Description

Technical Field

[0001] This invention relates to the field of mold processing technology, and more specifically, to a drilling mold for intermediate plates and a processing platform for its application. Background Technology

[0002] With the continued growth in demand in the air conditioning market, the machining precision and efficiency of the intermediate plate, a core component of the compressor, have become crucial. This component is responsible for equipment installation, gas compression, and sealing, and requires multiple precision machining processes such as drilling, chamfering, side holes, and beveled holes to ensure accurate fit with other components.

[0003] Currently, the processing steps of this intermediate plate need to be carried out in stages on multiple machines: drilling is done by a drilling machine, chamfering is done by a chamfering machine, and side holes and angled holes need to be processed on a milling machine or machining center with the help of special tooling.

[0004] The above discrete processing mode leads to multiple clamping and equipment switching of intermediate plates, which not only prolongs the processing cycle and reduces efficiency, but also easily causes deviations in hole diameter and hole position due to the cumulative error of multiple equipment. At the same time, the separation of manual sampling and processing is not only labor-intensive, but also makes it difficult to monitor and trace quality problems in a timely manner, which seriously restricts the production efficiency and quality stability of the compressor's core components.

[0005] Therefore, this application proposes a drilling mold for intermediate plates and a processing platform for its application to solve the above problems. Summary of the Invention

[0006] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of this invention is to provide a drilling mold for intermediate plates and a processing platform for its application, which solves the problems of multiple clamping, process dispersion error and quality inspection lag caused by discrete processing of intermediate plates, which affect the production efficiency and quality stability of the core components of the compressor.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a drilling mold for intermediate plates, comprising: an assembly platform; a worktable installed on the top of the assembly platform; a drive box installed on one side of the top of the worktable, and a support plate installed on the other side of the top; a first loading plate fixedly installed at the output end of the drive box; a second loading plate rotatably installed at the inward end of the support plate; a flat platform installed between the first loading plate and the second loading plate; two rows of rotary clamping cylinders, arranged equidistantly at the front and rear of the top of the flat platform; clamping plates installed on the telescopic ends of the rotary clamping cylinders, the clamping plates including unidirectional short plates and bidirectional long plates; a placement plate installed on the top surface of the flat platform, located between two adjacent rotary clamping cylinders, and a circular intermediate plate placed on the placement plate; a limit post vertically installed in the middle of the placement plate.

[0008] In a new embodiment, the limiting posts are rotatably mounted on the flat platform. An expansion assembly for locking the inner ring of the intermediate plate of the circular ring is installed on the top of the limiting posts. An exhaust assembly is provided in the placement tray. A drive assembly is installed on the bottom surface of the flat platform to drive the limiting posts and the placement tray fixed thereto to rotate synchronously. A gas supply assembly is installed at the bottom of the flat platform to supply gas into the limiting posts.

[0009] In a new embodiment, the expansion assembly includes: a positioning post, fixedly installed on the top of a limiting post; an inner sleeve post, coaxially fixedly installed in the middle of the positioning post, with its internal cavity communicating with the inner cavity of the limiting post; a pushing cone block sliding inside the inner sleeve post, a sliding disc sliding inside the inner sleeve post installed on the top of the pushing cone block, the top of the sliding disc being connected to the top wall of the positioning post via a reset spring; four spring push posts, equidistantly annularly sliding on the inner sleeve post; an arc plate installed on the outward end of each spring push post, the arc plates being located in the four cavities opened on the outer wall of the positioning post, the outer wall of the arc plate being provided with a compression pad layer, and an inclined push block installed on the inward end of each spring push post.

[0010] In a new embodiment, a sleeve is installed at the bottom end of the propulsion cone, the sleeve slides in a sealed manner within the limiting post, and a through hole is provided on the side wall of the sleeve;

[0011] The outer wall of the propulsion cone has four guide grooves, and an inclined push block slides in each guide groove. The inclined push block and the inner wall of the guide groove form a sliding connection with friction.

