Description

Technical Field

[0001] The invention relates to the technical field of waveguide tube processing, in particular to a waveguide tube rectangular inner hole planing tool and waveguide tube rectangular inner hole planing processing equipment. Background Art

[0002] A waveguide is a hollow, smooth metal conduit. It is an essential component for electromagnetic wave transmission in the information and communications field. The smooth interior of a waveguide is required to minimize electromagnetic wave transmission losses.

[0003] Existing waveguides are usually copper alloy waveguides and aluminum alloy waveguides, which are usually processed by die forming, extrusion, machining, wire cutting and other methods.

[0004] Magnesium-lithium alloy is one-third lighter than aluminum alloy and has better electromagnetic shielding properties than copper alloy and aluminum alloy. Using magnesium-lithium alloy to prepare waveguide tubes can produce a waveguide tube with light weight and excellent electromagnetic shielding properties. However, due to the relatively soft texture of magnesium-lithium alloy, the waveguide tube blank obtained by extrusion molding will have vertical lines or marks, which can easily cause the smoothness, flatness and straightness of the inner hole surface of the waveguide tube to fail to meet the standards, resulting in a low yield. Summary of the Invention

[0006] The technical solution adopted by the present invention to solve its technical problem is: a waveguide rectangular inner hole planing tool, including a knife bar, a planer, a push rod, a spring and a spring stopper, the knife bar has an inner hole, and the front part of the knife bar has two knife grooves symmetrically arranged in an upper and lower direction, the rear side of the knife groove has a first inclined surface inclined backward from the outside to the inside relative to the knife bar, the push rod is slidably inserted into the inner hole of the knife bar, the front end of the push rod has a second inclined surface symmetrically arranged in an upper and lower direction, the second inclined surface is inclined forward from the outside to the inside relative to the push rod, the bottom of the planer has a third inclined surface that cooperates with the second inclined surface of the push rod, and is used to prevent the push rod from feeding forward. The planer is pushed outward, and the rear side surface of the planer has a fourth inclined surface that cooperates with the first inclined surface of the knife groove, which is used to push the planer forward when the planer is pushed out. A planer is installed in each knife groove, and the spring stop is slidably set in the inner hole of the knife rod and is located in front of the planer. The spring is installed in the inner hole of the knife rod and is located in front of the spring stop, which is used to apply a backward reset force to the planer. The front side of the planer and the rear side surface of the spring stop have mutually cooperating guide structures for vertically guiding the outward pushing and inward retraction actions of the planer. The left and right sides of the planer's cutting edge protrude from the side surfaces on both sides of the planer.

[0007] In some embodiments, optionally, the specific structure of the spring installed in the inner hole of the knife rod is: the spring is passed through the inner hole of the knife rod, the front end of the knife rod is closed, the rear end of the spring is pressed against the spring stop block, and the front end of the spring is pressed against the closed front end of the knife rod.

[0010] In some embodiments, optionally, the rear end of the tool rod has a connecting flange for connection to a tool feeding device.

[0011] A waveguide rectangular inner hole planing processing equipment includes a processing workbench, the above-mentioned waveguide rectangular inner hole planing tool, a tool feeding device and a waveguide fixture.

The head end of the feed rod is driven and cooperated with the push rod of the waveguide rectangular inner hole planing tool to drive the push rod to feed forward. The waveguide fixture is used to clamp the waveguide along the length direction of the waveguide rectangular inner hole planing tool. The tool feeding device is fixed on the processing workbench. The waveguide fixture can be reciprocated horizontally and vertically through a slide device. The tool feeding device is mounted on the processing workbench and driven by a reciprocating drive device, so that the waveguide rectangular inner hole planing tool can be inserted into the inner hole of the waveguide laterally and reciprocatingly, and the waveguide rectangular inner hole planing tool can be moved longitudinally along the inner hole surface of the waveguide rectangular inner hole; or the tool feeding device is mounted on the processing workbench and can be reciprocated laterally and longitudinally through a slide device and driven by a reciprocating drive device, and the waveguide fixture is fixed on the processing workbench, so that the waveguide rectangular inner hole planing tool can be inserted into the inner hole of the waveguide laterally and reciprocatingly, and the waveguide rectangular inner hole planing tool can be moved longitudinally along the inner hole surface of the waveguide rectangular inner hole.

