Description

Technical Field

[0001] This utility model relates to the field of gearbox housing production technology, specifically a hole position detection device for gearbox housing production. Background Technology

[0002] The gearbox housing is a key load-bearing component in the transmission system. Various holes distributed on its surface are used to install core parts such as bearings and gear shafts. The dimensional accuracy, positional accuracy, and integrity of the holes directly affect the assembly quality, operational stability, and service life of the transmission system. Therefore, hole inspection is an important step in the production process of the gearbox housing to ensure that the product is qualified for shipment. Strict control must be exercised over parameters such as the existence of holes, hole diameter, and hole coordinates.

[0003] Modern industrial production increasingly pursues large-scale production and high precision, which places higher demands on the efficiency, accuracy, and adaptability of these hole inspections. However, current inspection methods still have many problems: traditional manual inspection requires moving the housing and adjusting the tools for alignment, which is tiring and slow. Single-piece inspection takes a long time and cannot keep up with the pace of mass production. Moreover, human judgment based on experience is prone to errors, which may result in defective products being released. Some automatic inspection equipment can only inspect specific housing models. Changing to a different specification requires disassembling the tooling and recalibrating, which is troublesome, time-consuming, and affects production.

[0004] Therefore, we propose a hole position detection device for gearbox housing production to solve the problems mentioned above. Utility Model Content

[0005] This utility model provides a hole position detection device for gearbox housing production, which can solve the problems of traditional manual inspection in the prior art. This requires moving the housing and adjusting tools for alignment, which is tiring and slow. The inspection of a single piece takes a long time and cannot keep up with the pace of mass production. Moreover, human judgment based on experience is prone to errors, which may result in unqualified products being released. Some automatic inspection equipment can only test specific housing models. Changing to a different specification requires disassembling the tooling and recalibrating, which is troublesome and time-consuming, affecting production.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A hole position detection device for gearbox housing production includes a conveying unit, wherein the surface of the conveying unit is provided with a detection unit.

[0008] The conveying unit is used to convey the gearbox housing. The conveying unit includes a base, a support frame is fixedly connected to the surface of the base, a conveying frame is installed on the surface of the support frame, a motor is installed on the surface of the base, a lead screw is installed at the output end of the motor, a slide rod is installed on the inner wall of the base, a conveying table is threadedly connected to the surface of the lead screw, and a slot matching the slide rod is opened on the surface of the conveying table. The inner wall of the slot is slidably connected to the slide rod.

[0009] Preferably, a second support frame is fixedly connected to the surface of the base, an electric telescopic rod is installed on the surface of the second support frame, and a limit frame is fixedly connected to the surface of the base.

[0011] Preferably, the two ends of the lead screw are rotatably connected to the inner wall of the base to limit the radial offset when the lead screw rotates.

[0012] Preferably, a baffle is fixedly connected to the surface of the conveyor table. The baffle is used to restrict the conveyor frame from falling into the housing. The baffle passes through the support frame and is slidably connected to the inner wall of the support frame.

[0013] Preferably, the detection unit is used to detect the housing.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] This invention can automatically complete the conveying and hole detection of gearbox housings without manual handling or alignment. The housings automatically fall onto the conveying structure after being stacked, are conveyed to the detection position, and then the detection component completes the detection. Finally, a new housing pushes the detected housing to the limit position. The entire process is continuous and efficient, far exceeding equipment requiring manual intervention. When changing to different housing models for detection, the limit structure can be easily loosened with a simple operation to quickly replace the detection mold. After resetting, it automatically locks, eliminating cumbersome disassembly and assembly steps. This is more convenient and versatile than time-consuming and labor-intensive mold-changing equipment. Furthermore, the buffer design within the conveying structure protects the housings from impacts, and the precise alignment of the detection component with the conveying endpoint ensures accurate alignment during detection, reducing detection errors and part wear caused by positioning deviations. It guarantees detection accuracy while reducing wear, making it highly efficient and reliable. Attached Figure Description

[0025] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0026] Example 1:

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A hole position detection device for gearbox housing production includes a conveying unit 10, and a detection unit 20 is provided on the surface of the conveying unit 10.