[0012] In a new embodiment, an air inlet is installed on the outer side of the limiting post, the air inlet is embedded in the placement plate, and the size of the air inlet is the same as that of the through hole.

[0013] In a new embodiment, a pneumatic valve is fixedly installed in the lower part of the inner cavity of the limiting post. The pneumatic valve is located below the sleeve and is used to adjust the gas pressure entering the inner cavity of the limiting post.

[0014] In a new embodiment, the exhaust assembly includes: a plurality of annular rings, coaxially arranged and embedded inside the placement plate, with their diameters increasing progressively from the inside to the outside; an exhaust pipe, equidistantly spaced on each of the annular rings along the circumference and extending through to the top surface of the placement plate; and a straight air pipe, the body of which is connected to each annular ring, and one end of which is connected to an air inlet on a limiting post.

[0015] In a new embodiment, the drive assembly includes: a hydraulic rod, installed in the middle of the bottom surface of the flat platform; a linkage bar is installed at the telescopic end of the hydraulic rod, and parallel bars are installed at both the front and rear ends of the linkage bar, with three rack segments equidistantly arranged on the outward side of the parallel bars; a gear, located outside the rack segments and meshing with the corresponding rack segments, the gear being fixedly fitted onto the lower part of the corresponding limiting post.

[0016] In a new embodiment, the gas supply assembly includes: an outer shell, installed at the bottom of the flat platform; three bidirectional air pipes, equidistantly installed on the inner wall of the outer shell, each bidirectional air pipe having a cover installed at both ends, and each cover having a sealed rotation limit post; and a main gas supply pipe, the pipe body connecting the three bidirectional air pipes, one end of the main gas supply pipe penetrating the inner wall of the outer shell and extending to the outside, for connecting to an external gas source.

[0017] A processing platform includes a processing platform body and a drilling mold for the intermediate plate.

[0018] Beneficial effects: Compared with the prior art, the advantages of this invention are as follows: 1. The drive box drives the first and second loading plates to rotate, so that the flat table is in a horizontal and parallel state. After the annular middle plate is placed on the placement plate, the initial orientation is manually calibrated. The rotating clamping cylinder completes the initial clamping of the outer side through the clamping plate. Then, the air supply component inputs high-pressure gas into the limiting column, pushing the propulsion cone block to move upward. The inclined push block drives the spring push column to drive the arc plate to expand outward, adaptively locking the middle plate with different inner ring diameters. Finally, through the double clamping of the rotating clamping cylinder and the expansion component, the planar hole is processed by the external drilling equipment. The processing of the outer wall inclined hole only requires rotating the flat table to make it tilted, and then the external drilling equipment can be used to drill the hole. This realizes the one-time clamping and multi-directional fixation of the annular middle plate, avoiding the positioning deviation caused by multiple clamping in traditional discrete processing.

[0019] 2. The expansion assembly is set up with air pressure linkage between the positioning column, inner sleeve column and the propulsion cone. When the high-pressure gas pushes the propulsion cone upward, on the one hand, it causes the through hole of the connected sleeve side wall to be misaligned with the air inlet of the limiting column. On the other hand, the guide groove on the propulsion cone squeezes the inclined push block, which drives the spring push column and the arc plate to expand radially. It can adaptively match the intermediate plate of the ring with different inner diameters without the need for manual adjustment of the tooling, and achieve precise rigid locking of the inner ring. Moreover, when facing the drilling of the inclined hole, the guide groove on the outer wall of the propulsion cone and the inclined push block form a friction fit. The friction between the contact surfaces generates a damping effect, which suppresses the axial movement of the propulsion cone, making the clamping more stable and avoiding hole position displacement caused by severe impact, thus ensuring the machining accuracy of the inclined hole.

[0020] 3. After drilling is completed, the air supply component reduces the air pressure, and the push cone moves down to reset under the action of the return spring. The through hole on the side wall of the sleeve is aligned with the air inlet of the limit post. At this time, the low-pressure airflow forms a fan-shaped air curtain through the annular ring of the exhaust component and the jet pipe, which disperses the drilling debris on the surface of the annular middle plate, avoids the accumulation of debris from affecting the release action of the rotary clamping cylinder, and ensures the continuity of the process.

