Description

Technical Field

[0001] This utility model relates to the field of plunger manufacturing technology, and in particular to a rod sawing support device for plunger manufacturing. Background Technology

[0002] A plunger is a mechanical part, usually cylindrical, used in hydraulic systems such as hydraulic cylinders and plunger pumps to transfer and convert energy through reciprocating motion. For example, in a plunger pump, the plunger's movement generates pressure, transporting fluid from a low-pressure area to a high-pressure area.

[0003] The raw material for plunger production is generally cylindrical bar stock. Depending on the required plunger size, the bar stock needs to be sawn to a fixed length. The sawing process not only requires limiting and fixing the bar stock, but also requires effective support at the bottom of the bar stock to create a large gap between it and the sawing table surface, so as to facilitate the movement of the sawing tool. Existing clamping devices only focus on limiting and fixing the bar stock, and do not pay attention to supporting its bottom. This makes it difficult for the tool to saw at the bottom of the bar stock, affecting the processing work. Furthermore, the lack of necessary support after sawing the bar stock can easily cause one end to tilt up, making it difficult to remove the material and posing certain safety hazards. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing a rod sawing support device for plunger production.

[0005] This utility model is achieved through the following technical solution:

[0006] A rod sawing support device for plunger production includes a sawing table, a limiting seat, a locking strip, a side limiting mechanism, a guide tube, and an end support mechanism. The limiting seat is fixedly connected to both ends of the top of the sawing table. The locking strip is fixedly disposed inside the limiting seat. The side limiting mechanism is locked at the top of the locking strip. The guide tube is fixedly disposed inside the locking strip. The end support mechanism is locked inside the guide tube. The side limiting mechanism includes a locking seat, a support seat, and a limiting rod. The support seat is fixedly disposed at the top of the locking seat, and the limiting rod is locked at the outside of the locking seat.

[0007] In a preferred embodiment of this utility model, the end support mechanism includes a guide rod, a sliding seat, a roller, a tube, a screw, a limiting nut, and a locking block. The sliding seat is fixedly disposed at one end of the guide rod, the roller is movably connected to the inner bottom of the sliding seat, the tube is fixedly disposed at the top of the sliding seat, the screw is locked at the top of the tube, the limiting nut is threadedly connected to the screw, and the locking block is fixedly disposed at the top of the screw.

[0008] The end support mechanism mainly provides effective support for the non-cut end of the bar, ensuring that the bottom of the non-cut end is supported at the same height, thereby preventing the cut bar from falling.

[0009] In a preferred embodiment of the present invention, the top of the card strip is provided with a serrated card groove, and the inner side of the top of the card seat is provided with a card tooth that cooperates with it.

[0010] After the teeth on the inner side of the top of the card holder engage with the serrated groove on the top of the card strip, the support seat is effectively prevented from moving to both sides due to pressure from the bar stock, thus ensuring the support effect of the support seat.

[0011] In a preferred embodiment of the present invention, the card holder surface and the card strip surface are provided with insertion holes that cooperate with the limiting insertion rod, and one end of the limiting insertion rod passes through the card holder and the card strip and extends to the outside of one side of the card holder;

[0012] By placing the limiting rod in the insertion hole on the surface of the card holder and the surface of the card strip, not only is it prevented from moving outward under pressure, but it is also prevented from tilting up the side limiting mechanism.

[0013] In a preferred embodiment of this utility model, the top of the insertion tube is provided with a locking hole that cooperates with the screw, and the bottom of the limiting nut contacts the upper surface of the insertion tube.