[0029] The conveying unit 10 is used to convey the gearbox housing. The conveying unit 10 includes a base 1001, a support frame 1002 fixedly connected to the surface of the base 1001, a conveying frame 1003 mounted on the surface of the support frame 1002, a motor 1004 mounted on the surface of the base 1001, a lead screw 1005 mounted on the output end of the motor 1004, a slide rod 1006 mounted on the inner wall of the base 1001, a conveying table 1007 threadedly connected to the surface of the lead screw 1005, and a slot matching the slide rod 1006 opened on the surface of the conveying table 1007, with the inner wall of the slot slidably connected to the slide rod 1006.

[0030] Through the above technical solution, the base 1001 serves as a basic support component, and a support frame 1002 is fixedly connected to its surface. A conveying frame 1003 is installed on the surface of the support frame 1002, and the conveying frame 1003 is used to stack the gearbox housing to be tested. A motor 1004 is installed on the surface of the base 1001, and a lead screw 1005 is installed at the output end of the motor 1004. A slide rod 1006 is installed on the inner wall of the base 1001, and a conveying table 1007 is threadedly connected to the surface of the lead screw 1005. The surface of the conveying table 1007 has a slot that matches the slide rod 1006, and the inner wall of the slot is slidably connected to the slide rod 1006. By driving the lead screw 1005 to rotate through the motor 1004, the conveying table 1007 can move linearly along the slide rod 1006, thereby realizing the conveying function of the gearbox housing.

[0031] A support frame 1010 is fixedly connected to the surface of the base 1001. An electric telescopic rod 1011 is installed on the surface of the support frame 1010. A limit frame 1009 is fixedly connected to the surface of the base 1001. The limit frame 1009 is used to limit the housing after testing.

[0032] Through the above technical solution, the support frame 1010 fixedly connected to the surface of the base 1001 provides stable support for the electric telescopic rod 1011 installed on its surface, ensuring that the electric telescopic rod 1011 can maintain a stable installation posture during operation; while the limiting frame 1009 fixedly connected to the surface of the base 1001 is specifically used to limit the gearbox housing after the inspection is completed, to prevent the inspected housing from shifting position or falling during subsequent transportation or processing, thereby ensuring the positional stability of the housing after inspection, which is convenient for subsequent collection or further operation.

[0033] The conveying end of the conveying frame 1003 corresponds to the conveying table 1007, and the inner wall of the conveying table 1007 is provided with a buffer pad 1008.

[0034] Through the above technical solution, the conveying end of the conveying frame 1003 corresponds to the conveying table 1007. This setting can ensure that the gearbox housings stacked in the conveying frame 1003 can accurately enter the conveying table 1007 when falling under the action of gravity, avoiding the housings from falling or deviating from the conveying path, and ensuring the accuracy and stability of the feeding process. The inner wall of the conveying table 1007 is provided with a buffer pad 1008, which can form a buffer when the housing falls into the conveying table 1007, reducing the direct collision between the housing and the inner wall of the conveying table 1007, thereby reducing the possibility of damage to the housing due to impact and protecting the structural integrity of the housing.

[0035] The two ends of the lead screw 1005 are rotatably connected to the inner wall of the base 1001 to limit the radial offset when the lead screw 1005 rotates.

[0036] Through the above technical solution, the two ends of the lead screw 1005 are rotatably connected to the inner wall of the base 1001. This connection method provides stable support for the lead screw 1005, ensuring that the lead screw 1005 can rotate smoothly around its own axis under the drive of the motor 1004. At the same time, it restricts the axial movement and radial offset of the lead screw 1005 during rotation, ensuring that the lead screw 1005 can stably drive the conveyor table 1007 with surface thread connection to move accurately along the slide bar 1006 when rotating, thus providing a structural basis for the stable conveying of the gearbox housing.

[0037] A baffle 1012 is fixedly connected to the surface of the conveyor table 1007. The baffle 1012 is used to restrict the conveyor frame 1003 from falling into the housing. The baffle 1012 passes through the support frame 1002 and is slidably connected to the inner wall of the support frame 1002.