[0021] 4. The hydraulic rod of the drive component extends and retracts, driving the linkage bar and rack segment to move. The meshing gear drives the limit column and placement plate to rotate. The upper and lower rows of placement plates rotate in opposite directions, so that the inclined holes on the outer wall of the middle plate face outward. With the adjustment of the tilt angle of the plane table, the external inclined holes of multiple ring middle plates are processed by external drilling equipment, without the need for manual flipping of the workpiece.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] This application provides a drilling mold for intermediate plates and a processing platform for its application, which solves the problems of multiple clamping, process dispersion errors, and quality inspection delays caused by discrete processing of intermediate plates, affecting the production efficiency and quality stability of the compressor's core components. In use, the drive box rotates the flat table to parallel, and after the circular intermediate plate is placed and calibrated, the rotating clamping cylinder initially clamps the outer side. The high-pressure gas from the air supply component pushes the arc plate to expand and lock the inner ring. The double clamping completes the processing of the flat hole. The tilting of the rotating flat table realizes the processing of the oblique hole. One-time clamping avoids positioning deviations caused by multiple clamping.

[0036] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0037] Example 1: Please refer to Figures 1-5This application provides a drilling mold for an intermediate plate, comprising: a mounting platform 1; a workbench 2, mounted on the top of the mounting platform 1; a drive box 21 mounted on one side of the top of the workbench 2, and a support plate 22 mounted on the other side of the top; a first loading plate 23 fixedly mounted on the output end of the drive box 21; a second loading plate 24 rotatably mounted on one end of the support plate 22; a flat platform 25 mounted between the first loading plate 23 and the second loading plate 24; two rows of rotary clamping cylinders 3, arranged equidistantly on the front and rear of the top of the flat platform 25; clamping plates 30 mounted on the telescopic ends of the rotary clamping cylinders 3, the clamping plates 30 including a unidirectional short plate 301 and a bidirectional long plate 302; and a placement plate 4, mounted on the top surface of the flat platform 25 and located between two adjacent rotary clamping cylinders 3, with a circular intermediate plate placed on the placement plate 4, and a limit post 5 vertically mounted in the middle of the placement plate 4.

[0038] By configuring a drive box 21, support plate 22, first loading plate 23, second loading plate 24, flat platform 25, rotary clamping cylinder 3, and placement plate 4, the drive box 21 first drives the first loading plate 23, second loading plate 24, and flat platform 25 to rotate, so that the flat platform 25 is parallel to the worktable 2. Then, the annular intermediate plates are placed on each placement plate 4 (the initial orientation needs to be manually calibrated). After placement, the rotary clamping cylinder 3 and the clamping plates 30 (including the unidirectional short plate 301 and the bidirectional long plate 302) are activated to quickly clamp the two rows of annular intermediate plates, reducing the number of manual clamping operations and lowering the cost. Due to positioning errors caused by multiple clamping operations, the annular intermediate plate is then subjected to batch planar drilling using external drilling equipment. When it is necessary to process the oblique holes on the outer wall of the annular intermediate plate, the aforementioned drive box 21, support plate 22, first loading plate 23, and second loading plate 24 drive the planar stage 25 to rotate, causing the planar stage 25 to be in an inclined state. Then, the external drilling equipment completes the oblique hole processing, thereby completing the planar drilling and oblique hole drilling of the annular intermediate plate. Chamfering can also be completed simultaneously, avoiding the time-consuming problem of switching between multiple devices in traditional discrete processing and shortening the processing cycle.

[0039] Example 2: Please refer to Figures 8-12 The limiting post 5 is a hollow shaft structure and all limiting posts 5 are rotatably mounted on the flat platform 25. An expansion component 6 for locking the inner ring of the intermediate plate of the circular ring is installed on the top of the limiting post 5. An exhaust component 7 is provided in the placement plate 4. A drive component 8 is installed on the bottom surface of the flat platform 25 and is used to drive the limiting post 5 and the placement plate 4 fixed thereto to rotate synchronously. An air supply component 9 is installed at the bottom of the flat platform 25 and is used to supply gas into the limiting post 5.

