Description

Technical Field

[0001] This utility model relates to the field of filter housing processing equipment, specifically to a side grinding device for processing filter housings. Background Technology

[0002] The filter housing is essentially a precision metal box, typically made of aluminum alloy, copper alloy, or stainless steel. It is the core physical structure of the filter. In short, the filter housing is not just an ordinary metal box, but the core physical carrier of a precision electromagnetic system. The primary goal of grinding its outer shell (especially the side walls and flange surfaces) is to eliminate machining defects, such as burrs and roughness, which negatively impact electromagnetic performance, ensuring signal processing accuracy and low loss. Secondly, it ensures sealing, improves assembly reliability, and enhances long-term product stability. Grinding is an indispensable precision manufacturing step in achieving high performance and high reliability for filters.

[0003] Existing grinding devices use top clamping, holding the filter from above while grinding from below. However, due to the varying and relatively small size of the filters, they are prone to detachment during grinding, easily causing workpiece deformation and affecting the grinding effect. Furthermore, the burrs and debris generated during grinding are scattered throughout the processing environment. Existing dust collection devices cannot effectively collect and protect against these burrs and debris, leading to accumulation of debris on the fixture positioning surface, causing workpiece clamping height deviation and affecting the efficiency of continuous grinding.

[0004] Therefore, it is necessary to invent a side grinding device for filter housing processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a side grinding device for filter housing processing, so as to solve the problem mentioned in the background art that the existing dust removal devices cannot effectively collect and protect against burrs and debris generated during the grinding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a side grinding device for processing filter housings, comprising a lower housing and an upper housing. A lead screw seat is fixedly connected to both sides of the inner cavity of the upper housing. A connecting plate is threadedly connected to both sides of the surface of the lead screw seat. A connecting rod is rotatably connected to the upper part of each connecting plate. A gear is fixedly connected to the top of each connecting rod. A slide rail is fixedly connected to the inner side of each connecting plate. A toothed rod is slidably connected to the inner side of each slide rail. A driving mechanism is hinged to one end of each toothed rod. A side frame is fixedly connected to one end of each connecting rod. A driving groove is formed in the middle of the side frame. A grinding mechanism is provided inside the driving groove. Buffer grooves arranged in a rectangular array are formed around the driving groove. A positioning mechanism is provided inside each buffer groove. A first collecting frame is fixedly connected to the inner side of each side frame. A second extension frame is slidably sleeved inside the first collecting frame.

[0007] Preferably, the driving mechanism includes two connecting rods, one end of each connecting rod is hinged to a movable plate, one side of the movable plate is fixedly connected to an electric cylinder, and one side of the upper housing is fixedly connected to a buffer sleeve, with the inner side of the buffer sleeve slidably sleeved with the outer side wall of the electric cylinder.

[0008] Preferably, the polishing mechanism includes two driven rollers, a tension roller is rotatably connected to the middle of the inner cavity of the drive groove, abrasive cloth is rotatably sleeved on the surfaces of both driven rollers and the tension roller, and a motor is fixedly connected to the top of the drive groove.

[0009] Preferably, the positioning mechanism includes a reset rod, with buffer rods slidably sleeved on both sides of the reset rod, and an abutment plate hinged to the other end of the buffer rod.

[0010] Preferably, a rotating seat is fixedly connected to the bottom of the inner cavity of the lower housing, a second electric cylinder is fixedly connected to the top of the rotating seat, and a first locking plate is fixedly connected to the top of the second electric cylinder.

[0011] Preferably, a bracket is fixedly connected to one side of the inner cavity of the lower housing, a third electric cylinder is fixedly connected to the top of the bracket, and a second locking plate is fixedly connected to the telescopic end of the third electric cylinder through the bracket.

[0012] Preferably, a collection plate is provided on both sides of the inner cavity of the side frame, and a collection groove is connected to the outer side of each collection plate.

