motion components is poor, and there is a need for repeated grinding. Summary of the Invention

[0003] The purpose of this application is to provide an automatic grinding machine for multi-station tooth groove meshing moving components, in order to solve the technical problem that the existing tooth groove surface grinding technology mainly relies on manual grinding, which has low grinding production efficiency and poor consistency of grinding products, thus making it impossible to achieve automatic grinding of multi-station tooth groove meshing moving components.

[0004] To address the aforementioned problems, this invention provides an automatic grinding machine for a multi-station toothed meshing moving component, comprising: a support frame assembly, a workpiece placement assembly, a grinding motion assembly, a grinding drive assembly, and a toothed meshing motion assembly; the support frame assembly is a square frame structure with its bottom in contact with the ground for support; the grinding drive assembly is located above the support frame assembly, serving as the power source for the entire device; inside the support frame assembly, from bottom to top, are the workpiece placement assembly and the grinding motion assembly; the toothed meshing motion assembly is located at the junction of the workpiece placement assembly and the grinding motion assembly, forming the main working area of ​​the device.

[0005] The support frame assembly includes a lower support base and an upper support base. The lower support base is in contact with the ground and has a stepped shape; the bottom of the upper support base is fixed to the top of the lower support base with screws.

[0006] The workpiece placement assembly for grinding includes a workpiece base, a workpiece fixing seat, a locking screw, a T-shaped clamping block, a locking nut, an adjusting bracket, an adjusting handwheel, a slide rail, a slider, a lower bearing mounting seat, a trapezoidal screw, a trapezoidal nut, a trapezoidal nut connector, an upper bearing mounting seat, a lower support bearing, and an upper support bearing. The adjusting bracket is fixed to the back of the upper support seat on the support frame assembly by screws. There is a shaft hole at the center of both the top and bottom of the adjusting bracket. The top shaft hole houses the upper bearing mounting seat, which contains the upper support bearing; the bottom shaft hole houses the lower bearing mounting seat, which also contains the lower support bearing. A trapezoidal screw is installed between the upper and lower support bearings. One end of the long shaft of the trapezoidal screw is installed in the upper support bearing and positioned by a shoulder, with an adjusting handwheel installed at the shaft end; the other end is installed in the lower support bearing. A trapezoidal nut is installed on the threaded portion of the trapezoidal screw, and the two are connected by threads to achieve helical transmission. Two symmetrical grooves are radially formed in the middle of the trapezoidal nut. One end of the trapezoidal nut connector is embedded in the groove of the trapezoidal nut, and the other end is installed on the side of the workpiece base, fixing the lead screw to the workpiece base. The slider is vertically fixed to the back of the workpiece base with screws. The slide rail is vertically fixed to the other side of the adjusting bracket with screws. The movement of the slide rail and the slider together will realize the vertical movement of the workpiece base. The workpiece base has an L-shaped structure, and eight workpiece fixing seats are installed on its upper surface. Two workpiece fixing seats form a group, with a total of four groups, which are used to fix the internal tooth groove fixing seat to be ground. Locking screws are also distributed at intervals on the upper surface of the workpiece base. The upper end of the locking screw is equipped with a T-shaped clamping block that can move along the axial direction of the locking screw. After the workpiece is loaded into the workpiece fixing seat, the T-shaped clamping block is placed on the locking screw, and the locking nut is tightened to fix the internal tooth groove fixing seat of the tooth groove meshing motion component, ensuring that the internal tooth groove fixing seat remains stationary during the grinding process. Thus, when the handwheel is manually rotated, it drives the trapezoidal lead screw to rotate. This rotation causes the trapezoidal nut to move up and down along its axis. The nut, through a connecting component, drives the workpiece base to move up and down along a linear guide. The vertical installation position of the tooth groove fixing seat within the tooth groove meshing motion assembly is adjusted according to the different specifications and dimensions being ground, accommodating the installation and fixing of different grinding products. This invention features four fixed installation positions, thus allowing for simultaneous grinding of four sets of tooth groove meshing motion assemblies.

