Description

Technical Field

[0001] This utility model relates to the field of automated manufacturing of speed reducers, specifically to a speed reducer equipment for machining the fixed contact surface of a horizontal gear housing. Background Technology

[0002] With the development of high-end intelligent manufacturing, the demand for automated and precise tooling for speed reducers and related products is increasing. Currently, there are few fully automated manufacturing processes for gearbox housings of speed reducers with power ratings above 100W. Existing gearbox housing machining mainly relies on manual lathe operation, requiring a pause after each machining cycle to clean the tooling and workpieces, resulting in low production efficiency and significant quality fluctuations. The numerous manual interventions introduce human error, making 24-hour continuous automated production impossible and hindering the intelligent upgrading of the speed reducer manufacturing industry. Utility Model Content

[0003] In view of the above, the purpose of this utility model is to address the problem by providing a speed reducer device for machining the fixed contact surface of a horizontal gear housing.

[0004] This invention provides a speed reducer for machining the fixed contact surface of a horizontal gear housing. It includes a base plate, a fixed plate and guide rail posts set on the base plate, and a guide rail installed between the fixed plate and the guide rail posts. The end of the guide rail is provided with a laterally extending locking part. The guide rail can move and rotate axially. When the gear housing is installed in place, the guide rail rotates to make the locking part rotate inward to the front of the gear housing, and then moves axially to make the locking part press and fix the gear housing.

[0005] Furthermore, a positioning post is provided on the front of the fixing plate, and a conical surface is provided at the end of the positioning post. The conical surface forms a guiding fit with the shaft hole of the gear housing. A fixing pin is also vertically fixed on the fixing plate. The fixing pin fits with the fixing pin hole on the end face of the gear housing to restrict the circumferential rotation of the gear housing.

[0006] Furthermore, a movable plate is installed on the base plate. The movable plate is located on the back of the fixed plate and connected to the guide rail. Reducer A and reducer B are installed on the movable plate. The output shaft of reducer A is connected to a screw, and the screw forms a helical drive with the threaded hole of the fixed plate. The output shaft of reducer B is equipped with a gear, which meshes with a driven gear on the guide rail.

[0007] Furthermore, a production line moving plate is provided, with four pins installed on the bottom of the base plate, at least one of which is used to install a power supply terminal. The production line moving plate is provided with corresponding positive and negative interfaces. After the production line moving plate reaches the designated position, it connects to the external power supply and then supplies power to the power supply terminal through the positive and negative interfaces.

[0008] Beneficial effects: This application can integrate production lines, robotic arms and machine tools to achieve 24-hour closed-loop processing without human intervention, thus greatly improving production efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 13 The reducer equipment shown is used for machining the fixed contact surface of a horizontal gear housing. It includes a base plate 1, which supports various components and has four mechanical claws 101 on its outer side for use with a robotic arm. Below the base plate 1 is a conveyor plate 2 for transporting the base plate 1 along the conveyor line. The base plate 1 has a fixed plate 3 and guide rail posts 4 opposite to the fixed plate 3. The fixed plate 3 has a positioning post 301 on its front side, the end of which is designed as a conical surface to form a guiding engagement with the output shaft hole 501 of the gear housing 5, enabling rapid machining of the gear housing 5. The positioning plate 3 is quickly fitted in, and a fixing pin 302 is vertically fixed on the fixing plate 3, which is precisely aligned with the fixing pin hole 502 on the end face of the toothed shell 5. After insertion, the toothed shell 5 is restricted from circumferential rotation. A guide rail 6 is installed on the fixing plate 3 and the guide rail post 4. The guide rail 6 can move and rotate axially. The end of the guide rail 6 is provided with a laterally extending locking part 601. When the toothed shell 5 is installed in place, the guide rail 6 can rotate to allow the locking part 601 to rotate inward to the front of the toothed shell 5. Then, the guide rail 6 moves axially to allow the locking part 601 to press the toothed shell 5 tightly, thus completing the fixation.

[0022] In a preferred embodiment, a movable plate 7 is mounted on the base plate 1. The movable plate 7 is located on the back of the fixed plate 3 and connected to the guide rail 6. A reducer A9 and a reducer B10 are mounted on the movable plate 7. The output shaft of reducer A9 is connected to a screw, which forms a helical transmission with the threaded hole of the fixed plate 3, driving the movable plate 7 to move axially along the sliding groove of the base plate 1, thereby causing the guide rail 6 to move axially synchronously. The output shaft of reducer B10 is equipped with a gear 101, which meshes with a driven gear 602 on the guide rail 6 to control the rotation of the guide rail 6.

