Description

Technical Field

[0001] The invention relates to the technical field of drilling, positioning and clamping of automobile parts, and more particularly to an automatic positioning and clamping device for processing automobile parts. Background Art

[0002] Automotive superchargers are one of the most common automotive components, primarily used to increase the intake pressure of the vehicle engine, thereby increasing combustion efficiency and output power. Common supercharger types include mechanical superchargers and turbochargers. The volute (or volute) in an automotive supercharger is a crucial and common component of the turbocharger. Its primary function is to collect exhaust gases from the exhaust side and direct them to the turbine, enabling high-speed rotation. The volute production process generally includes material selection, casting, machining, heat treatment, and surface treatment. During the machining process, mounting holes are drilled in the surface of the cast and pre-formed volute to facilitate subsequent bolt installation of the volute to the vehicle engine.

[0003] At present, when drilling, the volute drilling equipment generally clamps the outer side of the volute through the main clamp, and then fixes the volute by clamping the outer wall of the opening section of the volute through the auxiliary clamp. Then, there are two methods of drilling: multi-axis drilling and single-axis drilling. Single-axis drilling is to control the circular movement of the drill bit to drill holes one by one, while multi-axis drilling is to move multiple drill bits downward synchronously to drill multiple mounting holes at one time. However, the current volute drilling equipment still has certain problems:

[0004] 1. Currently, when fixing the volute, there is a lack of effective connection and locking mechanism between the main fixture and the auxiliary fixture. Due to the independence between the main fixture and the auxiliary fixture, they are prone to loosening or offset during the processing process. Especially in drilling operations with high precision requirements, this instability will lead to drilling position deviation and affect the quality of the final product; 2. The current volute drilling equipment needs to replace the corresponding drilling module when drilling volutes of different specifications (mounting holes with different distribution circle diameters), resulting in poor applicability of the equipment. At the same time, each replacement of the drilling module is not only time-consuming, but may also introduce additional human errors, reducing production efficiency and processing accuracy. Summary of the Invention

[0005] The present invention provides an automatic positioning and clamping device for processing automobile parts, which solves the technical problems in the prior art of needing to replace corresponding drilling modules when drilling volutes of different specifications and lacking an effective connection and locking mechanism between the main clamp and the auxiliary clamp.

[0006] The present invention provides an automatic positioning and clamping device for processing automobile parts, comprising a machine body and a workbench fixedly mounted on the top of the machine body and used for placing a volute, a gantry fixedly mounted on the top of the workbench, a driving member 1 fixedly mounted on the top of the gantry, an output end of the driving member 1 slidingly passing through the gantry and fixedly mounted on a lifting plate, a variable diameter multi-axis drilling unit, a multi-stage locking unit and an inner support fixing unit being provided at the bottom of the lifting plate, the variable diameter multi-axis drilling unit comprising a plurality of drilling assemblies distributed circumferentially and a variable diameter assembly for adjusting the drilling assemblies to drill holes in volutes of different diameters, the multi-stage locking unit comprising a retaining assembly and a locking assembly for performing multi-stage locking and reinforcement on the retaining assembly and the inner support fixing unit;

[0007] The locking assembly includes a fixed cylinder and a locking plate fixedly mounted on the bottom of the fixed cylinder by a return spring, an L-shaped plate fixedly mounted on the left side of the locking plate, a first latch rod fixedly mounted on the bottom of the L-shaped plate, and a plurality of second latch rods distributed circumferentially fixedly mounted on the bottom of the locking plate. The abutting assembly includes an abutting plate for abutting the open end of the volute and a first latch plate fixedly mounted on the top of the abutting plate and cooperating with the first latch rod, and a second latch plate cooperating with the corresponding second latch rod is provided on the outer side of the inner support fixing unit;

[0008] The locking assembly and the retaining assembly cooperate to achieve all-round fixation and locking of the volute.

[0009] Furthermore, a guide column is fixedly installed at the bottom of the lifting plate, and the diameter-changing assembly includes a mounting plate slidably mounted on the outside of the guide column and a plurality of mounting grooves opened on the circumferential surface of the mounting plate and distributed circumferentially, and a sliding rod is slidably connected in the mounting groove.

