Description

Technical Field

[0001] This invention relates to the field of lock deburring technology, and more specifically, to a lock deburring device. Background Technology

[0002] Child locks develop a certain amount of burrs after die-casting. These burrs significantly affect the lock's performance and can easily injure children. Therefore, the lock cylinder needs to be deburred before assembly. Existing deburring devices lack protective mechanisms when deburring door locks and cylinders. This causes debris to fly during burr removal, impacting the working environment and posing a risk of injury to workers.

[0003] To address the aforementioned issues, Chinese Patent No. CN223313672U discloses a deburring surface treatment device for automotive door locks, comprising a worktable, a bracket fixedly mounted on the upper surface of the worktable, a rotating clamp rotatably mounted on the front surface of the bracket, a grinding component fixedly mounted on the front surface of the bracket, a sliding groove formed on the front surface of the bracket, a cover plate slidably mounted on the outer surface of the bracket, a sliding plate fixedly inserted between the front and rear inner walls of the cover plate, two connecting plates fixedly mounted on the left and right surfaces of the cover plate, and two telescopic cylinders fixedly mounted on the left and right sides of the lower surface of the worktable.

[0004] The above solution, through the coordination of the worktable, support, rotating fixture, grinding component, slide, cover plate, slide plate, connecting plate, telescopic cylinder, controller, and sensor, can cover the grinding components, preventing debris from splashing laterally and ensuring a safe working environment. However, in this solution, the debris, after being covered by the cover plate, will eventually fall onto the worktable and be blown down and collected in a collection box by the bellows. However, the worktable has several protruding structures, such as the support and the output rod of the telescopic cylinder. These structures can easily cause debris to accumulate during the collection process, ultimately affecting the normal use of the lifting structure and the collection of debris.

[0005] Therefore, a solution needs to be proposed to address this problem. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a lock burr removal device. By arranging the driving devices on the outside of the support frame, the workbench is kept flat, allowing for more thorough and efficient cleaning of debris.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a lock burr removal device, comprising a workbench, a bracket fixedly mounted on the upper surface of the workbench, a rotating clamp rotatably mounted on the front surface of the bracket, cleaning components on both sides of the workbench, a grinding component on the front surface of the bracket, a protective cover slidably connected to the inner wall of the bracket, the protective cover covering the rotating clamp and the grinding component, a driving device for raising and lowering the protective cover on the outer wall of the bracket, extension rods fixedly connected to both sides of the outer wall of the protective cover, a through groove for the extension rods to pass through and move on the inner wall of the bracket, a folding baffle fixedly connected to one end on both the upper and lower sides of the extension rod, and the other end of the folding baffles on both sides being fixedly connected to the inner wall of the through groove.

[0008] By adopting the above technical solution, when this equipment performs deburring operations on locks, the protective cover can be moved upward along the support by the driving device until the upper end face of the driving device is in contact with the inner top wall of the support. The rotating clamping parts and the grinding parts are covered inside the protective cover. The grinding debris is blocked by the protective cover and cannot fly outward. Most of the debris blocked by the protective cover will eventually fall onto the worktable. After the deburring operation is completed, the protective cover is lowered by the driving device, exposing the rotating clamping parts to the outside. During the raising and lowering of the protective cover, the extension rod will rise and fall along the through groove. The driving device is set outside the support and will not form a protruding structure on the worktable. The surface of the worktable will always remain flat, and debris will not accumulate in the gaps of the structure. The cleaning component can smoothly sweep and collect the debris on the worktable, achieving more thorough and efficient debris cleaning. At the same time, the folding baffles on the upper and lower sides of the extension rod will extend and fold synchronously with the movement of the extension rod, always blocking the opening of the through groove, reducing the debris flying out from the gap of the through groove, and ensuring the overall protective effect.

[0009] The invention is further configured such that: the grinding component includes two grinding discs symmetrically arranged on both sides of the rotating clamp component, and mounting plates are fixedly connected to the outer walls of the grinding discs on both sides. Fastening holes are provided on the mounting plates, and fastening grooves corresponding to the positions of the fastening holes are provided on the upper end face of the bracket. Fastening bolts are inserted into the fastening holes and fastening grooves.

[0010] By adopting the above technical solution, the two grinding discs are respectively attached to the inner top wall of the bracket through the mounting plate. After adjusting the distance between the two grinding discs to match the locks of different sizes, the fastening bolts can be screwed into the fastening holes and fastening grooves to fix the position of the grinding discs. This makes it convenient to adjust the grinding position according to the processing requirements and improves the adaptability of the equipment.

[0011] The invention is further configured such that: two sets of striking components are symmetrically arranged on the outer wall of the protective cover; each set of striking components includes a fixed frame and a rotating rod rotatably connected to the inner wall of the fixed frame; the fixed frame is fixedly connected to the outer wall of the protective cover; a motor for driving the rotating rod to rotate is fixedly installed on the outer wall of the fixed frame; a driving rod is provided on the outer wall of the rotating rod, one end of which is fixedly connected to the driving rod; and a striking roller is fixedly connected to the other end of the driving rod. The striking roller is used to strike the outer wall of the protective cover.

