Description

Technical Field

[0001] This utility model relates to the field of fully automatic tack-scraping machine technology, and in particular to an automatic tack-scraping device. Background Technology

[0002] In related technologies, after the mobile phone mid-plate is die-cast, it needs to be deburred using a deburring machine. A deburring machine typically uses a displacement actuator to drive a scraper close to the workpiece and move it along the desired deburring position, using the scraper to remove the burrs adhering to the workpiece surface. However, the inventors discovered in actual production that the scraper of the deburring machine is fixedly mounted on the displacement actuator. For workpieces with poor thickness precision, this can easily lead to overcutting of thicker areas and insufficient scraping of thinner areas. This results in scratches and residual burrs during deburring, severely impacting the reliability and production yield of the deburring operation.

[0003] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 7 The automatic burr scraping device 100 provided in several embodiments of this application will now be described. The automatic burr scraping device 100 includes a tool actuator 10 and a tool assembly 20.

[0026] The tool assembly 20 is installed in the tool actuator 10, which is installed in the fully automatic burr removal machine. The actuator of the fully automatic burr removal machine drives the tool actuator 10 and the tool assembly 20 to move towards one end of the workpiece, so that the tool assembly contacts the burr / deburr position of the workpiece. Then, the tool actuator drives the tool assembly 20 to move along the position of the workpiece where the burr / deburr needs to be removed, thereby removing the burr / deburr from the workpiece. The tool actuator 10 has a tool floating mounting structure 30, which includes a first floating limit seat 31, a first guide rod 32 disposed on the first floating limit seat 31, a first floating seat 33 movably disposed on the first guide rod 32, and a first elastic member 34 elastically abutting between the first floating limit seat 31 and the first floating seat 33. The tool assembly 20 is fixedly installed on the first floating seat 33.

[0027] Specifically, compared with the prior art, in the first aspect, the first floating seat 33 is movably arranged on the first guide rod 32, and the first elastic member 34 is arranged between the first floating limit seat 31 and the first floating seat 33, so as to form a floating tool mounting structure; when the tool assembly 20 performs deburring on a workpiece, the first elastic member 34 is compressed at a thicker position of the workpiece and rebounds at a thinner position of the workpiece, maintaining a constant pressure applied to the tool assembly 20, thereby eliminating the problems of over-cutting or insufficient scraping of the workpiece by the tool assembly 20, and further improving the reliability and production yield of the deburring operation. In the second aspect, the use of the floating tool mounting structure can buffer the impact force between the tool assembly 20 and the workpiece, reduce vibration and wear, alleviate the edge fatigue of the tool assembly 20, prolong the service life of the scraping blade 22 by 30% to 50%, and at the same time reduce the looseness or damage of equipment components caused by vibration; in the third aspect, the movement stroke range of the first floating seat 33 can be adjusted by replacing the first elastic member 34 with different elastic forces, so as to adapt to workpieces of different thicknesses; the replacement of the first elastic member 34 is simple, which can effectively reduce the time required for commissioning.

[0028] First Embodiment Please also refer to Figures 1 to 2 , which is a specific structure of the automatic deburring apparatus 100 provided in the first embodiment.

[0029] In the first embodiment, the first floating limit seat 31 is configured in a "匚"-shaped structure and encloses a first limit notch 311. One end of the first floating limit seat 31 is provided with a first mounting through hole 312, and the other end is provided with a second mounting through hole 313; one end of the first guide rod 32 is inserted into the first mounting through hole 312, the other end is inserted into the second mounting through hole 313, and the first floating seat 33 is mounted on the first guide rod 32 in a vertically movable manner and located in the first limit notch 311.

[0030] Specifically, there are two first guide rods 32 spaced left and right, and the same number of first mounting through holes 312 and second mounting through holes 313 are configured according to the number of the first guide rods 32; the first mounting through hole 312 and the second mounting through hole 313 adapted to install one first guide rod 32 are coaxially arranged, and the first guide rod 32 is interference-fitted in the first mounting through hole 312 and the second mounting through hole 313. The first elastic member 34 is a spring, the first elastic member 34 is sleeved on the first guide rod 32, one end of the first elastic member abuts against the top of the first limit notch 311, and the other end abuts against the top of the first floating seat 33. The first floating seat 33 is provided with a first guide through hole 331, and the first guide rod 32 is inserted into the first guide through hole 331 so that the first floating seat 33 is mounted on the first guide rod 32 in a vertically movable manner and located in the first limit notch 311.

[0031] More specifically, the structure in which the first guide rod 32 supports the first floating seat 33 to move up and down, compared with the structure of guide rail and slider, can improve the smoothness of its sliding and reduce the jamming caused by burrs / flashes, thereby improving the reliability of the floating mounting structure 30 in floating control of the tool pressure of the tool assembly 20. At the same time, this floating mounting structure 30 does not require the cooperation of cylinders and sensors for control, which not only simplifies the overall structure, but also reduces the manufacturing cost of the equipment and facilitates later maintenance.

[0032] In the first embodiment, the tool assembly 20 includes a tool mounting plate 21 disposed on the first floating seat 33 and a scraper 22 disposed on the tool mounting plate 21; the scraper 22 can be driven to move vertically up and down by the actuator of the fully automatic burr machine. The scraper 22 is arranged to extend vertically, and the first guide rod 32 is installed to extend vertically up and down, so that the first floating seat 33 moves vertically up and down synchronously, and the scraper 22 can adjust the pressure on the workpiece by floating vertically up and down synchronously with the first floating seat 33.

[0033] It should be noted that in the first embodiment, the scraper 22 is pressed against the surface of the workpiece downwards to perform the deburring / de-burr removal operation, and the automatic deburring device 100 is a vertical automatic deburring device 100.