[0023] In a preferred embodiment, four pins 102 are installed on the bottom of the base plate 1, at least one of which is equipped with a power terminal 103. The production line moving plate 2 is provided with corresponding positive and negative interfaces 201. After the production line moving plate 2 reaches the designated position, it connects to the external power supply and then supplies power to the power terminal 103 through the positive and negative interfaces 201. The bottom of the base plate 1 is also provided with three normally closed switches A11 connected in series with the power terminal 103. Only when the base plate 1 is placed horizontally and stably, the three switches close synchronously to form a power circuit, avoiding the risk of accidental start-up caused by equipment tilting.

[0024] In a preferred embodiment, the base plate 1 is equipped with a touch-type wire exchanger 12, which internally includes a rotating conductive plate 1201, as well as copper plates A1202 distributed vertically and copper plates B1203 distributed horizontally. The rotating conductive plate 1201 achieves rotation switching through the meshing of a one-way gear and a driven gear, controlling the on / off state of the circuit. Specifically, the driven gear drives the one-way gear to rotate by pressing the spring rod 1204, and the rotating conductive plate 1201 rotates unidirectionally, that is, it rotates 90 degrees for switching with each press. The spring rod 1204 resets and does not drive the rotating conductive plate 1201 to rotate. In addition, the base plate 1 is equipped with an information transmitting board 17, which integrates a normally open switch A13 and a signal transmitting device; the fixed plate 3 has a normally closed switch B14 on the front and a normally closed switch C15 on the back; the movable plate 7 has a normally open switch B16 on the back. The wiring of each switch is hidden through wire holes to ensure circuit safety.

[0025] The working principle and workflow of this application:

[0026] I. Preparing for Processing and Installation

[0027] 1. The base plate 1 is placed on the moving plate 2 of the production line, and the rotating conductive plate 1201 of the touch-type wire exchanger 12 rotates to connect with the copper plate B1203.

[0028] 2. When the base plate 1 is placed on the moving plate 2 of the production line in a specified horizontal state, the three series-connected normally closed switches A11 at the bottom of the base plate 1 are closed at the same time, and the power supply terminal 103 is connected to the power supply terminal 103, keeping the circuit conductive.

[0029] 3. When the conveyor moving plate 2 reaches the designated location, the conveyor moving plate 2 is connected to the external power supply. The robotic arm puts the output shaft hole 501 of the toothed shell 5 into the positioning post 301. The fixed plate 3 is provided with an inclined surface 303 that corresponds to the two fixed feet of the toothed shell 5. It can be used to determine the position of the fixed feet and guide the fixing pin 302 on the fixed plate 3 to be correctly inserted into the fixing pin hole 502. When the end face of the toothed shell 5 is in contact with the fixed plate 3, the normally closed switch B14 on the end face of the fixed plate 3 is triggered to close.

[0030] 4. The reducer B10 rotates clockwise, driving the gear 101 to rotate. Through the cooperation of the gear 101 and the driven gear 602, the locking part 601 at the end of the guide rail 6 rotates to the front of the gear housing 5. After the guide rail 6 rotates to the position, the normally open switch B16 on the back of the moving plate 7 is triggered, the reducer B10 is closed, and the reducer A9 starts to rotate counterclockwise, pushing the moving plate 7 away from the fixed plate 3, so that the guide rail 6 moves axially and drives the locking part 601 at the end to lock the gear housing 5.

[0031] 5. After locking, the moving plate 7 contacts the normally open switch A13 on the signal transmitter board. The normally open switch A13 closes, the power is cut off, and the transmitter device inside the signal transmitter board sends an installation completion signal. The robotic arm grips the robotic claw buckle 101 and sends the base plate 1 into the machining center as a whole.

[0032] II. Disassembly after processing:

[0033] 1. The robotic arm grips the mechanical claw 101 and transfers the base plate 1 onto the production line moving plate 2. The rotating conductive plate 1201 of the touch-type wire exchanger 12 switches and connects with the copper plate A1202.

[0034] 2. The base plate 1 is placed horizontally, the three normally closed switches A11 are closed, the reducer A9 rotates clockwise, pushing the moving plate 7 to move towards the fixed plate 3, touching the normally closed switch C15 on the fixed plate 3, the reducer A9 is turned off, and the locking part 601 moves away from the gear housing 5.

[0035] 3. The reducer B10 starts to rotate counterclockwise, which drives the gear 101 to rotate, causing the locking part 601 to rotate outward, triggering the active switch B16 on the moving plate 7 to close, the reducer B10 to shut down, and the transmitter set in the signal transmitting device sends a disassembly completion signal. The robotic arm then sends the gear housing 5 into the next process.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
