Description

Technical Field

[0001] The invention relates to the technical field of drive shaft assembly detection tools, and in particular to a drive shaft assembly detection device. Background Art

[0002] The drive shaft assembly is an important component for transmitting power in a car. It is usually installed between the differential or the final reduction gear and the wheel hub. It includes components such as universal joints and intermediate shafts. During the production process of the drive shaft assembly, the swing angle of the central shaft of the drive shaft assembly needs to be detected to avoid the swing angle between the intermediate shaft and the universal joint being too large or too small.

[0003] At present, when the swing angle of the drive shaft assembly is detected, a special detection tool is required, which has a positioning sleeve and a detection mechanism, and the detection mechanism includes a support rod and a swing angle measuring device. During the measurement process, the universal joint part of the drive shaft assembly is inserted and fixed on the positioning sleeve, and then the shaft body of the drive shaft assembly is swung. When the shaft body swings, it touches and pushes the rack to move. The movement of the rack will drive the pointer to deflect, so that it is convenient to detect whether the swing angle of the shaft body in the drive shaft assembly meets the requirements.

[0004] However, the existing swing angle detection tool can only detect one end of the drive shaft assembly at a time. When the swing angle of the other end needs to be detected, the drive shaft assembly needs to be reversed, which is inconvenient. Therefore, it is necessary to propose a swing angle detection device that does not require the up and down position of the drive shaft assembly to be turned over during detection and can quickly perform swing angle detection on both ends. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a drive shaft assembly detection device.

[0006] The present invention is implemented by the following technical scheme: a housing, wherein two positioning and swinging mechanisms capable of sliding in an arc shape with each other as the axis are arranged in the housing, a limiting mechanism capable of limiting the two arc swinging mechanisms is arranged in the housing, a chuck capable of reciprocating left and right is arranged on the housing, so as to drive the shaft rod of the drive shaft assembly to swing left and right to complete the swing angle detection, two synchronous transmission mechanisms are rotatably arranged in the housing, and an inclinometer capable of rotating and tilting and transmission-connected with the two synchronous transmission mechanisms is arranged on one side of the housing; The positioning swing mechanism comprises a sliding shaft, one end of which extends outside the housing and is fixedly connected to a positioning sleeve capable of limiting the universal joint of the drive shaft assembly, and one end of the two sliding shafts is provided with a same connecting frame; The synchronous transmission mechanism includes a transmission shaft, in which a return spring and a block are arranged, and the upper and lower ends of the connecting frame are provided with slots engaged with the two blocks, so that when one of the positioning and swinging mechanisms is swinging, the other positioning and swinging mechanism will be fixed, and the swinging positioning and swinging mechanism will drive one end of the connecting frame to separate from the corresponding transmission shaft when swinging, and drive the corresponding transmission shaft to rotate through the other end of the connecting frame, thereby driving the inclinometer to tilt through the corresponding transmission shaft.

[0007] As a further improvement of the above scheme, the limiting mechanism includes a sleeve fixedly installed in the outer shell, a limiting rod is slidably arranged in the sleeve, an electric push rod is arranged on one side of the sleeve for driving the limiting rod to rise and fall, and limiting grooves corresponding to the limiting rod are arranged on the two sliding shafts, so that the two sliding shafts can be controlled by the limiting rod to switch between limitation and swinging.

[0008] As a further improvement of the above solution, a reciprocating push-pull mechanism is arranged in the shell, and the reciprocating push-pull mechanism includes a rotatable turntable and a motor for driving the turntable to rotate, and a pull rod for driving the chuck to move back and forth is rotatably arranged on the turntable.

[0009] As a further improvement of the above scheme, a buffer compensation mechanism that can slide left and right is arranged in the shell, and the buffer compensation mechanism includes a sliding rod hinged to one end of the pull rod, and the sliding sleeve on the sliding rod is provided with two buffer springs and a connecting block connected to the chuck. Since the swing amplitude of the shaft rod of the drive shaft assembly driven by the chuck is fixed, the chuck can better adapt to the swing amplitude of the drive shaft assembly through the buffer compensation mechanism.