[0012] By adopting the above technical solution, after the deburring and grinding operation is completed, the motor can be turned on to drive the rotating rod to rotate back and forth. The rotating rod will drive the striking roller to reciprocate, so that the striking roller intermittently strikes the outer wall of the protective cover, causing the debris adhering to the inner wall of the protective cover to be dislodged by vibration and fall onto the workbench, reducing the residue of debris and further improving the thoroughness of debris cleaning.

[0013] The present invention is further configured such that: the driving device includes two sets of electric push rods, both sets of electric push rods are fixedly installed on the upper end face of the bracket, the upper end face of the bracket is provided with a through hole through which the output end of the electric push rod passes, and the output ends of the electric push rods on both sides are fixedly connected to the upper end face of the extension rods on both sides after passing through the through hole.

[0014] By adopting the above technical solution, starting the electric push rod can drive the extension rod to rise and fall along the through groove through its output end, thereby driving the entire protective cover to rise and fall along the bracket. The structure is simple and can stably control the rising and falling range of the protective cover. Moreover, both sets of electric push rods are set at the upper end of the bracket, which will not form a protruding structure on the worktable surface, ensuring that the worktable surface is flat.

[0015] The present invention is further configured such that: the driving device includes two symmetrically distributed convex plates and a lead screw rotatably connected to the convex plates on both sides; both convex plates are fixedly connected to the outer wall of the bracket; a motor for driving the lead screw to rotate is fixedly installed on one side of the convex plate; a nut seat is threadedly fitted on the lead screw; and the nut seat is fixedly connected to the side wall of the extension plate on one side.

[0016] By adopting the above technical solution, starting motor 2 can drive the lead screw to rotate. When the lead screw rotates, it will drive the nut seat to move along the lead screw axis, and then drive the protective cover to rise and fall along the bracket through the extension rod. The transmission process is stable and controllable, and the entire driving device is set on the outer wall of the bracket, which will not form a protruding structure on the worktable surface, ensuring that the worktable surface is flat.

[0017] The present invention is further configured such that: a limiting rod is fixedly connected between the two convex plates, and a limiting groove is provided on the nut seat for the limiting rod to pass through.

[0018] By adopting the above technical solution, the limiting rod can limit the movement of the nut seat, preventing the nut seat from rotating with the lead screw, and making the nut seat more stable during the lifting and lowering process.

[0019] The present invention is further configured such that: the surface of the folding baffle is provided with a plurality of folding patterns arranged in an array along the length direction, and the folding baffle is wavy after being folded along the folding patterns.

[0020] By adopting the above technical solution, the folding pattern allows the folding baffle to extend and fold more smoothly with the movement of the extension rod, making it less prone to jamming when the extension rod moves. At the same time, it always maintains the blocking effect on the opening of the through groove, further reducing the possibility of debris flying out from the gap of the through groove.

[0021] In summary, the present invention has the following beneficial effects: This invention, by placing all the driving devices on the outside of the support, keeps the workbench surface flat, preventing debris from accumulating in structural gaps. The cleaning components can smoothly sweep and collect debris from the workbench, achieving more thorough and efficient debris cleaning. At the same time, the folding baffles on the upper and lower sides of the extension rod will extend and fold synchronously with the movement of the extension rod, always blocking the opening of the through slot, reducing debris flying out from the gaps in the through slot, ensuring the overall protective effect, and meeting actual usage needs.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] Example 1: A lock burr removal device, such as Figure 1 As shown, the system includes a workbench 1, with a bracket 2 fixedly mounted on its upper surface. A rotating clamp 3 is rotatably mounted on the front surface of the bracket 2. The rotating clamp 3 includes a rotating frame rotatably connected to the inner top wall of the bracket 2 and a drive motor for driving the rotating frame to rotate. The drive motor is fixedly mounted on the upper end face of the bracket 2. Two sets of symmetrically distributed telescopic rods are fixedly mounted on the rotating frame, and clamping plates are fixedly connected to the output ends of both sets of telescopic rods.

[0029] Cleaning components 4 are provided on both sides of the workbench 1. Each cleaning component 4 includes a collection box fixedly installed on one side of the workbench 1. A filter plate is slidably mounted on the upper surface of the collection box, and a handle is fixedly connected to the upper surface of the filter plate. A feed inlet is provided on the right surface of the collection box, and a slot is provided on the upper surface of the collection box. An air box is fixedly installed on the other side of the workbench 1. The specific structure and working principle of the cleaning component 4 have been described in detail in the prior art. This application has not modified this part of the structure and will not be described in detail here.

[0030] The front surface of the bracket 2 is provided with a grinding element, which includes two grinding discs 5 symmetrically arranged on both sides of the rotating clamp 3. Mounting plates are fixedly connected to the outer walls of both grinding discs 5, and fastening holes are provided on the mounting plates. A fastening groove corresponding to the position of the fastening hole is provided on the upper end face of the bracket 2, and fastening bolts 10 pass through the fastening hole and the fastening groove.