[0034] The tool actuator 10 is a rodless cylinder, which includes a first base 11 fixedly mounted on the fully automatic burring machine, a first crossbar 12 fixedly mounted on the first base 11, and a first cylinder body 13 movably mounted on the first crossbar 12. The first cylinder body 13 is provided with a first magnetic attraction component, and the first fixing plate 39 is provided with a second magnetic attraction component that attracts the first magnetic attraction component. The tool floating mounting structure 30 is mounted on the first fixing plate 39 and is detachably mounted to the bottom of the first cylinder body 13 via the first fixing plate 39.

[0035] Specifically, both the first magnetic attraction component and the second magnetic attraction component are magnets (not shown in the figure). They are magnetically attached to the first cylinder body 13 via the first fixing plate 39, which can play a pre-positioning function. Then, the first fixing plate 39 is screwed and fixed to the first rod body.

[0036] Second Embodiment Please refer to the following: Figures 3 to 5 The second embodiment provides the specific structure of the automatic burr scraping device 100. The structure of the automatic burr scraping device 100 provided in the second embodiment is roughly the same as that of the automatic burr scraping device 100 provided in the first embodiment, except that the tool floating mounting structure 30 is different.

[0037] In the second embodiment, the tool floating mounting structure 30 further includes a second floating limit seat 35, a second guide rod 36 disposed on the second floating limit seat 35, a second floating seat 37 movably disposed on the second guide rod 36, and a second elastic member 38 elastically abutting between the second floating limit seat 35 and the second floating seat 37; the first floating limit seat 31 is disposed on the second floating seat 37, and the second floating seat 37 is detachably mounted on the tool actuator 10 through the first fixing plate 39.

[0038] Specifically, the second elastic element 38 is a spring, which is sleeved on the second guide rod 36, with one end abutting against the top of the second limiting notch and the other end abutting against the top of the second floating limiting seat 35. Since the first floating limiting seat 31 and the second floating limiting seat 35 have the same structure, the second guide rod 36 and the first guide rod 32 have the same structure, the second floating seat 37 and the first floating seat 33 have the same structure, and the second elastic element 38 and the first elastic element 34 have the same structure, they will not be described in detail here.

[0039] In the second embodiment, the scraper 22 is defined to extend along the first axis b1, the first floating seat 33 moves along the second axis b2, and the second floating seat 37 moves along the third axis b3; the second axis b2 is inclined relative to the first axis b1 to form a first angle a1, and the third axis b3 is inclined relative to the first axis b1 to form a second angle a2, and the second axis b2 and the third axis b3 are inclined in different directions.

[0040] Specifically, the first axis b1 is vertically set to 0 degrees, the second axis b2 tilts upwards and to the right to form a first angle a1, which is 45 degrees; the third axis b3 tilts upwards and to the left to form a second angle a2, which is also 45 degrees. Therefore, the first floating seat 33 can move the scraper 22 upwards and to the right to compensate for the pressure of the workpiece on the scraper 22, and the second floating seat 37 can move the scraper 22 upwards and to the left to compensate for the pressure of the workpiece on the scraper 22. That is, the scraper 22 can be moved in both directions to compensate for the pressure of the workpiece on the scraper 22, thereby further improving the pressure adjustment effect and reliability of the tool floating mounting structure 30 on the scraper 22.

[0041] It should be noted that in the second embodiment, the scraper 22 is pressed against the surface of the workpiece downwards to perform the deburring / de-burr removal operation, and the automatic deburring device 100 is a vertical automatic deburring device 100.

[0042] Third Embodiment Please refer to the following: Figures 6 to 7The third embodiment provides the specific structure of the automatic burr scraping device 100. The structure of the automatic burr scraping device 100 provided in the third embodiment is roughly the same as that of the automatic burr scraping device 100 provided in the second embodiment. The difference is that it also includes a horizontal displacement actuator 40.

[0043] In the third embodiment, the horizontal displacement actuator 40 includes a first guide rail 41 mounted on the fully automatic blasting machine, a first slider 42 movably mounted on the first guide rail 41, a first displacement seat 43 fixedly mounted on the first slider 42, and a first cylinder 44 for driving the first displacement seat 43 to move horizontally. The tool actuator 10 is fixedly mounted on the first displacement seat 43.

[0044] Specifically, there are two first guide rails 41 with a front-to-back spacing, and both first guide rails 41 extend to the left and right. Each first guide rail 41 can be movably mounted with a first slider 42. The front and rear ends of the first displacement seat 43 are mounted with the two first sliders 42 respectively. There are two horizontal displacement actuators 40 with a left-to-right spacing, and the opposite sides of the two horizontal displacement actuators 40 are the working area 45. Each horizontal displacement actuator 40 is equipped with a tool actuator 10, and the scraper 22 of the tool actuator 10 is set towards the working area 45.

[0045] In the third embodiment, the scraper 22 extends horizontally left and right, defined as extending horizontally left and right along the first axis b1. The first floating seat 33 moves horizontally along the second axis b2, and the second floating seat 37 moves horizontally along the third axis b3. The second axis is inclined forward from left to right and forms a first angle with the first axis b1. The third axis is inclined backward from left to right and forms a second angle a2 with the first axis b1. The first angle a1 is 45 degrees, and the second angle is 45 degrees. Therefore, when the horizontal displacement actuator 40 drives the two tool actuators 10 to move relative to each other, so that the scraper 22 abuts against the workpiece surface, the tool actuators 10 can drive the scraper 22 to move horizontally back and forth to remove burrs / burrs from the workpiece surface.

[0046] It should be noted that in the third embodiment, the scraper 22 is pressed against the surface of the workpiece to the left or right to perform the deburring / de-burr removal operation. In this case, the automatic deburring device 100 is a horizontal automatic deburring device 100.

[0047] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