[0010] As a further improvement of the above solution, the chuck is rotatably connected to the connecting block, so that the chuck can better adapt to the inclination of the shaft of the drive shaft assembly when it swings.

[0011] As a further improvement of the above scheme, a fixing frame connected to the inclinometer is rotatably provided on one side of the housing, and synchronous wheels are sleeved on the shaft rod of the fixing frame and the two transmission shafts, and the three synchronous wheels are sleeved on the same synchronous belt, so that when the fixing frame is driven by the two transmission shafts, the inclinometer can be driven to rotate and tilt, so that the inclination angle of the inclinometer is consistent with the swing amplitude of the shaft rod of the drive shaft assembly.

[0012] As a further improvement of the above scheme, the slot is in the shape of a strip triangle, and the part of the block extending into the slot is also in the shape of a strip triangle, so that when the connecting frame swings, the swinging end can be smoothly separated from the block through the inclined surface of the block, and the rotating end can drive the corresponding transmission shaft to rotate with the help of the block.

[0013] As a further improvement of the above solution, magnets are embedded in the positioning sleeves, so that the drive shaft assembly can be stably confined in the two positioning sleeves.

[0014] As a further improvement of the above scheme, the chuck consists of a disc body and two clamping rods installed on the disc body, the outside of the clamping rod is wrapped with a rubber sleeve, and the middle part of the rubber sleeve is provided with an arc groove, so that the chuck can not only swing the shaft rod of the drive shaft assembly, but also clamp and limit it.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By setting two positioning swing mechanisms and cooperating with limiting mechanisms that can limit the two positioning swing mechanisms, the two positioning swing mechanisms can swing with each other as the axis under the control of the limiting mechanisms, and the axis of the positioning swing mechanism is also consistent with the swing axis of the drive shaft assembly, so that when the drive shaft assembly is placed on the two positioning swing mechanisms, the drive shaft assembly is pushed and pulled by the chuck to realize the swing angle detection of the drive shaft assembly, and the limiting mechanism can quickly adjust the test end of the swing angle detection of the drive shaft assembly, so that the swing angle detection of the drive shaft assembly is more convenient and efficient; Since the swing amplitude of the drive shaft assembly driven by the chuck is fixed (its swing amplitude is usually set to be greater than the swingable amplitude of the drive shaft assembly), in order to prevent the swing amplitude from exceeding the swingable angle of the drive shaft assembly during the swing angle detection of the drive shaft assembly, thereby causing damage to the drive shaft assembly, a buffer compensation mechanism can be provided between the pull rod and the chuck, so that when the chuck drives the drive shaft assembly for the swing angle detection, after the swing angle of the drive shaft assembly exceeds the upper limit, the chuck will squeeze the buffer spring in the opposite direction, so that the chuck can better adapt to the swing amplitude of the drive shaft assembly; In order to allow both sliding shafts to drive the inclinometer to tilt and realize swing angle detection without restricting each other when the two sides swing, a synchronous transmission mechanism composed of a transmission shaft, a clamping block and other structures is set as a transmission member between the two, and the operation is realized through a connecting frame, so that when one of the sliding shafts drives the connecting frame to swing, the swinging end of the connecting frame will disengage from the corresponding transmission shaft, and the rotating end will drive the corresponding transmission shaft to rotate through the clamping block, thereby realizing the synchronous tilt of the inclinometer.