Multi-layer planing can avoid excessive planing at one time, which will lead to excessive planing load and planing vibration marks, affecting the smoothness, flatness and straightness of the planed inner hole surface.

DETAILED DESCRIPTION

[0032] Example 1, as Figures 1 to 8 As shown, a waveguide rectangular inner hole planing tool includes a tool bar 1, a planer 2, a push rod 3, a spring 4 and a spring stopper 5.

[0033] like Figure 3 As shown, the tool rod 1 has an inner hole, and the front part of the tool rod 1 has two tool grooves 6 symmetrically arranged up and down, and the rear side of the tool groove 6 has a first inclined surface 6-1 inclined from outside to inside and backward relative to the tool rod 1.

[0034] like Figure 4 As shown, the push rod 3 is slidably inserted into the inner hole of the knife rod 1 , and the front end of the push rod 3 has a second inclined surface 3 - 1 symmetrically arranged up and down, and the second inclined surface 3 - 1 is inclined forward from the outside to the inside relative to the push rod 3 .

[0035] like Figure 6 and 7 As shown, the bottom of the planer 2 has a third inclined surface 2-1 that cooperates with the second inclined surface 3-1 of the propulsion rod 3, and is used to push the planer 2 outward when the propulsion rod 3 is fed forward. The rear side of the planer 2 has a fourth inclined surface 2-2 that cooperates with the first inclined surface 6-1 of the knife groove 6, and is used to push the planer 2 forward when the planer 2 is pushed out. A planer 2 is installed in each knife groove 6.

[0036] The spring stopper 5 is slidably arranged in the inner hole of the arbor 1 and is located in front of the planer 2. The spring 4 is installed in the inner hole of the arbor 1 and is located in front of the spring stopper 5, and is used to apply a backward reset force to the planer 2. The front side of the planer 2 and the rear side of the spring stopper 5 have mutually cooperating guide structures, which are used to vertically guide the outward pushing and inward retraction actions of the planer 2, and play a positioning role in the left and right positions of the planer installed in the knife groove 6.

[0037] like Figure 5 As shown, the specific structure of spring 4 installed in the inner hole of knife bar 1 is as follows: spring 4 is inserted into the inner hole of knife bar 1, the front end of knife bar 1 is closed, the rear end of spring 4 presses against spring stopper 5, and the front end of spring 4 presses against the closed front end of knife bar 1. The front end of knife bar 1 is closed by front end cover 7, which is fixed to the front end of knife bar 1 by fasteners such as bolts, and the front end of spring 4 presses against front end cover 7.

[0038] The guiding structure is specifically a guiding groove 8-1 and a guiding block 8-2, and the guiding groove 8-1 and the guiding block 8-2 are respectively located on the planer 2 and the spring stopper 5. The middle of the spring stopper 5 is provided with a clearance hole for the clearance propulsion rod 3.

[0039] like Figure 12 As shown, the left and right sides of the planer blade 2's cutting edge 2-3 protrude from the sides of the planer blade 2. The left and right sides of the planer blade are inclined inward from top to bottom, allowing the left and right sides of the cutting edge 2-3 to protrude from the sides of the planer blade 2. The cutting edge 2-3 of the planer blade 2 is perpendicular to the axis of the cutter bar 1. The planer blade 2 includes a cutter body 2-4 and a PCD blade 2-5 welded to the cutter body 2-4.

[0040] The rear end of the tool bar 1 has a connecting flange 9 for connecting to a tool feeding device 10 .

[0041] The V-mouth formed by the first bevel 6-1 and the second bevel 3-1 of the waveguide rectangular inner hole planing tool 12 has a self-positioning effect on the planer 2 embedded in the V-mouth, so that the planer 2 will not vibrate when subjected to planing resistance, but will always be tightly pressed in the V-mouth, ensuring that planing vibration marks are not easily generated during planing.

