Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 4, an embodiment of the present invention provides a stopper 10, where the stopper 10 includes a guide rail 100, a main rod support 200, and at least two material blocking mechanisms 300.

The guide rail 100 is usually made of metal or other materials, and the guide rail 100 usually has a groove or a ridge disposed along a certain direction, and the primary rod support 200 fixed on the guide rail 100 can move along the extending direction of the groove or the ridge by engaging with the groove or the ridge. Compared with other guide devices, the guide rail 100 can bear higher load, can bear certain torque, can realize high-precision linear motion under the condition of high load, and can better meet the use requirement on the stopper 10.

The main lever bracket 200 is slidably coupled to the guide rail 100 and has a stroke sliding in the first direction a with respect to the guide rail 100. The main rod support 200 is used for being connected with the guide rail 100 and carrying the material blocking mechanism 300 thereon, therefore, the structure, shape, size, etc. of the main rod support 200 are not limited, the main rod support 200 may be a rod, a plate, or a mixed piece formed by combining a rod and a plate, in this embodiment, the main rod support 200 of a rod is taken as an example for explanation. The connection mode between the main rod support 200 and the guide rail 100 is different according to the structure difference between the guide rail 100 and the main rod support 200, and the connection mode can be a direct connection mode such as clamping connection, and can also be an indirect connection mode by means of other movable parts. The main rod support 200 can slide along the first direction a and the direction opposite to the first direction a under the guidance of the guide rail 100, and during the installation process of the stopper 10, the first direction a can be taken as the direction approaching the material sheet on the heating furnace, the direction opposite to the first direction a can be taken as the direction away from the material sheet, and when the main rod support 200 slides along the first direction a and the direction opposite to the first direction a, the material blocking mechanism 300 on the main rod support 200 can move towards the direction approaching the material sheet and away from the material sheet respectively. The sliding of the main lever bracket 200 may be manually driven, or may be driven by a power device connected to the main lever bracket 200.

The striker 300 is the main component of the stopper 10 that serves to position the material sheet. Each of the material blocking mechanisms 300 includes a guide rod 310 and a material blocking plate 320, the guide rod 310 is slidably connected to the main rod support 200 and has a stroke sliding along a second direction b relative to the main rod support 200, and the second direction b is parallel to the first direction a. The striker plate 320 is fixedly disposed at one end of the guide rod 310 so that the striker plate 320 can slide along with the guide rod 310, the striker plate 320 has a blocking surface 321, and the blocking surface 321 is inclined to the second direction b. The number of the material blocking mechanisms 300 can be flexibly set according to the use requirement, and can be two, three, four and the like. Since the guide rod 310 is connected to the main rod holder 200, the striker plate 320 disposed at one end of the guide rod 310 may slide along the first direction a and the opposite direction of the first direction a together with the main rod holder 200. Meanwhile, the guide rod 310 has a stroke sliding along the second direction b relative to the main rod support 200, so that the striker plate 320 can slide along the second direction b and the opposite direction of the second direction b under the driving of the guide rod 310, and the second direction b is set to be parallel to the first direction a, so that the distance between the striker plate 320 and the material sheet can be adjusted through the above two different moving manners. Similar to the main lever bracket 200, the sliding of the guide lever 310 may be driven either manually or by a power device connected to the guide lever 310. It should be noted that the plurality of stock stops 300 are synchronized with the sliding of the main rod bracket 200, but the sliding of the guide rods 310 in different stock stops 300 is completely independent and does not affect each other, so the positions of the guide rods 310 and the stock stop 320 in the stock stops 300 at different positions can be separately adjusted in a targeted manner. The blocking surface 321 is inclined to the second direction b, that is, the blocking surface 321 and the second direction b form a certain included angle, which may be an acute angle, a right angle or an obtuse angle, so that the striker plate 320 can position the workpiece through the blocking surface 321.

The embodiment of the utility model provides a stopper 10 is when using, can be at first through mobile jib support 200 the slip coarse tune all stock stop 300's position on guide rail 100, come the position of fender 320 on the stock stop 300 of different positions departments of pertinence ground fine tuning through the slip of guide arm 310 on mobile jib support 200 afterwards, the commonality of stopper 10 has been improved, the accurate degree of stopper 10 positioning position regulation has both been guaranteed, multiple times of repeated adjustment has been avoided again, and the production efficiency is improved.

