Detailed implementation manners

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0030] Embodiment 1 Referring to Figures 1-9 , this is the first embodiment of the present invention. This embodiment provides a surface treatment device for parts used in the production of door locks. The surface treatment device for parts used in the production of door locks includes a fixing component 200 and a flipping component 300. Through the fixing component 200, the effect of efficiently and reliably fixing the door lock housing is achieved. The process does not require manual fixing by workers, greatly simplifying the operation process and reducing labor costs. Through the flipping component 300, the effect of automatically flipping the door lock housing is achieved, which can drive the door lock housing to rotate by 90°, realizing the automatic conversion of different sides.

[0031] The main structure 100 includes an operating table 101. A frame 102 is fixedly connected to the top of the operating table 101. A polishing part 103 is arranged on one side of the inner cavity of the frame 102; and, In the main structure 100, the operating table 101 serves as the basic support of the entire device, the frame 102 provides an installation space for other components, and the polishing part 103 is used for surface polishing treatment of the door lock housing.

[0032] The fixing component 200 includes a rotating shaft 201 located on one side of the polishing part 103. A receiving plate 202 is fixedly connected to one side of the rotating shaft 201. A movable rod 203 is rotatably connected to one side of the receiving plate 202. A guiding block 204 is fixedly connected to the surface of the movable rod 203. A movable sleeve 205 is slidably connected to the surface of the movable rod 203. A guiding groove 206 is formed on the surface of the movable sleeve 205 and is matched with the guiding block 204. Guide wheels 207 are fixedly connected to both sides of the movable sleeve 205. A guide plate 208 is arranged on one side of the guide wheels 207. A guide rail 209 is formed on one side of the guide plate 208 and is matched with the guide wheels 207. A fixing part 210 is arranged on one side of the movable rod 203; and, The fixing component 200 is used to fix the door lock housing. The rotating shaft 201 can drive the bearing plate 202 to rotate. The movable rod 203, the guide block 204, the movable sleeve 205, the guide groove 206, the guide wheel 207, the guide plate 208 and the guide rail 209 cooperate with each other, and can convert the linear motion of the movable sleeve 205 into the rotation of the movable rod 203, so as to drive the fixing member 210 to fix the door lock housing.

[0033] As a key transmission component of the fixing component 200, the rotating shaft 201 drives the bearing plate 202 to rotate through its own rotation, and then realizes the position adjustment of the door lock housing fixed on the bearing plate 202, preparing for the polishing operation on different sides of the subsequent parts. The movable rod 203 is rotatably connected to the bearing plate 202 and can rotate under the action of the movable sleeve 205. Through its own rotation, it drives the fixing member 210 to act, realizing the fixing or loosening of the door lock housing, and playing a key role in the action transmission of the fixing component 200. The guide block 204 is fixed on the surface of the movable rod 203 and cooperates with the guide groove 206 on the movable sleeve 205. When the movable sleeve 205 moves, the guide groove 206 presses the guide block 204, thereby converting the linear motion of the movable sleeve 205 into the rotation of the movable rod 203 and precisely controlling the action of the movable rod 203. The movable sleeve 205 can slide on the surface of the movable rod 203. The guide groove 206 opened on its surface cooperates with the guide block 204, and the guide wheels 207 fixed on both sides cooperate with the guide rail 209 on the guide plate 208. Through this cooperation method, the sliding of itself in the guide rail 209 is converted into the driving force for the rotation of the movable rod 203, while ensuring the stability and accuracy of the movement. The guide wheels 207 are installed on both sides of the movable sleeve 205 and roll in the guide rail 209 of the guide plate 208. On the one hand, the rolling of the guide wheels 207 reduces the friction when the movable sleeve 205 moves, making the movement of the movable sleeve 205 smoother; on the other hand, through the rolling in the guide rail 209, the movement trajectory of the movable sleeve 205 is accurately guided to ensure that the movable sleeve 205 can accurately drive the movable rod 203 to rotate. One side of the guide plate 208 is provided with a guide rail 209, providing a movement track for the guide wheels 207, ensuring that the guide wheels 207 and the movable sleeve 205 connected thereto move along a predetermined trajectory, and further ensuring the accuracy and stability of the action of the entire fixing component 200. The main function of the fixing member 210 is to fix the door lock housing placed on the bearing plate 202, ensuring that the parts will not be displaced during the polishing process and guaranteeing the polishing effect. The flipping component 300 includes a swinging member 301 located on one side of the rotating shaft 201. One side of the swinging member 301 is provided with a rotating member 302, and the other side of the swinging member 301 is provided with a limiting member 303.