[0042] like Figures 9 to 13 As shown, a waveguide tube rectangular inner hole planing processing equipment includes a processing workbench 11, the above-mentioned waveguide tube rectangular inner hole planing tool 12, a tool feeding device 10 and a waveguide tube clamp 13. The rear end of the tool rod 1 of the waveguide tube rectangular inner hole planing tool 12 is installed on the tool feeding device 10. The tool feeding device 10 has a servo-driven feed rod 10-1. The head end of the feed rod 10-1 is driven and cooperated with the push rod 3 of the waveguide tube rectangular inner hole planing tool 12. Specifically, the head end of the feed rod 10-1 is pressed against the rear end of the push rod 3 to drive the push rod 3 to feed forward. The waveguide tube clamp 13 is used to clamp the waveguide tube 14 along the length direction of the waveguide tube rectangular inner hole planing tool 12.

[0043] like Figure 9As shown, the tool feeding device 10 is fixed on the processing workbench 11, and the waveguide fixture 13 is installed on the processing workbench 11 through a slide device so as to be reciprocatingly movable horizontally and vertically and is driven by a reciprocating drive device, so as to enable the waveguide rectangular inner hole planing tool 12 to be inserted horizontally and reciprocatingly into the inner hole of the waveguide tube 14, to plan the two opposite inner hole surfaces of the inner hole of the waveguide tube 14 at the same time, and to enable the waveguide rectangular inner hole planing tool 12 to move longitudinally along the inner hole surface of the rectangular inner hole of the waveguide tube.

[0044] The specific structure of the waveguide tube fixture 13 that can be installed on the processing workbench 11 for horizontal and vertical reciprocating movement through a sliding device is as follows: the sliding device specifically includes a horizontal slide 16 and a vertical slide 17. The horizontal slide 16 can be installed on the processing platform for horizontal reciprocating movement and is driven by a reciprocating drive device. The vertical slide 17 can be installed on the horizontal slide 16 for vertical reciprocating movement and is driven by a reciprocating drive device. The waveguide tube fixture 13 is installed on the vertical slide 17. The reciprocating drive devices that drive the horizontal slide 16 and the vertical slide 17 are both screw devices driven by servo motors.

[0045] The waveguide tube clamp specifically includes an upper clamping plate 18, a lower clamping plate 19 and a clamping bolt 15 connecting the upper clamping plate 18 and the lower clamping plate 19. The waveguide tube 14 is arranged between the upper clamping plate 18 and the lower clamping plate 19. Tightening the clamping bolt 15 can clamp the waveguide tube 14 between the upper clamping plate 18 and the lower clamping plate 19. The lower clamping plate 19 is installed on the longitudinal slide 17.

[0046] The tool feeding device 10 is specifically a linear electric servo cylinder, the exposed cylinder rod of the linear electric servo cylinder is the feed rod 10-1, the rear end of the tool rod 1 of the waveguide tube rectangular inner hole planing tool 12 has a connecting flange 9, and the waveguide tube rectangular inner hole planing tool 12 is installed on the front end of the cylinder body of the linear electric servo cylinder through the connecting flange 9 and the bolts passing through the connecting flange 9.

[0047] The process of planing the rectangular inner hole of the waveguide tube 14 using the waveguide tube rectangular inner hole planing tool 12 and the waveguide tube rectangular inner hole planing processing equipment of this embodiment 1 is as follows:

[0048] 1. First, install the waveguide rectangular inner hole planing tool 12 on the tool feeding device 10, and put the gauge on the waveguide rectangular inner hole planing tool 12 to calibrate the planer 2;

[0049] 2. Clamp the waveguide tube 14 to be processed by the waveguide tube fixture 13;

[0050] 3. The waveguide rectangular inner hole planing processing equipment is started to plan the two opposite inner hole surfaces of the inner hole of the waveguide 14 at the same time. The planing action process of the waveguide rectangular inner hole planing tool 12 is as follows:

[0051] 3.1、As Figures 10-12 As shown, first, the waveguide fixture 13 drives the waveguide 14 to move to the initial position through the slide device, and the tool feeding device 10 drives the feed rod 10-1 to push the planer 2 to the first set value. The waveguide fixture 13 drives the waveguide 14 to move toward the side of the waveguide rectangular inner hole planing tool 12 through the slide device, that is, to move horizontally backward, so that the waveguide rectangular inner hole planing tool 12 is inserted into the inner hole of the waveguide 14 from one side of the inner hole, such as the left side, and the two opposite inner hole surfaces of the inner hole of the waveguide 14 are planed simultaneously from the left side. When the planer 2 passes through the front end of the waveguide 14, one planing is completed, as shown in FIG. Figure 13 As shown;