[0014] The beneficial effects of this utility model are:

[0015] This bar sawing support device provides effective support at the bottom of the bar. The position of the side limiting mechanism can be adjusted according to the bar diameter, and the side limiting mechanism can be effectively fixed, so that there is a reasonable gap between the bottom of the bar and the sawing table to facilitate sawing. The end support mechanism can adjust the support height so that the top of the support mechanism contacts the bottom of the non-sawed end of the bar, preventing one end from falling or even the bar from rolling down after sawing, thus improving the safety of equipment use.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0021] like Figure 1-3 The illustrated rod sawing support device for plunger production includes a sawing table 1, a limiting seat 2, a clamping strip 3, a side limiting mechanism 4, a guide tube 5, and an end support mechanism 6. The limiting seat 2 is fixedly connected to the top two ends of the sawing table 1. The clamping strip 3 is fixedly disposed inside the limiting seat 2. The side limiting mechanism 4 is clamped on the top of the clamping strip 3. The guide tube 5 is fixedly disposed inside the clamping strip 3. The end support mechanism 6 is clamped inside the guide tube 5. The side limiting mechanism 4 includes a clamping seat 41, a support seat 42, and a limiting rod 43. The support seat 42 is fixedly disposed on the top of the clamping seat 41, and the limiting rod 43 is clamped on the outside of the clamping seat 41.

[0022] Specifically, the end support mechanism 6 includes a guide rod 61, a sliding seat 62, a roller 63, an insertion tube 64, a screw 65, a limiting nut 66, and a locking block 67. The sliding seat 62 is fixedly installed at one end of the guide rod 61. The roller 63 is movably connected to the inner bottom of the sliding seat 62. The insertion tube 64 is fixedly installed at the top of the sliding seat 62. The screw 65 is locked at the top of the insertion tube 64. The limiting nut 66 is threadedly connected to the screw 65. The locking block 67 is fixedly installed at the top of the screw 65. The top of the locking strip 3 has a serrated groove. The inner top of the locking seat 41 has a locking tooth that mates with it. The surface of the locking seat 41 and the surface of the locking strip 3 have insertion holes that mate with the limiting insertion rod 43. One end of the limiting insertion rod 43 passes through the locking seat 41 and the locking strip 3 and extends to the outside of one side of the locking seat 41. The top of the insertion tube 64 has a locking hole that mates with the screw 65. The bottom of the limiting nut 66 contacts the upper surface of the insertion tube 64.

[0023] In this embodiment, two sets of limiting seats 2 are provided on the top of the sawing table 1. The limiting seats 2 are fixed to the surface of the sawing table 1 by bolts. The locking strip 3 is fixedly set on the inner side of the limiting seat 2. Then, the side limiting mechanism 4 is adjusted according to the diameter of the bar. The bottom of the locking seat 41 is provided with a locking groove that cooperates with the locking strip 3. After the locking seat 41 is lifted upward, the position of the side limiting mechanism 4 can be adjusted on the top of the locking strip 3. After the locking seat 41 is lowered, the tooth groove at its bottom will engage with the locking teeth at the top of the locking strip 3, thereby preventing the support seat 42 from sliding on the surface of the locking strip 3 after being subjected to pressure. When the inner tooth groove at the top of the locking seat 41 engages with the locking teeth at the top of the locking strip 3, the insertion hole on the surface of the locking seat 41 and the surface of the locking strip 3 will be connected. In order to further achieve the fixing effect, the limiting insertion rod 43 is locked into the insertion hole to effectively prevent the side limiting mechanism 4 from moving backward or the end from tilting up.

[0024] Furthermore, the bar is lifted and placed on top of the support base 42. The sawing position is located between the two clamps 41. After the bar is placed, there is a certain gap between its bottom and the upper surface of the sawing table 1. At this time, the end support mechanism 6 is adjusted, and the sliding seat 62 is pulled outward. The roller 63 at the bottom of the sliding seat 62 facilitates the movement of the sliding seat 62. The guide rod 61, which is locked in the guide tube 5, guides the movement of the sliding seat 62 and supports one end of the guide rod 61. Then, the limiting nut 66 on the surface of the screw 65 is adjusted so that the screw 65 is locked to the top of the insertion tube 64 at a different depth until the top clamping block 67 of the screw 65 contacts the bottom outer side of the non-sawing end of the bar, thereby achieving a supporting effect. In this way, after the sawing equipment cuts the bar, the cut bar will not roll randomly and effectively prevent one end of the bar from tilting up, achieving an effective supporting effect. Moreover, the lifted bar is convenient for transportation.