[0038] Through the above technical solution, a baffle 1012 is fixedly connected to the surface of the conveyor table 1007, so that the baffle 1012 can move synchronously with the conveyor table 1007. The baffle 1012 passes through the support frame 1002 and is slidably connected to the inner wall of the support frame 1002. This structure provides stable guidance for the movement of the baffle 1012, ensuring that it will not deviate during the movement. The core function of the baffle 1012 is to restrict the falling shell of the conveyor frame 1003. Specifically, when the conveyor table 1007 moves towards the detection unit 20, the baffle 1012 moves with it and blocks the outlet of the conveyor frame 1003, preventing the shell in the conveyor frame 1003 from falling prematurely before the conveyor table 1007 returns. When the conveyor table 1007 returns to the bottom of the conveyor frame 1003, the baffle 1012 moves away with it, and the shell in the conveyor frame 1003 can fall smoothly into the conveyor table 1007, thereby achieving precise control of the timing of the shell falling and avoiding the accumulation of shells affecting the conveying and detection process.

[0039] Example 2:

[0040] Please see Figure 1-4Furthermore, in conjunction with Embodiment 1, it is further obtained that the detection unit 20 is used to detect the shell. The detection unit 20 includes a shell 2001. A groove 2002 is provided on the surface of the shell 2001. A spring 2004 is fixedly connected to the inner wall of the shell 2001. A limiting block 2003 is fixedly connected to the end of the spring 2004 away from the shell 2001. A slider 1 2005 is provided on the surface of the limiting block 2003. A slider 2 2007 is slidably connected to the inner wall of the groove 2002.

[0041] Through the above technical solution, the detection unit 20 is used to detect the housing. It includes a housing 2001, which serves as the basic frame of the detection unit 20, providing structural support. A groove 2002 is formed on the surface of the housing 2001, providing a sliding track for the slider 2007, allowing the slider 2007 to move stably along the groove 2002 to adjust the detection position. A spring 2004 is fixedly connected to the inner wall of the housing 2001. A limit block 2003 is fixedly connected to the end of the spring 2004 away from the housing 2001. The elastic force of the spring 2004 can push the limit block 2003 against the slider 2007. The limiting block 2007 forms a fixed position to ensure the stability of the slider 2007 and the detection components installed on it during the detection process. The surface of the limiting block 2003 is provided with a slider 2005. By moving the slider 2005, the limiting block 2003 can be driven to compress the spring 2004, thereby releasing the limiting of the slider 2007, which facilitates the disassembly or position adjustment of the slider 2007. The inner wall of the slide groove 2002 is slidably connected to the slider 2007, so that the slider 2007 can move smoothly in the slide groove 2002 to adapt to different detection requirements. All components work together to achieve stable detection of the shell and flexible adjustment of the detection components.

[0042] The bottom of slider 2007 is equipped with a detection mold 2006, and a detection column 2008 is installed on the surface of the detection mold 2006.

[0043] Through the above technical solution, a detection mold 2006 is installed at the bottom of the slider 2007, so that the detection mold 2006 can move synchronously with the slider 2007 along the slide groove 2002 of the outer shell 2001 to adjust the detection position. A detection column 2008 is installed on the surface of the detection mold 2006. When the slider 2007 moves the detection mold 2006 to the detection position, the detection column 2008 can align with the hole in the gearbox housing. By measuring the parameters such as whether the detection column 2008 can be accurately inserted into the hole and the depth of insertion, it can be determined whether the hole in the housing meets the design standards, thereby completing the detection function of the hole in the gearbox housing and providing a key basis for product quality control.

[0044] The surface of the housing 2001 is provided with an elongated groove that matches the slider 2005. The elongated groove is used to limit the sliding of the slider 2005.

[0045] Through the above technical solution, the surface of the outer shell 2001 is provided with a long groove that matches the slider 2005. This long groove provides a limited path for the sliding of the slider 2005, allowing it to move only along the direction of the long groove. This ensures that the limiting block 2003, which is fixedly connected to the slider 2005, maintains a stable trajectory during movement. When the detection mold 2006 needs to be replaced, pushing the slider 2005 along the long groove will cause the limiting block 2003 to compress the spring 2004, releasing the lock on the second slider 2007 and enabling the quick disassembly of the detection mold 2006. After replacement, the slider 2005 is released, and the spring 2004 resets, pushing the limiting block 2003 to move in the opposite direction until the slider 2005 is limited by the other end of the long groove. At this time, the limiting block 2003 relocks the second slider 2007, ensuring the stability of the detection mold 2006 during the detection process. By limiting the sliding range of the slider 2005, the long groove effectively ensures the structural reliability and operational convenience of the detection unit 20.