[0010] Furthermore, an adjusting rod is fixedly passed through one end of the slide rod close to the center of the mounting plate, and the mounting plate is provided with several slide grooves that pass through the mounting groove up and down and are distributed in a circle. The several slide grooves are respectively connected to the corresponding mounting grooves, and the fixing cylinder is fixedly installed at the bottom of the mounting plate.

[0011] Furthermore, an adjustment disk is rotatably installed at the bottom of the mounting disk, and the adjustment disk is rotatably sleeved on the outside of the fixed cylinder. The adjustment disk is provided with a plurality of adjustment slots distributed circumferentially and in an arc shape, and the bottom end of the adjustment rod slides through the slide slot and the corresponding adjustment slot.

[0012] Furthermore, the drilling assembly includes a mounting sleeve fixedly mounted on the bottom of the slide rod via an L-shaped rod and a drive motor fixedly mounted in the mounting sleeve, and a drill bit is fixedly mounted on the bottom end of the output shaft of the drive motor.

[0013] Furthermore, the inner support fixing unit includes a plurality of inner support components distributed circumferentially and a spring telescopic rod fixedly installed at the bottom end of the guide column, and a movable sleeve is provided on the fixed sleeve outside the telescopic section of the spring telescopic rod.

[0014] Furthermore, the internal support assembly includes two hinged rods 1 hinged to the outside of the fixed section of the spring telescopic rod and distributed up and down, and a hinged rod 2 is hinged to the outside of the telescopic section of the spring telescopic rod. The hinged rod 1 and the hinged rod 2 are hinged at one end away from the spring telescopic rod to form an internal support plate for internal support and fixation of the inner wall of the volute.

[0018] 2. By cooperating with the reducing assembly and the drilling assembly, the distribution circle diameter of the drill bit can be adaptively adjusted according to the volutes of different diameters, so as to facilitate drilling of volutes of different specifications. There is no need to replace different drilling assemblies according to the specifications of the volute, thereby greatly improving the applicability of the drilling assembly. At the same time, the entire adjustment process is carried out synchronously, and multiple drill bits move synchronously without deviation, thereby further ensuring the drilling accuracy.

DETAILED DESCRIPTION

[0027] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be varied without departing from the scope of protection of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0028] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4In this embodiment, an automatic positioning and clamping device for processing automobile parts is proposed, including a body 1 and a workbench 2 fixedly installed on the top of the body 1 and used to place a volute 3, a gantry 4 is fixedly installed on the top of the workbench 2, a driving member 5 is fixedly installed on the top of the gantry 4, the output end of the driving member 5 slides through the gantry 4 and is fixedly installed with a lifting plate 6, and the bottom of the lifting plate 6 is provided with a variable diameter multi-axis drilling unit 8, a multi-stage locking unit 9 and an internal support fixing unit 7, the variable diameter multi-axis drilling unit 8 includes a plurality of drilling components 801 distributed on the circumference and a variable diameter component 802 for adjusting the drilling component 801 to drill volutes 3 of different diameters, the multi-stage locking unit 9 includes a retaining component 902 and a locking component 901 for multi-stage locking and reinforcement of the retaining component 902 and the internal support fixing unit 7, and a guide column 10 is fixedly installed on the bottom of the lifting plate 6.

[0029] See Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The inner support fixing unit 7 includes a plurality of inner support components 703 distributed circumferentially and a spring telescopic rod 701 fixedly installed at the bottom end of the guide column 10. A movable sleeve 702 is provided on the outer fixed sleeve of the telescopic section of the spring telescopic rod 701.

[0030] See Figure 3 、 Figure 5 and Figure 6 The inner support assembly 703 includes two hinged rods 7031 hinged on the outside of the fixed section of the spring telescopic rod 701 and distributed up and down. The outer side of the telescopic section of the spring telescopic rod 701 is hinged with a hinged rod 7032. The hinged rod 7031 and the hinged rod 7032 are hinged at one end away from the spring telescopic rod 701 to have an inner support plate 7033 for internal support and fixation of the inner wall of the volute 3. The two hinged rods 7031 serve as supports for the fixed ends to provide stability and guidance for the inner support plate 7033. The hinged rod 7032 is responsible for transmitting motion, converting the axial motion of the telescopic section of the spring telescopic rod 701 into radial motion of the inner support plate 7033.

