Abstract
The invention discloses an integral type spring clamp claw for a machine tool main shaft swaging clamp, which belongs to the field of machine tools. The integral type spring clamp claw is provided with a main shaft, and an inner cavity of the main shaft is provided with a clamp claw axially. The integral type spring clamp claw is characterized in that the clamp claw is provided with grooves which are machined evenly, and one end of the clamp claw is clamped on a pull rod. The integral type spring clamp claw has the advantages of high reliability, low cost and long service life.
Description
Technical field
The present invention relates to machine tool field, specifically a kind of device that is used for boring and milling drill press spindle part automatic tool changer and cutter is locked.
Background technology
As everyone knows, the spring-loaded pawl that blocks handle of a knife that traditional machine tool is used is a kind of split-type structural, structural principle is, background technology as shown in Figure 1, after split type spring-loaded pawl 1 is processed into several equal portions, make supporter by a rubber ring 3, utilize a spring 4 that split type spring-loaded pawl 1 afterbody is tightened, it is fixed on the axially movable pull bar 6, puts into then in the stationary sleeve 2, thereby realize the opening and closing of split type spring-loaded pawl 1, engaging has O-ring seals 5 on the pull bar 6, because complex structure has increased processing cost on the one hand, assemble waste time and energy (in most cases also wanting on-the-spot the modification) on the other hand.
Summary of the invention
Design existing deficiency in order to overcome original structure, the present invention is designed to monolithic construction with spring-loaded pawl, and the integral spring pawl is simple in structure, is applicable to the automatic tool changer of various large-sized numerical control boring and milling machine main shaft portion, and reduced processing cost, assembling is more easy simultaneously.
Technical scheme of the present invention is: be provided with main shaft, the inner chamber of main shaft is axially installed with claw, it is characterized in that, uniform processing has groove on the claw, and claw one end is fastened on the pull bar.
Effect of the present invention is, the reliability height, and cost is low, and the life-span is long.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of background technology.
Fig. 2 is a structural representation of the present invention.
1. split type spring-loaded pawls among the figure, 2. sleeve, 3. rubber ring, 4. spring, 5.O shape sealing ring, 6. pull bar, 7. main shaft, 8. integral spring pawl, 9. pull bar.
The specific embodiment
In Fig. 2, the inner chamber of main shaft 7 is axially installed with integral spring pawl 8, and uniform processing has groove on the integral spring pawl 8, and integral spring pawl 8 one ends are fastened on the pull bar 9.
Make monoblock type claw 8 move to main shaft 7 dead slot parts by moving axially of pull bar 9, elasticity by claw self is opened, and deliver to claw inside with the blind rivet of cutter this moment, and reverse more mobile pull bar 9 drives claw and gets back in the areola, make integral spring pawl 8 closures, thereby cutter is strained.
Do not need rubber ring as supporter, by changing the material of spring-loaded pawl, uniform processing goes out groove on claw, utilizes the elasticity of metal self to substitute spring, realizes opening with closed of claw.
The integral spring pawl is divided into some lobes uniformly, but keeps certain coupling part between each lobe, coupling part instead of rubber circle is made supporter, and the elasticity of self material substitutes spring.
