Abstract
The present invention relates to a kind of workpiece positioning clamp, including bottom plate, be connected at least two opposite hinged blocks on bottom plate, and the pivoted arm being made of upper wraping plate and lower pedal is hinged on each hinged block, is each provided with opening compatible with outer workpiece profile on upper wraping plate.The positioning fixture that obvolvent workpiece is formed between the upper wraping plate that the present invention passes through rotatable pivoted arm, is not necessarily to external impetus, is positioned using workpiece its own gravity, simple in structure, easy to operate, and positioning is rapid, and cost of manufacture is also very low, and cost performance is very high.
Description
Technical field
The invention belongs to a kind of workpiece positioning clamps, and in particular to air-conditioner compressor etc. needs during production and transport
Prevent the positioning clamping of similar work piece toppled over.
Background technology
Compressor of air conditioner, the especially air-conditioner compressor with constant weight are produced in the continuous production line, in order to avoid
Mutual collision causes workpiece to topple over, damage, and needs to carry out quickly positioning fixation to workpiece.Similar workpiece positioning method in the past
Mainly by by the aperture of workpiece bottom, being inserted into positioning pin workpiece is fixed on the work plate of assembly line, but in this way
Positioning method necessarily require the hole of positioning pin on the hole and work plate of workpiece bottom to be aligned, in order to be aligned, need to workpiece revolve
Turn to ensure hole site alignment up and down, therefore be typically by increase checking device, rotating mechanism etc. realizes workpiece positioning, structure
Complexity, of high cost, action is more, and potential faults point is more.
Invention content
It is a kind of without external impetus the purpose of the present invention is overcoming the deficiencies of the prior art and provide, utilize workpiece itself weight
Power, it is simple in structure, easy to operate, positioning is reliable, high performance-price ratio workpiece positioning clamp.
In order to achieve the above object, present invention employs following technical proposals：
A kind of workpiece positioning clamp, including bottom plate, be connected on bottom plate at least two opposite hinged blocks, on each hinged block
It is hinged with the pivoted arm being made of upper wraping plate and lower pedal, is each provided with open compatible with outer workpiece profile on upper wraping plate
Mouthful, such as arc opening.
Using the positioning fixture of this spline structure, it is only necessary to which the workpiece with constant weight is free among opposite pivoted arm
Decentralization, after workpiece contact with the lower pedal of pivoted arm, pivoted arm rotation, when workpiece continues to sink, up to workpiece bottom touches bottom plate,
The upper wraping plate on pivoted arm top relative to each other at this time is by workpiece obvolvent, to play the role of workpiece stationary positioned.
It is further to improve, workpiece holding tray is fixed in the middle part of the bottom plate, the hinged block is arranged in workpiece holding tray
On upper or bottom plate, the groove opposite with lower pedal is further opened on workpiece holding tray.Using the positioning fixture of this structure, work as workpiece
It freely puts down, and when workpiece bottom touches workpiece holding tray, the upper wraping plate on opposite pivoted arm top is by workpiece obvolvent, to rise
To by the effect of workpiece stationary positioned.
Further to improve, the upper wraping plate lower part, which is provided on counterweight or pivoted arm, is fixed with elastomeric element.When workpiece is lifted
When rising, pivoted arm reversely rotates under the action of counterweight or elastomeric element, and the upper wraping plate of obvolvent is opened, and is lifted on lower pedal.It can facilitate
The taking-up of workpiece.
Further to improve, be connected clamping plate on the upper wraping plate, is provided on clamping plate compatible with outer workpiece profile
Opening, such as arc opening.By the way that clamping plate is arranged, can be replaced with different openings according to the exterior contour of different workpiece
Clamping plate, or it is convenient for changing the clamping plate of damage.It is also convenient for by adjusting the distance between clamping plate and upper wraping plate, it is ensured that workpiece bottom connects
When contacting workpiece holding tray, the clamping plate on pivoted arm top consolidates workpiece to play just on the outside of workpiece by workpiece firmly obvolvent
The effect positioned.
The positioning fixture of obvolvent workpiece, the clamp structure are formed between the upper wraping plate that the present invention passes through rotatable pivoted arm
Simply, easy to operate, positioning is rapid, and cost of manufacture is also very low, and cost performance is very high.
Description of the drawings
Fig. 1 is the structural schematic diagram of embodiment 1.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the usage state diagram of embodiment 1.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Embodiment 1：
Workpiece positioning clamp as shown in Figure 1, 2, including bottom plate 1, bottom plate middle part are fixed with workpiece holding tray 5, and workpiece is put
The two opposite hinged blocks 6 that are also connected on the bottom plate of disk both sides are set, are hinged with by upper wraping plate 3 and lower pedal 7 on each hinged block
The pivoted arm of composition, upper wraping plate lower part are provided with counterweight 2.Each also be connected on upper wraping plate clamping plate 4, be provided on clamping plate with outside workpiece
The compatible arc opening of contouring.The groove opposite with lower pedal is further opened on workpiece holding tray.
Using the positioning fixture of this spline structure, it is only necessary to past two pivoted arms relative to each other of the workpiece with constant weight
Centre is put down, and workpiece bottom is contacted with the lower pedal of pivoted arm first, since the weight of workpiece is more than the weight of the counterweight of pivoted arm, work
Part free-falling will drive pivoted arm rotation, as workpiece continues to sink, when workpiece bottom touches workpiece holding tray, and pivoted arm top
Clamping plate by workpiece from both sides obvolvent, to play the role of workpiece stationary positioned.Specific such as Fig. 3.
When needing to take out workpiece, it is only necessary to workpiece be lifted up, due to not having weight to be applied on pivoted arm, turned at this time
Arm reversely rotates under the action of counterweight, and obvolvent lives the clamping plate of workpiece as upper wraping plate is moved toward both sides, is lifted on lower pedal, can
Easily workpiece is taken out.
The invention is not limited in specific implementation modes above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