[0031] See Figure 5 、 Figure 6 and Figure 7 The retaining assembly 902 includes an abutment plate 9023 for abutting the open end of the volute 3 and a second driving member 9024 fixedly installed on the bottom of the workbench 2. A sliding plate 9022 is fixedly installed on the output end of the second driving member 9024. A through groove is provided on the top of the workbench 2 to be slidably connected to the sliding plate 9022. The top of the sliding plate 9022 slides through the through groove and is fixedly connected to the abutment plate 9023.

[0032] When in use, first place the volute 3 to be processed on the top of the workbench 2 and directly below the inner support assembly 703, while making the opening section of the volute 3 on the left and facing the abutment plate 9023. Then, start the second driving member 9024. The output end of the second driving member 9024 pushes the sliding plate 9022 to drive the abutment plate 9023 to move to the right until the abutment plate 9023 contacts the end surface of the opening section of the volute 3. Then stop the second driving member 9024 (as shown in FIG. Figure 2 After that, the cam 7021 of the second cam 7022 is released, and the cam 7023 is released, so that the cam 7022 is in the state of rotation and the cam 7023 is released, thereby the cam 7023 is released, and the cam 7023 is released, so that the cam 7022 is in the state of rotation and the cam 7023 is released.

[0033] See Figure 3 、 Figure 4 and Figure 5 A driving member 3 803 is fixedly installed on the top of the lifting plate 6. The reducing assembly 802 includes a mounting plate 8021 that is slidably mounted on the outside of the guide column 10. The output end of the driving member 3 803 slides through the lifting plate 6 and is fixedly connected to the mounting plate 8021.

[0034] See Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7The locking assembly 901 includes a fixed cylinder 9011 fixedly mounted on the bottom of the mounting plate 8021 and a locking plate 9013 fixedly mounted on the bottom of the fixed cylinder 9011 by a return spring 9012. An L-shaped plate 9014 is fixedly mounted on the left side of the locking plate 9013, which is L-shaped when viewed from above. A locking rod 1 9015 is fixedly mounted on the bottom of the L-shaped plate 9014, and a plurality of locking rods 2 9016 distributed in a circle are fixedly mounted on the bottom of the locking plate 9013. The abutting assembly 902 also includes a locking plate 1 9017 fixedly mounted on the top of the abutting plate 9023 and cooperating with the locking rod 1 9015. A locking plate 2 9018 cooperating with the corresponding locking rod 2 9016 is fixedly mounted on the outer side of the inner support plate 7033. A pressing plate 9021 cooperating with the opening section of the volute is fixedly mounted on the bottom of the L-shaped plate 9014.

[0035] It should be noted that both the latch plate 1 9017 and the latch plate 2 9018 are provided with a number of arc-shaped holes, which are connected in sequence, and the diameters of the arc-shaped holes on the latch plate 1 9017 and the latch plate 2 9018 respectively coincide with the diameters of the latch rod 1 9015 and the latch rod 2 9016, and the opening at the connection between adjacent arc-shaped holes is smaller than the diameter of the arc-shaped holes.

[0036] When in use, after completing the horizontal and circumferential fixation of the volute 3, the output end of the control driving member 3 803 pushes the mounting plate 8021 to move downward, so that the fixing cylinder 9011 pushes the return spring 9012 to drive the locking plate 9013 to move downward. In this process, as the locking plate 9013 gradually moves downward, the L-shaped plate 9014 drives the pressing plate 9021 to gradually approach the opening section of the volute 3 until the pressing plate 9021 is pressed tightly against the outer side of the opening section of the volute 3. Therefore, under the action of the arc-shaped inner side surface of the pressing plate 9021, the volute 3 can be further limited in the circumferential direction, and a certain vertical limit can be provided for the volute 3, thereby further stabilizing the volute 3. At the same time, as the locking plate 9013 gradually moves downward, the locking rod 1 9015 and the locking rod 2 9016 will be driven to move downward synchronously, so that the locking rod 1 9015 and the locking rod 2 9016 are close to the locking plate 1 9017 and the locking plate 2 9018 respectively. When the pressing plate 9021 presses the opening section of the volute 3, the locking rod 1 9015 is inserted into the corresponding arc hole on the locking plate 1 9017, and the locking rod 2 9016 is inserted into the corresponding arc hole on the locking plate 2 9018, thereby locking the abutment plate 9023 and the inner support plate 7033 in the horizontal direction to prevent the abutment plate 9023 and the inner support plate 7033 from loosening during the processing of the volute 3, causing the volute 3 to deviate and affect the processing quality. 4. A tight overall structure is formed between the locking plate 9013 and the inner support plate 7033, thereby realizing multi-stage fixation and multi-stage locking reinforcement operations on the volute 3, improving the positioning and clamping effect during the processing of the volute 3. The double multi-stage design not only enhances the rigidity and stability of the entire fixed structure while ensuring the positioning and clamping effect, but also ensures that during high-precision drilling operations, the volute 3 remains absolutely stationary and will not be displaced due to external interference, thereby greatly improving the drilling accuracy.