[0040] In the expansion assembly 6, the positioning post 601 is connected to the limiting post 5. The air pressure input by the air supply assembly 9 drives the propulsion cone 603 to radially compress the arc plate 606, which can adapt to the inner ring intermediate plate with different inner ring diameters, so as to achieve precise clamping and locking of the inner ring. At the same time, with the rigid clamping of the outer end face of the annular intermediate plate of the rotating clamping cylinder 3 and the clamping plate 30, a dual fixing mode of inner ring expansion clamping and outer end face rigid clamping is formed, which effectively suppresses processing vibration and ensures the processing accuracy of hole diameter and hole position.

[0041] The drive assembly 8 can drive the placement disk 4 to rotate, thereby causing the inclined drill holes on the outer wall of the circular intermediate plate placed on it to face outward, which facilitates drilling by external drilling equipment (it should be noted that when adjusting the orientation of the inclined drill holes on the outer wall of the circular intermediate plate using the drive assembly 8, the flat table 25 must be in an initial state parallel to the table surface of the worktable 2), thus realizing the processing of inclined holes on the outer wall of the circular intermediate plate and significantly improving the processing efficiency of multi-directional hole systems.

[0042] Please see Figures 7-10 The expansion component 6 includes: a positioning post 601, fixedly installed on the top of the limiting post 5; an inner sleeve post 602, coaxially fixedly installed in the middle of the positioning post 601, and its internal cavity is connected to the inner cavity of the limiting post 5; a pushing cone 603 slides inside the inner sleeve post 602, and a sliding disc 604 is installed on the top of the pushing cone 603, which slides inside the inner sleeve post 602, and the top of the sliding disc 604 is connected to the top wall of the positioning post 601 through a reset spring 6041; four spring push posts 605 are provided, which slide equidistantly in a ring on the inner sleeve post 602; an arc plate 606 is installed on the outward end of each spring push post 605, and the arc plate 606 is located in one of the four cavities opened on the outer wall of the positioning post 601. The outer wall of the arc plate 606 is provided with a compression pad layer, and an inclined push block 6051 is installed on the inward end of each spring push post 605.

[0043] Further, please refer to Figure 8 and Figure 9 A sleeve 607 is installed at the bottom end of the push cone 603. The sleeve 607 is sealed and slides within the limiting post 5, and a through hole 608 is provided on the side wall of the sleeve 607.

[0044] Furthermore, please refer to Figure 10 The outer wall of the push cone 603 is provided with four guide grooves 6031, and each guide groove 6031 has a sliding inclined push block 6051. The inclined push block 6051 and the inner wall of the guide groove 6031 form a sliding connection with friction.

[0045] By setting a positioning post 601, an inner sleeve post 602, a propulsion cone 603, a sliding plate 604, a spring push post 605, and an arc plate 606, the air supply assembly 9 inputs high-pressure gas into the expansion assembly 6 through the limiting post 5. The gas enters the cavity of the sleeve 607 through the inner cavity of the limiting post 5. The high-pressure gas pushes the propulsion cone 603 to slide upward along the inner sleeve post 602. At this time, the sliding plate 604 connected to the propulsion cone 603 moves upward synchronously and compresses the return spring 6041. At the same time, the guide on the outer wall of the propulsion cone 603... The inclined groove 6031 and the inclined push block 6051 form a sliding fit. When the push cone block 603 moves upward, the inclined push block 6051 is squeezed by the inclined surface of the guide groove 6031, which drives the spring push column 605 to move outward radially. The arc plate 606 connected to the outer end of the spring push column 605 extends out of the cavity of the positioning column 601. The compression pad on its outer side is in close contact with the inner wall of the inner ring of the circular ring intermediate plate, realizing the expansion and locking of the inner ring. It can adapt to the circular ring intermediate plate with different inner ring diameters and realize the precise locking of the inner ring.