[0007] The grinding motion assembly includes a lower straight connecting rod, an external toothed groove moving seat connecting rod, an open retaining ring, a cross-shaped connecting seat, an upper straight connecting rod, a connecting rod bracket, a locking nut, a groove connector, a connecting pin, a linear guide shaft, and linear bearings. Two linear bearings are symmetrically installed in the upper surface holes of the upper support seat. The upper end of the linear guide shaft is fixed by the linear bearings, and the lower end of the linear guide shaft is fixed to the upper surface of the connecting rod bracket via a threaded connection, with the upper end passing through the linear bearings. Four upper straight connecting rods are distributed on the connecting rod bracket and fixed to it by connecting rod locking nuts. The upper and lower straight connecting rods are fixed together by the cross-shaped connecting seat, and the open retaining rings confine the upper and lower straight connecting rods within the cross grooves of the cross-shaped connecting seat. The connecting rod of the external gear groove moving seat is threaded at both ends. The upper end connects to the internal thread of the next slotted connecting rod, and the lower end connects to the internal threaded hole of the external gear groove moving seat, guiding the external gear groove moving seat into the two internal gear groove fixed seats of the gear groove meshing motion assembly. A rectangular slot is provided at the center of the connecting rod bracket for connecting the drive connecting rod of the grinding drive assembly, facilitating the mating movement of the slot connector and the drive connecting rod. The lower end of the slot connector is fixed to the middle of the connecting rod bracket by a lock nut, and a connecting pin is installed in the circular hole at the upper end for connecting the drive connecting rod (grinding drive assembly). Through the connecting pin, the movement of the drive connecting rod is transmitted to the connecting rod bracket. Simultaneously, due to the linear guide shaft, the oscillating motion of the drive connecting rod is converted into the up-and-down reciprocating motion of the connecting rod bracket. When the connecting rod bracket moves up and down along the linear guide shaft, the cross-shaped connecting seat eliminates the coaxiality deviation between the upper slotted connecting rod, the lower slotted connecting rod, and the connecting rod of the external gear groove moving seat, preventing jamming or binding during movement.

[0008] The grinding drive assembly is mounted above the support frame assembly and includes a drive linkage, an adjustable output shaft, adjusting shims, an adjusting connecting plate, a disc-shaped output shaft, a reducer, and a motor. The motor is connected to one side of the reducer via a flange, and the reducer is fixed to the upper support mounting surface with screws. One end of the disc-shaped output shaft is connected to the reducer output shaft via a keyway, while the other end has a groove containing the adjustable output shaft. The adjustable output shaft has a grooved circular hole, allowing for radial displacement adjustment within the groove on its end face. This adjustment is then secured by the adjusting shims and the adjusting connecting plate. The drive linkage has spherical bearings at both ends. One bearing is connected to the adjustable output shaft and is locked in place by a lock nut. The other bearing is connected to the groove connector of the grinding motion assembly via a pin. This connection between the grinding drive assembly and the grinding motion assembly allows for adjustment of the grinding stroke range by changing the initial angle of the drive linkage and adjusting the mounting position of the adjustable output shaft on the disc-shaped output shaft, thus meeting the machining requirements of different tooth groove specifications.

[0009] The toothed groove meshing motion assembly comprises an inner toothed groove fixed seat and an outer toothed groove moving seat. The left and right halves of the inner toothed groove fixed seat are combined to form an inner toothed groove fixed seat, whose installation position on the workpiece base is determined by the workpiece fixed seat and secured by a T-shaped clamping block and a locking nut. The outer toothed groove moving seat is nested inside the inner toothed groove fixed seat, and the two achieve meshing and sliding through a toothed structure. Driven by the vertical reciprocating motion of the connecting rod of the outer toothed groove moving seat, the rotational motion of the grinding drive assembly is converted into the linear reciprocating motion of the outer toothed groove moving seat, thereby achieving precise grinding of the inner toothed groove fixed seat and the outer toothed groove moving seat.

[0010] This invention provides a method for using the above-mentioned automatic grinding machine for multi-station toothed meshing moving components, comprising the following steps: (1) Before automatic grinding begins, connect the outer tooth groove moving seat of each set of tooth groove meshing motion components to the outer tooth groove moving seat connecting rod, and then place the two inner tooth groove fixing seats on the workpiece fixing seat respectively, and fix them by T-shaped clamping blocks and locking nuts; (2) Manually rotate the adjustment handwheel to adjust the height of the workpiece base so that the two inner tooth groove fixed seats of each group mesh with the outer tooth groove moving seat; add grinding paste to the tooth groove meshing part and adjust the position of the adjustable output shaft so that the distance range of the adjustable output shaft rotating one revolution to drive the outer tooth groove moving seat to move up and down covers the tooth groove length of the inner tooth groove fixed seat. (3) Then start the motor. The motor rotates and drives the reducer, disc output shaft, adjustable output shaft and drive linkage to convert the rotational motion into the linear motion of grinding between the inner tooth groove fixed seat and the outer tooth groove moving seat in the vertical direction. Automatic grinding is carried out. After the grinding reaches the time requirement, the motor is turned off and the four sets of tooth groove meshing motion components complete the grinding.

