Technical Field

[0001] The utility model relates to the technical field of motor seat clamps, in particular to a motor seat clamp for a machining center. Background Art

[0002] The electronic starter is what people usually refer to as a motor, also known as a starter. The motor seat is fixed and installed according to the size of the motor. The motor seat needs to be processed during the production process. Most of the existing motor seats use vertical or horizontal machining centers, and need to be fixed with a clamp during the processing.

[0003] In the patent application with the authorization publication number CN214559302U and the authorization publication date 2021-11-02, and the name of "Horizontal machining center workpiece clamp for motor seat production", a lifting unit is provided, which can clamp workpieces of different heights, and a first clamping unit for clamping the top surface of the workpiece is provided on the lifting unit, and a second clamping unit for clamping the bottom of the workpiece is also provided, so that the workpiece clamping is more firm, safe and reliable;

[0004] In the actual use of the above-mentioned device, the workpiece is clamped by the first clamping unit and the second clamping unit. However, this method makes it inconvenient to process the workpiece clamping position, and when processing the workpiece, it is often necessary to perform multi-angle milling on the workpiece, but the device is not convenient for adjusting the angle.

[0005] Therefore, we proposed a machining center motor seat fixture to solve the above problems. Utility Model Content

[0006] 1. Technical problems to be solved by the utility model:

[0007] The purpose of the utility model is to provide a motor seat fixture for a machining center to solve the problems in the current market raised by the above background technology.

[0008] 2. Technical solution:

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a machining center motor seat fixture, comprising a bottom plate installed on the machining center, a base is rotatably installed in the middle of the upper end of the bottom plate, and a gear ring is fixedly sleeved on the bottom outer wall of the base, and a driving gear is meshedly connected to the left side of the gear ring, and a driving gear bearing is installed on the upper left end of the bottom plate, and the end of the driving gear is connected to the output end of the motor;

[0010] The left and right sides of the upper end of the base are fitted with movable rods for sliding installation, and four positioning base plates are arranged above the base, and a connecting rod is rotatably connected between two adjacent positioning base plates, and the left and right positioning base plates are respectively fixed to the upper ends of the left and right movable rods;

[0011] A clamping plate is rotatably mounted on one side of the positioning substrate close to the center of the base, and a rotating mechanism is mounted on the side of the rearmost positioning substrate and the rightmost positioning substrate away from the center of the base, and the rotating mechanism is used to drive the clamping plate to rotate.

[0012] Furthermore, an electric push rod is fixedly mounted on the middle upper end of the base, and an output end of the electric push rod is connected to a receiving plate, and the receiving plate is used to place the motor seat.

[0013] Through the above technical solution, when the electric push rod is started, it can drive the motor seat on the receiving plate to move up and down.

[0014] Furthermore, a bidirectional threaded rod is installed on the internal bearing of the base, and a bevel gear transmission assembly is installed in the middle of the bidirectional threaded rod. The bevel gear transmission assembly consists of two mutually meshing bevel gears, and the two bevel gears are respectively fixed to the middle of the bidirectional threaded rod and the output end of the drive motor, and the drive motor is installed at the upper end of the base.

[0015] Through the above technical solution, when the driving motor is started, the bevel gear transmission assembly can be used to drive the threaded rod to rotate.

[0016] Furthermore, the two movable rods on the left and right are respectively threadedly sleeved on the outer sides of the two ends of the bidirectional threaded rod, and the movable rods and the base form a close left-right sliding connection.

[0017] Through the above technical solution, when the bidirectional threaded rod is rotated, the threaded connection can be used to drive the two movable rods to move relative to each other.

[0018] Furthermore, the rotating mechanism includes a shell fixedly mounted on the rearmost and rightmost side of the positioning substrate, the internal bearing of the shell is equipped with a worm and a worm wheel, and the worm and the worm wheel are meshed with each other, and the ends of the two worm wheels are connected to the ends of the rearmost and rightmost clamps.

[0019] Through the above technical solution, when the worm is driven to rotate, the clamping plate connected to the end of the worm wheel can be driven to rotate.

[0020] Furthermore, the two left and right positioning substrates and the two front and rear positioning substrates are symmetrically distributed about the center of the base.

[0021] The above technical solution enables the motor base to be clamped in multiple directions.

[0022] 3. Beneficial effects:

[0023] By adopting the technical solution provided by the utility model, compared with the prior art, the motor seat fixture of the machining center of the utility model realizes the clamping operation of the motor seat in different directions through the cooperation of four positioning base plates and connecting rods, and can also perform multi-angle processing operations on the motor seat through a rotating mechanism, etc. The specific contents are as follows:

[0024] The motor seat is placed on the receiving plate, and the motor seat above the receiving plate is driven to move to a suitable position by the electric push rod, and then the driving motor is started. The driving motor drives the bidirectional threaded rod to rotate through the bevel gear transmission assembly, and the two movable rods threadedly sleeved on the outside of the bidirectional threaded rod move relatively. When the two movable rods are relatively close to each other, the left and right clamping plates can be driven to clamp the motor seat. When the clamping direction needs to be adjusted, the driving motor is started in the reverse direction. According to the above working principle, the left and right clamping plates are relatively far away from each other, and under the action of the connecting rod, the front and rear clamping plates are pulled relatively close to each other, so that the front and rear clamping plates clamp the motor seat, thereby avoiding processing omissions and improving processing efficiency.

[0025] When multi-angle processing of the motor seat is required, the motor seat is clamped by a clamping plate, and the motor above the driving gear is started. The meshing action between the driving gear and the gear ring is used to drive the motor seat to rotate horizontally. When the worm is driven to rotate, the worm can drive the corresponding clamping plate to rotate by the meshing action between the worm and the worm wheel, thereby driving the motor seat to rotate vertically, realizing multi-angle processing of the motor seat.