[0013] Preferably, the bottom of each of the second extension frames is provided with a semi-circular perforation.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The electric cylinder in the drive mechanism pulls the moving plate backward. The moving plate, through the connecting rods on both sides, pulls the rack connected to it backward. The gear meshing with the rack rotates in opposite directions and synchronously drives the connecting rod at the bottom to rotate outward, thereby causing the two side frames to unfold outward from their closed position. The space between the two side frames is used to place the filter housing. Then, the electric cylinder pulls the moving plate in the opposite direction, causing the side frames to rotate towards each other until they close. Depending on the size of the housing to be polished, the motor on one side of the lead screw seat is turned on, causing the lead screw to rotate and drive the connecting plate, slide rail, and rack on its surface to move towards each other. This, in turn, causes the connecting rod to drive the side frames to move synchronously. During this process, the connecting rods on both sides will push the moving plate in opposite directions. Along with the electric cylinder, the buffer sleeve assists the electric cylinder in counteracting the backward thrust. The first collecting frame and the second extension frame are slidably connected by a spring, so that when the second extension frame is subjected to external pressure, it will contract towards the inside of the first collecting frame, ensuring that the shell is always closed around the sides and bottom during the grinding process. This ensures that the burrs and waste generated during the process cannot escape from the collecting frame. Before use, an external exhaust fan is connected to the outside of the collection tank, which can extract the burrs and debris through the collecting plate to avoid accumulation in the collecting frame. This effectively improves the efficiency of the device in collecting burrs and debris generated during the process, and avoids the generation and spread of flying debris, which may affect processing safety and accuracy.

[0016] 2. The filter housing is vertically clamped and fixed by the first and second locking plates, ensuring that the housing will not shift to either side during processing. This also avoids the need for repeated rotation and fixing of the housing during grinding, which would otherwise require parallel fixing of the housing's sides. The distance between the external first collection frame and the side frame is controlled by a lead screw, ensuring that the contact plate at the positioning mechanism contacts the outer wall of the housing. Continuous rotation of the lead screw advances the housing until the abrasive cloth in the grinding mechanism adheres tightly to the outer side of the housing. The motor, acting as the drive source, transmits rotational power to the abrasive cloth via a tension roller, continuously grinding the outer wall of the housing. The second electric cylinder is set to push... The process involves the second electric cylinder vertically pushing the housing upwards, causing continuous grinding of the outer wall of the housing from top to bottom. After grinding is completed, the lead screw reverses, leaving sufficient space in the grinding mechanisms on both sides. This allows the rotating seat to rotate the upper housing, rotating the un-grinded side wall of the housing towards the grinding mechanism. The above operation is repeated, and the outer wall of the housing is continuously ground with abrasive cloth. This setup allows for adaptive grinding of housings of different specifications. The housing is first positioned before grinding by the positioning mechanism, and then the third electric cylinder is controlled to push the second locking plate down to perform secondary positioning of the housing. This eliminates the need for manual precision clamping control of the housing before processing, improving the processing efficiency of continuous grinding. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5The device shown is a side grinding device for processing filter housings, including a lower housing 1 and an upper housing 2. A lead screw seat 3 is fixedly connected to both sides of the inner cavity of the upper housing 2. A connecting plate 4 is threaded to both sides of the surface of the lead screw seat 3. A connecting rod 5 is rotatably connected to the upper part of each connecting plate 4. A gear 6 is fixedly connected to the top of each connecting rod 5. A slide rail 7 is fixedly connected to the inner side of each connecting plate 4. A toothed rod 8 is slidably connected to the inner side of each slide rail 7. A driving mechanism 9 is hinged to one end of the toothed rod 8. A side frame 10 is fixedly connected to one end of each connecting rod 5. A driving groove 11 is formed in the middle of the side frame 10. A grinding mechanism 12 is provided inside the driving groove 11. Buffer grooves 13 arranged in a rectangular array are formed around the driving groove 11. A positioning mechanism 14 is provided inside each buffer groove 13. A first collecting frame 15 is fixedly connected to the inner side of each side frame 10. A second extension frame 16 is slidably sleeved inside the first collecting frame 15.

