Description

Technical Field

[0001] This utility model belongs to the technical field of deburring devices, specifically relating to a deburring device for hardware parts. Background Technology

[0002] Burrs often appear on metal parts after machining. These burrs can lead to a range of problems, including dimensional deviations, assembly difficulties, premature wear of parts, and potential safety hazards. Therefore, deburring devices are commonly used to remove burrs from metal parts.

[0003] The deburring device for metal stamping parts disclosed in authorization announcement number CN219837263U clamps the metal parts with two clamping plates of a clamping mechanism. A cylinder then drives a motor to move downwards, removing burrs through a deburring plate on the motor. However, the clamping mechanism of the aforementioned device is only suitable for products with regular shapes, and is not suitable for products like... Figures 1-2 For hardware parts with irregular shapes in the middle and thin plates on both sides, the clamping mechanism described above will result in unstable clamping and poor clamping and fixing effect. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a deburring device for hardware parts.

[0005] To achieve the above objectives, this utility model discloses a hardware deburring device, including a back plate and a support component, a positioning component and a deburring component fixedly connected to the back plate, wherein the positioning component and the deburring component are located above the support component;

[0006] The supporting component includes a material support plate, which is fixedly connected to the back plate. The bottom of the material support plate has a clearance space, and a first clearance hole is provided in the middle of the material support plate. The first clearance hole penetrates the top and bottom surfaces of the material support plate. The top surface of the material support plate is recessed at the edge of the first clearance hole to form a slot, which is used to limit and cooperate with the thin plate of the hardware.

[0007] The positioning component includes a first driving device and a positioning element. The first driving device is fixedly connected to the back plate, and the positioning element is fixedly connected to the output end of the first driving device. The bottom of the positioning element is used to abut against and cooperate with the hardware.

[0008] The deburring assembly includes a second driving device and a deburring component connected to the driving device. The second driving device is used to drive the deburring component to move in order to remove burrs from the hardware.

[0009] Furthermore, the first clearance hole extends to the front side of the material support plate.

[0010] Furthermore, the second driving device is a vertically arranged telescopic cylinder, the telescopic cylinder has a telescopic rod, the deburring part is a punch, and the top end of the deburring part is radially expanded outward to form a snap-fit ​​part;

[0011] The deburring assembly further includes a pushing block and a fixing block. The pushing block is fixedly connected to the bottom end of the telescopic rod. The fixing block has a countersunk through hole that is larger at the top and smaller at the bottom. After the deburring part passes through the countersunk through hole, the snap-fit ​​part is engaged in the countersunk through hole. The fixing block is fixedly connected to the bottom surface of the pushing block. The top surface of the deburring part is matched with the bottom surface of the pushing block.

[0012] Furthermore, the deburring assembly also includes a guide plate, which is fixedly connected to the back plate, and the guide plate is provided with guide holes that cooperate with the deburring component.

[0013] Furthermore, the guide plate is provided with a second clearance hole, which is arranged opposite to the first clearance hole.

[0014] Furthermore, each of the burr removal components is provided with a plurality of the deburring elements.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The bottom of the support plate has a clearance space, and a first clearance hole is provided in the middle of the support plate. The first clearance hole and the clearance space can accommodate the middle position of the hardware. The top surface of the support plate is recessed at the edge of the first clearance hole to form a groove. The groove can engage with the thin plate of the hardware to limit its position. In other words, the thin plate of the hardware is placed in the groove and restricted in position, thereby achieving initial fixation of the hardware. The bottom of the positioning part of the positioning component positions the hardware, and finally fixes the hardware to the support plate.

[0019] The hardware is supported and positioned stably on the support plate by using the clearance space at the bottom of the support plate, the clearance hole on the support plate, and the limiting design of the slot on the support plate.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1-2 The hardware component 100 has an irregular structure. Specifically, the middle section of the hardware component 100 has an irregular structure, while the two sides are thin plate structures 110. This type of hardware component 100 uses an existing deburring device, which has poor fixing effect and affects the deburring effect.

[0035] In the aforementioned hardware component 100, the locations where burrs need to be removed are the holes 111 provided on the thin plate 110, such as... Figures 1-2 Specifically, each thin plate 110 has three holes 111, and deburring is required in each hole 111. This embodiment provides a deburring device for this hardware component. See also... Figures 3-7 The device includes a back plate 200 and an upper support assembly 300, a positioning assembly 400, and two sets of deburring assemblies 500 fixedly connected to the front side of the back plate 200. The support assembly 300 supports the hardware parts, and the positioning assembly 400 and the deburring assembly 500 are located above the support assembly 300. The positioning assembly 400 is located in the middle and is used to position and fix the hardware parts. There are two deburring assemblies 500, which are located on both sides of the positioning assembly 400.

[0036] Specifically, the supporting component 300 includes a support plate 310, which is fixedly connected to the back plate 200. The bottom of the support plate 310 has a clearance space 311, and a first clearance hole 312 is provided in the middle of the support plate 310, penetrating the top and bottom surfaces of the support plate 310. The clearance design of the bottom clearance space 311 and the first clearance hole 312 on the support plate 310 allows for clearance in the middle of the hardware component, enabling the thin plates on both sides of the hardware component to be placed stably on the support plate 310. The top surface of the support plate 310 is recessed at the edge of the first clearance hole 312 to form a groove 313. The shape of the groove 313 is the same as that of the thin plates on both sides of the hardware component, and it is used to limit the movement of the thin plates on both sides of the hardware component. In other words, after the thin plates on both sides of the hardware component are placed in the groove 313, their position is restricted, thereby limiting the horizontal movement capability of the hardware component. The positioning assembly 400 includes a first driving device 410 and a positioning member 420. The first driving device 410 is fixedly connected to the back plate 200, and the positioning member 420 is fixedly connected to the output end of the first driving device 410. The bottom of the positioning member 420 is used to abut against the hardware. The deburring assembly 500 includes a second driving device 510 and a deburring member 520 connected to the driving device. The second driving device 510 is used to drive the deburring member 520 to move to remove burrs from the hardware.