[0034] The swinging member 301 is connected to the rotating shaft 201. Through its own swinging, it drives the rotating shaft 201, the receiving plate 202 fixed thereon, and the door lock housing to swing together, changing the attitude of the parts, avoiding interference with the polishing wheel during the subsequent rotation process, and at the same time providing attitude adjustment for the polishing of different sides of the door lock housing. The rotating member 302 cooperates with the rotating shaft 201. Through the meshing of the gear 302a with the limiting tooth 302a-1 and the toothed plate 302b, the rotation of the rotating shaft 201 is realized, and then the door lock housing is driven to rotate, so that different sides of the parts face the polishing wheel in turn, completing the multi-directional polishing process. The limiting member 303 limits the swinging of the swinging member 301 to ensure that the swinging member 301 moves within a specified angular range, ensuring the position accuracy of the door lock housing during the swinging process, preventing the parts from colliding and being damaged with other components due to excessive swinging, and at the same time ensuring the stability and reliability of the device operation.

[0035] In the flipping assembly 300, the flipping of the door lock housing can be realized through the swinging member 301 and the rotating member 302, which is convenient for polishing different sides. At the same time, through the cooperation with the limiting member 303, the stability and accuracy of the flipping process are ensured.

[0036] Embodiment 2 Referring to Figures 1-9 , this is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0037] Specifically, the polishing member 103 includes a connecting plate 103a fixedly connected to one side of the inner cavity of the outer frame 102. The bottom of one side of the connecting plate 103a is fixedly connected with a first polishing wheel 103b, and the top of one side of the connecting plate 103a is fixedly connected with a second polishing wheel 103c. The other side of the inner cavity of the outer frame 102 is fixedly connected with a sliding seat 103d, and one side of the sliding seat 103d is slidably connected with a sliding table 103e.

[0038] The connecting plate 103a fixes the first polishing wheel 103b and the second polishing wheel 103c on one side of the inner cavity of the outer frame 102. The first polishing wheel 103b is located at the bottom of one side of the connecting plate 103a, and the second polishing wheel 103c is located at the top. The two can polish different side positions of the door lock housing. The cooperation of the sliding seat 103d and the sliding table 103e enables the sliding table 103e to slide on the sliding seat 103d, providing a motion basis for driving the frame 210f fixed with the door lock housing to rise or fall subsequently, so as to realize the polishing of different sides.

[0039] The first polishing wheel 103b is installed at the bottom of one side of the connecting plate 103a. There are two groups of the first polishing wheels 103b, and the distance between the two groups is relatively large, which can polish the two short sides of the door lock housing, remove defects, scratches, etc. on the surface of the parts, and improve the flatness and smoothness of the surface of the parts. The second polishing wheel 103c is installed at the top on one side of the connecting plate 103a. There are two sets of the second polishing wheels 103c with a relatively small distance between the two sets, which can polish the two long sides of the door lock housing. Cooperating with the first polishing wheel 103b, it can achieve the comprehensive polishing of the four sides of the door lock housing, ensuring the consistency of the surface quality of the parts.

[0040] The sliding seat 103d is fixed on the other side of the inner cavity of the outer frame 102, providing sliding support for the sliding table 103e, ensuring that the sliding table 103e can slide smoothly up and down along the predetermined direction, providing a stable movement basis for driving the frame 210f fixed with the door lock housing to lift and lower subsequently. The sliding table 103e can slide on the sliding seat 103d. Through connection with other components, it drives the frame 210f and the door lock housing fixed on the frame 210f to rise or fall, enabling the door lock housing to reach the polishing positions of the first polishing wheel 103b and the second polishing wheel 103c in sequence, and achieving the polishing treatment of different sides of the parts.

[0041] Specifically, a slider 205a is fixedly connected to the bottom of the movable sleeve 205, and a sliding groove 205b is formed at the top of the bearing plate 202 and is matched with the slider 205a.

[0042] The slider 205a at the bottom of the movable sleeve 205 is matched with the sliding groove 205b at the top of the bearing plate 202, making the sliding of the movable sleeve 205 on the bearing plate 202 more stable, ensuring that the movable sleeve 205 will not shift during the movement process, thereby ensuring that the subsequent pressing of the guide block 204 through the guide groove 206 enables the movable rod 203 to rotate accurately, and further realizing the reliable fixation of the fixing member 210 to the door lock housing.