The chuck 15 is mainly used to drive the shaft rod of the drive shaft assembly to swing left and right to complete the swing angle detection. The shell cover and the partition cover of the shell 1 are provided with two arc sliding openings for the positioning swing mechanism to move, and the shell cover is also provided with a parallel sliding opening for the chuck 15 to slide. Two synchronous transmission mechanisms are rotatably provided in the shell 1, and a fixed frame 21 is rotatably provided on one side of the shell 1, and an inclinometer 24 is fixedly installed on the fixed frame 21; The positioning swing mechanism includes a sliding shaft 2, one end of which extends to the outside of the housing 1 and is fixedly connected to a positioning sleeve 3 that can limit the universal joint of the drive shaft assembly. A magnet is embedded in the positioning sleeve 3, so that the drive shaft assembly can be stably limited in the two positioning sleeves 3. One end of the two sliding shafts 2 is rotatably sleeved with the same connecting frame 5. Two limiting clamping rings 201 are also provided on the sliding shaft 2. The two limiting clamping rings 201 are respectively located on both sides of the partition cover of the housing 1. In addition, a positioning rod 202 is also provided on the sliding shaft 2. The inner wall of the main shell of the housing 1 is provided with an arc-shaped slide rail. One end of the positioning rod 202 extends into the arc-shaped slide groove and is slidably connected thereto, so as to ensure the stability of the positioning swing mechanism when sliding. The synchronous transmission mechanism includes a transmission shaft 16, on which a rectangular slide 17 is provided, in which a return spring 18 and a block 19 are slidably installed, and a card slot 20 engaged with two blocks 19 is provided at the upper and lower ends of the connecting frame 5, and the card slot 20 is in a strip-shaped triangular shape, and the portion of the block 19 extending into the card slot 20 is also in a strip-shaped triangular shape, so that when the connecting frame 5 swings, one end of the swinging can be smoothly separated from the block 19 through the inclined surface of the block 19, and the rotating end can drive the corresponding transmission shaft 16 to rotate with the help of the block 19, and when one of the positioning swing mechanisms is swinging, the other One positioning swing mechanism will be fixed, and the swinging positioning swing mechanism will drive one end of the connecting frame 5 to separate from the corresponding transmission shaft 16 when swinging, and drive the corresponding transmission shaft 16 to rotate through the other end of the connecting frame 5, and thereby drive the inclinometer 24 to tilt through the corresponding transmission shaft 16. The shaft rod of the fixed frame 21 and the two transmission shafts 16 are all provided with synchronous wheels 22, and the three synchronous wheels 22 are provided with the same synchronous belt 23, so that when the fixed frame 21 is driven by the two transmission shafts 16, it can drive the inclinometer 24 to rotate and tilt, so that the inclination angle of the inclinometer 24 is consistent with the swing amplitude of the shaft rod of the drive shaft assembly.

[0020] Through the above technical solution, by setting two positioning and swinging mechanisms, and cooperating with a limiting mechanism that can limit the two positioning and swinging mechanisms, the two positioning and swinging mechanisms can swing with each other as the axis under the control of the limiting mechanism, and the axis of the positioning and swinging mechanism is also consistent with the swing axis of the drive shaft assembly, so that when the drive shaft assembly is placed on the two positioning and swinging mechanisms, the drive shaft assembly is pushed and pulled by the chuck 15, so that the swing angle detection of the drive shaft assembly can be realized, and the limiting mechanism can quickly adjust the test end of the swing angle detection of the drive shaft assembly, so that the drive shaft assembly can be placed on the two positioning and swinging mechanisms. The swing angle detection of the shaft assembly is more convenient and efficient. In order to allow both sliding shafts 2 to drive the inclinometer 24 to tilt and realize swing angle detection, and at the same time not restrict each other when the two sides swing, a synchronous transmission mechanism composed of a transmission shaft 16, a clamping block 19 and other structures is set as a transmission member between the two, and the operation is realized through a connecting frame 5, so that when one of the sliding shafts 2 drives the connecting frame 5 to swing, the swinging end of the connecting frame 5 will disengage from the corresponding transmission shaft 16, and the rotating end thereof will drive the corresponding transmission shaft 16 to rotate through the clamping block 19, thereby realizing the synchronous tilt of the inclinometer 24.

[0021] Please combine Figures 5 to 8 The limiting mechanism includes a sleeve 6 fixedly installed in the shell 1, a limiting rod 7 is slidably arranged in the sleeve 6, an electric push rod 8 is arranged on one side of the sleeve 6 for driving the limiting rod 7 to rise and fall, and limiting grooves 4 corresponding to the limiting rod 7 are arranged on the two sliding shafts 2, so that the two sliding shafts 2 can be controlled by the limiting rod 7 to switch between limitation and swing.

