Description

Technical Field

[0001] The present invention relates to the technical field of transmission housing machining and positioning, and in particular to a positioning device for machining lightweight transmission housings of heavy trucks. Background Art

[0002] In heavy-duty truck manufacturing, the machining quality of transmission cases significantly impacts overall vehicle performance, and positioning equipment plays a key role. Currently, a wide variety of positioning equipment is available on the market for lightweight transmission case machining. These devices can, to a certain extent, meet the positioning requirements of transmission case machining and ensure smooth processing.

[0003] However, existing positioning equipment has significant shortcomings. Its complex structural design and numerous precision components make it difficult to operate, requiring extensive training to become proficient. Furthermore, this complex structure also increases maintenance difficulty and costs. In daily use, if a device malfunctions, repairs are not only time-consuming but also require significant manpower and material resources.

[0004] In view of the problems of complex structure, high use and maintenance costs of existing positioning equipment, the development of a simple-structured and low-cost heavy-duty truck lightweight transmission housing processing and positioning equipment has important economic and practical value. Summary of the Invention

[0005] The main purpose of the present invention is to provide a positioning device for processing a lightweight transmission housing of a heavy truck, so as to solve the problems mentioned in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A positioning device for machining a lightweight transmission housing for a heavy truck includes a workbench on which the lightweight transmission housing for a heavy truck is placed. The housing has a positioning pin hole on the left side and a positioning flat surface on the right side, with a through slot at its center.

[0008] A vertical mounting plate is located on the right side of the workbench. A hydraulic cylinder is affixed to the right end of the mounting plate. The cylinder's telescopic rod slides through the mounting plate, and a positioning plate is hinged at the end of the rod. A positioning block is located on the left end of the positioning plate, which slides into a through-slot. A positioning pin is located on the workbench, which pivots into the positioning pin hole. A first light-transmitting hole is defined in the mounting plate, and a second light-transmitting hole extends through the positioning plate and the positioning block. An infrared transmitter is located on the right side of the mounting plate, and an infrared receiver is located directly below the lightweight transmission housing of the heavy-duty truck. The infrared transmitter, first light-transmitting hole, second light-transmitting hole, and infrared receiver are aligned.

[0009] Furthermore, the end of the telescopic rod is hinged to the positioning plate through a spherical hinge.

[0010] Furthermore, there are two hydraulic cylinders, which are symmetrically arranged along the central axis of the mounting plate.

[0011] Furthermore, a silicone cushion is provided on the left end surface of the positioning plate.

[0012] Furthermore, a control cabinet is provided on one side of the workbench, and the infrared transmitter and the infrared receiver are both electrically connected to the control cabinet.

[0013] The present invention also includes other components that enable the proper operation of this positioning device for lightweight transmission housing machining for heavy trucks. These devices or components utilize conventional techniques in the art. Furthermore, devices and components not otherwise specified in this invention utilize conventional techniques in the art, such as the ball hinge and hydraulic cylinder described herein. During implementation, appropriate device or component models may be selected based on the specific work scenario.

[0014] The working principle of the present invention is as follows: when the lightweight transmission housing of a heavy-duty truck is placed on a workbench, the rotational cooperation of the locating pin and the locating pin hole enables the lightweight transmission housing of the heavy-duty truck to have preliminary positioning and retain self-adjustment capabilities. When the two hydraulic cylinders synchronously drive the telescopic rod to extend, the positioning plate connected by the spherical hinge can adaptively adjust the inclination angle, driving the positioning block to accurately slide into the through groove of the lightweight transmission housing of the heavy-duty truck. During this process, the silicone cushion effectively alleviates the contact impact, and the symmetrically distributed hydraulic cylinders ensure that the positioning plane is balanced in force. When the positioning plate is completely in contact with the positioning plane, the light beam emitted by the infrared transmitter passes through the first light-transmitting hole, the second light-transmitting hole and the through groove in turn, and is captured by the infrared receiver. At this time, the coaxial optical path indicates that the positioning is complete, and the infrared receiver transmits the signal to the control cabinet to form a closed-loop detection, thereby realizing the precise spatial positioning and posture locking of the lightweight transmission housing of the heavy-duty truck.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Reduced equipment use and maintenance costs: The mechanical structure of the equipment is simplified through the rotational matching structure of the locating pin and the locating pin hole and the synchronous drive of the double hydraulic cylinders.

