[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0019] During the assembly of the engine housing, the detection of bevel gear clearance is a crucial step in ensuring the stability and reliability of the transmission system. Currently, bevel gear clearance detection mainly employs manual operation, requiring the housing to be fixed before measurement using a dial indicator and specialized tooling. During measurement, the mechanical positioning accuracy of the tooling directly determines the reliability of the measurement data; insufficient tooling adaptability necessitates changing tooling for different housing models, increasing the cost and time of the inspection. Therefore, existing detection methods are insufficient to meet the quality control requirements of high-precision transmission systems.

[0020] Based on this, an exemplary embodiment of this application provides a bevel gear clearance detection mechanism and a bevel gear detection device. By setting a clamping component, the engine housing can be clamped and positioned to prevent displacement of the engine housing during the detection process, thus affecting the detection accuracy. By setting a first driving component, a second driving component can be moved in a first horizontal direction to adapt to engine housings of different specifications. By setting a second driving component, a third driving component, a gripper component, and a push rod component can be moved in a second horizontal direction to clamp the spline shaft of the first bevel gear in the engine housing. By setting a push rod component, the push rod component can be inserted into the tooth clearance of the spur gear that is connected to the second bevel gear to restrict the rotation of the second bevel gear meshing with the first bevel gear, eliminate external interference, and ensure that the detection only reflects the tooth clearance, resulting in good detection consistency. By setting a third driving component, the first bevel gear can be driven to rotate, thereby measuring the tooth clearance between the first and second bevel gears. This enables fully automatic bevel gear clearance detection with high detection efficiency and good detection consistency.

[0021] Example 1: An exemplary embodiment of this application provides a bevel gear backlash detection mechanism. During the assembly process of an engine housing, detecting the bevel gear backlash is a crucial step in ensuring the stability and reliability of the transmission system. For example... Figure 1As shown, the engine housing includes a spur gear 601, a second bevel gear 602 that is connected to the spur gear 601, and a first bevel gear 603 that meshes with the second bevel gear 602. A splined shaft 604 is provided on the first bevel gear 603. The bevel gear clearance detection mechanism of this application is for detecting the tooth clearance between the first bevel gear 603 and the second bevel gear 602.

[0022] like Figures 2 to 5 As shown, the bevel gear clearance detection mechanism 30 includes a support 301, a clamping assembly 302, a first drive assembly 303, a second drive assembly 304, a first mounting plate 305, a second mounting plate 306, a third drive assembly 307, a floating assembly 308, a gripper assembly 309, and a push rod assembly 310. The clamping assembly 302 is mounted on the support 301 and is used to clamp the engine housing. Preferably, the clamping assembly includes a clamping bracket and a clamping cylinder mounted on the clamping bracket, with the extended end of the clamping cylinder passing through the clamping bracket. When the engine housing needs to be clamped, the clamping cylinder can extend and clamp a preset position on the engine housing to prevent displacement of the engine housing during the detection process. In this application, there can be multiple clamping cylinders; for example, such as... Figure 3 As shown, there are four clamping cylinders, with two cylinders forming a group, which can clamp one size of engine housing. In this way, it can be adapted to different sizes of engine housing.

[0023] The first drive assembly 303 is disposed within the support base 301; the first mounting plate 305 is disposed on the first drive assembly 303; the second drive assembly 304 is disposed on the first mounting plate 305; and the second mounting plate 306 is disposed on the second drive assembly 304.

[0024] The first drive assembly 303 includes a first drive unit 3031, a first connecting seat 3032, and a first guide assembly 3033. The first guide assembly 3033 is disposed on both sides of the first drive unit 3031. The first connecting seat 3032 is disposed on the first mounting plate 305. A second slot 3034 is formed on the first connecting seat 3032, and the protruding end of the first drive unit 3031 is engaged in the second slot 3034. Preferably, the first drive unit 3031 is a cylinder, and the first guide assembly 3033 is a guide rail assembly. In this way, the components on the first mounting plate 305 can move in the first horizontal direction to change the clamping position of the gripper assembly 309 in the first horizontal direction, adapting to different models of engine housings.

[0025] The second slot 3034 on the first connecting seat 3032 is a U-shaped slot. The protruding end of the first driving unit 3031 has appropriate room for movement in the second slot 3034. This not only prevents the first driving unit 3031 from getting stuck when moving in the first horizontal direction, but also allows the protruding end of the first driving unit 3031 to be dislodged from the second slot 3034 when maintenance is required, without having to disassemble the first connecting seat 3032 and other components.