[0011] The beneficial effects of this invention are: (1) Improve workpiece grinding efficiency and accelerate order delivery cycle; (2) Ensure the consistency of the grinding process and guarantee the pass rate of the ground products; (3) Optimize staffing and significantly reduce long-term human resource operating costs.

Detailed Implementation

[0022] The present invention will be further illustrated by the following embodiments, but is not limited to the following embodiments. Example 1

[0023] The present invention provides an automatic grinding machine for a multi-station tooth groove meshing moving component, comprising a support frame component 1, a grinding workpiece placement component 2, a tooth groove meshing motion component 3, a grinding motion component 4, and a grinding drive component 5.

[0024] The support frame assembly 1 has a square frame structure in the vertical direction, with its bottom in contact with the ground for support. The grinding drive assembly 5 is located on top of it, serving as the power source for the entire device. Inside, from bottom to top in the vertical direction, are the grinding workpiece placement assembly 2 and the grinding motion assembly 4. The toothed meshing motion assembly 3 is located at the junction of the grinding workpiece placement assembly 2 and the grinding motion assembly 4, forming the main working area of ​​the device.

[0025] The support frame assembly 1 includes a lower support base 6 and an upper support base 7. The lower support base 6 is in contact with the ground and has a stepped shape; the bottom of the upper support base 7 is fixed to the top of the lower support base 6 by screws.

[0026] The workpiece placement assembly 2 includes a workpiece base 8, a workpiece fixing seat 9, a locking screw 10, a T-shaped clamping block 11, a locking nut 12, an adjusting bracket 13, an adjusting handwheel 14, a slide rail 15, a slider 16, a lower bearing mounting seat 17, a trapezoidal lead screw 18, a trapezoidal nut 19, a trapezoidal nut connector 20, an upper bearing mounting seat 21, a lower support bearing 22, and an upper support bearing 23. The adjusting bracket 13 is fixed to the back of the upper support seat 7 of the support frame assembly by screws. There is a shaft hole at the center of both the top and bottom of the adjusting bracket 13. The upper bearing mounting seat 21 is installed in the top shaft hole, and the upper support bearing 23 is installed inside; the lower bearing mounting seat 17 is installed in the bottom shaft hole, and the lower support bearing 22 is installed inside. A trapezoidal lead screw 18 is installed between the upper support bearing 23 and the lower support bearing 22. One end of the long shaft of the trapezoidal lead screw 18 is installed in the upper support bearing 23 and positioned by the shaft shoulder, with an adjusting handwheel 14 installed at the shaft end; the other end is installed in the lower support bearing 22. A trapezoidal nut 19 is installed on the threaded part of the trapezoidal lead screw, and the two are connected by threads to achieve helical transmission. Two symmetrical grooves are radially opened in the middle of the trapezoidal nut 19. One end of the trapezoidal nut connector is embedded in the groove of the trapezoidal nut, and the other end is installed on the side of the workpiece base, fixing the trapezoidal lead screw 18 to the workpiece base. The slider 16 is vertically fixed to the back of the workpiece base by screws. The slide rail 15 is vertically fixed to the other side of the adjusting bracket 13 by screws. The movement of the slide rail and the slider will realize the vertical movement of the workpiece base. The workpiece base 8 has an L-shaped structure, and eight workpiece fixing seats 9 are installed on its upper surface. Two workpiece fixing seats 9 form a group, for a total of four groups, which are used to fix the internal tooth groove fixing seats to be ground. Locking screws 10 are spaced apart on the upper surface of the workpiece base 8. A T-shaped clamping block 11, movable along the axial direction of the locking screw, is installed at the upper end of each screw. After the workpiece is placed into the workpiece fixing seat, the T-shaped clamping block 11 is fitted onto the locking screw 10, and the locking nut 12 is tightened to fix the inner tooth groove fixing seat of the tooth groove meshing motion assembly, ensuring that the inner tooth groove fixing seat remains stationary during grinding. Thus, when the adjustment handwheel is manually rotated, it drives the trapezoidal screw to rotate. The rotation of the trapezoidal screw causes the trapezoidal nut to move up and down along the trapezoidal screw axis. The trapezoidal nut, through the trapezoidal nut connector, drives the workpiece base to move up and down along the linear guide rail. The vertical installation position of the inner tooth groove fixing seat of the tooth groove meshing motion assembly can be adjusted according to different grinding specifications to accommodate the installation and fixing of different grinding products. This invention has four fixed installation positions, thus allowing simultaneous grinding of four sets of tooth groove meshing motion assemblies.