[0037] When using the above-described device to remove burrs, the hardware is placed on the support plate 310, with the thin plates on both sides of the hardware locked in the slots 313 of the support plate 310, thereby restricting the horizontal movement of the hardware. Next, the positioning member 420 of the positioning assembly 400 moves downwards to abut against the top surface of the hardware (only contacting the top surface of the hardware, without applying pressure), ultimately fixing the hardware stably and reliably on the support plate 310. Subsequently, the second drive device 510 drives the deburring member 520 to move to remove the burrs from the hardware. After deburring, the first drive device 410 drives the positioning member 420 to reset, and the second drive device 510 drives the deburring member 520 to reset, after which the processed hardware can be removed.

[0038] In this embodiment, the first clearance hole 312 extends to the front side of the material support plate 310. In this way, the hardware can be placed on the material support plate 310 from the front top, without having to place the hardware in a position directly opposite the first clearance hole 312 before placing it on the material support plate 310, which makes loading and unloading convenient.

[0039] In this embodiment, the second driving device 510 is a vertically arranged telescopic cylinder, such as a pneumatic cylinder. The telescopic cylinder has a telescopic rod 511, and the deburring component 520 is a punch. The cross-sectional shape and size of the punch are adapted to the cross-sectional shape and size of the hole to be deburred. When deburring, the telescopic cylinder drives the punch to move downward, and the punch punches into the hole, thereby cutting off the burr in the hole.

[0040] The deburring component 520 has a radially outwardly expanding top end forming a snap-fit ​​portion 521. The deburring assembly 500 also includes a pushing block 530 and a fixing block 540. The pushing block 530 is fixedly connected to the bottom end of the telescopic rod 511 by bolts. The fixing block 540 has a countersunk through hole 541, which is larger at the top and smaller at the bottom. After the deburring component 520 passes through the countersunk through hole 541, the snap-fit ​​portion 521 is engaged in the countersunk through hole 541. The fixing block 540 is fixedly connected to the bottom surface of the pushing block 530, so that the top surface of the deburring component 520 is pressed and limited by the bottom surface of the pushing block 530, and finally the deburring component 520 is fixedly connected to the fixing block 540. The deburring component 520 is fixedly connected to the second driving device 510 by the pushing block 530 and the fixing block 540. The structure is simple and easy to assemble. In this embodiment, each side of the thin plate of the hardware component has three holes, and correspondingly, three deburring components 520 are required. The aforementioned fixing block 540 only needs to be provided with three countersunk through holes 541 to connect the three deburring parts 520, without the need to provide three fixing blocks 540 to connect the three deburring parts 520 respectively, thus simplifying the structure.

[0041] In this embodiment, the deburring component 520 is a punch with a slender structure. There is an assembly gap between the punch and the countersunk through-hole 541, which can easily cause wobbling during actual use, resulting in poor stability and difficulty in accurately aligning with the holes in the hardware, potentially damaging the hardware and causing deformation. To address this, the deburring assembly 500 also includes a guide plate 550, which is fixedly connected to the back plate 200. The guide plate 550 has guide holes 551, the cross-sectional shape and number of which are adapted to the cross-sectional shape and number of the deburring component 520. This allows the deburring component 520 to move stably up and down along the guide holes 551, improving its rigidity and stability, ensuring stable alignment with the holes in the hardware, improving the deburring effect, and reducing product damage and deformation.

[0042] To facilitate the loading and unloading of hardware parts, a second clearance hole 552 is provided on the guide plate 550, corresponding to the first clearance hole 312, opposite to the material support plate 310. The second clearance hole 552 not only facilitates loading and unloading but also allows the positioning component 400 to be avoided, preventing interference between the positioning component 400 and the guide plate 550 when it moves downwards.

[0043] In this embodiment, the slot 313 is sized to support the holes in the thin metal sheet. In other words, the holes on the thin metal sheet that need deburring are supported by the slot 313 of the support plate 310. The bottom of the slot 313 has vertically penetrating through holes 314, the number and position of which correspond one-to-one with the number and position of the deburring parts 520. The slot 313 of the support plate 310 can support the metal parts, which significantly reduces the deformation of the metal parts during deburring and protects the product. The through holes 314 allow the deburring parts 520 to pass through the support plate 310, preventing interference between the deburring parts 520 and the support plate 310, and also allowing the punched burrs to fall off, facilitating burr removal.

[0044] In this embodiment, the first driving device 410 is also a telescopic bar, specifically a cylinder. The bottom of the positioning member 420 is used to limit the upper surface of the hardware, thereby fixing the hardware on the support plate 310. Therefore, the bottom surface of the positioning member 420 only needs to be able to limit the vertical movement of the hardware, and its specific shape can be designed as needed.

[0045] In this embodiment, the supporting component 300 further includes two support plates 320, which are respectively fixedly connected to the bottom sides of the material support plate 310. The bottom of the two support plates 320 is flush with the bottom of the back plate 200. The two back plates 200 of the supporting component 300 not only support the material support plate 310, improving its stability and reliability, but also form a stable bottom support structure with the back plates 200, allowing it to be placed stably on the workbench.

[0046] In this embodiment, the bottom of the support plate 320 of the base plate 600 of the back plate 200 is connected to the base plate 600, and the device is further stabilized on the workbench through the base plate 600.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
