The connecting plate (1) is mounted at one end of the balance rolling shaft (2), the balance plate (3) is mounted at the other end of the balance rolling shaft (2), support pins (5) are disposed on the periphery of the balance plate (3), and the balance weights (4) are mounted on the support pins (5). The lathe jig static balance device realizes practicability of the principle of static balance, overcomes incorrectness of rough estimation, and has simple structure and convenient use.
Description
Technical field
The utility model belongs to turning attachment and adjusts equipment technical field, relates to a kind of turning attachment static balancing apparatus concretely.
Background technology
At present, anchor clamps if the general structure imbalance of anchor clamps then will cause vibration under action of centrifugal force, influence the machining accuracy and the surface roughness of workpiece in company with main axis rotation during owing to machined into, the wearing and tearing of aggravation machine tool chief axis and bearing.Therefore, turning attachment overhangs except control the length, also should be in a basic balance on the structure.There is following problem in the static balance of turning attachment at present: the general balance method that adopts has two kinds, and balance weight or processing lightening hole promptly are set.When the weight of determining balance weight or weight that lightening hole is removed, make approximate estimation with isolation method.Promptly each element on workpiece and the anchor clamps, be isolated into several sections, the each several part of balance can omit and disregard mutually, to unbalanced part, then determines the weight of balance weight or the weight that lightening hole should be removed by principle of moment balance.In order to remedy the inaccuracy of estimation algorithm, (or on clamp body) has radial slot or cannelure on the balance weight, so that adjust.The method is more coarse, and the counterbalance effect of anchor clamps is also bad.And the employing dynamic balancing then needs special-purpose dynamic balancing machine, and its expense height is not suitable for general factory reality.
The utility model content
The purpose of this utility model is statically balanced principle practicability, overcomes the inaccuracy of estimation, and a kind of static balancing apparatus of turning attachment is provided, and this apparatus structure is simple, and is easy to use.
The technical solution of the utility model is as follows:
A kind of turning attachment static balancing apparatus, this device comprise terminal pad, the balance axis of rolling; Balancing frame and counterpoise, described terminal pad are contained in an end of the described balance axis of rolling, and balancing frame is contained in the other end of the described balance axis of rolling, and the circumference of described balancing frame is provided with the support pin, adorn described counterpoise on this support pin.
Said structure is simple, easy to use can accurately measure non-equilibrium site and weight, thereby adjusts anchor clamps.
Described balancing frame one end that is equipped with is provided with clamp nut.
Beneficial effect: the utility model with statically balanced principle practicability, overcome the inaccuracy of estimation, a kind of static balancing apparatus of turning attachment is provided, this apparatus structure is simple, and is easy to use.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
The specific embodiment
Embodiment: as shown in Figure 1, 2: a kind of turning attachment static balancing apparatus is characterized in that: this device comprises terminal pad 1, the balance axis of rolling 2; Balancing frame 3 and counterpoise 4, described terminal pad 1 is contained in an end of the described balance axis of rolling 2, and balancing frame 4 is contained in the other end of the described balance axis of rolling 2, and the circumference of described balancing frame 4 is provided with and supports pin 5, adorns described counterpoise 4 on this support pin 5.Described balancing frame 4 one ends that are equipped with are provided with clamp nut 6.
Practical approach of the present utility model and principle:
The utility model and grinding wheel balancer 7 are used, earlier with grinding wheel static balancing frame 7 adjustment levels, then turning fixture 8 is contained on the terminal pad 1, take off all counterpoises 4, whole static balancing apparatus is put on the guide rail of grinding wheel static balancing frame 7 of leveling, apply the suitable external force bascule that rolls more than 2 times, after it is static, more than 2 times all when same position stops (the anchor clamps minimum point on the terminal pad 1 is uneven position, heavier position), unclamp locking nut this moment, with there being the hole site to forward 12 o ' clock positions on the balancing frame (is the peak of vertical direction, symmetrical with heavier part anchor clamps minimum point, as Fig. 2), and add counterpoise, make its in the vertical direction weight reach balance this moment.Apply suitable external force and repeatedly all stop at an arbitrary position up to the rolling bascule, at this moment think the uneven weight of anchor clamps be exactly add the weight of counterweight, its direction is on the opposite of wearing counterweight, its unbalanced mass-radius product is the product of M counterweight and R.According to the weight and the position of counterweight, unload lower clamp, remove the weight (weight of removal only need guarantee that mass-radius product equates to get final product with the M*R value) of anchor clamps relevant position.The anchor clamps of removing weight are contained on the bascule, repeat preceding step, up to not adding counterweight, bascule can stop on guide rail at an arbitrary position, realizes static balance.Check its amount of unbalance with the counterpoise of 5g, behind the counterpoise that adds 5g, observe bascule and whether stop at an arbitrary position.If then readjust, if not then also satisfy the balance requirement.
Uneven accuracy computation sees that R is 75mm among Fig. 2, and when with the 5g counterpoise, its unbalanced mass-radius product is 0.375g.m.
The analogy dynamic balancing is calculated as follows: the working speed of establishing anchor clamps is 2000 rev/mins, and the anchor clamps quality is 20 kilograms, asks balance quality allowable [e] and uneven mass-radius product m.[e allowable].By checking in G6.3 on the ISO1940-1986 balance accuracy grade table.Be A=6.3.
The angular velocity omega of anchor clamps=n π/30, then: [e]=1000xA/ ω=30mm
Uneven mass-radius product m[e allowable]=20x30Kgmm=60gcm=0.6gm
The allowable uneven mass-radius product of contrast dynamic balancing G6.3 level, this bascule best level 0.375g.m＜0.6gm.
The counterpoise of getting 10g in the practical application just can satisfy, and the generally anchor clamps instructions for use of numerically controlled lathe can reach the allowable uneven mass-radius product scope of ISO1940-1986 balance quality G16.
Above bascule is particularly suitable for the balance test of digital control lathe clamper, general vehicle clamper.This utility model also is applied in production practices, several vehicle clampers of test through static balancing apparatus, and processing experiment on numerically controlled lathe, lathe is not made fot screw and is fixed, and only does the leveling support, and rotating speed is during to 2000r/min, and obvious vibration does not take place in lathe.