[0017] 2. Improved positioning accuracy and reliability: The positioning plate connected by a spherical hinge has an adaptive adjustment structure and is equipped with a silicone cushion to enable precise sliding into the housing's slot and mitigate impact.

[0018] 3. Enhanced detection system stability: A closed-loop detection system constructed through infrared transmitters and infrared receivers achieves dual verification of spatial positioning and posture locking. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example:

[0027] like Figures 1 to 5 As shown, a positioning device for machining a lightweight transmission housing for a heavy truck includes a workbench 1 on which a lightweight transmission housing 6 for a heavy truck is placed. A positioning pin hole 63 is provided on the left side of the lightweight transmission housing 6 for a heavy truck, and a positioning plane 61 is provided on the right side of the lightweight transmission housing 6 for a heavy truck. A through slot 62 is provided at the center of the positioning plane 61.

[0028] A vertical mounting plate 2 is provided on the right side of the workbench 1. A hydraulic cylinder 3 is fixed on the right end face of the mounting plate 2. The telescopic rod of the hydraulic cylinder 3 slides through the mounting plate 2, and a positioning plate 4 is hinged at the end of the telescopic rod. A positioning block 5 is provided on the left end face of the positioning plate 4, and the positioning block 5 slides in cooperation with the through slot 62. A positioning pin 7 is provided on the workbench 1, and the positioning pin 7 rotates in cooperation with the positioning pin hole 63. A first light-transmitting hole 21 is provided on the mounting plate 2, and a second light-transmitting hole 51 is provided through the positioning plate 4 and the positioning block 5. An infrared transmitter 8 is provided on the right side of the mounting plate 2, and an infrared receiver 9 is provided directly below the lightweight transmission housing 6 of the heavy truck. The infrared transmitter 8, the first light-transmitting hole 21, the second light-transmitting hole 51 and the infrared receiver 9 are in a straight line.

[0029] Specifically, the end of the telescopic rod is hinged to the positioning plate 4 through a spherical hinge. There are two hydraulic cylinders 3, which are symmetrically arranged along the central axis of the mounting plate 2.

[0030] In addition, a control cabinet is provided on one side of the workbench 1, and the infrared transmitter 8 and the infrared receiver 9 are both electrically connected to the control cabinet. A silicone cushion 41 is provided on the left end surface of the positioning plate 4.

[0031] The working principle of the positioning device for processing the lightweight transmission housing of a heavy truck according to the present invention is as follows: when the lightweight transmission housing 6 of a heavy truck is placed on the workbench 1, the rotational cooperation of the positioning pin 7 and the positioning pin hole 63 enables the lightweight transmission housing 6 of the heavy truck to have preliminary positioning and retain the self-adjustment capability. When the two hydraulic cylinders 3 synchronously drive the telescopic rod to extend, the positioning plate 4 connected by the spherical hinge can adaptively adjust the inclination angle, driving the positioning block 5 to slide accurately into the through groove 62. In this process, the silicone cushion pad 41 effectively alleviates the contact impact, and the symmetrically distributed hydraulic cylinders 3 ensure that the positioning plane 61 is subjected to balanced force. When the positioning plate 4 is completely in contact with the positioning plane 61, the light beam emitted by the infrared transmitter 8 passes through the first light-transmitting hole 21, the second light-transmitting hole 51 and the through groove 62 in sequence, and is captured by the infrared receiver 9. At this time, the coaxial optical path indicates that the positioning is completed, and the infrared receiver 9 transmits the signal to the control cabinet to form a closed-loop detection, thereby realizing the precise spatial positioning and posture locking of the lightweight transmission housing 6 of the heavy truck.

[0032] The above embodiments are only descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection of the present invention.