[0043] Specifically, a support seat 203a is rotatably connected to the surface of the movable rod 203 through a bearing. The support seat 203a is fixedly connected to the top of the bearing plate 202. A first spring 203b is fixedly connected to one side of the support seat 203a. One side of the first spring 203b is fixedly connected to the movable sleeve 205, and the first spring 203b covers the surface of the movable rod 203.

[0044] The support seat 203a is rotatably connected to the surface of the movable rod 203 through a bearing and fixed to the top of the bearing plate 202, providing stable support for the movable rod 203. The first spring 203b covers the surface of the movable rod 203, is fixed to one side with the support seat 203a, and is fixed to the other side with the movable sleeve 205. When the movable sleeve 205 moves, the first spring 203b can play a buffering and resetting role, ensuring the stability of the rotation and resetting of the movable rod 203, and improving the working reliability of the fixing assembly 200.

[0045] The first spring 203b covers the surface of the movable rod 203, is fixed to the support base 203a on one side, and is fixed to the movable sleeve 205 on the other side. When the movable sleeve 205 moves, the first spring 203b plays a role in buffering and resetting. After the movable sleeve 205 presses the movable rod 203 to rotate, the first spring 203b can make the movable rod 203 and the movable sleeve 205 return to the initial position after the acting force disappears, so as to realize the fixation of the door lock housing.

[0046] Specifically, the fixing member 210 includes a movable table 210a fixedly connected to one side of the movable rod 203. Curved rods 210b are movably connected to the periphery of the movable table 210a. One side of the curved rod 210b is movably connected to a telescopic plate 210c. One side of the telescopic plate 210c is fixedly connected to a fixing plate 210d. The other side of the telescopic plate 210c is slidably connected to a slide rail 210e. One side of the slide rail 210e is fixedly connected to a frame 210f. One side of the frame 210f is slidably connected to the telescopic plate 210c. The frame 210f is fixedly connected to one side of the receiving plate 202.

[0047] The movable table 210a is fixed to one side of the movable rod 203. When the movable rod 203 rotates, it drives the movable table 210a to rotate, thereby causing the curved rods 210b movably connected to the periphery to swing. The swing of the curved rods 210b drives the telescopic plate 210c to slide on the slide rail 210e, so that the fixing plate 210d contacts and fixes to the inner wall of the door lock housing. The frame 210f is fixed to one side of the receiving plate 202, providing a sliding support for the telescopic plate 210c to ensure the stability and reliability of the fixing process.

[0048] The slide rail 210e is fixed to one side of the frame 210f, providing a sliding track for the telescopic plate 210c, ensuring that the telescopic plate 210c can slide smoothly and accurately under the drive of the curved rod 210b, so that the fixing plate 210d can accurately fix the door lock housing. The frame 210f is fixed to one side of the receiving plate 202. On the one hand, it provides an installation basis for the slide rail 210e to ensure the stability of the slide rail 210e; on the other hand, it is used to place the door lock housing that needs surface treatment, and cooperates with other components to realize the functions of fixing the door lock housing and transporting it to the polishing position.

[0049] Specifically, the swinging member 301 includes a swinging shaft 301a hinged to one side of the sliding table 103e. The swinging shaft 301a is rotatably connected to the rotating shaft 201 through a bearing. One side of the swinging shaft 301a is provided with a ball 301b. One side of the ball 301b is provided with a rolling plate 301c. One side of the rolling plate 301c is provided with a convex platform 301d, which cooperates with the ball 301b. The rolling plate 301c is fixedly connected to one side of the sliding seat 103d.

[0050] The swing shaft 301a is hinged to one side of the sliding table 103e and is rotationally connected to the rotating shaft 201 through a bearing, providing a rotational basis for the swing of the door lock housing. The ball 301b is arranged on one side of the swing shaft 301a, and the boss 301d on the rolling plate 301c cooperates with the ball 301b. When the sliding table 103e drives the frame 210f to rise, the ball 301b, under the action of the boss 301d, causes the swing shaft 301a to drive the frame 210f and the door lock housing to swing, avoiding interference between the subsequent rotation of the door lock housing and the polishing wheel.

