Abstract
The invention relates to the technical field of machine tool fixtures, in particular to a mechanical transmission fixture. The mechanical transmission fixture comprises a motor, a speed reducer, a clutch and a transmission shaft, wherein the speed reducer is connected with the motor, the clutch is connected with the speed reducer, and the transmission shaft is in transmission connection with the clutch. A spring support is arranged at the right end of the clutch, and a spring is arranged between the spring support and the clutch; a lead screw transmission device capable of sliding is arranged in the center of the transmission shaft, and the end face of the lead screw transmission device is fixedly connected with a first square clamping block; the lead screw transmission device comprises a nut seat connected with the first square clamping block and a threaded portion which is arranged on the transmission shaft and used in cooperation with the nut seat; the other end of the transmission shaft is provided with a second square clamping block used in cooperation with the first square clamping block. By the adoption of the mechanical transmission fixture, workpiece clamping efficiency is improved.
Description
Technical field
The present invention relates to jig technical field, particularly relate to machine driving fixture.
Background technology
Current machine vice is widely used on milling machine, generally by manually using spanner rotational lead screw during use, driving movable vise body to move, form stepping up and unclamping workpiece by feed screw nut; But the bothersome effort of manual operation, the difference of the qualification of operating personnel, efficiency is also different; And cannot use relatively large workpiece, can only use built-up jig, operation sequence is more complicated.
Summary of the invention
The object of this invention is to provide a kind of machine driving fixture improving Workpiece clamping efficiency.
Technical scheme of the present invention is as follows:
Machine driving fixture, comprises motor, the decelerator be connected with motor, the clutch be connected with decelerator, and the power transmission shaft be connected with driven by clutches; Described clutch right-hand member is provided with spring fastening, is provided with spring between spring fastening and clutch; Described power transmission shaft central authorities are provided with slidably lead screw gear, and the end face of lead screw gear is fixedly connected with the first square fixture block; Described lead screw gear comprises the nut seat be connected with the first square fixture block, and be arranged on power transmission shaft with nut seat with the use of threaded portion; The other end of described power transmission shaft be provided with the first square fixture block with the use of the second square fixture block.
Described the second square fixture block is dismountable is connected to end part of driving shaft; Described the first square fixture block is dismountable is connected to spindle gear end.Removably connect because the first square fixture block and the second square fixture block are, be convenient for changing.
The invention has the beneficial effects as follows: consumed energy is low, use reliable, the clamping force of any size and the translational speed of executive component can be formed; Improve the operating efficiency of holding workpiece.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is motor, and 2 is decelerator, and 3 is clutch, and 4 is power transmission shaft, and 5 is spring fastening, and 6 is spring, and 8 is spindle gear, and 9 is the first fixture block, and 10 is nut seat, and 11 is threaded portion, and 12 is the second fixture block.
Detailed description of the invention
As shown in Figure 1, machine driving fixture, comprises motor 1, the decelerator 2 be connected with motor, the clutch 3 be connected with decelerator 2, and the power transmission shaft 4 be in transmission connection with clutch 3; Described clutch 3 right-hand member is provided with spring fastening 5, is provided with spring 6 between spring fastening 5 and clutch 3; Described power transmission shaft 4 central authorities are provided with slidably lead screw gear, and the end face of lead screw gear is fixedly connected with the first square fixture block 9; Described lead screw gear comprises the nut seat 10 be connected with the first square fixture block 9, and be arranged on power transmission shaft with nut seat with the use of threaded portion 11; The other end of described power transmission shaft be provided with the first square fixture block with the use of the second square fixture block 12.
During use, rotary motion through decelerator, passes to power transmission shaft by dog-clutch from motor; The first square fixture block is driven to do linear reciprocating motion by lead screw gear, and coordinate the second square fixture block by Workpiece clamping, when clamping work pieces, when reaching required clamping force, be contained in the right semi-clutch on slide key, due to the effect of helical teeth, the resistance overcoming spring moves right, there is slipping of clutch phenomenon, motor cuts out.Owing to only in clamping and just need start when unclamping workpiece, save use cost; And can power transmission shaft between the first fixture block and the second fixture block is upper and lower places two workpiece respectively, reduce the clamping workpiece time.
Preferably, the described square dismountable connection of the second fixture block (being threaded) is at end part of driving shaft; The described square dismountable connection of the first fixture block (being threaded) is in spindle gear end.Removably connect because the first square fixture block and the second square fixture block are, be convenient for changing; Even if in the face of large-scale workpiece also can change the first large-scale fixture block and the second fixture block accordingly, can continue to use machine driving fixture.
Claims (2)
1. machine driving fixture, is characterized in that, comprises motor, the decelerator be connected with motor, the clutch be connected with decelerator, and the power transmission shaft be connected with driven by clutches; Described clutch right-hand member is provided with spring fastening, is provided with spring between spring fastening and clutch; Described power transmission shaft central authorities are provided with slidably lead screw gear, and the end face of lead screw gear is fixedly connected with the first square fixture block; Described lead screw gear comprises the nut seat be connected with the first square fixture block, and be arranged on power transmission shaft with nut seat with the use of threaded portion; The other end of described power transmission shaft be provided with the first square fixture block with the use of the second square fixture block.
2. machine driving fixture according to claim 1, is characterized in that, described the second square fixture block is dismountable is connected to end part of driving shaft; Described the first square fixture block is dismountable is connected to spindle gear end.
