Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor processing technology, and in particular to a processing fixture for a motor base. Background Technology
[0002] A motor mount is a mechanical structural component used to fix, support, and install a motor. A motor mount securely installs the motor in equipment or a system, preventing displacement due to vibration or external forces, ensuring the stability, safety, and accuracy of the motor during operation, while reducing vibration and noise.
[0003] Motor mounts typically require high-precision machining to ensure the stability and alignment of the motor installation. Milling of motor mounts includes machining of reference surfaces, mounting holes, contours, and end faces. While using a vise for milling motor mounts is convenient and versatile, it has several drawbacks that affect machining accuracy and workpiece quality. For example, when machining mounting holes on the side of the motor mount, excessive clamping force can cause warping of the bottom reference surface, affecting subsequent assembly accuracy. Furthermore, the vise's positioning reference is usually fixed to the jaws and bottom surface, making it difficult to guarantee positioning accuracy for motor mounts requiring high precision. Utility Model Content
[0004] This utility model addresses the technical problem of low machining accuracy caused by using a vise clamp in the milling of motor housings. It provides a machining fixture for motor housings, which includes a fixture base and a positioning structure, a clamping structure, and a support component mounted on the fixture base. This design is simple, can accurately position multiple end faces of the motor housing, and effectively avoids the problem of excessive clamping force on the motor housing, thus ensuring the machining accuracy of the motor housing.
[0005] Therefore, the technical solution of this utility model is a machining fixture for a motor base, which includes a fixture base and a positioning structure, a clamping structure and a support member installed on the fixture base. The positioning structure, clamping structure and support member cooperate for the installation, positioning and fixing of the motor base. The positioning structure and the clamping structure are arranged opposite to each other to form a clamping space. The support member includes a left support nail and a right support nail. The support member is installed between the positioning structure and the clamping structure. The clamping structure includes a clamping bracket plate. A clamping bolt is installed on the clamping bracket plate. A clamping block and a clamping spring are provided at the front end of the clamping bolt. A fastening bolt is provided above the clamping bolt. The fastening bolt is connected to the clamping bracket plate by a thread.
[0006] Furthermore, the positioning structure includes a fixed upright plate, on the inner side of which a left support plate and a right support plate are installed.
[0007] Furthermore, a stop pin is provided on one side of the left or right support plate.
[0008] Furthermore, the upper surface of the fixture base is provided with a vertical plate fixing platform and a clamping fixing platform, which are arranged opposite to each other.
[0009] Furthermore, both the upright plate fixing platform and the clamping fixing platform are equipped with positioning pins, and the number of positioning pins is at least two.
[0010] Furthermore, a left support seat and a right support seat are provided between the upright plate fixing platform and the clamping fixing platform, and the left support nail and the right support nail are respectively installed on the left support seat and the right support seat.
[0011] Furthermore, a tool setting platform is provided on one side of the upright plate fixing platform and the clamping fixing platform, and a tool setting block is installed on the tool setting platform.
[0012] Furthermore, the tool setting block can be a standard tool setting block or a right-angle tool setting block.
[0013] Furthermore, the lower surface of the fixture base is provided with a transverse groove and a longitudinal groove.
[0014] Furthermore, a positioning slider is provided in the transverse or longitudinal slide groove.
[0015] The beneficial effects of this utility model are as follows: A machining fixture for a motor base, when the clamping bolt is pulled back, the clamping bolt drives the clamping block to move towards the clamping support plate, and the clamping spring is in a compressed state. At this time, the motor base is placed in the clamping space between the positioning structure and the clamping structure. The lower end face of the motor base is positioned by the left and right support pins, the rear end face of the motor base is positioned by the left and right support plates of the positioning structure, and the left or right end face of the motor base is positioned by the stop pin. When the clamping bolt is released, under the elastic force of the clamping spring, the clamping block moves away from the clamping support plate, and the clamping block presses the front end face of the motor base towards the positioning structure. The pre-clamping force of the motor base is achieved by the elastic force of the clamping spring. Then, the clamping bolt is locked by rotating the fastening bolt downward, thus realizing the installation and positioning process of the motor base. After the motor base is processed, when removing the motor base, first rotate the fastening bolt upward to unlock the clamping bolt, and then pull out the clamping bolt to quickly remove the motor base.
[0016] This structural design enables precise positioning of multiple end faces of the motor mount, effectively avoiding the problem of excessive clamping force. Furthermore, the pre-clamping force of the motor mount can be adjusted by replacing different clamping springs. By setting a tool setting block, the tool height can be calibrated, or the perpendicularity of the tool to the workpiece / fixture can be calibrated, ensuring the machining accuracy of the motor mount.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] like Figures 1-9As shown, this utility model provides a machining fixture for a motor base, which includes a fixture base 1 for connecting to the worktable of a milling machine. A positioning structure 2, a clamping structure 3, and a support member 4 are installed on the fixture base 1. The positioning structure 2, the clamping structure 3, and the support member 4 cooperate to install, position, and fix the motor base 6. The positioning structure 2 is located at the rear end of the upper surface of the fixture base 1, and the clamping structure 3 is located at the front end of the upper surface of the fixture base 1. The positioning structure 2 and the clamping structure 3 are arranged opposite to each other to form a clamping space. The support member 4 is installed between the positioning structure 2 and the clamping structure 3.