[0051] When the ball 301b contacts the boss 301d, the swing shaft 301a drives the rotating shaft 201, the bearing plate 202, and the door lock housing to swing together, changing the posture of the parts, avoiding interference with the polishing wheel during the subsequent rotation process, and at the same time providing a basis for posture adjustment for the polishing of different sides of the door lock housing. Ball 301b: Arranged on one side of the swing shaft 301a, cooperating with the boss 301d on the rolling plate 301c. When the sliding table 103e rises, the ball 301b, under the action of the boss 301d, converts the upward movement of the sliding table 103e into the swinging power of the swing shaft 301a, enabling the swing shaft 301a to accurately drive the parts to swing, and the rolling of the ball 301b reduces the friction force, ensuring the smoothness of the swinging process. The rolling plate 301c is fixed to one side of the sliding seat 103d, and the boss 301d on its surface cooperates with the ball 301b. Through the special shape and position setting of the boss 301d, when the sliding table 103e rises, the ball 301b is accurately pushed, thereby driving the swing shaft 301a to swing, providing an accurate driving force for the posture adjustment of the door lock housing.

[0052] Specifically, the rotating part 302 includes a gear 302a fixedly connected to the surface of the rotating shaft 201. One side of the sliding table 103e is fixedly connected with a limit tooth 302a-1, and the limit tooth 302a-1 cooperates with the gear 302a. One side of the boss 301d is provided with a toothed plate 302b, which also cooperates with the gear 302a, and the toothed plate 302b is fixedly connected to the other side of the sliding seat 103d.

[0053] The gear 302a is fixed on the surface of the rotating shaft 201, and both the limit tooth 302a-1 and the toothed plate 302b cooperate with the gear 302a. When the frame 210f and the door lock housing swing, the gear 302a swings to the position of the toothed plate 302b and meshes with it. As the door lock housing rises, the gear 302a rotates under the action of the toothed plate 302b, driving the rotating shaft 201 and the door lock housing to rotate by 90°, thereby realizing the conversion of different sides of the door lock housing, facilitating the polishing of the other two sides, and improving the comprehensiveness and efficiency of polishing.

[0054] The limiting tooth 302a-1 can limit the gear 302a when the frame 210f and the door lock housing do not swing, thereby increasing the stability of the frame 210f and the door lock housing and improving the polishing effect.

[0055] Specifically, the limiting member 303 includes a bent plate 303a fixedly connected to one side of the swing shaft 301a. One side of the bent plate 303a is hinged with a second spring 303b, and one side of the second spring 303b is hinged with the slide table 103e.

[0056] The bent plate 303a is fixed on one side of the swing shaft 301a. One side of the second spring 303b is hinged with the bent plate 303a, and the other side is hinged with the slide table 103e. The second spring 303b can provide a reset pulling force after the swing shaft 301a swings, ensuring that the swing shaft 301a can return to the initial position after swinging, preparing for the next swing and rotation operations, improving the working efficiency and stability of the device, and at the same time reducing the wear between components.

[0057] And when the swing shaft 301a swings back to the initial position, the limiting tooth 302a-1 meshes with the gear 302a, thereby preventing the rotating shaft 201 from driving the frame 210f and the door lock housing to rotate.

[0058] Specifically, the limiting member 303 further includes a limiting post 303c disposed on the other side of the bent plate 303a. A groove 303d is formed on the other side of the rolling plate 301c and is matched with the limiting post 303c.

[0059] The limiting post 303c is disposed on the other side of the bent plate 303a. The groove 303d on the other side of the rolling plate 301c is matched with the limiting post 303c. During the lifting process of the swing shaft 301a, the limiting post 303c is inserted into the groove 303d to limit the swing shaft 301a, ensuring the stability of the swing shaft 301a during the lifting process, preventing it from shaking or shifting, and thus ensuring the accuracy and reliability of the swinging and rotating processes of the door lock housing and improving the polishing accuracy.

[0060] Specifically, one side of the limiting post 303c is slidably connected to a limiting cylinder 303c-1, and one side of the limiting cylinder 303c-1 is fixedly connected to the bent plate 303a.

[0061] One side of the limiting post 303c is slidably connected to the limiting cylinder 303c-1, and the limiting cylinder 303c-1 is fixed on one side of the bent plate 303a. When the swing shaft 301a swings and the limiting post 303c disengages from the groove 303d, the limiting post 303c can slide into the limiting cylinder 303c-1 to avoid interference, ensuring the smoothness of the swinging process of the swing shaft 301a, making the operation of the device more stable and reliable, and reducing the probability of failure.