[0026] The second drive assembly 304 includes a second drive unit 3041, a second connecting seat 3042, and a second guide assembly 3043. Both the second guide assembly 3043 and the second drive unit 3041 are mounted on the first mounting plate 305. The second connecting seat 3042 is mounted on the second mounting plate 306. A third slot is formed on the second connecting seat 3042, and the protruding end of the second drive unit 3041 is engaged in the third slot. Preferably, the second drive unit 3041 is a cylinder, and the second guide assembly 3043 is a guide rail assembly. This allows the components on the second mounting plate 305 to move in the second horizontal direction, changing the clamping position of the gripper assembly 309 in the second horizontal direction, thus facilitating the clamping of the spline shaft 604.

[0027] The first end of the second connecting seat 3042 forms a third slot with the opening facing downwards, and the other end is fixed on the second mounting plate 306. This not only prevents the second drive unit 3041 from jamming during movement, but also allows the connection between the second connecting seat 3042 and the second drive unit 3041 to be released simply by removing the second connecting seat 3042 from the second mounting plate 306, which is convenient for maintenance.

[0028] The third drive assembly 307 is mounted on the second mounting plate 306, and a protective cover is provided on the outer surface of the third drive assembly 307. Exemplarily, the third drive assembly 307 includes a third drive unit 3071, a fourth drive unit 3072, a torque sensor 3075, and a coupling 3073; the third drive unit 3071 and the fourth drive unit 3072 are coaxially arranged; the output end of the third drive unit 3071 is sequentially connected to the coupling 3073, the torque sensor 3075, and the coupling 3073. Preferably, the third drive unit 3071 is a motor and a reducer, used to realize the rotational movement of the gripper assembly 309; the fourth drive unit 3072 is a rotary cylinder, used to realize the gripping and releasing of the spline shaft 604 by the gripper assembly 309. The torque sensor 3075 can detect the torque value in real time during the detection gap process.

[0029] In this application, the bevel gear clearance detected by the rotational motion of the third drive component 307 is an angle value. In order to adapt to the detection process in the prior art and facilitate the determination of whether the bevel gear clearance meets the standard according to the detection operation instructions, preferably, a detection ring 3074 is provided on the coupling 3073; a dial indicator 3076 is provided on the top of the protective cover, and the needle of the dial indicator 3076 extends through the protective cover to the detection ring 3074. In this way, while detecting the rotation angle, the bevel gear clearance can be read through the dial indicator 3076, which meets various needs of on-site detection.

[0030] One end of the floating component 308 is connected to the third drive component 307, and the other end is connected to the gripper component 309. For example... Figures 6 to 9 As shown, the floating assembly 308 includes a first floating member 3081, a second floating member 3082, and a third floating member 3083. The first floating member 3081 is fixedly connected to the third drive assembly 307; the second floating member 3082 is fixedly connected to the gripper assembly 309; the third floating member 3083 is disposed between the first floating member 3081 and the second floating member 3082; the third floating member 3083 has a mounting groove extending in a first direction on the side facing the first floating member 3081, and a mounting groove extending in a second direction on the side facing the second floating member 3082; a floating connecting part 3084 is installed in the mounting groove; both the first floating member 3081 and the second floating member 3082 are recessed on the side facing the third floating member 3083, so as to form an installation space for installing the floating connecting part 3084 together with the mounting groove. The floating connecting part 3084 can be a cross roller guide. A mounting base 3085 is provided on both the first floating member 3081 and the second floating member 3082; an elastic element 3086 is provided between each mounting base 3085 and the third floating member 3083. Preferably, the elastic element 3086 is provided in all four directions of the third floating member 3083 (up / down, left / right), and both the third floating member 3083 and the mounting base 3085 are provided with receiving grooves to accommodate the elastic element 3086. Both ends of the elastic element 3086 are respectively accommodated in the receiving grooves, so that the third floating member 3083 can float in the first and second directions. The first and second directions are perpendicular to each other; for example, the first direction can be a vertical direction, and the second direction can be a horizontal direction. Thus, by setting the floating component 308, the gripper component 309 can float in the first and second directions, which can compensate for the positioning deviation of the engine housing. During the clamping process of the spline shaft 604, it can adapt to the position deviation of the spline shaft 604, realize flexible clamping of the spline shaft 604, and avoid problems such as uneven distribution of clamping stress of the spline shaft 604 and affecting the detection accuracy caused by positioning errors of the engine housing.