[0022] Please combine Fig. 9 A reciprocating push-pull mechanism and a buffer compensation mechanism that can slide left and right are arranged in the shell 1. The reciprocating push-pull mechanism includes a rotatable turntable 10 and a motor 9 for driving the turntable 10 to rotate. The motor 9 and the turntable 10 are provided with mutually meshing bevel gears. A pull rod 11 is rotatably arranged on the turntable 10. The buffer compensation mechanism includes a slide bar 12 hinged to one end of the pull rod 11. Two buffer springs 14 are slidably sleeved on the slide bar 12 and a connecting block 13 rotatably connected to the chuck 15. Two cross bars are arranged on the partition cover of the shell 1. The connecting block 13 is sleeved on the two cross bars and slidably connected to the two cross bars. Since the swing amplitude of the drive shaft assembly driven by the chuck 15 is fixed, the chuck 15 can better adapt to the swingable amplitude of the drive shaft assembly through the buffer compensation mechanism. The chuck 15 is rotatably connected to the connecting block 13, so that the chuck 15 can better adapt to the inclination of the drive shaft assembly shaft when it swings.

[0023] Through the above technical scheme, since the swing amplitude of the drive shaft assembly driven by the chuck 15 is fixed (its swing amplitude is usually set to be larger than the swingable amplitude of the drive shaft assembly), in order to avoid the swing amplitude exceeding the swingable angle of the drive shaft assembly during the swing angle detection of the drive shaft assembly and causing damage to the drive shaft assembly, a buffer compensation mechanism can be provided between the pull rod 11 and the chuck 15, so that when the chuck 15 drives the drive shaft assembly for swing angle detection, after the swing angle of the drive shaft assembly exceeds the upper limit, the chuck 15 will squeeze the buffer spring 14 in the opposite direction, so that the chuck 15 can better adapt to the swing amplitude of the drive shaft assembly.

[0024] The implementation principle of a drive shaft assembly detection device in the embodiment of the present application is: During the inspection, the universal joints at both ends of the drive shaft assembly are placed on the two positioning sleeves 3 respectively, and the shaft rod portion in the middle is clamped between the two clamping rods on the chuck 15. At the same time, in the initial state, the bottom end of the limiting rod 7 is by default clamped into the limiting groove 4 of the sliding shaft 2 below, thereby limiting the sliding shaft 2 below so that it cannot swing; Start the motor 9, which drives the turntable 10 to rotate one circle. When the turntable 10 rotates, the buffer compensation mechanism and the chuck 15 installed on the buffer compensation mechanism move left and right through the pull rod 11, so that the shaft of the drive shaft assembly swings with the universal joint at its bottom as the axis (the axis between the shaft of the drive shaft assembly and the universal joint is coaxial with the sliding shaft 2); At the same time, the sliding shaft 2 at the top, which swings together with the shaft rod of the drive shaft assembly, will drive the top end of the connecting frame 5 to swing together when it swings. The top end of the connecting frame 5 will squeeze the block 19 and be misaligned with it when it swings, so as to separate from the transmission shaft 16 at the top, and the bottom end of the connecting frame 5 rotates with the sliding shaft 2 at the bottom as the axis, and drives the corresponding (lower) transmission shaft 16 to rotate through the block 19 during rotation, and the transmission shaft 16 at the bottom drives the fixed frame 21 and the inclinometer 24 installed on the fixed frame 21 to tilt synchronously through the synchronous wheel 22 and the synchronous belt 23 (because the top end of the connecting frame 5 is disengaged from the block 19 on the upper transmission shaft 16, the synchronous wheel 22 will not be restricted when driving the upper transmission shaft 16 to rotate), so that the inclination angle of the inclinometer 24 is consistent with the swing inclination angle of the shaft rod of the drive shaft assembly, thereby realizing the swing angle detection of the bottom end of the drive shaft assembly; When the swing angle detection of the top end of the driving shaft assembly is required, the electric push rod 8 is started, and the electric push rod 8 drives the limiting rod 7 to limit the sliding shaft 2 located above.