[0046] Meanwhile, the guide groove 6031 on the outer wall of the push cone 603 forms a friction fit with the inclined push block 6051. The friction between the contact surfaces generates a damping effect, which suppresses the axial movement of the push cone 603, making the clamping more stable and avoiding hole displacement caused by severe impact, thus ensuring the machining accuracy of the inclined hole.

[0047] After drilling is completed, the air supply component 9 switches to low-pressure air supply mode, the air pressure in the limiting column 5 decreases, the reset spring 6041 releases elastic potential energy, pushing the slide 604 and the push cone 603 to reset downwards. When the push cone 603 moves downwards, the squeezing force of the guide groove 6031 on the inclined push block 6051 disappears, and the spring push column 605 retracts inwards under its own elasticity, driving the connected arc plate 606 back into the cavity of the positioning column 601, releasing the middle plate of the ring, and releasing the lock on the inner ring.

[0048] Meanwhile, when the sleeve 607 is reset along with the pusher cone 603, the through hole 608 on the side wall of the sleeve 607 coincides with the air inlet 51 on the limiting post 5 (initially they coincide, but the high-pressure gas squeezes the sleeve 607 upward, and the through hole 608 and the air inlet 51 are misaligned). The low-pressure airflow enters the exhaust assembly 7 through the air inlet 51. The annular ring 701 and the jet pipe 702 of the exhaust assembly 7 convert the low-pressure airflow into a uniform fan-shaped air curtain, which blows the surface of the placement plate 4 at an angle of 30-45° (not shown in the figure). This can quickly disperse the metal chips generated during the drilling process, prevent the accumulation of chips from affecting the rotation or clamping of the workpiece, and improve the cleanliness of the processing and the smoothness of subsequent processes.

[0049] In summary, the high pressure differential ensures the rapid response of the propulsion cone 603 and provides sufficient expansion force to adapt to different inner ring workpieces and achieve rigid locking. At the same time, the air supply component 9 delivers low-pressure pulse airflow to the exhaust component 7 after the sleeve 607 is reset to clean the drilling debris. The external PLC control system precisely controls the switching time difference between high-pressure locking and low-pressure chip removal, forming a closed-loop automated operation of machining, locking and chip removal.

[0050] Please see the figure and Figure 9 An air inlet 51 is installed on the outside of the limiting post 5. The air inlet 51 is embedded in the placement plate 4. The air inlet 51 and the through hole 608 are the same size. By utilizing the overlap of the air inlet 51 and the through hole 608 in the initial state, the low-pressure airflow can be unobstructed. When the high-pressure gas drives the sleeve 607 to move upward, the misalignment of the through hole 608 and the air inlet 51 allows the gas to act on the expansion component 6, thus preventing the high-pressure airflow from leaking.

[0051] Please see Figure 9 A pneumatic valve 52 is fixedly installed in the lower part of the inner cavity of the limiting post 5. The pneumatic valve 52 is located below the sleeve 607 and is used to regulate the gas pressure entering the inner cavity of the limiting post 5. By setting the pneumatic valve 52 to have a built-in pressure sensor and a proportional regulating valve core, the gas pressure entering the inner cavity of the limiting post 5 is dynamically adjusted by receiving electrical signals from the external PLC control system. When the sleeve 607 moves upward under high pressure, the pneumatic valve 52 dynamically adjusts the flow rate by detecting pressure changes to ensure that the expansion force matches the inner ring diameter of the workpiece. When the pneumatic valve 52 switches to the low-pressure gas supply mode, the sleeve 607 resets. At this time, the through hole 608 is connected to the air inlet 51, and the low-pressure airflow forms a uniform blowing air curtain through the exhaust assembly 7.

[0052] Please see Figure 11 The exhaust assembly 7 includes: multiple annular rings 701, coaxially arranged and embedded inside the placement plate 4, with their diameters increasing progressively from the inside to the outside; an air jet pipe 702, equidistantly spaced on each annular ring 701 along the circumference, and extending through to the top surface of the placement plate 4; and a straight air pipe 703, the pipe body of which is connected to each annular ring 701, and one end of which is connected to the air inlet 51 on the limiting post 5.

