Description
Technical field
The utility model relates to the apparatus for impact testing field, relates in particular to a kind of impact testing machine.
Background technology
Material is when doing impulse test, and the pendulum on the impact testing machine is kicked up, impacted by computer control.When changing sample in process of the test, need the operation pendulum to be raised up to the state of raising in advance, then the staff changes sample.Yet present impact testing machine is not enough to some extent to protection in such cases; do not have the whereabouts protection structure when having for the tup off working state; if people's maloperation is arranged this moment or falls to carrying out percussion action because mechanical disorder causes pendulum, will cause great personal injury to changing the sample staff.When therefore existing impact testing machine can't be avoided the unexpected whereabouts of tup the staff is damaged.
China Patent Publication No. CN201392297Y, open day on January 27th, 2010, the name of utility model is called a kind of drop hammer impact testing machine, this application case discloses a kind of drop hammer impact testing machine, it is by buting iron, suspension hook, wire rope, claw hook device, rail clamping device forms, it is characterized in that: crossbeam, column, stull, support, be bolted and consist of the drop hammer impact testing machine skeleton, pulley is fixed on the crossbeam, pulley is fixed in the column below, wire rope one end is fixed on the crossbeam, the other end passes suspension hook, pulley is connected on the propulsion system, suspension hook is risen to the bait and is useful on the claw hook device of pick-and-place ram hammer, centre position, rail clamping device vertical columns below.This utility model weak point is still the whereabouts protection structure when not having for the tup off working state, in the time of can't avoiding the unexpected whereabouts of tup the staff is damaged.
The utility model content
The utility model has overcome existing impact testing machine can't avoid the deficiency that can damage the staff when tup is unexpected when falling, and a kind of impact testing machine that can protect operating personnel when the unexpected whereabouts of tup is provided.
The utility model is achieved through the following technical solutions:
A kind of impact testing machine, comprise base, fuselage, described base is provided with clamping device, described fuselage is provided with the fork hinged with back, described fork lower end is provided with tup, be provided with the fork position limiting structure between described fork and the clamping device, described fork position limiting structure and fuselage removably connect.Clamping device on the base is used for the clamping sample, and fork can be kicked up by machine power control and then make its free drop impact sample.The fork position limiting structure is between fork and the clamping device, when testing, detachable draft link position limiting structure, fork like this smoothly impact specimen carries out impulse test, when needs are changed sample, the fork stop means is contained on the fuselage, utilize it to carry out spacing to fork, so, even kick up and fall because maloperation causes fork, tup can not hurt the operating personnel that changing sample yet.
As preferably, described fork position limiting structure comprises a gag lever post, and described gag lever post one end is threaded with fuselage, and the described gag lever post other end contacts with fork.Gag lever post can be adjusted the length that it stretches to fork place end by turn, when extension elongation is enough, can stop that fork falls to horizontal level, plays a protective role; When the past convolution of gag lever post, stayed the space of passing through to fork, can carry out smoothly impulse test.
As preferably, described gag lever post is being provided with a ring groove with the fork contact position, and described fork is in the ring groove.Fork enters in the ring groove, and one can avoid double swerve excessive, and the two can provide space, a location, is convenient to control the distance that gag lever post screws in and screws out.
As preferably, described gag lever post and fuselage threaded ends are provided with rotating disk, and described rotating disk and gag lever post connect firmly, and described rotating disk is provided with swing handle, and described swing handle and gag lever post are in respectively the rotating disk both sides.But operating handle drives dial rotation, and the gag lever post turn that driven by rotary disc connects firmly with it is beneficial to operating personnel's operation of having an effect, and makes gag lever post can too much not cause dropping out outside the fuselage because screwing out distance by setting up rotating disk simultaneously, make the raising of one-piece construction stability.
Therefore, the beneficial effects of the utility model are: (1) can fall to vertical position by fork position limiting structure restriction fork when operating personnel change sample, operating personnel are protected; (2) have handle, rotating disk, convenient operation, one-piece construction stability is high.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side view.
Among the figure: base 1, fuselage 2, clamping device 3, fork 4, tup 5, gag lever post 6, rotating disk 7, swing handle 8.
Embodiment
Below by embodiment, by reference to the accompanying drawings the technical solution of the utility model is described further:
A kind of impact testing machine as shown in Figure 1 and Figure 2, comprise base 1, fuselage 2, described base 1 is provided with clamping device 3, described fuselage 2 is provided with the fork 4 with fuselage 2 upper articulations, described fork 4 lower ends are provided with tup 5, be provided with the fork position limiting structure between described fork 4 and the clamping device 3, described fork position limiting structure and fuselage 2 removably connect.Described clamping device 3 can be the tiger’s jaw pincers.Described fork position limiting structure comprises a gag lever post 6, and described gag lever post 6 one ends are threaded with fuselage 2, and described gag lever post 6 other ends contact with fork 4.Gag lever post 6 can be adjusted the length that it stretches to fork 4 place ends by turn, when extension elongation is enough, can stop that fork 4 falls to horizontal level, plays a protective role; When gag lever post 6 past convolution, stayed the space of passing through for fork 4, can carry out smoothly impulse test.Described gag lever post 6 is being provided with a ring groove with fork 4 contact positions, and described fork 4 is in the ring groove.Fork 4 enters in the ring groove, and one can avoid double swerve excessive, and the two can provide space, a location, is convenient to control the distance that gag lever post 6 screws in and screws out.Described gag lever post 6 is provided with rotating disk 7 with fuselage 2 threaded ends, and described rotating disk 7 connects firmly with gag lever post 6, and described rotating disk 7 is provided with swing handle 8, and described swing handle 8 is in respectively rotating disk 7 both sides with gag lever post 6.But operating handle drives rotating disk 7 and rotates, and rotating disk 7 drives gag lever post 6 turns that connect firmly with it, is beneficial to operating personnel's operation of having an effect, and makes the gag lever post 6 can be because screwing out apart from too much not causing dropping out outside the fuselage 2 by setting up rotating disk 7 simultaneously.
When carrying out impulse test, with sample holder on clamping device 3, swing handle 8, make gag lever post 6 rollbacks, reserve space for fork 4, by computer control, machine power input, fork 4 is kicked up to fixed angle, it is freely fallen carry out impulse test; When needs are changed sample, fork 4 is kicked up to raising in advance the angle, the turn handle makes gag lever post 6 block the space that fork 4 falls, and can carry out the replacing of sample.Even this moment have people's maloperation or since fault cause fork 4 to fall, also can be blocked, can not hurt the operating personnel that changing sample.