[0031] Preferred, such as Figure 4As shown, the bevel gear clearance detection mechanism 30 also includes a locking assembly 311, which is mounted on the first mounting plate 305. The locking assembly 311 includes a locking cylinder, a guide block, and a locking pin. The locking cylinder is mounted on the first mounting plate 305, and its extended end is connected to the locking pin. The guide block is mounted on the second mounting plate 306, and the locking pin passes through the guide block. A locking groove 3087 is formed on the mounting base 3085 located below the first floating member 3081. The locking assembly 311 can extend into the locking groove 3087 to lock the floating member 308. Specifically, the locking cylinder can drive the locking pin to move, so that one end of the locking pin extends into the locking groove 3087, causing the floating member to return to the zero position and reset. When the bevel gear gap detection mechanism 30 moves up and down, one end of the locking pin extends into the locking groove 3087, which can prevent the gripper assembly 309 and the floating assembly 308 from rotating during the lifting process and prevent damage to components such as the torque sensor 3075.

[0032] The gripper assembly 309 can be a pneumatic chuck, capable of clamping the spline shaft 604.

[0033] The push rod assembly 310 is mounted on the protective cover. The push rod assembly 310 includes a push rod drive unit 3101, a push rod 3102, and a push rod guide seat 3103. The push rod drive unit 3101 is a cylinder, and the push rod 3102 passes through the push rod guide seat 3103, with a first slot 3105 at one end. The protruding end of the push rod drive unit 3101 is engaged in the first slot 3105, so that the push rod drive unit 3101 and the push rod 3102 are floatingly connected, and it is easy to separate the two for maintenance.

[0034] Preferably, the push rod assembly 310 further includes a support seat 3104, one end of which is disposed on the push rod guide seat 3103, and the other end extends along the stroke direction of the push rod 3102 to form a support portion; the push rod 3102 passes through the support portion, so that the support portion can provide support for the push rod 3102, thereby reducing the cantilever length of the push rod 3102 and reducing the bending deflection of the push rod 3102.

[0035] In this application, there are two push rod assemblies 310, and the two push rod assemblies 310 have different travel directions to adapt to different models of engine housings. One push rod assembly 310 has a travel direction in the second horizontal direction, and the travel direction of the other push rod assembly 310 is set at an acute angle to the second horizontal direction.

[0036] Example 2: An exemplary embodiment of this application provides a bevel gear gap detection device, such as... Figure 10 and 11As shown, the bevel gear clearance detection device includes a frame 10, a lifting drive assembly 20, and the bevel gear clearance detection mechanism 30 described in the embodiment. A conveyor line 40 is provided on one side of the frame, and a tray is provided on the conveyor line 40, which carries the engine housing. The lifting drive assembly 20 is mounted on the frame 10; the bevel gear clearance detection mechanism 30 is connected to the lifting drive assembly 20 in a transmission manner. For example, the lifting drive assembly 20 includes a motor and a chain drive assembly to drive the bevel gear clearance detection mechanism 30 to reciprocate in the vertical direction. Preferably, a counterweight assembly 101 is also provided on the side of the frame away from the bevel gear clearance detection mechanism 30 to provide counterweight for the bevel gear clearance detection mechanism 30, thereby reducing the power of the motor of the lifting drive assembly 20.

[0037] The frame 10 is also equipped with a maintenance rod 102 and a maintenance connector 103, and the support seat 301 of the bevel gear gap detection mechanism 30 is also equipped with a maintenance connector 103. When maintenance is required, due to the large weight of the bevel gear gap detection mechanism 30, in order to prevent accidental movement or falling of the bevel gear gap detection mechanism 30, the maintenance connector 103 on the frame 10 and the maintenance connector 103 on the bevel gear gap detection mechanism 30 can be aligned, and the maintenance rod 102 can be inserted into the connector hole of the maintenance connector 103. Preferably, a detection switch is also provided on one side of the maintenance rod 102 to detect the presence or absence of the maintenance rod 102. When the detection switch does not detect the presence of the maintenance rod 102, the bevel gear gap detection mechanism 30 cannot operate normally to prevent accidental injury to the operator.

[0038] Preferably, a maintenance line 50 is also provided on one side of the conveyor line 40. The maintenance line 50 includes a driven roller. Engine housings that do not meet the test results will move to the maintenance line 50 for maintenance. A blocking and positioning component is provided below the roller of the maintenance line 50 for positioning the pallet.
