[0031] Combine the following Figure 1-Figure 3 The invention describes a flange-sealed heating plate processing device.

[0032] like Figure 1 As shown, in one embodiment, a flange-sealed heating plate processing device includes a support plate 100 , a press 200 , a clamping drive 300 and an alignment fixture 400 .

[0033] The support plate 100 has a limiting portion 101 for supporting the heating plate. The bottom of the support plate 100 has a T-slot that matches the milling machine worktable. The support plate 100 is installed on the milling machine worktable through the T-slot, and the position of the support plate 100 on the milling machine worktable is fixed by using bolts. The limiting portion 101 is an L-shaped protrusion on the top of the support plate 100. The lateral displacement of the heating plate is fixed by pressing the heating plate to the inner corner of the limiting portion 101.

[0034] The press 200 is located above the support plate 100 and is used to press the heating plate onto the support plate 100 . The press 200 is pressed onto the top of the heating plate and combined with the support plate 100 to achieve an upper and lower clamping and limiting effect on the heating plate.

[0035] The clamping drive member 300 is installed on the support plate 100 and is transmission-connected to the press 200, and is used to drive the press 200 to move up and down relative to the support plate 100. The bottom of the clamping drive member 300 is connected to the bearing of the support plate 100, and then drives the press 200 to move up and down by rotation.

[0036] The alignment fixture 400 is installed on the press 200 and has an alignment portion 401 for fixing the flange at a position that coincides with the axis of the through hole of the heating plate. The alignment portion 401 is fixed in advance just above the through hole of the heating plate, so that the flange can be fixed at a position that coincides with the axis of the through hole of the heating plate with reference to the alignment portion 401.

[0037] The inner surface of the limiting portion 101 is in contact with the right-angled edge of the heating plate to limit the position of the heating plate on the support plate 100 , and the alignment portion 401 is located at one end of the alignment fixture 400 away from the pressing tool 200 .

[0038] Specifically, before drilling holes in the heating plate and the flange, first fix the support plate 100 carrying the press 200, the clamping drive 300 and the alignment clamp 400 to the workbench of the milling machine, and then place the heating plate on the support plate 100 and press it against the inner corner of the limiting portion 101. At this time, the clamping drive 300 is rotated to drive the press 200 to move down and press on the top of the heating plate, so as to achieve the upper and lower clamping and limiting of the heating plate, and the lateral displacement of the heating plate is limited in combination with the limiting portion 101;

[0039] The position of the alignment fixture 400 on the press 200 is adjusted according to the through hole of the heating plate, so that the alignment portion 401 is located directly above the through hole of the heating plate, and the flange is clamped on the alignment fixture 400 with reference to the alignment portion 401 so that the axis of the flange and the heating plate coincide with each other, so as to simulate the relative position of the flange and the heating plate in the horizontal direction when connected;

[0040] According to the punching position and hole size, adjust the position of the milling machine tool, set the milling machine speed, feed speed and cutting depth, so that the milling machine tool can continue to move downward to punch holes in the heating plate after passing through the flange, thereby improving the accuracy of the alignment of the flange and the screw holes on the heating plate.

[0041] The flange-sealed heating plate processing device of this embodiment clamps and fixes the heating plate in the height direction by arranging a support plate 100 and a press 200, limits the heating plate in the horizontal direction in combination with a limiting portion 101, and arranges a displaceable alignment fixture 400 on the press 200 to fix the flange, and arranges an alignment portion 401 as a reference. By moving the alignment portion 401 to just above the through hole of the heating plate in advance, the flange is aligned and fixed just above the through hole of the heating plate with reference to the alignment portion 401, so as to simulate the relative position of the flange and the heating plate in the horizontal direction when connected. Combined with the setting of the milling machine parameters, the flange and the heating plate connection screw holes can be punched and formed at one time, which effectively improves the alignment accuracy of the screw holes processed by the flange and the heating plate.

[0042] like Figure 2 As shown, in one embodiment, the press 200 includes a first press plate 210 and a second press plate 220, and the first press plate 210 is fixedly connected to the second press plate 220. The first press plate 210 is arranged along the longer side of the limiting portion 101, and the second press plate 220 is arranged along the shorter side of the limiting portion 101. When the heating plate is clamped up and down, the first press plate 210 and the second press plate 220 are pressed together on a group of right-angled sides of the heating plate, thereby pressing down the three groups of ends of the heating plate to improve the stability of clamping the heating plate.

[0043] In this embodiment, the clamping drive member 300 includes a driving screw 310 and an auxiliary member 320. The bottom of the driving screw 310 is rotatably mounted on the support plate 100 through a bearing, and its thread is installed at the intersection of the first pressure plate 210 and the second pressure plate 220. The auxiliary member 320 is installed at one end of the support plate 100 away from the driving screw 310, and is used to support the first pressure plate 210 or the second pressure plate 220 in an idle state.

[0044] In order to facilitate the rotation of the driving screw 310 , a screw handle is installed at the top end of the driving screw 310 .

[0045] Specifically, when the processed heating plate is removed from the support plate 100, the screw handle is rotated in a specified direction, and the screw handle drives the driving screw 310 to rotate. The driving screw 310 drives the first pressing plate 210 and the second pressing plate 220 to move up to a suitable height to provide space for the heating plate to be moved out.

