Description

Technical Field

[0001] This utility model relates to a jig, specifically a jig for processing the metal shell of a microwave frequency reducer, and belongs to the field of jig technology. Background Technology

[0002] As a key component in satellite communication and radar detection, microwave frequency reducers use metal housings that not only protect the internal precision electronic components but also serve important functions such as electromagnetic shielding, heat dissipation, and temperature conduction. Therefore, stringent requirements are placed on the surface precision and structural integrity of the housing. These metal housings are typically mass-produced using die casting. During die casting, molten metal fills the mold cavity under high pressure. After cooling and solidification, burrs and flash inevitably occur on the surface, edges, and internal joints of the housing. If these defects are not addressed promptly, they can affect the assembly precision of the housing with other components and may even cause short circuits in the internal circuitry or injure operators during subsequent use due to burr detachment. Therefore, polishing is essential to remove these defects. Currently, the industry commonly uses magnetic polishing machines to polish die-cast metal housings. The working principle involves using a magnetic field to drive magnetic steel needles in the polishing tank to rub against the workpiece surface at high speed, thereby achieving deburring, chamfering, and brightening effects.

[0003] However, in practice, a single polishing process requires processing multiple shells. Operators often pour multiple shells into the polishing tank in a disorderly manner, which leads to the shells easily stacking up. Some shells are completely covered, and their surfaces cannot make full contact with the magnetic steel needles, resulting in polishing dead corners and reducing the polishing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a machining fixture for the metal housing of a microwave frequency reducer in order to solve the above problems. This fixture can arrange multiple housings in an orderly manner inside the polishing tank, avoiding stacking between the housings and thus ensuring the polishing effect.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a machining fixture for the metal casing of a microwave frequency reducer, comprising a magnetic polishing machine. Two support legs are provided on both sides of the top of the magnetic polishing machine. The tops of the two support legs on the same side of the magnetic polishing machine are fixedly connected to the same drag rod. The drag rod has multiple positioning grooves, and a crossbar engages between two opposing positioning grooves. The crossbar has a hook structure, comprising a hook and a limiting protrusion. Multiple hooks are engaged on the crossbar, and a limiting protrusion is integrally formed on each hook. The limiting protrusion engages with the crossbar. A nut is threaded onto each hook, and the nut abuts against the crossbar. A fixing structure is provided on the support legs.

[0006] Preferably, the limiting protrusion has two cut surfaces, which are symmetrically distributed about the middle of the limiting protrusion.

[0007] Preferably, the multiple crossbars are linearly and equidistantly distributed, and the multiple hooks located on the same crossbar are linearly and equidistantly distributed.

[0008] Preferably, the top of the positioning groove cross-section is trapezoidal, and the cross-section at the end of the crossbar is trapezoidal.

[0009] Preferably, the cross-section of the support leg is L-shaped, and the two support legs located at both ends of the tow rod are symmetrically distributed about the middle of the tow rod.

[0010] Preferably, the fixing structure includes a screw and a clamping plate. The screw is rotatably connected to the support leg, and two clamping plates are threadedly connected to the screw. Two guide posts are fixedly connected to the clamping plates, and the guide posts are slidably connected to the support leg.

[0011] Preferably, a rotating rod is fixedly connected to the screw, and the rotating rod passes through the screw and is perpendicular to the screw.

[0012] Preferably, the two threads on the screw have opposite directions, the screw is located in the middle of the clamping plate, and the two guide posts on the same clamping plate are symmetrically distributed about the middle of the clamping plate.

[0013] The beneficial effects of this utility model are: during use, individual metal shells can be hooked onto the hooks. Since the multiple hooks on the same crossbar are linearly and equidistantly distributed, when all the hooks on one crossbar are hooked onto metal shells, the multiple metal shells can be arranged in an orderly and equidistant manner. Once all the hooks on one crossbar are hooked onto metal shells, the two ends of the crossbar can be engaged with the two corresponding positioning slots, thereby achieving precise positioning of the crossbar. This process is repeated until all the hooks on all the crossbars are hooked onto metal shells, and then the multiple crossbars are successively engaged with the two drag bars. At this point, multiple metal shells... The metal shells are arranged in an orderly manner inside the polishing tank, with a certain distance between adjacent metal shells. This ensures that each metal shell is fully polished during the polishing process, avoiding stacking and creating polishing dead corners, thus effectively guaranteeing the polishing effect. When a hook is damaged, the nut can be unscrewed, and the hook can be removed and replaced. Therefore, when a single hook is damaged, only the damaged hook needs to be replaced, rather than replacing the entire hook, thus saving on usage costs. The limiting protrusions can position the hook during installation, ensuring that the position of the hook remains unchanged after replacement. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 As shown, a machining fixture for the metal casing of a microwave frequency reducer includes a magnetic polishing machine 7. Two support legs 1 are provided on both sides of the top of the magnetic polishing machine 7. A common drag rod 2 is fixedly connected to the top of the two support legs 1 located on the same side of the magnetic polishing machine 7. The drag rod 2 has multiple positioning grooves 3. A common crossbar 4 engages between two opposing positioning grooves 3. The crossbar 4 has a hook structure 5, which includes a hook 501 and a limiting protrusion 502. Multiple hooks 501 are engaged on the crossbar 4. A limiting protrusion 502 is integrally formed on each hook 501, engaging with the crossbar 4. A nut 504 is threaded onto each hook 501, abutting against the crossbar 4. A fixing structure 6 is provided on each support leg 1.