[0052] 3.2. Retracting the waveguide rectangular inner hole planing tool 12: The feed device 10 drives the feed rod 10-1 to retract backward, and the spring 4 applies a backward restoring force to the planer 2 through the spring stopper 5, pushing the planer 2 to retract inward to prevent the planer 2 from touching the inner hole surface. Then, the waveguide fixture 13 drives the waveguide 14 to move forward laterally through the slide device, so that the waveguide rectangular inner hole planing tool 12 is pulled out of the inner hole of the waveguide 14, and the planer 2 passes through the rear end of the waveguide 14;

[0053] 3.3. The tool feed device 10 drives the feed rod 10-1 forward, pushing the planer 2 to a first set value. The waveguide fixture 13 drives the waveguide 14 to move longitudinally to the left via the slide device, causing the planer 2 to move longitudinally to the right relative to the inner hole. Then, the waveguide fixture 13 drives the waveguide 14 to move laterally backward via the slide device, inserting the waveguide rectangular inner hole planing tool 12 into the inner hole of the waveguide 14. When the planer 2 passes through the front end of the waveguide 14, the second planing is completed, and the second planing area overlaps with the first planing area.

[0054] 3.4. Repeat steps 3.2 and 3.3 until the planer 2 moves longitudinally to the rightmost side of the inner hole surface. After this planing, the inner hole surface is planed one layer from left to right.

[0055] 3.5. If the planing allowance is large, a second layer of planing can be performed, or even the nth layer of planing, where n is greater than 2. For the second layer of planing: first, retract the waveguide rectangular inner hole planing tool 12, and then repeat steps 3.1 to 3.4. However, each time planing is performed, the tool feeding device 10 drives the feed rod 10-1 to push the planer 2 to a second set value, which is greater than the first set value. The inner hole surface is planed from left to right for the second layer, and of course, the second layer can also be planed from right to left.

[0056] 3.6. Planing the nth layer: Repeat step 3.5 as many times as needed to plan the inner hole surface from left to right for the nth layer. After the multiple layers of planing are completed and the design size is reached, the waveguide rectangular inner hole planing tool 12 is retracted to complete the planing of the two opposite inner hole surfaces of the inner hole of the waveguide 14.

[0057] 4. Loosen the clamping bolt 15, unlock the waveguide tube 14 in the waveguide tube fixture 13, rotate the waveguide tube 14 90 degrees, and then clamp the waveguide tube 14 again through the waveguide tube fixture 13, and then repeat step 3 to complete the planing of the other two opposite inner hole surfaces of the inner hole of the waveguide tube 14. When the length and width difference of the rectangular inner hole of the waveguide tube 14 is too large, which is larger than the limited planing size range of the planer, that is, the planer is pushed to the limit position and still cannot plan the inner hole surface to the required size, it is necessary to replace the waveguide tube rectangular inner hole planing tool 12 with a larger size.

[0058] Example 2, a waveguide tube rectangular inner hole planing processing equipment is basically the same as Example 1, with the difference that: the tool feeding device 10 is installed on the processing workbench 11 through a slide device and can be reciprocated laterally and longitudinally and is driven by a reciprocating drive device, and the waveguide tube clamp 13 is fixed on the processing workbench 11, which is used to enable the waveguide tube rectangular inner hole planing tool 12 to be inserted laterally and reciprocatingly into the inner hole of the waveguide tube 14, to plan the two opposite inner hole surfaces of the inner hole of the waveguide tube 14 at the same time, and to enable the waveguide tube rectangular inner hole planing tool 12 to move longitudinally along the inner hole surface of the rectangular inner hole of the waveguide tube.

[0059] The process of planing the rectangular inner hole of the waveguide tube 14 using the waveguide tube rectangular inner hole planing tool 12 of Example 1 and the waveguide tube rectangular inner hole planing equipment of this Example 2 is basically the same as that of Example 1. The only difference is that the waveguide tube 14 of this Example 2 does not move, while the waveguide tube rectangular inner hole planing tool 12 moves relative to the waveguide tube 14 to complete the planing process.
