Background

The translation mechanism is usually used to enable the two devices to perform the relative translational motion, but since the translation mechanism generally has two components performing the translational motion with each other, the two components may wear, and especially when the translation mechanism is used to carry a device with a large mass, the wear between the two components may be more significant, and the wear rate may be faster.

In the prior art, a wear plate is generally disposed between two assemblies which move in a translational manner, so as to avoid wear of the two assemblies, thereby achieving the purpose of improving economic efficiency. However, when the wear plate has a plurality of inner surfaces, and at least two of the inner surfaces face each other, wear of the wear plate may result in a gap between the translating assembly and the wear plate, which may result in wobbling of the translating mechanism during translational movement. Even if the gap between the wear plates and the components of the translation mechanism is adjusted, it is not possible to have each surface of the wear plates abut closely against the translation mechanism, especially not both facing inner surfaces of the wear plates.

Detailed Description

The present application will be described in detail with reference to specific embodiments.

Fig. 1 to 3 show an embodiment of a wear-resistant structure suitable for use in a translation mechanism, which mainly comprises a slideway 82, a guide rod 81 and a wear-resistant plate 83, wherein the guide rod 81 is slidably disposed in the slideway 82, the wear-resistant plate 83 is disposed between the guide rod 81 and the slideway 82, the slideway 82 has a cross section of '21274', the guide rod 81 has a rectangular cross section, the wear-resistant plate 83 is of a split design, and comprises a first wear-resistant plate 83a and a second wear-resistant plate 83b from top to bottom, and the first wear-resistant plate 83a and the second wear-resistant plate 83b are spaced up and down. It should be understood that the orientation of the first wear plate 83a and the second wear plate 83b, which are arranged in spaced sequence from bottom to top, left to right, or right to left, is immaterial and within the scope of the present application, and the above embodiments are only intended to be limited in orientation for convenience of description.

At this time, a space is provided between the first wear plate 83a and the second wear plate 83b for the two to move toward each other, wherein,

a pressing member is provided above the first wear plate 83a, and presses the first wear plate 83a downward when the upper and lower inner surfaces of the wear plate 83 are worn. Since the wear plates 83 are separated and spaced from each other, there is a space for the first wear plate 83a to move downward, so that the first wear plate 83a can move downward to a position abutting against the guide bar 81. This configuration maximizes the use of the wear plate 83, and eliminates the need to frequently replace the wear plate 83, as compared to a wear plate that is not separately designed.

It can be easily understood that, since the second wear plate 83b is located below the guide rods 81, when the lower inner surface of the second wear plate 83b is worn, the guide rods 81 automatically move downward under the action of gravity, so that it is not necessary to provide a pressing member below the second wear plate 83b, and only a pressing member needs to be provided above the first wear plate 83a, and in addition, in order to maintain the side portion of the wear plate 83 in a state of abutting against the guide rods 81, a pressing member may be provided on the outer side surface of the wear plate 83 to maintain the inner side surface of the wear plate 83 in a state of abutting against the guide rods 81.

The wear plate 83 has an inner abutment surface 831 composed of an inner surface 831a of the upper pad 83 and an inner surface 831b of the lower pad 83b, and an outer abutment surface 832 composed of an outer surface 832a of the upper pad 83a and an outer surface 832b of the lower pad 83b,

in one embodiment, the biasing member is configured as a threaded bolt having a threaded through hole disposed at an upper portion of the slide 82 and corresponding to the first wear plate 83a, through which the bolt is biased against the first wear plate 83 a. Correspondingly, threaded through holes may be provided at the sides of the slide 82 and corresponding to the wear plates 83, through which threaded through holes bolts are passed to abut against the sides of the backing plates 83 a. In the embodiment shown in fig. 1, 4 bolts are provided above the first wear plate 83 adjacent to the two ends, respectively, for a total of 8 bolts, and 8 bolts are provided at the side of the wear plate 83, so that the wear plate 83 can be held against the guides 81 at a plurality of angles.

In another embodiment, the biasing member is configured as a resilient element, such as a spring, which is disposed in compression between the slide 82 and the first wear plate 83a, and which biases the first wear plate 83a towards the guide 81 when the upper and/or lower inner surfaces of the wear plate 83 are worn. Similarly, a spring may be provided between the side of the wear plate 83 and the slide 82 to automatically adjust the gap between the side of the wear plate 83 and the guide 81.

When the first wear plate 83a and the second wear plate 83b rub against the guide 81, since the first wear plate 83a and the second wear plate 83b are L-shaped in cross section, the wear plates will be blocked by the guide 81 and have no freedom to disengage towards the opening, and the wear plates 83 may disengage towards the opening of the slide 82. For better use of the wear plate 83, an abutment plate 84 is provided between the wear plate 83 and the slideway 82, the abutment plate 84 being generally L-shaped in cross-section and extending from the upper portion of the first wear plate 83a around to the side of the second wear plate 83b so that the biasing elements no longer directly contact the wear plate 83 but rather transmit thrust to the wear plate 83 through the abutment plate 84, reducing the likelihood of damage to the wear plate 83.

It should be appreciated that the wear plate 83 may preferably be made of a nylon material having good wear properties. Referring to fig. 4, the wear plate 83 may be provided with corresponding blocking means at the front and rear ends thereof, which limit the longitudinal movement of the wear plate 83 when the slide 82, the wear plate 83 and the guide 81 are slidably engaged with each other, so that there is no relative axial movement between the wear plate 83 and the slide 82 when the guide 81 slides, thereby achieving the function of the guide 81 sliding on the slide 82. Further, the blocking means 88 simultaneously limits the freedom of axial movement of the wear plate 83 and the abutment plate 84 when the abutment plate 84 is disposed between the wear plate 83 and the slideway 82.