[0021] As a technical optimization of this utility model, the limiting protrusion 502 is provided with two cut surfaces 503. The cut surfaces 503 are in close contact with the crossbar 4 to ensure that the orientation of the hook 501 will not change after installation. The two cut surfaces 503 are symmetrically distributed about the middle of the limiting protrusion 502.

[0022] As a technical optimization of this utility model, the multiple crossbars 4 are linearly and equidistantly distributed, and the multiple hooks 501 located on the same crossbar 4 are linearly and equidistantly distributed. Therefore, multiple metal shells can be arranged in an orderly manner inside the polishing groove, avoiding stacking and thus ensuring the polishing effect.

[0023] As a technical optimization of this utility model, the top of the cross section of the positioning groove 3 is trapezoidal, and the cross section of the end of the crossbar 4 is trapezoidal, so it can play a role in motion guidance when the end of the crossbar 4 is engaged with the positioning groove 3.

[0024] As a technical optimization of this utility model, the cross-section of the support leg 1 is L-shaped, and the two support legs 1 located at both ends of the tow rod 2 are symmetrically distributed about the middle of the tow rod 2, so that the two support legs 1 can form a stable support for the tow rod 2.

[0025] As a technical optimization of this utility model, the fixing structure 6 includes a screw 601 and a clamping plate 602. The screw 601 is rotatably connected to the support leg 1. The two threads on the screw 601 have opposite directions, so when the screw 601 rotates in one direction, the two clamping plates 602 can move in opposite directions. The screw 601 is located in the middle of the clamping plate 602. Two clamping plates 602 are threadedly connected to the screw 601. Two guide posts 603 are fixedly connected to the clamping plate 602. The two guide posts 603 located on the same clamping plate 602 are symmetrically distributed about the middle of the clamping plate 602. The two guide posts 603 can guide the movement of the clamping plate 602. The guide posts 603 are slidably connected to the support leg 1.

[0026] As a technical optimization of this utility model, a rotating rod 604 is fixedly connected to the screw 601. The rotating rod 604 passes through the screw 601 and is perpendicular to the screw 601, so the screw 601 can be easily rotated by holding the rotating rod 604.

[0027] In use, this invention allows the two support legs 1 to be positioned at the top of the magnetic polishing machine 7. The screw 601 is rotated via the rotating rod 604, causing the screw 601 to drive the two clamping plates 602 to move relative to each other. Two guide posts 603 guide the movement of the clamping plates 602. When both clamping plates 602 are simultaneously clamped between the magnetic polishing machine 7, the rotating rod 604 is stopped, thus fixing one support leg 1. This process is repeated to fix the other support leg 1. Once both support legs 1 are fixed, the drag bar 2 is secured. During use, individual metal shells can be hooked onto the hooks 501. Since the hooks 501 on the same crossbar 4 are linearly and equidistantly distributed, when multiple hooks 501 on one crossbar 4 are all hooked with metal shells, the multiple metal shells can be arranged in an orderly and equidistant manner. Once all hooks 501 on one crossbar 4 are hooked with metal shells, the two ends of the crossbar 4 can be separated. The crossbar 4 is precisely positioned by engaging with the two corresponding positioning slots 3. The above operation is then repeated so that all the crossbar 4 hooks 501 are hung with metal shells. The crossbars 4 are then engaged with the two drag bars 2 one after another. At this time, the multiple metal shells will be arranged in an orderly manner inside the polishing groove, and there is a certain distance between the adjacent metal shells. Therefore, during the polishing process, each metal shell can be fully polished, avoiding stacking and polishing dead corners, thus effectively ensuring the polishing effect. When the hook is damaged, the nut 504 can be unscrewed, and then the hook 501 can be removed and replaced. Therefore, when a certain hook 501 is damaged, only the individual hook needs to be replaced, instead of replacing the whole hook, thus saving the cost of use. The limiting protrusion 502 and the two cut surfaces 503 can be used to position the hook 501 during installation, thus ensuring that the position of the hook 501 remains unchanged after replacement.