When the position of the material blocking plate 320 on each material blocking mechanism 300 is finely adjusted, in order to avoid mutual influence and even interference among a plurality of material blocking structures, the position arrangement of each material blocking mechanism 300 needs to meet a certain condition. Since the striker plates 320 of the stock stop mechanisms 300 slide in the second direction b and the direction opposite to the second direction b, and the second direction b is parallel to the first direction a, in one embodiment, each stock stop mechanism 300 is arranged in a linear array along the length direction of the master rod support 200, and the length direction of the master rod support 200 is perpendicular to the second direction b. Therefore, the arrangement direction of each striker 300 is perpendicular to the sliding direction of the striker plates 320, and the striker plates 320 do not affect each other during sliding. The spacing between the retaining mechanisms 300 can be flexibly adjusted according to the use requirement and the length of the main rod support 200, and is not limited herein.

As described above, the connection manner between the guide rod 310 and the main rod holder 200 is different according to the structure of the guide rod 310 and the main rod holder 200. For example, a guide may be provided on the main lever bracket 200, and the guide bar 310 may be slidably coupled to the guide by means of a snap fit or the like. Referring to fig. 4, in an embodiment, the material blocking mechanism 300 may further include a limiting portion 330, the main rod bracket 200 is provided with a guide hole, the guide hole penetrates through the main rod bracket 200 along the second direction b, the guide rod 310 penetrates through the guide hole, and the limiting portion 330 is detachably disposed at an end of the guide rod 310 far away from the material blocking plate 320, so that the limiting portion 330 can block the guide rod 310 from being separated from the guide hole. The guide rod 310 is fixed by directly forming the guide hole on the main rod support 200, which saves processing materials and is convenient to install compared with a structure adopting a guide member. The limiting part 330 serves to prevent the guide rod 310 from being separated from the guide hole, and therefore, the structure of the limiting part 330 has no specific requirement, and only the projection of the limiting part 330 on the main rod bracket 200 along the second direction b is required to completely cover the guide hole. In this embodiment, in order to enhance the stability of the striker plate 320, three guide rods 310 are respectively adopted in each striker mechanism 300 to connect the left end and the right end of the striker plate 320 and the central region, and therefore, the limiting portion 330 can be a connecting rod which connects the three guide rods 310 at one end of each guide rod 310 far away from the striker plate 320, and plays roles of limiting and fastening.

After the position of the striker plate 320 is adjusted, the striker plate 320 needs to be fixed so as to perform subsequent striker operation, therefore, in an embodiment, the striker mechanism 300 further includes a linear bearing 340 and a first fastener 350, along the second direction b, the linear bearing 340 is disposed at one end of the main rod support 200 far away from the striker plate 320 and abuts against the main rod support 200, the linear bearing 340 has a shaft hole 341 capable of communicating with the guide hole, the guide rod 310 sequentially penetrates through the shaft hole 341 and the guide hole, a first screw hole 342 communicating with the shaft hole 341 is formed on the outer peripheral wall of the linear bearing 340, the first fastener 350 includes a first screw thread section 351 matched with the first screw hole 342, the first screw thread section 351 can be screwed into the shaft hole of the first screw hole 342 to block the guide rod 310 from sliding along the main rod support 200. When the first thread section 351 is screwed into the shaft hole 341 through the first screw hole 342, the end of the first thread section 351 abuts against the outer peripheral wall of the guide rod 310, and a positive pressure is applied to the guide rod 310, so that the guide rod 310 is influenced by friction when sliding. As the first thread section 351 extends further into the axial hole 341, the friction force applied to the guide rod 310 increases until the guide rod cannot slide. By screwing the first thread section 351 out of the shaft hole 341, the guide rod 310 is free from the influence of friction force and can slide normally. The position of the guide bar 310 and the striker plate 320 can be fixed during fine adjustment by the first fastening member 350.