[0062] During use, place the door lock housing on the frame 210f. The sliding table 103e starts to rise on the sliding seat 103d, driving the frame 210f to rise synchronously. During this process, the slider 205a at the bottom of the movable sleeve 205 slides within the chute 205b at the top of the receiving plate 202, ensuring the stable movement of the movable sleeve 205. The guide wheels 207 on both sides of the movable sleeve 207 roll within the guide rails 209 of the guide plate 208, driving the movable sleeve 205 to move along the trajectory of the guide rail 209. The guide groove 206 on the surface of the movable sleeve 205 presses against the guide block 204 on the surface of the movable rod 203, causing the movable rod 203 to rotate under the support of the support seat 203a. The rotation of the movable rod 203 drives the rotation of the movable table 210a, and the curved rods 210b movably connected around the movable table 210a swing accordingly. The swing of the curved rod 210b pushes the telescopic plate 210c to slide on the slide rail 210e, finally making the fixed plate 210d in close contact with the inner wall of the door lock housing, completing the fixation of the door lock housing. This process automatically completes the fixation of the door lock housing, avoiding the cumbersome operation of manual fixation, corresponding to the problem of labor-consuming and complex operation in manual fixation in the background technology.

[0063] As the frame 210f continues to rise, both sides of the door lock housing move to the first polishing wheel 103b. The first polishing wheel 103b is installed at the bottom of one side of the connecting plate 103a, with two groups and a relatively large spacing, capable of polishing the two short sides of the door lock housing, removing surface defects, and improving flatness and smoothness. At this time, the door lock housing undergoes preliminary polishing in a fixed state, solving the complex process problem of manually moving parts to the polishing position in the background technology.

[0064] When the frame 210f rises to a specific height, the ball 301b on the swing shaft 301a contacts the boss 301d on the rolling plate 301c. Under the action of the boss 301d, the swing shaft 301a drives the rotating shaft 201, the receiving plate 202, and the door lock housing to swing. The swing shaft 301a is hinged to one side of the sliding table 103e and is rotationally connected to the rotating shaft 201 through a bearing, providing a basis for the swing. This swinging action avoids the subsequent interference between the rotation of the door lock housing and the polishing wheel, and at the same time provides attitude adjustment for the polishing of different sides of the door lock housing, solving the problem of manually adjusting the orientation of parts for polishing different sides in the background technology.

[0065] After the housing 210f and the door lock housing swing, the gear 302a on the surface of the rotating shaft 201 swings to the toothed plate 302b and meshes with it. As the door lock housing continues to rise, the gear 302a rotates under the action of the toothed plate 302b, driving the rotating shaft 201 and the door lock housing to rotate by 90°. At this time, the other two sides of the door lock housing move to the second polishing wheel 103c. The second polishing wheel 103c is installed at the top of one side of the connecting plate 103a, and there are two groups with a small spacing, which polish the two long sides of the door lock housing. Cooperating with the first polishing wheel 103b, it realizes the comprehensive polishing of the four sides of the door lock housing. When not swinging, the limiting tooth 302a-1 limits the gear 302a to ensure the stability of the housing 210f and the door lock housing. This step realizes the automatic conversion of different sides of the parts and comprehensive polishing, avoiding the cumbersome process of manual disassembly, re-fixing the parts for polishing different sides.

[0066] Embodiment 3 Refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 9 This is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0067] Specifically, there are two groups of guide plates 208, which are evenly distributed on both sides of the guide wheel 207. The guide plates 208 are fixedly connected to the inner cavity of the operating table 101 through the mounting seats at the bottom.

[0068] The two groups of guide plates 208 are evenly distributed on both sides of the guide wheel 207 and are fixed in the inner cavity of the operating table 101 through the bottom mounting seats, providing a stable and accurate movement track for the guide wheel 207. The guide plates 208 on both sides can constrain the guide wheel 207 from different directions, preventing it from shifting during movement, ensuring that the movable sleeve 205 moves along a predetermined trajectory, and thus ensuring the accuracy and stability of the operation of the fixing assembly 200.

[0069] Specifically, the surface of the guide block 204 is arc-shaped and its surface is polished.

[0070] The surface of the guide block 204 is arc-shaped and polished, which can cooperate more smoothly with the guide groove 206 on the movable sleeve 205. The arc-shaped design reduces the contact stress concentration between the guide block 204 and the guide groove 206, and the polishing treatment further reduces the friction between the two, making the process of the guide groove 206 pressing and driving the movable rod 203 to rotate more stable and efficient when the movable sleeve 205 moves.

[0071] Specifically, there are two groups of second springs 303b, which are evenly distributed on one side of the bending plate 303a.

[0072] Two groups of second springs 303b evenly distributed on one side of the bending plate 303a can provide more balanced and stable reset pulling force after the swing shaft 301a swings. Compared with a single group of springs, the two groups of springs can better ensure that the swing shaft 301a accurately returns to the initial position after swinging, prepare for the next swing and rotation operations, and improve the stability and reliability of the device operation.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