[0027] The grinding motion assembly 4 includes an external toothed groove moving seat connecting rod 24, a lower straight connecting rod 25, an open retaining ring 26, a cross-shaped connecting seat 27, an upper straight connecting rod 28, a connecting rod bracket 29, a locking nut 30, a groove connector 31, a connecting pin 32, a linear bearing 33, and a linear guide shaft 34. The linear bearing 33 is fixed to the countersunk shaft hole on the upper surface of the upper support seat by screws. The linear guide shaft 34 is connected and fixed to the upper support seat via the linear bearing 33. The lower end of the linear guide shaft is fixed to the upper surface of the connecting rod bracket 29 by a threaded connection, and the upper end passes through the linear bearing. Four upper straight connecting rods 28 are distributed on the connecting rod bracket 29 and fixed to the connecting rod bracket by the connecting rod locking nuts 30. The upper straight connecting rods 28 and the lower straight connecting rods 25 are fixed together by the cross-shaped connecting seat 27, and the open retaining ring 26 restricts the upper straight connecting rods and the lower straight connecting rods within the cross groove of the cross-shaped connecting seat 27. The connecting rod 24 of the external gear groove moving seat has threads at both ends. The upper thread connects to the internal thread of the next slotted connecting rod, and the lower thread connects to the internal thread hole of the external gear groove moving seat. A rectangular slot is provided at the center of the connecting rod bracket 29 for connecting the drive connecting rod 35 of the grinding drive assembly, facilitating the coordinated movement of the slot connector 31 and the drive connecting rod 35 (grinding drive assembly 5). The lower end of the slot connector is fixed to the middle of the connecting rod bracket by a lock nut, and a connecting pin 32 is provided in the circular hole at the upper end for connecting the drive connecting rod (grinding drive assembly). Through the connecting pin, the movement of the drive connecting rod is transmitted to the connecting rod bracket. At the same time, due to the linear guide shaft, the oscillating motion of the drive connecting rod is converted into the up-and-down reciprocating motion of the connecting rod bracket. When the connecting rod bracket 29 moves up and down along the linear guide shaft 34, the cross-shaped connecting seat 27 can eliminate the coaxiality deviation between the upper slotted connecting rod and the next slotted connecting rod, and the connecting rod of the external gear groove moving seat, so that there will be no jamming or binding during the movement.

[0028] The grinding drive assembly 5 is positioned above the support frame assembly 1 and includes a drive linkage 35, an adjustable output shaft 36, an adjusting shim 37, an adjusting connecting plate 38, a disc-shaped output shaft 39, a reducer 40, and a motor 41. The motor 41 is connected to one side of the reducer 40 via a flange, and the reducer 40 is fixed to the upper support mounting surface with screws. One end of the disc-shaped output shaft 39 is connected to the output shaft of the reducer 40 via a keyway, while the other end has a groove in which the adjustable output shaft 36 is installed. The adjustable output shaft has a grooved circular hole, allowing for a certain radial displacement within the groove on the end face of the disc-shaped output shaft. This displacement is ultimately fixed by the adjusting shim 37 and the adjusting connecting plate 38. The drive linkage 35 has spherical bearings at both ends. One end bearing is connected to the adjustable output shaft 36 and is limited by a lock nut. The other end bearing is connected to the groove connector of the grinding motion assembly 4 via a pin. This connects the grinding drive assembly 5 with the grinding motion assembly 4, and by adjusting the installation position of the adjustable output shaft on the disc-shaped output shaft, the vertical grinding motion distance can be varied to adapt to the grinding of different tooth meshing motion assemblies.

[0029] The toothed groove meshing motion assembly 3 includes an inner toothed groove fixed seat 42 and an outer toothed groove moving seat 43. The left and right halves of the inner toothed groove fixed seat are combined to form an inner toothed groove fixed seat, whose installation position on the workpiece base 8 is determined by the workpiece fixed seat 9, and it is fixed by a T-shaped clamping block 11 and a locking nut 12. The outer toothed groove moving seat is nested inside the inner toothed groove fixed seat, and the two achieve meshing and sliding through a toothed structure. Driven by the vertical reciprocating motion of the connecting rod of the outer toothed groove moving seat, the rotational motion of the grinding drive assembly is converted into the linear reciprocating motion of the outer toothed groove moving seat, thereby achieving precise grinding of the inner toothed groove fixed seat and the outer toothed groove moving seat.