[0053] By setting up an annular ring 701, jet pipe 702, and straight air pipe 703, when the air supply assembly 9 delivers low-pressure pulse airflow to the limiting post 5, the limiting post 5 discharges gas from the air inlet 51. The airflow is then distributed to the coaxially nested annular ring 701 by the connected straight air pipe 703, and then forms a fan-shaped air curtain covering the entire area of ​​the placement plate 4 at an angle of 30-45° through the circumferentially distributed jet pipe 702. This air curtain alternately blows at multiple frequencies to remove drilling debris, effectively preventing debris from embedding in the clamping mechanism or affecting the workpiece positioning accuracy, ensuring processing continuity and product yield.

[0054] Please see Figure 4and Figure 5 The drive assembly 8 includes: a hydraulic rod 801, which is installed in the middle of the bottom surface of the flat platform 25; a linkage bar 802 is installed at the telescopic end of the hydraulic rod 801, and parallel bars 803 are installed at both the front and rear ends of the linkage bar 802; three rack segments 804 are equidistantly arranged on the outward side of the parallel bars 803; and a gear 805, which is located outside the rack segments 804 and meshes with the corresponding rack segments 804. The gear 805 is fixedly fitted onto the lower part of the corresponding limiting post 5.

[0055] By setting up a hydraulic rod 801, a linkage bar 802, a parallel bar 803, a rack segment 804, and a gear 805, the extension and retraction of the hydraulic rod 801 drives the linkage bar 802 and the parallel bar 803 to move, causing the rack segment 804 on the parallel bar 803 to drive the meshing gear 805 to rotate, thereby driving the limiting post 5 to rotate synchronously with the placement plate 4, causing the circular intermediate plate placed on the placement plate 4 to rotate.

[0056] It should be noted that the annular intermediate plate is placed in a mirror image on the upper and lower rows of placement disks 4, with the center line of the plane stage 25 as the symmetry reference. The drive assembly 8 drives the limiting post 5 and the placement disks 4 to rotate (when the upper row of placement disks 4 rotates counterclockwise, the lower row of placement disks 4 rotates clockwise). This makes the obliquely drilled holes on the outer wall of the annular intermediate plate placed on the placement disks 4 face outward, which is convenient for oblique hole processing. At the same time, by adjusting the corresponding mirror position of the drilling equipment, plane drilling can be performed directly. This layout not only makes full use of the symmetrical structure to optimize the oblique hole processing path, but also achieves compatibility of plane hole processing through equipment adjustment, ensuring the convenience and efficiency of processing two types of holes. Combined with the synchronous locking function of the expansion assembly 6, it significantly improves the processing efficiency and positional accuracy of multi-directional hole systems.

[0057] Please see Figure 4 and Figure 6 The air supply assembly 9 includes: an outer shell 901, installed at the bottom of the flat platform 25; three bidirectional air pipes 902, equidistantly installed on the inner wall of the outer shell 901, each bidirectional air pipe 902 having a cover 903 installed at both ends, and each cover 903 having a sealed rotation limit post 5; and a main air supply pipe 904, the pipe body connecting the three bidirectional air pipes 902, one end of the main air supply pipe 904 penetrating the inner wall of the outer shell 901 and extending to the outside, for connecting to an external air source.

[0058] By setting an outer shell 901, bidirectional air pipes 902, a cover 903, and a main air supply pipe 904, the three bidirectional air pipes 902 are integrated into the outer shell 901 at the bottom of the flat platform 25. The cover 903 is used to achieve a sealed rotational connection of the limiting post 5. The main air supply pipe 904 supplies air to the bidirectional air pipes 902 simultaneously. Under the premise of ensuring no leakage of high-pressure gas, the placement plate 4 is allowed to rotate 360°, realizing dynamic air supply when multiple workpieces are processed in parallel, and ensuring the continuous and stable operation of the expansion assembly 6 and the exhaust assembly 7.
