Abstract
The invention relates to a holddown mechanism for base parts, which is characterized by comprising two finger claw mounting seats. The two finger claw mounting seats are penetratingly arranged on the front side and the rear side of a ball seat joint by a hinge pin, and two holddown finger claws are respectively fixed to the left side and the right side of the bottom of each finger claw mounting seat. The finger claw mounting seats are separately arranged on the front side and the rear side of the ball seat joint, so that the finger claw mounting seats move more flexibly and can move smoothly in optional directions.
Description
Technical field
The present invention relates to a kind of hold-down mechanism that the part of excavator cylinder pedestal is processed of being used for.
Background technology
Regular meeting runs into some behavior tolerances in the metal parts machine components, and the position degree requires product, and a plurality of finished surfaces of this series products require very high with respect to same center degree.As shown in Figure 1, be the workpiece 1 of the excavator base of needs processing, this workpiece 1 has face to be processed 2 and hole 3.
The frock of this workpiece designs and produces complicacy, and product is from great clamping difficulty.Existing as shown in Figure 2 to this Work-sheet pressing mechanism; Comprise that compresses a paw mount pad 5; Ball-joint 4 is located at and is compressed in the paw mount pad 5, is provided with four in the bottom that compresses paw mount pad 5 and compresses 6, four of paws and compress paw 6 and lay respectively on four bights that compress paw mount pad 5.Because this structure adopted ball-joint 4, therefore, the amount of exercise that compresses paw mount pad 5 is limited by itself and frictional force between the ball-joint 4, and motion is very inconvenient.
Summary of the invention
The purpose of this invention is to provide a kind of all directions can both smooth and easy motion hold-down mechanism.
In order to achieve the above object; Technical scheme of the present invention has provided a kind of hold-down mechanism that is used for base part; It is characterized in that; Comprise two paw mount pads, two paw mount pads are located in the both sides, front and back in ball seat joint through a bearing pin, are fixed with a slice respectively in the left and right sides of every paw mount pad bottom and compress paw.
Paw mount pad branch among the present invention is listed in the both sides, front and back in ball seat joint, makes that the activity of paw mount pad is more flexible, no matter in which direction can both smooth and easyly move.
Description of drawings
Fig. 1 is a part sketch map to be processed;
Fig. 2 is former hold-down mechanism sketch map;
Fig. 3 is a kind of front view that is used for the hold-down mechanism of base part provided by the invention;
Fig. 4 is a kind of side view that is used for the hold-down mechanism of base part provided by the invention;
Fig. 5 is a kind of vertical view that is used for the hold-down mechanism of base part provided by the invention.
The specific embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Extremely shown in Figure 5 like Fig. 3; A kind of hold-down mechanism that is used for base part provided by the invention; Comprise two paw mount pads 7; Two paw mount pads 7 are located in the both sides, front and back in ball seat joint 9 through a bearing pin 8, are fixed with a slice respectively in the left and right sides of every paw mount pad 7 bottoms and compress paw 10.
Hold-down mechanism provided by the invention adopts ball seat joint 9 to combine with the paw mount pad 7 of two free states, improves the deflection of mechanism greatly, when the material appearance difference is big, can carry out complementation through this mechanism.