[0037] See Figure 3 、 Figure 4 and Figure 5 The variable diameter assembly 802 further includes a plurality of mounting grooves 8022 which are provided on the circumferential surface of the mounting plate 8021 and are distributed in a circumferential manner. A sliding rod 8023 is slidably connected in the mounting groove 8022 .

[0038] It should be noted that the driving member 1 5 , the driving member 2 9024 and the driving member 3 803 can be conventional hydraulic cylinders or pneumatic cylinders.

[0039] See Figure 3 、 Figure 4 and Figure 5The sliding rod 8023 is fixed with an adjusting rod 8025 at one end near the center of the mounting plate 8021. The mounting plate 8021 is provided with a plurality of sliding grooves 8024 that pass through the mounting groove 8022 from top to bottom and are distributed in a circle. The fixing cylinder 9011 is fixedly installed at the bottom of the mounting plate 8021.

[0040] See Figure 3 、 Figure 4 and Figure 5 An adjusting disk 8026 is rotatably installed at the bottom of the mounting disk 8021. The adjusting disk 8026 is rotatably sleeved on the outside of the fixed cylinder 9011. A plurality of adjusting grooves 8027 distributed in a circle and in an arc shape are opened on the adjusting disk 8026. The bottom end of the adjusting rod 8025 slides through the slide groove 8024 and the corresponding adjusting groove 8027.

[0041] It should be noted that the adjustment disk 8026 is driven by an external power source using a gear transmission method (the teeth on the outside of the adjustment disk 8026 are not shown in the figure).

[0042] During specific use, after completing the multi-stage locking and fixation of the volute 3, the adjusting disk 8026 is driven to rotate by an external power supply, so that the adjusting slot 8027 toggles the adjusting disk 8026, driving the adjusting rod 8025 to slide along the adjusting slot 8027, and then driving the slide bar 8023 to slide in the mounting slot 8022. The sliding of the slide bar 8023 will drive the drilling assembly 801 to move through the mounting sleeve 8011, so that the distance from the drilling assembly 801 to the center of the guide column 10 changes, thereby changing the distribution circle diameter of the drill bit 8013, and then adaptive adjustment can be made according to volutes 3 of different diameters, so as to facilitate drilling processing of volutes 3 of different specifications, and there is no need to replace different drilling assemblies 801 according to the specifications of the volute 3, thereby greatly improving the applicability of the drilling assembly 801, and at the same time the entire adjustment process is carried out synchronously, and multiple drill bits 8013 move synchronously without deviation, thereby further ensuring the drilling accuracy.

[0043] See Figure 3 、 Figure 4 and Figure 5 The drilling assembly 801 includes a mounting sleeve 8011 fixedly mounted on the bottom of the slide rod 8023 through an L-shaped rod and a drive motor 8012 fixedly mounted in the mounting sleeve 8011, and a drill bit 8013 is fixedly mounted on the bottom end of the output shaft of the drive motor 8012.

[0044] During specific use, after adjusting the drilling assembly 801, the output end of the control driving member three 803 continues to push the mounting plate 8021 to move downward. At this time, the locking plate 9013 is pressed against the top of the locking plate two 9018, the L-shaped plate 9014 is pressed against the top of the locking plate one 9017, and the pressing plate 9021 is pressed against the outside of the opening section of the volute 3. Therefore, when the output end of the driving member three 803 continues to push the mounting plate 8021 downward, the locking plate 9013 will not move downward, and the mounting plate 8021 will drive the driving motor 8012 to move downward through the sliding rod 8023 and the mounting sleeve 8011, thereby driving the drill bit 8013 to move downward to perform drilling processing on the volute 3.

[0045] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