[0030] This invention provides a method for using the above-mentioned automatic grinding machine for multi-station toothed meshing moving components, comprising the following steps: (1) Before the automatic grinding begins, connect the outer tooth groove moving seat 43 of each group of tooth groove meshing motion components 3 to the outer tooth groove moving seat connecting rod 24, and then place the two inner tooth groove fixing seats 42 on the workpiece fixing seat 9 respectively, and fix them by T-shaped clamping block 11 and locking nut 12.

[0031] (2) Manually rotate the adjusting handwheel 14 to adjust the height of the workpiece base 8 so that the two inner tooth groove fixed seats in each group mesh with the outer tooth groove moving seats. Apply grinding paste to the meshing part of the tooth grooves. By changing the installation size and number of adjusting shims 37 on the adjusting connecting plate 38, adjust the radial position of the adjustable output shaft 36 on the disc-shaped output shaft 39 so that the distance range of the adjustable output shaft rotating one revolution to drive the outer tooth groove moving seat to move up and down covers the tooth groove length of the inner tooth groove fixed seat.

[0032] (3) Then the motor 41 is started. Under the deceleration action of the reducer 40, the disc output shaft 39 can obtain a certain speed. The rotational motion of the disc output shaft 39 drives the adjustable output shaft 36 to make an arc motion with the center of the disc output shaft as the center and a certain length as the radius. The upper end of the drive link 35 makes the same arc motion, and the lower end drives the link bracket 29 to make a vertical linear reciprocating motion under the guidance of the linear guide shaft 34. The link bracket 29 passes through four sets of upper I-shaped link 28, cross-shaped connecting seat 27, lower I-shaped link 25, and external tooth groove moving seat connecting rod 24 in sequence, and finally transmits the linear reciprocating motion to the external tooth groove moving seat 43, converting the rotational motion of the motor shaft into the linear motion of the vertical internal tooth groove fixed seat and the external tooth groove moving seat grinding, and performing automatic grinding.

[0033] (4) After the grinding reaches the required time, turn off the motor to complete the grinding of the four sets of toothed meshing motion components.

The other end spherical bearing is connected to the groove connecting piece of the grinding motion assembly via a pin.

8. The automatic grinding machine for multi-station toothed meshing moving components according to claim 1, characterized in that: The toothed groove meshing motion assembly consists of two halves of the inner toothed groove fixed seat combined into one inner toothed groove fixed seat. The installation position of the inner toothed groove fixed seat on the workpiece base is determined by the workpiece fixed seat, and it is fixed by a T-shaped clamping block and a locking nut. The outer toothed groove moving seat is nested inside the inner toothed groove fixed seat, and the two achieve meshing and sliding through the toothed structure. Driven by the vertical reciprocating motion of the connecting rod of the outer toothed groove moving seat, the rotational motion of the grinding drive assembly is converted into the linear reciprocating motion of the outer toothed groove moving seat, thereby realizing the precise grinding of the inner toothed groove fixed seat and the outer toothed groove moving seat.

9. A method of using an automatic grinding machine for a multi-station gear meshing moving assembly as described in any one of claims 1 to 8, characterized in that... Includes the following steps: (1) Before automatic grinding begins, connect the outer tooth groove moving seat of each set of tooth groove meshing motion components to the outer tooth groove moving seat connecting rod, and then place the two inner tooth groove fixing seats on the workpiece fixing seat respectively, and fix them by T-shaped clamping blocks and locking nuts; (2) Manually rotate the adjustment handwheel to adjust the height of the workpiece base so that the two inner tooth groove fixed seats of each group mesh with the outer tooth groove moving seat; add grinding paste to the tooth groove meshing part and adjust the position of the adjustable output shaft so that the distance range of the adjustable output shaft rotating one revolution to drive the outer tooth groove moving seat to move up and down covers the tooth groove length of the inner tooth groove fixed seat. (3) Then start the motor. The motor rotates and drives the reducer, disc output shaft, adjustable output shaft and drive linkage to convert the rotational motion into the linear motion of grinding between the inner tooth groove fixed seat and the outer tooth groove moving seat in the vertical direction. Automatic grinding is carried out. After the grinding reaches the time requirement, the motor is turned off and the four sets of tooth groove meshing motion components complete the grinding.