[0030] The upper surface of the fixture base 1 is provided with a vertical plate fixing platform 11 and a clamping fixing platform 12. The vertical plate fixing platform 11 and the clamping fixing platform 12 are arranged opposite to each other. The vertical plate fixing platform 11 is used for the installation and fixing of the positioning structure 2, and the clamping fixing platform 12 is used for the installation and fixing of the pressing structure 3. In order to achieve quick installation and accurate positioning of the positioning structure 2 and the pressing structure 3, both the vertical plate fixing platform 11 and the clamping fixing platform 12 are provided with positioning pins, and there are two positioning pins.
[0031] A left support base 13 and a right support base 14 are provided at the middle position between the upright plate fixing table 11 and the clamping fixing table 12. The left support base 13 and the right support base 14 are used for the installation and fixing of the support member 4. The support member 4 includes a left support nail 41 and a right support nail 42. The support member 4 is used to support and fix the lower end face of the motor base 6 and ensure the levelness of the motor base 6. The left support nail 41 and the right support nail 42 are respectively installed on the left support base 13 and the right support base 14. By replacing the left support nail 41 and the right support nail 42 of different sizes, the distance between the lower end face of the motor base 6 and the upper surface of the fixture base 1 can be adjusted to meet the processing requirements of the mounting holes of motor base 6 of different sizes.
[0032] On one side of the vertical plate fixing table 11 and the clamping fixing table 12, there is a tool setting fixing table 15. The upper surface of the tool setting fixing table 15 is provided with a positioning pin. A tool setting block 5 is installed on the tool setting fixing table 15. The tool setting block 5 is a standard tool setting block or a right-angle tool setting block, which is used to calibrate the tool height or calibrate the perpendicularity between the tool and the workpiece / fixture to ensure the machining accuracy.
[0033] The lower surface of the fixture base 1 is provided with a transverse slide 16 and a longitudinal slide 17. A positioning slider 18 is provided in the transverse slide 16 or the longitudinal slide 17 to facilitate the installation and positioning of the fixture base 1 with the worktable of the milling equipment and ensure the machining accuracy.
[0034] The positioning structure 2 includes a fixed upright plate 21. A left support plate 22 and a right support plate 23 are installed on the inner side of the fixed upright plate 21. A stop pin 24 is provided on one side of the left support plate 22 or the right support plate 23. The left support plate 22 and the right support plate 23 are used for positioning the rear end face of the motor base 6, and the stop pin 24 is used for positioning the left end face or the right end face of the motor base 6. The positioning position of the rear end face of the motor base 6 can be adjusted by replacing the left support plate 22 and the right support plate 23 with different thicknesses.
[0035] The clamping structure 3 includes a clamping bracket plate 31, on which a clamping bolt 32 is installed. The upper end face of the clamping bolt 32 is a fixed plane 321. The clamping bolt 32 is slidably connected to the clamping bracket plate 31. The front end of the clamping bolt 32 is provided with a clamping block 33 and a clamping spring 34. After the clamping bolt 32 is installed, the clamping spring 34 is located between the clamping block 33 and the clamping bracket plate 31. A fastening bolt 35 is provided above the fixed plane 321 of the clamping bolt 32. The fastening bolt 35 is perpendicular to the fixed plane 321. The fastening bolt 35 is threadedly connected to the clamping bracket plate 31. The clamping bolt 32 can be locked by the fastening bolt 35.
[0036] When the clamping bolt 32 is pulled back, it causes the clamping block 33 to move toward the clamping bracket plate 31, and the clamping spring 34 is compressed. At this time, the motor seat 6 is placed in the clamping space between the positioning structure 2 and the clamping structure 3. The lower end face of the motor seat 6 is positioned by the left support pin 41 and the right support pin 42, and the rear end face of the motor seat 6 is positioned by the left support plate 22 and the right support plate 23 of the positioning structure 2. The left end face or the right end face of the motor seat 6 is positioned by the stop pin 24. When the clamping bolt 32 is released, the motor seat 6 is compressed. Under the elastic force of the spring 34, the clamping block 33 moves away from the clamping bracket plate 31. The clamping block 33 presses the front end of the motor seat 6 towards the positioning structure 2, and the pre-clamping force of the motor seat 6 is achieved by the elastic force of the spring 34. Then, the clamping bolt 32 is locked by rotating the fastening bolt 35 downward, thus realizing the installation and positioning process of the motor seat 6. After the motor seat is processed, when removing the motor seat 6, first rotate the fastening bolt 35 upward to unlock the clamping bolt 32, and then pull out the clamping bolt 32 to quickly remove the motor seat 6.
[0037] This structural design enables precise positioning of multiple end faces of the motor mount, effectively avoiding the problem of excessive clamping force of the motor mount. Furthermore, the pre-clamping force of the motor mount 6 can be adjusted by replacing different clamping springs 34, ensuring the machining accuracy of the motor mount.