[0046] Since only one end of the first pressure plate 210 and the second pressure plate 220 is supported after being lifted, and the outer ends of the first pressure plate 210 and the second pressure plate 220 are suspended in the air, the driving screw 310 bears the gravity of the first pressure plate 210 and the second pressure plate 220, and is also subjected to the pulling force of the outer ends of the first pressure plate 210 and the second pressure plate 220, which can easily cause the driving screw 310 to deform. To solve this problem, the auxiliary component 320 includes a support screw 322 and a support ring 324. The support screw 322 is fixedly mounted on the support plate 100, and the support ring 324 is threadedly mounted on the support screw 322. The surface of the first pressure plate 210 or the second pressure plate 220 corresponding to the support screw 322 has a movable through hole 201, and the inner diameter of the movable through hole 201 is between the outer diameter of the support screw 322 and the outer diameter of the support ring 324.

[0047] Specifically, after the first pressing plate 210 and the second pressing plate 220 are moved upward, the support ring 324 is rotated to move it upward along the support screw 322 until it is in contact with the bottom of the first pressing plate 210 or the second pressing plate 220, thereby supporting the first pressing plate 210 or the second pressing plate 220.

[0048] like Figure 3 As shown, in one embodiment, the alignment fixture 400 includes an adjusting arm 410, a telescopic arm 420 and a chuck 430. The adjusting arm 410 is displaceably mounted on the first pressure plate 210 and extends toward the inner surface of the limiting portion 101. The telescopic arm 420 is displaceably mounted on the adjusting arm 410. The adjusting arm 410 can move along the length direction of the first pressure plate 210, and the movable arm 420 can move along the length direction of the adjusting arm 410 to achieve adjustment of the lateral and longitudinal positions of the chuck 430.

[0049] In this embodiment, the chuck 430 is fixedly mounted on the telescopic arm 420, and its bottom is flush with the bottom of the first pressure plate 210. By setting the bottom of the chuck 430 to be flush with the first pressure plate 210, the chuck 430 can be supported by the heating plate when punching the flange, preventing the chuck 430 from being deformed by excessive downward pressure and affecting the punching accuracy.

[0050] In this embodiment, the telescopic arm 420 has a secondary bayonet 421 and a secondary locking member 422 . The secondary locking member 422 extends to the secondary bayonet 421 by passing through the adjustment arm 410 , so as to fix the overall length of the adjustment arm 410 and the telescopic arm 420 .

[0051] Specifically, when adjusting the position of the chuck 430 along the length direction of the second pressure plate 220, the secondary locking piece 422 is removed from the secondary snap-in 421 and the adjusting arm 410, and the telescopic arm 420 is moved along the length direction of the adjusting arm 410 so that the alignment portion 401 is located on the axial plane parallel to the through hole of the heating plate and the first pressure plate 210, and then the secondary locking piece 422 is passed through the adjusting arm 410 and inserted into the secondary snap-in 421, thereby fixing the relative position of the movable arm 420 and the adjusting arm 410.

[0052] Optionally, the surface of the adjusting arm 410 relative to the secondary bayonet 421 has multiple groups of secondary locking screw holes, and the secondary locking member is a secondary locking bolt, which is threaded through the secondary locking screw hole and inserted into the secondary bayonet 421 to fix the relative position of the telescopic arm 420 and the adjusting arm 410.

[0053] In this embodiment, the adjusting arm 410 has a main bayonet 411 and a main locking member 412, and the first pressure plate 210 has an adjusting slot 211. The end of the adjusting arm 410 that is away from the chuck 430 is slidably installed in the adjusting slot 211. The main locking member 412 extends through the outer wall of the adjusting slot 211 to the main bayonet 411 to lock the position of the adjusting arm 410 on the first pressure plate 210.

[0054] Specifically, when adjusting the position of the chuck 430 along the length direction of the first pressure plate 210, the main locking piece 412 is moved out from the main clamping hole 411 and the outer wall of the adjustment slot 211, and the adjustment arm 410 is moved along the adjustment slot 211 to the position where its center line intersects with the axis of the through hole of the heating plate, and the main locking piece 412 is inserted into the main clamping hole 411 through the outer wall of the adjustment slot 211, thereby fixing the position of the adjustment arm 410.

[0055] Optionally, the surface of the adjustment slot 211 relative to the main bayonet 411 has a main locking screw hole, and the main locking member is a main locking bolt, which is threaded through the main locking screw hole and tightly installed in the main bayonet 411 to fix the relative position of the adjustment arm 410 and the first pressure plate 210.

[0056] In this embodiment, the chuck 430 includes a bracket 432, a clamping block 434 and a fastener 436. The bracket 432 is fixedly mounted on the end of the telescopic arm 420 away from the adjusting arm 410. The clamping block 434 can be horizontally displaced on the bracket 432. The fastener 436 is rotatably mounted on the clamping block 434 through a bearing, and is used to drive the clamping block 434 to press against and fix the flange.

[0057] Preferably, the bracket 432 is "Y"-shaped, and its end away from the telescopic arm 420 has a limit block, and the fastener 436 includes a front fastening screw and a rear fastening screw, one end of the front fastening screw away from the clamping block is threadedly installed on the telescopic arm, and the end of the rear fastening screw away from the clamping block is threadedly installed on the limit block.

[0058] Specifically, when locking and clamping the flange on the bracket 432, the front fastening screw and the rear fastening screw are rotated respectively to drive the clamping block 434 to move toward the flange and press against the outer surface of the flange, thereby fixing the horizontal displacement of the flange to facilitate drilling processing.

[0059] In this embodiment, the alignment portion 401 is located on the bracket 432 and is a groove located on a concentric circle.

[0060] Specifically, when fixing the position of the bracket 432, refer to the alignment portion 401 thereon to fix the bracket 432 just above the through hole of the heating plate;

[0061] When the flange is fixed to the bracket 432, the flange is aligned and clamped to a position that coincides with the axis of the through hole of the heating plate with reference to the alignment portion 401.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
