Abstract
The utility model discloses an anchor clamps seal for glass tube and stem stem, the stem stem includes stem stem calandria and stem stem pin, seal anchor clamps including the link of locating anchor clamps one end and being used for being connected with sealing equipment, it still is used for going into the installation of stem stem calandria direction sealing equipment's guider and locating the fixing device that the anchor clamps other end is used for installing the stem stem pin in locating anchor clamps to seal anchor clamps. The utility model provides an anchor clamps seal for glass tube and stem stem convenient to use greatly improves and seals the qualification rate, has reduced and has done over again and scrap, has shortened production cycle, has reduced manufacturing cost to the performance of negative pole and device has been ensured.
Description
Technical field
The utility model belongs to clamp art, is specifically related to a kind of seal clamp for glass-tube and stem stem.
Background technology
Barium-tungsten dispense cathode is widely used in modern microwave device, and as electron source electron emission, be microwave device " heart ", its quality and performance directly affects key performance and the index of device.Usually, in order to reduce the negative electrode processing time in the devices, reduce the discharge quantity of negative electrode and reduce negative electrode evaporation etc. in the devices, when preparing barium-tungsten dispense cathode, can negative electrode be arranged on stem stem, and carry out the sealing of stem stem and glass-tube, afterwards on cathode exhaust gas platform, under the condition of vacuum, carry out the preliminary treatment of negative electrode.Sealing need guarantee that the perfection of glass-tube and stem stem is merged, and possesses vacuum tightness, and due to the particularity of glass, if the internal stress produced when sealing is comparatively large, in the process or storage process in later stage, sealing part also there will be cracking, destroys vacuum, makes cathode degradation.Existing fixture seals, and qualification rate is low, and sealing part often occurs crack, cannot ensure air-tightness, causes and does over again or even the scrapping of product, extend the production cycle, add production cost, and reduce the performance of negative electrode and device.
Summary of the invention
The utility model is intended at least to solve one of technical problem existed in prior art.For this reason, the utility model provides a kind of seal clamp for glass-tube and stem stem, and object improves the qualification rate of sealing.
To achieve these goals, the technical scheme that the utility model is taked is:
A kind of seal clamp for glass-tube and stem stem, described stem stem comprises stem stem comb and stem stem pin, described seal clamp comprises is located at fixture one end and link for being connected with sealing device, and described seal clamp also comprises to be located in fixture for stem stem comb guiding being fit into the guider of sealing device and being located at the fixture that the fixture other end is used for mounting core column jecket pin.
Preferably, the structure that is formed in one of described seal clamp.
Preferably, described guider is through hole, and the internal diameter of through hole is greater than the external diameter of stem stem comb.
Preferably, the height of described through hole is greater than the length of stem stem comb.
Preferably, described fixture is interior counterbore, and the internal diameter of interior counterbore is greater than the circle diameter of stem stem pin.
Preferably, the degree of depth of described interior counterbore is greater than the length of stem stem pin.
Preferably, the external diameter of described seal clamp 1-5mm less of the external diameter of stem stem.
The beneficial effects of the utility model: the seal clamp for glass-tube and stem stem that the utility model provides is easy to use, greatly improve sealing qualification rate, decrease and do over again and scrap, shorten the production cycle, reduce production cost, and ensure the performance of negative electrode and device.
Accompanying drawing explanation
This specification comprises the following drawings, shown content respectively:
Fig. 1 is seal clamp structural representation of the present utility model.
Be labeled as in figure:
1, link, 2, through hole, 3, interior counterbore, 4, screw thread.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, be described in further detail embodiment of the present utility model, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present utility model, technical scheme, and contribute to its enforcement.
As shown in Figure 1, a kind of seal clamp for glass-tube and stem stem of the utility model, wherein stem stem comprises stem stem comb and stem stem pin, seal clamp comprises is located at fixture one end and link 1 for being connected with sealing device, and seal clamp also comprises to be located in fixture for stem stem comb guiding being fit into the guider of sealing device and being located at the fixture that the fixture other end is used for mounting core column jecket pin.
Be preferably, the mode that above-mentioned fixture one end is connected with sealing device is thread connecting mode.As shown in Figure 1, screw thread 4 is set outside link, in order to be spirally connected with sealing device.
In order to use fixture of the present utility model more easily, adopt the structure that seal clamp is formed in one.
Preferably, guider is through hole 2, and the internal diameter of through hole 2 is greater than the external diameter of stem stem comb.The insertion being convenient to stem stem comb is installed, and is advisable than the large 1-3mm of the external diameter of stem stem comb with the internal diameter of through hole; Through hole is preferably disposed on the centre position of fixture, that is to say be positioned at fixture central axis direction on arrange.The height of through hole 2 is preferably arranged to the length being greater than stem stem comb; This kind of structure is conducive to stem stem comb and is in more stable state in through-holes, avoids the situation causing stem stem comb to ftracture.
Above-mentioned fixture can be interior counterbore 3, and the internal diameter of interior counterbore 3 is greater than the circle diameter of stem stem pin, and the insertion being convenient to stem stem pin is installed, within the internal diameter of counterbore 3 be advisable than the large 1-3mm of the circle diameter of stem stem pin; The degree of depth of interior counterbore 3 is greater than the length of stem stem pin, is conducive to the stable of stem stem like this.
Preferably, the external diameter of seal clamp 1-5mm less of the external diameter of stem stem.The blanking of glass-tube when this structure is conducive to sealing.
Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; Or without improvement, above-mentioned design of the present utility model and technical scheme directly applied to other occasion, all within protection range of the present utility model.