Similarly, a fastening member may be disposed on the main rod bracket 200 to fix the main rod bracket 200, in an embodiment, the stopper 10 further includes a second fastening member 400, the main rod bracket 200 is formed with a second screw hole 220 therethrough, the second fastening member 400 includes a second screw thread section 410 engaged with the second screw hole 220, and the second screw thread section 410 may be screwed into the second screw hole 220 to abut against the surface of the guide rail 100, so as to prevent the main rod bracket 200 from sliding along the guide rail 100. Screwing the second screw section 410 into abutment with the surface of the guide rail 100 through the second screw hole 220 applies a positive pressure to the guide rail 100, and the guide rail 100 applies a reaction force to the primary lever bracket 200, and the primary lever bracket 200 is influenced by friction while sliding. As the second thread section 410 is further advanced, the friction of the main rod support 200 is increased until the main rod support cannot slide. And the second thread section 410 is screwed out not to abut against the surface of the guide rail 100, so that the main rod bracket 200 is not affected by friction and can slide normally.

To further improve the accuracy of the positioning of the striker plate 320, the distance that the guide rod 310 slides may be recorded or calculated, for example, in one embodiment, the guide rod 310 is provided with a scale mark. Since the guide bar 310 slides relative to the main bar bracket 200, a zero scale of the scale marks may be set at a position where the guide bar 310 intersects with the main bar bracket 200 in an initial state (i.e., when the guide bar 310 does not slide), so that after the guide bar 310 slides, the sliding distance of the guide bar 310 can be known by reading the scale marks at the contact position of the main bar bracket 200 and the guide bar 310. In another embodiment, the material blocking mechanism 300 further includes a scale slidably connected to the rod support 200 and having a sliding stroke along the second direction b relative to the rod support 200, the length direction of the scale is parallel to the second direction b, and one end of the scale is connected to the material blocking plate 320. The gauge is additionally arranged on the material blocking mechanism 300 and synchronously slides along with the guide rod 310, and the sliding distance of the guide rod 310 can be read at any time by reasonably setting the scale starting point of the gauge. The graduated scale can adopt a digital display graduated scale to facilitate reading.

The boom support 200 slides with respect to the guide rail 100, and each of the stock stops 300 is disposed on the boom support 200, so that stability when the boom support 200 slides needs to be ensured, and for this reason, in one embodiment, the number of the guide rails 100 is two, the two guide rails 100 are disposed in parallel, and along the length direction of the boom support 200, both ends of the boom support 200 are slidably connected with the two guide rails 100, respectively. Thus, the connection of the main lever bracket 200 is more stable and can be more stable when sliding. And the guide rails 100 are located at both ends of the main rod support 200, so that the normal operation of the stock stop mechanism 300 is not affected by blocking.

In some embodiments, the guide rail 100 has a rack 110 on one surface, and the main rod bracket 200 has a gear 210 engaged with the rack 110. And the main rod support 200 is further provided with an encoder, and the encoder is connected with the central hole of the gear 210 through an output shaft. This configuration not only facilitates the sliding of the boom housing 200, but also facilitates the recording of the distance the boom housing 200 slides relative to the guide rail 100 by the encoder. The encoder is a rotary sensor for converting rotary displacement into a series of digital pulse signals, these pulse signals can be used for controlling angular displacement and measuring linear displacement, and can be directly inputted into PLC (Programmable Logic Controller), and its pulse signals can be counted by utilizing high-speed counter of PLC so as to obtain the measurement result.

In order to facilitate the installation and alignment of the blocking mechanism, in one embodiment, the blocking device 10 further includes a lifting bracket 500, the lifting bracket 500 has a movable end capable of being lifted, and the movable end is connected to the guide rail 100 to drive the guide rail 100, the main rod bracket 200, and the material blocking mechanism 300 to be lifted. In different use occasions, the height of the blocking mechanism relative to the installation surface is different, so that the guide rail 100, the main rod support 200 and the height of the material blocking mechanism 300 carried on the main rod support 200 relative to the installation surface can be flexibly adjusted by arranging the lifting support 500 capable of lifting, the blocking device 10 in the embodiment can be suitable for various different scenes, and the application range of the blocking device 10 is improved.
