A kind of bar grinding apparatus
Technical field
The present invention relates to auto parts and components processing technique field, specifically a kind of bar grinding apparatus.
Background technology
Auto parts and components component part important in being assembled as automobile production, there is strictly processing quality and requirement
Requirement, bar work often as bumper or reinforced connector and used, and bar work generally cannot purchasing initial stage
It directly processes, needs polishing removal surface corrosion layer, pre-processed for following process.In the prior art, generally use abrasive band
Or sand paper polishes to bar work, still, it is uneven that sand paper or abrasive band contact the distribution of forces polished with bar each section, nothing
Method eliminates excessive polishing region, seriously affects the Forming Quality of subsequent product, meanwhile, traditional bar is adopted more when clamping installation
The mode coordinated with chuck and thimble, relies on manual operation, process is cumbersome, and labor intensity is big.
Invention content
In order to avoid with solve above-mentioned technical problem, the present invention proposes a kind of bar grinding apparatus.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of bar grinding apparatus, including pedestal are fixed in mounting base and the mounting base on the pedestal and are connected with
Surge clamp hand, and left side, the right side of the mounting base are equipped with the assembled moving of assembled moving workpiece polishing mechanism and the left and right sides
Workpiece polishing mechanism is arranged symmetrically.
The portable grinder structure includes semicircular sanding block, is moved with the L-shaped Mobile base of sanding block cooperation, with L-shaped
The horizontal pedestal being slidably matched of seat, the pusher cylinder for connecting L-shaped Mobile base, on pedestal and in the leading screw of front and back distribution,
The driving motor being connected with leading screw.The leading screw is mounted on bottom plate, is also equipped on the bottom plate and is set in parallel with leading screw
And the guide rod being slidably matched with pedestal.
The arc bump with itself concentric distribution is equipped on the front end face of the sanding block, rear end face, the L-shaped is moved
It is equipped with the slideway coordinated with arc bump on dynamic seat.
Sanding block positioned at left side is equipped with short pin, and the sanding block for being located at right side is equipped with the pin hole coordinated with short pin.
The tooth of even distribution is equipped on the periphery of the sanding block, the L-shaped Mobile base positioned at right side is equipped with to be nibbled with tooth
The driving gear of conjunction, the driving gear are connected with motor.
Further, steel wire hairbrush is distributed on the inner ring face of the sanding block.
Further, the mounting base is two of front and back setting.
The beneficial effects of the invention are as follows:
The present invention can realize uniformly connecing to bar polishing region each section using two semicircular sanding block cooperations
It touches, it is ensured that polishing is abundant, avoids excessive polishing region from occurring, ensures the Forming Quality of subsequent product, pass through the clamp hand that surges, clamping
Positioning is simple and quick, reduces hand labor intensity, whole equipment is reasonable in design, easy to use, substantially increases work
Efficiency.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structure composition schematic diagram of the present invention;
Fig. 2 is the A-A of Fig. 1 to partial sectional view;
Fig. 3 is the vertical view of the present invention.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, below it is right
The present invention is expanded on further.
As shown in Figure 1 to Figure 3, a kind of bar grinding apparatus, including pedestal 1, be fixed on the pedestal 1 mounting base 2 and
Be connected with the clamp hand 3 that surges in the mounting base 2, left side, the right side of the mounting base 2 be equipped with assembled moving workpiece polishing mechanism and
The assembled moving workpiece polishing mechanism of the left and right sides is arranged symmetrically.
The portable grinder structure includes semicircular sanding block 4, the L-shaped Mobile base 5 coordinated with sanding block 4, is moved with L-shaped
The pusher cylinder 7 of pedestal 6, connection L-shaped Mobile base 5 that dynamic 5 level of seat is slidably matched is mounted on pedestal 6 and is in front and back distribution
Leading screw 8, the driving motor 9 that is connected with leading screw 8.The leading screw 8 is mounted on bottom plate 1, is also equipped on the bottom plate 1 and silk
The guide rod 16 that thick stick 8 is set in parallel and is slidably matched with pedestal 6.
The arc bump 4a, the L with itself concentric distribution are equipped on the front end face of the sanding block 4, rear end face
The slideway 10 with arc bump 4a cooperations is equipped on shape Mobile base 5.
Sanding block 4 positioned at left side is equipped with short pin 11, and the sanding block 4 for being located at right side is equipped with the pin coordinated with short pin 11
Hole 12.
The tooth 13 of even distribution is equipped on the periphery of the sanding block 4, be located at right side L-shaped Mobile base 5 be equipped with
The driving gear 14 that tooth 13 engages, the driving gear 14 are connected with motor 15.
Steel wire hairbrush 4b is distributed on the inner ring face of the sanding block 4.
The mounting base 2 is two of front and back setting.
It is fixed to clamp in the use of the present invention, bar is placed on 3 clamp hand of clamp hand that surges, pusher cylinder 7 starts, and drives
L-shaped Mobile base 5 is moved along pedestal 6, so that the sanding block 4 on left side, right side is cooperated together through short pin 11 and pin hole 12, No.1
Motor 15 starts and driving gear 14 is driven to rotate, and after engaging tooth 13, driving sanding block 4 rotates driving gear 14, then internal
Steel wire hairbrush 4b polish pole 26, driving motor 9 start after, leading screw 8 drive pedestal 6 move forward and backward, along pole 26
Length direction on realize all standing polishing.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