[0027] The drive mechanism 9 includes two connecting rods 91, one end of each connecting rod 91 is hinged to a movable plate 92, one side of the movable plate 92 is fixedly connected to an electric cylinder 93, one side of the upper housing 2 is fixedly connected to a buffer sleeve 94, and the inner side of the buffer sleeve 94 is slidably sleeved with the outer side wall of the electric cylinder 93.

[0028] Specifically, in use, the electric cylinder 93 is used as the driving source, and the buffer sleeve 94 fixes the electric cylinder 93 and counteracts the reverse thrust. By controlling the electric cylinder 93 to push and pull the moving plate 92, the moving plate 92 drives the rack 8 to move horizontally through the connecting rods 91 on both sides.

[0029] The grinding mechanism 12 includes two driven rollers 121, a tension roller 122 is rotatably connected to the middle of the inner cavity of the drive groove 11, and abrasive cloth 123 is rotatably sleeved on the surfaces of the two driven rollers 121 and the tension roller 122. A motor 124 is fixedly connected to the top of the drive groove 11.

[0030] Specifically, during use, the surfaces of both the driven roller 121 and the tension roller 122 are provided with abrasive cloth 123. The motor 124 serves as a rotational power source, transmitting rotational power to the tension roller 122, causing the tension roller 122 to drive the abrasive cloth 123 to rotate synchronously with the driven wheels on both sides. The high-speed rotation of the abrasive cloth 123 is used to polish and deburr the perimeter of the housing.

[0031] The positioning mechanism 14 includes a reset rod 141, with buffer rods 142 slidably sleeved on both sides of the reset rod 141, and an abutment plate 143 hinged to the other end of the buffer rod 142.

[0032] Specifically, during use, when the contact plate 143 contacts the outer wall of the housing, the resulting reverse pressure will push the buffer rod 142 to unfold to both sides. The springs on both sides of the surface of the reset rod 141 will give the buffer rod 142 a reverse thrust and assist the contact plate 143 in resetting.

[0033] A rotating seat 17 is fixedly connected to the bottom of the inner cavity of the lower housing 1, a second electric cylinder 18 is fixedly connected to the top of the rotating seat 17, and a first locking plate 19 is fixedly connected to the top of the second electric cylinder 18.

[0034] Specifically, in use, the second electric cylinder 18 pushes and pulls the upper first locking plate 19, causing the first locking plate 19 to move vertically in space, thereby controlling the vertical height of the housing. After the grinding process on one side is completed, the rotating seat 17 drives the second electric cylinder 18 to rotate, causing the upper housing to rotate so that the grinding area faces the grinding assembly to complete the grinding.

[0035] A bracket 20 is fixedly connected to one side of the inner cavity of the lower housing 1. A third electric cylinder 21 is fixedly connected to the top of the bracket 20. The telescopic end of the third electric cylinder 21 passes through the bracket 20 and is fixedly connected to a second locking plate 22.

[0036] Specifically, during use, the bracket 20 mainly supports and fixes the third electric cylinder 21. The third electric cylinder 21 pushes the second telescopic plate downward vertically after it is positioned on one side of the positioning mechanism 14 through its telescopic end, and presses down the housing to form a secondary positioning and fixation.

[0037] Collection plates 23 are provided on both sides of the inner cavity of the side frame 10, and collection grooves 24 are connected to the outer sides of the collection plates 23.

[0038] Specifically, during use, the collection tank 24 can be connected to an external fan before the device is in operation. By creating negative pressure at the collection plates 23 on both sides, the burrs and debris between the side frames 10 are sucked into the collection tank 24 and discharged uniformly.

[0039] The bottom of each of the second extension frames 16 has a semi-circular perforation.

[0040] Specifically, in use, the semi-circular through holes at the bottom of the second extension frames 16 on both sides can be connected together to form an annular through groove, which allows the telescopic end of the second electric cylinder 18 at the bottom to pass through the second extension frame 16 and connect with the first locking plate 19, and push the first locking plate 19 to move vertically.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