[0031] A protective cover 6 is slidably connected to the inner wall of the bracket 2, covering the rotating clamp 3 and the grinding part. Extension rods 7 are fixedly connected to both sides of the outer wall of the protective cover 6, and a through groove 8 is provided on the inner wall of the bracket 2 for the extension rods 7 to pass through and move. Folding baffles 9 are provided on both the upper and lower sides of the extension rods 7, with one end fixedly connected. The other end of each folding baffle 9 is fixedly connected to the inner wall of the through groove 8. The surface of the folding baffles 9 has several folding patterns arranged in an array along its length, and the folding baffles 9 become wavy after being folded along the folding patterns.

[0032] Two sets of striking components are symmetrically arranged on the outer wall of the protective cover 6. Each set of striking components includes a fixed frame 11 and a rotating rod 12 rotatably connected to the inner wall of the fixed frame 11. The fixed frame 11 is fixedly connected to the outer wall of the protective cover 6. A motor for driving the rotating rod 12 to rotate is fixedly installed on the outer wall of the fixed frame 11. A driving rod 13 is provided on the outer wall of the rotating rod 12, one end of which is fixedly connected to the driving rod 13. The other end of the driving rod 13 is fixedly connected to a striking roller 14, which is used to strike the outer wall of the protective cover 6.

[0033] The outer wall of the bracket 2 is equipped with a driving device for raising and lowering the protective cover 6. The driving device includes two sets of electric push rods 15, both of which are fixedly installed on the upper end face of the bracket 2. The upper end face of the bracket 2 has through holes through which the output ends of the electric push rods 15 pass. After passing through the through holes, the output ends of the electric push rods 15 on both sides are fixedly connected to the upper end faces of the extension rods 7 on both sides.

[0034] Working principle: When this equipment deburrs locks, first place the lock to be processed between two clamping plates, start the telescopic rod to move the clamping plates, clamp and fix the lock, adjust the position of the two grinding discs 5 to match the size of the lock, and then screw in the fastening bolts 10 to complete the fixation.

[0035] Subsequently, the output end of the electric push rod 15 retracts, causing the extension rod 7 and the protective cover 6 to rise along the bracket 2, enclosing the rotating clamp 3 and the grinding parts inside the protective cover 6. The drive motor of the rotating clamp 3 is started to rotate the lock. During the rotation of the lock, it contacts the grinding discs 5 on both sides, thus completing the burr grinding operation.

[0036] The grinding debris is blocked by the protective cover 6 and cannot fly outward. Most of the debris eventually falls onto the flat workbench 1. The folding baffles 9 on the upper and lower sides of the extension rod 7 fold or unfold as the extension rod 7 rises and falls, always blocking the opening of the through groove 8, reducing the amount of debris flying out from the gaps in the through groove 8, and ensuring the protective effect. After the deburring operation is completed, the motor is turned on to drive the rotating rod 12 to rotate back and forth. The driving rod 13 drives the striking roller 14 to intermittently strike the outer wall of the protective cover 6, causing the debris adhering to the inner wall of the protective cover 6 to be shaken off and fall onto the workbench 1. Then, the cleaning component 4 is activated to smoothly sweep and collect the debris on the workbench 1. Since the driving device is located above the support 2 and there are no protruding structures on the surface of the workbench 1, the debris will not accumulate in the gaps, making the cleaning more thorough and efficient, meeting the actual use needs.

[0037] Example 2: Compared with Example 1, Example 2 differs in that the structure of the driving device is different, such as... Figure 2 As shown, in Embodiment 2, the driving device includes two symmetrically distributed convex plates 16 and a lead screw 17 rotatably connected to the convex plates 16 on both sides. Both convex plates 16 are fixedly connected to the outer wall of the bracket 2. A second motor 18 for driving the lead screw 17 to rotate is fixedly installed on one convex plate 16. The second motor 18 is a servo motor, and the output shaft of the second motor 18 is drivenly connected to one end of the lead screw 17. A nut seat 19 is threadedly connected to the lead screw 17, and the nut seat 19 is fixedly connected to the side wall of the extension plate on one side.

[0038] A limiting rod 20 is fixedly connected between the two protruding plates 16, and a limiting groove is provided on the nut seat 19 for the limiting rod 20 to pass through.

[0039] Working principle: The starting motor 18 drives the lead screw 17 to rotate. Under the limiting action of the limiting rod 20, the rotation of the lead screw 17 will drive the nut seat 19 to move axially along the lead screw 17, which in turn drives the protective cover 6 to rise and fall along the bracket 2 through the extension rod 7, thereby achieving stable adjustment of the position of the protective cover 6. The entire driving device is set on the outer wall of the bracket 2, and will not form a protruding structure on the surface of the worktable 1, which can always ensure that the surface of the worktable 1 is flat, which facilitates smooth cleaning of debris. The rest of the working process is the same as in Embodiment 1, which can also achieve thorough and efficient debris cleaning and ensure good protective effect.

[0040] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