[0046] The top of the outer casing 2001 is fixedly connected to the telescopic end of the electric telescopic rod 1011, which is used to lower the outer casing 2001 for testing.

[0047] Through the above technical solution, the top of the outer shell 2001 is fixedly connected to the telescopic end of the electric telescopic rod 1011. This connection method allows the telescopic movement of the electric telescopic rod 1011 to be directly transmitted to the outer shell 2001. When the electric telescopic rod 1011 extends, it can drive the outer shell 2001 and its internal components such as the slider 2007, the detection mold 2006, and the detection column 2008 to move downwards synchronously, so that the detection column 2008 approaches and inserts into the hole of the gearbox housing to complete the detection. When the electric telescopic rod 1011 retracts, it can drive the outer shell 2001 and related components to move upwards synchronously, so that the detection column 2008 is pulled out from the hole of the housing, making room for the subsequent conveyor 1007 to push the detected housing. At the same time, the fixed connection ensures the stability and accuracy of power transmission, and ensures that the positions of each component of the detection unit 20 are relatively stable during the up and down movement, thereby accurately completing the detection action.

[0048] The bottom end of the detection unit 20 corresponds to the end point of the conveying table 1007.

[0049] Through the above technical solution, the bottom end of the detection unit 20 corresponds to the end point of the conveying table 1007. This positional relationship ensures that when the conveying table 1007 moves along the slide bar 1006 to the end point under the drive of the motor 1004, the detection mold 2006 and detection column 2008 at the bottom of the detection unit 20 can be precisely aligned with the gearbox housing carried on the conveying table 1007, so that the detection column 2008 can be accurately aligned with the hole to be detected in the housing. When the electric telescopic rod 1011 extends and drives the housing 2001 and the detection components to move down, due to the correspondence between the bottom end of the detection unit 20 and the end point of the conveying, the detection column 2008 can be directly and accurately inserted into the hole in the housing to complete the detection. This avoids the detection column 2008 failing to align with the hole or causing collision with the housing due to positional deviation. This is a key position setting to ensure the accuracy and effectiveness of the detection action. At the same time, it provides the basic positional conditions for the housing to be limited and retained by the detection column 2008 when the conveying table 1007 is subsequently retracted.

[0050] Working principle: During use, the gearbox housings to be inspected are stacked inside the conveyor frame 1003 and fall one by one onto the conveyor table 1007 under gravity. The buffer pads 1008 on the inner wall of the conveyor table 1007 protect the housings from collision damage. After the motor 1004 starts, it drives the lead screw 1005 to rotate, which moves the conveyor table 1007 along the slide rod 1006 towards the inspection unit 20. Simultaneously, the baffle 1012 on the surface of the conveyor table 1007 moves with it and blocks the conveyor frame 1003. The outlet of 3 prevents the subsequent housing from falling prematurely; when the conveyor table 1007 moves directly below the detection unit 20, the electric telescopic rod 1011 on the support frame 2 1010 extends, driving the housing 2001 and the slider 2 2007 down along the slide groove 2002. The detection mold 2006 at the bottom of the slider 2 2007 moves down synchronously until the detection post 2008 on the surface of the detection mold 2006 precisely aligns with and is inserted into the housing hole; if the hole meets the standard, the detection post 2008 can be smoothly inserted, at which point the motor... 1004 reverses its rotation, causing the conveyor table 1007 to retract to its initial position. The housing, limited by the detection column 2008, remains in its original position and does not move with the conveyor table 1007. After the conveyor table 1007 returns to its initial position, the baffle 1012 disengages from the outlet of the conveyor frame 1003, and a new housing falls back into the conveyor table 1007. Subsequently, the electric telescopic rod 1011 retracts, the detection column 2008 is pulled out from the detected housing, and the conveyor table 1007, carrying the new housing, moves again towards the detection unit 20. At this time, the conveyor table 1... The thickness of 007, together with the new housing, pushes the previously inspected housing forward until it is blocked by the limit bracket 1009. If it is necessary to adapt to the inspection of different housing models, pushing the slider 2005 can drive the limit block 2003 to compress the spring 2004, thereby releasing the lock on the inspection mold 2006 and making it easy to remove it from the slide 2002. After replacing the new mold, releasing the slider 2005 will reset the spring 2004 and push the limit block 2003 to relock the new mold, and the inspection operation can continue.

Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
